    Full Text Available Pomegranate (Punica granatum L. is an ancient fruit tree traditionally cultivated in the Near and Middle East. Presently, its most important growing regions include Afghanistan, Iran, Israel, USA, Italy and Spain, the latter country the largest European exporter. The pomegranate fruit can be divided into several anatomical compartments: outside peel, inside peel, and arils (pulp and seeds, the last part being usually used for consumption as is or for juice, jams and jellies production. Even though pomegranate seeds are an industrial by-product, recent reports have highlighted their potential use as a source of oil with beneficial chemical attributes. Therefore, the main objective of the present work was to characterize the seed oil of nine European pomegranate varieties, collected in Spain, for their fatty acid and vitamin E compositions. All seed lipid fractions consisted mainly of punicic acid (c9,t11,c13 C-18:3, ranging between 77.3% and 83.6% of total fatty acids, followed by small amounts of linoleic acid (C18:2n6, oleic acid (C18:1n9 and palmitic acid (C16:0. Regarding vitamin E composition, α-, γ-, δ-tocopherols were found in all pomegranate seed oils, but mainly γ-tocopherol, with total tocopherols ranging from 174.5 to 627.3 mg/100g oil.The richness of these pomegranate varieties seed oils in punicic acid, a conjugated linolenic acid with interesting anti-carcinogenic activity, and the elevated amount of tocopherols on the extracted lipids, of technological and nutritional relevance, make this by-product interesting for further exploitation.

    Rind of Punica granatum is traditionally used in treatment of abdominal cramps and various GIT disorders. So far spasmolytic activity of rind of Punica granatum has been reported using in vitro model. However, its mode of action is not explored yet. Therefore, the current work describes the possible mode of action for spasmolytic activity of methanolic extract of rind of Punica granatum (Pg. Cr). Acute toxicity study is also performed to determine its safe dose range. Rind of Punica granatum was subjected to shade drying. Shade dried materials were pulverized using conventional grinder. Grinded materials were macerated in commercial grade methanol. The extract of rind of P. granatum was concentrated using a rotary evaporator. Rabbits' jejunal preparations were mounted in organ bath containing 10 ml Tyrode's solution, constantly aerated with carbogen gas. Pg. Cr was tested on spontaneous rabbits' jejunal preparations in concentrations 0.01, 0.03, 0.1, 0.3, 1.0, 3.0, 5.0 and 10.0 mg/ml. Pg. Cr was also tested on KCl (80 mM)-induced contractions in rabbits' jejunal preparations. Since we observed spasmogenic activity for the first time, hence we also determined the effects of Pg. Cr in presence of atropine (0.03 μM). Pg. Cr was also tested in presence of 0.03 μM of loratadine HCl. Pg. Cr was also tested on barium chloride induced contractions. Calcium Concentration Response Curves (CCRCs) were constructed in the absence and presence of test samples of Pg. Cr in decalcified tissues to explore its possible mode of action. Acute toxicity screening was also performed to determine its safe dose range. Phytochemical screening revealed the presence of saponins, tannins, carbohydrates, proteins, flavonoids, saponins and steroids. However, Pg. Cr tested negative for alkaloids and triterpenoids. Pg. Cr was safe up to 100 mg/kg with its LD 50 = 1305 mg/kg. Its respective EC 50, in the absence and presence of atropine, were 9.7 ± 0.3 and 3.12 ± 0.45 mg/ml. In

    Pomegranate (Punica granatum L.) has been cultivated from ancient times for its economic, ornamental and medicinal properties globally. Here, we report the isolation and characterization of 12 polymorphic microsatellite markers from a repeat-enriched genomic library of Punica granatum L. The genetic diversity of these loci was assessed in 60 genotypes of Punica granatum L. All loci were variable: the number of polymorphic alleles per locus ranged from two to five (average 2.9). The observed and expected heterozygosities ranged from 0.15 to 0.87 and 0.29 to 0.65, respectively. The polymorphic information content ranged from 0.26 to 0.61 (average: 0.43). To the best of our knowledge, this is the first time that polymorphic microsatellite markers have been reported for P. granatum L. These new markers should allow studies of the population structure and genetic diversity of pomegranate to be performed in the future.

    Full Text Available Background: Periodontal diseases are chronic bacterial infections that lead to gingival inflammation, periodontal tissue destruction, and alveolar bone loss. Acting as powerful allies in the fight against periodontal disease, natural compounds can help safeguard against lethal age-related diseases that emanate from our mouths. Punica granatum (pomegranate shrub belongs to the Punicaceae family which has been used as an astringent, hemostatic, antidiabetic, antihelmintic, and also for diarrhea and dysentery. The aim of the present work was to investigate the possible efficacy of hydroalcoholic extract from Punica granatum fruit as an antiplaque and antigingivitis agent when compared with chlorhexidine. Materials and Methods: Twenty subjects diagnosed with chronic generalized gingivitis were selected and randomly divided into two groups: Group 1 - Pomegranate mouthwash and Group 2 - Chlorhexidine mouthwash. Punica granatum mouthwash was prepared using raw Punica granatum fruit. Patients were instructed to use the prescribed mouthwash for 15 days. Clinical evaluation was undertaken using the gingival index, the plaque index, and bleeding on probing at baseline, 7 days, and 15 days. Results: The clinical study observed significant improvement in gingival status in both the sites (P<0.05. Subjects using Punica granatum mouthwash showed significant improvement in bleeding and gingivitis score as compared with chlorhexidine. In contrast, Punica granatum was shown not to be so effective in reducing plaque scores. Chlorhexidine still remains as a standard in the reduction of plaque in subjects with gingivitis. Conclusion: Punica granatum mouthwash is beneficial in improving gingival status due to its profound styptic action, with sufficient reduction in plaque scores.

    In the interests of food safety and public health, plants and their compounds are now re-emerging as an alternative approach to treat parasitic diseases. Here, we studied the anticoccidial effect of different solvent extracts of the fruit peel of Punica granatum-a commercial waste from pomegranate juice industries. The hope underlying these experiments was to find a sustainable natural product for controlling coccidiosis. The plant extracts were prepared using solvents of different polarity. Acute oral toxicity study was first carried out to see the safety of crude extracts. A high dose of crude extracts (300 mg/kg body weight) was tested for possession of anticoccidial activity against experimentally induced coccidial infection in broiler chicken. Activity was measured in comparison to the reference drug amprolium on the basis of oocyst output reduction, mean weight gain of birds and feed conversion ratio. Oocyst output was measured using Mc-Masters counting technique. Acute oral toxicity study showed that crude extracts of P. granatum are safe up to dosage of 2000 mg/kg body weight. LD 50 was not determined as mortalities were not recorded in any of the five groups of chicken. For anticoccidial activity crude methanolic extract (CME) of the fruit peel of P. granatum showed the maximum effect as evident by oocyst output reduction (92.8 ± 15.3), weight gain of birds (1403.0 ± 11.9 g) and feed conversion ratio (1.66 ± 0.04), thereby affirming the presence of alcohol soluble active ingredients in the plant. We also tested different doses (100-400 mg/kg body weight) of the CME of the fruit peel of P. granatum, the most active extract on E. tenella and observed a dose dependent effect. From the present study it can be concluded that alcoholic extract of the fruit peel of P. granatum has significant potential to contribute to the control of coccidian parasites of chicken.

    Acne is a common skin condition with sebum overproduction, hyperkeratosis, Propionibacterium acnes ( P . acnes ) and Staphylococcus aureus , and inflammation. Punica granatum (pomegranate) is well-known for its anti-inflammatory effects; however, few studies have discussed the anti-acne effects of pomegranate. In this study, we found that pomegranate extract (PG-E) significantly reduced P . acnes -induced edema in Wistar rat ears. Therefore, an evaluation platform using multiple pathogenic mechanisms of acne was established to explore the anti-acne effects of pomegranate. Results showed that PG-E inhibited bacterial growth and lipase activity. Through a bioguided-fractionation-isolation system, four hydrolysable tannins, punicalagin ( 1 ), punicalin ( 2 ), strictinin A ( 3 ), and granatin B ( 4 ), were isolated. Compounds 1 and 2 had greater anti-bacterial activities and anti-testosterone-induced HaCaT proliferative effects than the others. Compounds 1 , 3 , and 4 displayed lipase inhibitory effects. Compound 4 decreased cyclooxygenase-2 expression and downregulated prostaglandin E₂ production in heat-killed P . acnes -treated RAW 246.7 cells. In conclusion, PG-E is abundant in hydrolysable tannins that display multiple anti-acne capacities, including anti-bacterial, anti-lipase, anti-keratinocyte proliferation, and anti-inflammatory actions. Hence, PG-E has great potential in the application of anti-acne and skin-care products, and punicalagin ( 1 ), the most effective component in PG-E, can be employed as a quality control marker.

    Dementia is one of the age related mental problems and characteristic symptom of various neurodegenerative diseases including Alzheimer's disease. This impairment probably is due to the vulnerability of the brain cells to increased oxidative stress during aging process. Many studies have shown that certain phenolic antioxidants attenuate neuronal cell death induced by oxidative stress. The present work was undertaken to assess the effect of ethanolic extract of Punica granatum seeds on cognitive performance of aged and scopolamine treated young mice using one trial step-down type passive avoidance and elevated plus maze task. Aged or scopolamine treated mice showed poor retention of memory in step-down type passive avoidance and in elevated plus maze task. Chronic administration (21 days) of Punica granatum extract and vitamin C significantly (p Punica granatum extract also significantly lowered lipid peroxidation level and increased antioxidant glutathione level in brain tissues. Punica granatum preparations could be protective in the treatment of cognitive disorders such as dementia and Alzheimer's disease.

    To determine the protective role of Punica granatum L. (Punicaceae) seed juice extract and its butanolic fraction on heart rate, electrocardiographic patterns, vascular reactivity to catecholamines, cardiac marker enzymes, antioxidant enzymes together with morphologic and histopathological changes in isoproterenol-induced myocardial infarction in male Wistar rats. The effects of Punica granatum seed juice extract (100 mg/kg, p.o. and 300 mg/kg, p.o.) and butanolic fraction of Punica granatum seed juice extract (100 mg/kg., p.o.) on cardiac parameters were studied. Isoproterenol hydrochloride was used to induce myocardial infarction in Wistar rats. At the end of the experiment, heart rate, ECG, pressure rate index and cardiac marker enzyme levels were assessed. Rats treated with isoproterenol (85 mg/kg, administered subcutaneously twice at an interval of 24 h) showed a significant increase in heart rate, ST elevation in ECG, pressure rate index and a significant increase in the levels of cardiac marker enzymes- lactate dehydrogenase, and creatine kinase in serum. Isoproterenol significantly reduced superoxide dismutase and catalase activity and increased vascular reactivity to various catecholamines. Pretreatment with PJ (100 mg/kg, p.o. and 300 mg/kg, p.o.) and B-PJ (100 mg/kg., p.o.) for a period of 21 days significantly inhibited the effects of ISO on heart rate, PRI, ECG patterns, levels of LDH, CK, SOD, CAT, and vascular reactivity changes. Treatment with PJ (100 mg/kg and 300 mg/kg) and B-PJ (100 mg/kg., p.o.) alone did not alter any of the parameters as compared to vehicle-treated Wistar rats. Punica granatum-treated animals showed a lesser degree of cellular infiltration in histopathological studies. Punica granatum ameliorates cardiotoxic effects of isoproterenol and may be of value in the treatment of MI.

    Pomegranate (Punica granatum L.) is a perennial fruit crop grown since ancient times that has been planted worldwide and is known for its functional metabolites, particularly punicalagins. We have sequenced and assembled the pomegranate genome with 328 Mb anchored into nine pseudo-chromosomes and annotated 29 229 gene models. A Myrtales lineage-specific whole-genome duplication event was detected that occurred in the common ancestor before the divergence of pomegranate and Eucalyptus. Repetitive sequences accounted for 46.1% of the assembled genome. We found that the integument development gene INNER NO OUTER (INO) was under positive selection and potentially contributed to the development of the fleshy outer layer of the seed coat, an edible part of pomegranate fruit. The genes encoding the enzymes for synthesis and degradation of lignin, hemicelluloses and cellulose were also differentially expressed between soft- and hard-seeded varieties, reflecting differences in their accumulation in cultivars differing in seed hardness. Candidate genes for punicalagin biosynthesis were identified and their expression patterns indicated that gallic acid synthesis in tissues could follow different biochemical pathways. The genome sequence of pomegranate provides a valuable resource for the dissection of many biological and biochemical traits and also provides important insights for the acceleration of breeding. Elucidation of the biochemical pathway(s) involved in punicalagin biosynthesis could assist breeding efforts to increase production of this bioactive compound. © 2017 The Authors The Plant Journal © 2017 John Wiley & Sons Ltd.

    Herbal drugs are considered alternative agents and have been used for several years around the world. Recurrent aphthous stomatitis (RAS) is one of the most common problems recognized by dentists and skin specialists. This problem is characterized by recurring, painful, small oral mucosal ulcers with a round or oval aspect that mostly appear in keratinized mucosa, cheeks, and on the surface of the mouth under the tongue. In our experiment, the alcoholic and water extracts of Punica granatum var. pleniflora, P. granatum var. Sweet Alak, and P. granatum var. Saveh Black were tested on minor RAS. The study was carried out using the double-blind method. The study population consisted of 210 participants, of whom 69 were females (32%) and 141 were males (68%). In addition to checking several factors, the pain and the degree of the participant's satisfaction had been determined based on visual analog scale. Data analysis was done in the form of a nonparametric method using Kruskal-Wallis test and SPSS version 20 software. The results show that the alcoholic and water extracts of P. granatum var. pleniflora have a meaningful therapeutic effect on minor RAS. Results from the antioxidant activity and its relation to total phenolics show that P. granatum var. pleniflora and P. granatum var. Sweet Alak are rich in phenols. The water and alcoholic extracts of P. granatum varpleniflora decreased the entire time of complete treatment, and the treatment was meaningfully satisfactory for patients who participated in this experiment.

    Global usage of synthetic drugs inadvertently has resulted in deleterious effects and antimicrobial resistance. Phytoextarcts with therapeutic properties appear to be appropriate substitutes for synthetic drugs. Punica granatum (Pomegranate) is a fruit rich in nutraceuticals and therapeutic properties that has lead to its widespread use as folk-medicine for treating innumerable diseases. To determine the in vitro antifungal efficacy of Punica granatum peel extract against the oral Candida compared with clotrimazole. An in vitro study was carried out on 60 saliva samples collected from patients confirmed by clinical and mycological examination as oral candidiasis and subjected to culture on Saborauds Dextrose Agar (SDA) medium and incubated at 37°C for 48 hours. The cultured Candida species were subjected to antifungal susceptibility test by agar well diffusion method. Punica granatum peel extract (Group-I), Ethanol (Group-II Negative control), Clotrimazole (Group-III-Positive control) were inoculated in wells and incubated. Zones of inhibitions were measured with a digital Vernier's callipers and subjected to statistical analysis. ANOVA (analysis of variance) was performed to compare inhibition zones and concentrations of all the three groups. Antifungal efficacy of Punica granatum group and Clotrimazole group were statistically significant with p-value Punica granatum approximated with that of the clotrimazole. The present research was just a venture to usual clinical approach. The results of the study reveal that MIC of peel extract of Punica granatum approximated with that of the clotrimazole. Hence, peel extract of Punica granatum may be used as a substitute for antifungal agents in clinical trials with standardization so as to minimize the deleterious effects for patient compliance.

    With 2-years-old pomegranate (Punica granatum L.) cv. 'Tunisia' cuttings as materials, the growth properties, salt injury indexes, leaf membrane permeability, Chlorophyll (Chl) content, malondialdehyde (MDA) content, proline and soluble protein content, and activities of superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD) were investigated under different NaCl concentrations (0, 0.1, 0.2, 0.3, 0.4, 0.5, and 0.6%, w/w) treatments after 7, 21 and 35 days. The results showed that: the height and ground diameter of pomegranate were increased at low salinity (0.1%), and they were significantly inhibited at high salinity (= 0.5%). With increased NaCl concentrations, Chl a, Chl b, and Chl (a + b) contents were decreased and chlorophyll a/b were increased. Leaf membrane permeability was seriously enhanced and the amount of MDA was markedly increased at high salinity (= 0.5%). The proline and soluble protein were significantly accumulated and quickly responded to NaCl stress. The activities of SOD, CAT, and POD showed a trend of first rising and then decreasing, with the maximum appearing at 0.4% salinity. In addition, the adverse effects on these physiological indexes aggravated gradually over time. Our study suggested that pomegranate 'Tunisi' was a moderately salt tolerant cultivar (0.4% NaCl) with a promoting effect on the growth below 0.1% salinity. This cultivar presents a mechanism of alleviating the detrimental effects of salt stress through improving the proline content, soluble protein content and the activities of antioxidant enzymes. But the protections of antioxidant enzymes are in a limited range of salinity. (author)

    Dental caries is caused by acids produced by biofilm-forming Streptococcus mutans from fermentable carbohydrates and bacterial byproducts. Control of these bacteria is important in the prevention of dental caries. This study investigated the effect of the fruit peel of Punica granatum on biofilm formation, acid and extracellular polysaccharides production (EPS) by S. mutans. Pomegranate fruit peels crude extracts were prepared. The Minimum bactericidal concentrations (MBC) were determined against S. mutans. At 3 sub-bactericidal concentrations, the effect on the acid production, biofilm formation and EPS production was determined. The results were analysed using Kruskal-Wallis and Wilcoxon Rank Sum Tests. The lowest MBC was 6.25 mg/mL. Punica granatum significantly inhibited acid production (p mutans. The crude extract of P. granatum killed cariogenic S. mutans at high concentrations. At sub-bactericidal concentrations, it reduced biofilm formation, acid and EPS production. This suggests that P. granatum extract has the potential to prevent dental caries. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The present study was designed to investigate the ameliorative potential and possible mechanism of hydroalcoholic extract of flowers of P. granatum in glycerol-induced acute renal failure (ARF) in rats. The rats were subjected to rhabdomyolytic ARF by single intramuscular injection of hypertonic glycerol (50% v/v; 8 ml/kg) and the animals were sacrificed after 24 hours of glycerol injection. The plasma creatinine, blood urea nitrogen, creatinine clearance, and histopathological studies were performed to assess the degree of renal injury. Pretreatment with hydroalcoholic extract of flowers of P. granatum (125 and 250 mg/kg p.o. twice daily for 3 days) significantly attenuated hypertonic glycerol-induced renal dysfunction in a dose-dependent manner. BADGE (Bisphenol-A-diglycidyl ether) (30 mg/kg), a peroxisome proliferator-activated receptor (PPAR)-γ antagonist, and N(omega)-nitro-l-arginine-methyl ester (L-NAME) (10, 20, and 40 mg/kg), nitric oxide synthase inhibitor, were employed to explore the mechanism of renoprotective effects of Punica granatum. Administration of BADGE (30 mg/kg) and L-NAME (40 mg/kg) abolished the beneficial effects of P. granatum in glycerol-induced renal dysfunction. Hydroalcoholic extract of flowers of P. granatum has ameliorative potential in attenuating myoglobinuric renal failure and its renoprotective effects involve activation of PPAR-γ and nitric oxide-dependent signaling pathway.

    The pharmacological activities of many Punica granatum L. components suggest a wide range of clinical applications for the prevention and treatment of diseases where chronic inflammation is believed to play an essential etiologic role. The current work reports a case study analyzing the effect produced by a magistral formulation of ethanolic extracts of Punica granatum peels on a non-healing chronic ulcer. The complete closure of the chronic ulcer that was initially not responsive to standard medical care was observed. A 2% (w/w) P. granatum peels ethanolic extract hydrogel-based formulation (PGHF) was standardized and subjected to physicochemical studies to establish the quality control parameters using, among others, assessment criteria such as optimum appearance, pH range, viscosity and hydrogel disintegration. The stability and quantitative chromatographic data was assessed in storage for six months under two temperature regimes. An efficient HPLC-DAD method was established distinguishing the biomarkers punicalin and punicalagin simultaneously in a single 8 min run. PGHF presented suitable sensorial and physicochemical performance, showing that punicalagin was not significantly affected by storage (p > 0.05). Formulations containing extracts with not less than 0.49% (w/w) total punicalagin might find good use in wound healing therapy.

    Glycogen phosphorylase (GP) is a pharmaceutical target for the discovery of new antihyperglycaemic agents. Punica granatum is a well-known plant for its potent antioxidant and antimicrobial activities but so far has not been examined for antihyperglycaemic activity. The aim was to examine the inhibitory potency of eighteen polyphenolic extracts obtained from Punica granatum fruits and industrial juicing byproducts against GP and discover their most bioactive ingredients. Kinetic experiments were conducted to measure the IC50 values of the extracts while affinity crystallography was used to identify the most bioactive ingredient. The inhibitory effect of one of the polyphenolic extracts was also verified ex vivo, in HepG2 cells. All extracts exhibited significant in vitro inhibitory potency (IC50 values in the range of low μg/mL). Affinity crystallography revealed that the most bioactive ingredients of the extracts were chlorogenic and ellagic acids, found bound in the active and the inhibitor site of GP, respectively.While ellagic acid is an established GP inhibitor, the inhibition of chlorogenic acid is reported for the first time. Kinetic analysis indicated that chlorogenic acid is an inhibitor with Ki=2.5 x 10-3Mthat acts synergistically with ellagic acid. Our study provides the first evidence for a potential antidiabetic usage of Punica granatum extracts as antidiabetic food supplements. Although, more in vivo studies have to be performed before these extracts reach the stage of antidiabetic food supplements, our study provides a first positive step towards this process.

    Punica granatum has a recorded history of pharmacological properties which can be attributed to its rich reservoir of phytochemicals. Investigations in recent years have established its tremendous potential as an antitumorogenic agent against various cancers including breast cancer, which is the second leading cause of cancer-related deaths in women. The plausible role of Punica as a therapeutic agent, as an adjuvant in chemotherapy, and its dietary implications as chemopreventive agent in breast cancer have been explored. Mechanistic studies have revealed that Punica extracts and its components, individually or in combination, can modulate and target key proteins and genes involved in breast cancer. Our earlier finding also demonstrated the role of methanolic extract of pomegranate pericarp in reducing proliferation in breast cancer by binding to estrogen receptor at the same time not affecting uterine weight unlike estradiol or tamoxifen. This review analyses other plausible mechanisms of Punica in preventing the progression of breast cancer and how it can possibly be a therapeutic agent by acting at various steps of carcinogenesis including proliferation, invasion, migration, metastasis, angiogenesis, and inflammation via various molecular mechanisms. © 2015 International Union of Biochemistry and Molecular Biology.

    Multiple myeloma is of great concern since existing therapies are unable to cure this clinical condition. Alternative therapeutic approaches are mandatory, and the use of plant extracts is considered interesting. Punica granatum and its derived products were suggested as potential anticancer agents due to the presence of bioactive compounds. Thus, polypenolic-rich extracts of the non-edible parts of P. granatum were investigated for their antiproliferative and apoptotic effects on U266 multiple myeloma cells. We demonstrated that there were dose-dependent decreases in the proliferation of U266 cells in response to P. granatum extracts. Also, exposure to the extracts triggered apoptosis with significant increases in loss of mitochondrial membrane potential in U266 cells exposed to the leaves and stem extracts, while the flower extract resulted in slight increases in loss of MMP. These results were confirmed by Annexin-V analysis. These results documented the cytotoxic and apoptotic effects of P. granatum extracts on human U266 multiple myeloma cells via disruption of mitochondrial membrane potential and increasing cell cycle arrest. The data suggest that the extracts can be envisaged in cancer chemoprevention and call for further exploration into the potential application of these plant parts.

    Pomegranate (Punica granatum L., Punicaceae) is a good source of minerals and phytochemicals with diverse pharmacological activities such as anxiolytic, antidepressant, hypoglycemic, hypolipidemic, and anti-inflammatory activities. Effects of P. granatum on blood parameters and coagulation have, however, been little studied. The aim of the study was to assess the outcome of P. granatum on coagulation and anticoagulation factors at different doses on blood samples of healthy white rabbits. Blood samples of the animals were collected twice during the study and biochemical assays were performed to assess the effect on hematological, coagulation, anticoagulation, and platelet aggregation. Significant changes were observed in erythrocytes, hemoglobin, and mean corpuscular hemoglobin concentration, while bleeding and thrombin time were also prolonged significantly. There was significant increase in protein C, thrombin antithrombin complex levels, and decrease in platelet aggregation and fibrinogen concentration, in a dose-dependent manner. The results of hematological and coagulation assays lead to the speculation about a possible antianemic and cardioprotective effect of P. granatum.

    Cryptosporidiosis, a major health issue for neonatal calves, is caused by the parasite Cryptosporidium parvum, which is highly resistant to drug treatments. To date, many anti-parasitic drugs have been tested, but only a few have been shown to be partially effective in treating cryptosporidiosis. Previous studies have indicated that pomegranate (Punica granatum) possesses anti-plasmodium, anti-cestode, and anti-nematode activities. Therefore, the aim of this study was to evaluate the effect of P. granatum peel on suckling mice infected with experimental C. parvum. At 4days of age, 72 neonatal albino mice were randomly divided into five groups: G1: healthy controls, G2: infected/untreated controls, G3: uninfected/distilled water-treated, G4: uninfected/P. granatum peel-treated, and G5: infected/P. granatum peel-treated. Mice were experimentally-infected by oral administration of 1×10(3)C. parvum oocysts per animal. On day 7 post-inoculation (pi), treated mice received an aqueous suspension of P. granatum peel orally (3g/kg body weight). The presence of diarrhea, oocyst shedding, and weight gain/loss, and the histopathology of ileal sections were examined. Infected mice treated with the P. granatum peel suspension showed improvement in all parameters examined. Additionally, these mice did not exhibit any clinical symptoms and no deaths occurred. Oocyst shedding was very significantly reduced in the P. granatum-treated mice by day 14 pi (Pgranatum-treated mice was significantly higher than that of the infected/untreated controls throughout the study (Pgranatum-treated mice on day 14 pi showed visible improvement in comparison with the infected/untreated controls, including renewed brush borders, reduced numbers of C. parvum trophozoites, and reduced lymphatic infiltration. On day 28 pi, tissues of the P. granatum-treated mice were very similar to those of healthy control mice. These results suggest that P. granatum peel is a promising anti-coccidial therapeutic

    An efficient in vitro propagation is described for Punica granatum L. using shoot tip and nodal explants. The influence of two basal medium, WPM and MS, and different plant growth regulators was investigated on micropropagation of the Iranian pomegranate cultivars, 'Malas Saveh' and 'Yousef Khani'. For proliferation stage, media supplemented with different concentrations (2.3, 4.7, 9.2 and 18.4 μM) of kinetin along with 0.54 μM NAA was used. WPM proved to be more efficient medium compared to MS. The best concentrations of kinetin were 4.7 μM for 'Malas Saveh' and 9.2 μM for 'Yousef Khani', resulting in the highest number of shoots per explants, shoot length and leaf number. For both cultivars, half-strength WPM medium supplemented with 5.4 μM NAA was most effective for rooting of shoots. Rooted plantlets were successfully acclimatized and transferred into soil. The micropropagated plants were morphologically uniform and exhibited similar growth characteristics and vegetative morphology to the mother plants.

    Dietary supplements are becoming more influential as viable treatment for common chronic diseases and to promote normal development and functions of all system including brain. Disorders like anxiety and depression may be managed through healthier variations is dietary pattern, since there are indications that diet rich in antioxidants and vitamins diminish anxiety and depression. Hence this investigation was planned to assess the behavioral effects of Citrus limon and Punica granatum in two combination doses i.e. 0.4 + 5 ml/kg and 0.2 + 8 ml/kg C. limon and P. granatum respectively in rats. Antidepressant and anxiolytic effects were explicitly judged twice during 15 days using forced swimming and open field tests and elevated plus maze. In open field test C. limon and P. granatum showed increase in distance travelled, number of central entries and number of rearing's at 0.4 + 5 ml/kg combination, in the elevated plus maze, number of open arm entries were found to be augmented and in forced swimming test, there was decline in duration of immobility and rise in duration of climbing at both combinations i.e. 0.4 + 5 ml/kg and 0.2 + 8 ml/kg C. limon and P. granatum. These results suggest that C. limon and P. granatum at 0.4 + 5 ml/kg combination have anxiolytic and antidepressant effect.

    Full Text Available Human and veterinary medicines have not been so well succeeded in order to achieving their goals concerning the treatment of infections for long term caused by Staphylococcus aureus linked to resistance development against antibiotic agents. The antibiotic activity of the Punica granatum Linn. fresh fruit pericarp extract was evaluated by the agar diffusion method on 38 S. aureus strains, isolated from apparently healthy lactating cows in farms situated in counties of the semi-arid region of the State of Paraíba, Brazil to determine the minimum inhibitory concentration (MIC. Twenty-two of the thirty-eight strains are penicillin-resistant (PRSA. The extract of P. granatum presented potential antibiotic action over all the assayed strains, forming 10 to 36 mm diameter inhibition zones. This paper's results claim the effectiveness of the extract of P. granatum as a potential antibacterial agent on S. aureus, and display the significance of evaluating new substances with antimicrobial potential, which can contribute to alternative therapeutics for veterinary and medicine.

    The aim of the present study was to enhance the biosorption capacity of a waste biomass of Punica granatum L. peels (PGL) using various chemical modification agents. Among these agents, hexamethylenediamine (HMDA) indicated the best performance with regard to the improvement of lead(II) ions removal from aqueous solution. The characterization of HMDA-modified P. granatum L. peels (HMDA-PGL) was achieved by using elemental analysis, FT-IR, thermogravimetric (TG) analysis and zeta potential measurement techniques. Based on FT-IR study, the chemical modification of P. granatum L. peels take place with its carboxyl, carbonyl, hydroxyl, etc. groups and these groups are responsible for the biosorption of lead(II) ions onto modified biomass. Biosorption equilibrium and kinetic data fitted well the Langmuir isotherm and the pseudo-second-order kinetic models, respectively. The highest biosorption capacity obtained from Langmuir isotherm model was 371.36 mg g -1 . Biosorption process was spontaneous and endothermic in nature according to the thermodynamic results and it quickly reached the equilibrium within 60 minutes. The validity of kinetic models used in this study can be quantitatively tested by using a normalized standard deviation Δq(%).

    Full Text Available The objective of this study was to investigate the effect of crude extracts of Punica granatum Linn. pericarp with 3 different solvents against pathogenic Gram-negative bacilli. Ethanolic extracts showed the antibacterial activity against all strains tested including enterohaemorrhagic Escherichia coli 4 strains (E. coli O157: H7, E. coli O26: H11, E. coli O111: NM, E. coli O22, Pseudomonas aeruginosa, Shigella boydii and Salmonella london. Inhibition zones ranged from 10.02 to 19.15 mm. Minimum inhibitory concentration (MIC and minimum bactericidal concentration (MBC ranged from 0.09 to 3.13 mg/ml and 3.13 to 25 mg/ml, respectively. Aqueous extract had low antibacterial activity while crude chloroform extracts had no effect on the growth of these strains. Ethyl acetate and n-butanol fractions of P. granatum pericarp demonstrated high activity with the best MIC and MBC values of 0.02 to 0.78 mg/ml and 0.19 to 6.25 mg/ml, respectively. As ethanolic extract of P. granatum was very effective against these pathogenic bacteria, further investigation on this plant species may provide alternative, but bioactive, medicines for the treatment of Gram-negative bacterial infection.

    Punica granatum L. var. granatum (Pomegranate), an herbaceous plant found in Iran, The aim of this study was to investigate the cytotoxic effects, induction of apoptosis, and the mechanism of cell death of ethanol extract from Punica granatum L. var. spinosa on the mouse fibrosarcoma cell line, WEHI-164. Various parts of the herbs were extracted from fruit using ethanol as the solvent, and the cytotoxicity and cell viability of the ethanolic extract were determined by the MTT assay. To determine whether necrosis or apoptosis is the predominant cause of cell death, cell death detection was performed using the ELISA method. The induction of apoptosis was confirmed using the terminal deoxynucleotidyl transferase- (TdT-) mediated dUTP nick end labeling (TUNEL) assay. Moreover, a sensitive immunoblotting technique was used to examine the production of Caspase-3 and Bcl2 proteins. Our findings suggested that the ethalonic extract of Punica granatum L. var. spinosa altered cell morphology, decreased cell viability, suppressed cell proliferation and induced cell death in a time- and dose-dependent manner in WEHI-164 cells (IC50 = 229.024μg/ml), when compared to a chemotherapeutic anticancer drug, Toxol (Vesper Pharmaceuticals), with increased nucleosome production from apoptotic cells. Induction of apoptosis by the plant extract was proved by the decrease of pro-Caspase-3 and Bcl2 proteins and quantitatively confirmed by Immunoblotting analysis. The results obtained from the present study have demonstrated the growth-inhibitory effect of Ethanol Extracts from Punica granatum L. var. spinosa, and clearly showed that apoptosis was the major mechanism of in-vitro cell death induced by the extract.

    Engineered scaffolds made from natural biomaterials are crucial elements in tissue engineering strategies. In this study, biological scaffold like chitosan-collagen-starch membrane (CCSM) loaded with the antibacterial agent, Punica granatum pericarp aqueous extract was explored for enhanced regeneration of epithelial tissue during wound healing. Collagen was extracted from Rachycentron canadum fish skin. Membranous scaffold was prepared by mixing collagen, starch and chitosan in a fixed proportion, loaded with aqueous extract of P. granatum and its anti-pseudomonal activity was studied. Morphological characterization by SEM and mechanical property like tensile strength of the membrane were studied. Excision wound of 2 cm(2) size was induced in Guinea pig and the effect of P. granatum extract loaded CCSM in wound healing was studied. The SEM image showed deep pores in the membrane and also possessed good tensile strength. Wound surface area was reduced prominently in the experimental group with P. granatum extract loaded CCSM when compared to the group with unloaded membrane and the one with no membrane. Punica granatum extract loaded CCSM has antipseudomonal property and supported enhanced epithelial cell proliferation without leaving a scar after wound healing. This has significant therapeutic application in membranous scaffold mediated skin repair and regeneration.

    The Punica granatum L. var. granatum (pomegranate) has been demonstrated to exert antitumor effects on various types of cancer cells. The present study aimed to evaluate the medicinal herbs Punica granatum L. var. spinosa (apple punice) that are native to Iran. This study was determined to test the possible cytotoxic activity and induction of apoptosis on human prostate cell lines. The effect of ethanol extracts of the herbs on the inhibition of cell proliferation was assessed by MTT colorimetric assay. PC3 cell lines treated with the extracts were analyzed for the induction of apoptosis by cell death detection (ELISA) and TUNEL assay. Dye exclusion analysis was performed for viability rate. Our results demonstrated that the Punica granatum L. var. spinosa extract dose dependently suppressed the proliferation of PC3 cells (IC(50)= 250.21 μg/mL) when compared with a chemotherapeutic anticancer drug (Toxol) (Vesper Pharmaceuticals) with increased nucleosome production from apoptotic cells. The Punica granatum L. var. spinosa extract attenuated the human prostate cell proliferation in vitro possibly by inducing apoptosis. The Punica granatum L. var. spinosa is likely to be valuable for the treatment of some forms of human prostate cell line.

    Pomegranate (Punica granatum L.) has been used for centuries for the treatment of inflammatory diseases. However, there is a lack of comprehensive information focused on the properties of a certain pomegranate (poly)phenolic profile to cure pain and gastric injury induced by anti-inflammatory drugs. This study investigated the systemic effects of different doses of a HPLC-characterized pomegranate extract on the formalin-induced nociceptive behavior in mice. The effect of the extract against gastric injury caused by non-steroidal anti-inflammatory drugs and ethanol was also assessed. Pomegranate reduced nociception in both phases of the formalin test, suggesting central and peripheral activities to inhibit nociception. Indomethacin-induced gastric injury was not produced in the presence of pomegranate, which also protected against ethanol-induced gastric lesions. The present results reinforce the benefits of pomegranate (poly)phenolics in the treatment of pain as well as their anti-inflammatory properties.

    Punica granatum juice, a delicious multivitamin drink of great medicinal significance, is rich in different types of phytochemicals, such as terpenoids, alkaloids, sterols, polyphenols, sugars, fatty acids, aromatic compounds, amino acids, tocopherols, etc. We have demonstrated the use of the juice for the synthesis of gold nanoparticles (AuNPs) at room temperature under very mild conditions. The synthesis of the AuNPs was complete in few minutes and no extra stabilizing or capping agents were necessary. The size of the nanoparticles could be controlled by varying the concentration of the fruit extract. The AuNPs were characterized by surface plasmon resonance spectroscopy, high resolution transmission electron microscopy, fourier transform infrared spectroscopy and X-ray diffraction studies. Catalytic activity of the synthesized colloidal AuNPs has also been demonstrated.

    This study evaluated the in vitro antibacterial effects of the formulated Punica granatum (PG) gel against Streptococcus mutans, Streptococcus sanguinis, and Lactobacillus casei. The PG extract was dissolved in water at 500 mg/mL. High performance liquid chromatography (HPLC) was used for identification and quantification of chemical marker punicalagin. Minimum bactericidal concentration (MBC) and time-kill assay (TKA) were investigated. Antibacterial activities of the formulated PG gel, 2% chlorhexidine (CHX) gel and blank gel were tested by measuring the zones of inhibition through agar well diffusion method. The HPLC results showed presence of punicalagin at 2023.58 ± 25.29 pg/mL in the aqueous PG extract and at 0.234% (w/w) in the formulated PG gel. The MBC for S. mutans, S. Sanguinis, and L. casei were 250, 125, and 500 mg/mL respectively. The TKA of 500 mg/mL aqueous PG extract showed total inhibition of S. mutans, S. Sanguinis, and L. casei at 6, 1, and 24 hours contact time respectively. Agar well diffusion revealed that for S. mutans, CHX gel > PG gel > blank gel; for S. sanguinis, CHX gel = PG gel > blank gel; for L. casei, CHX gel > PG gel = blank gel. Comparison of the PG gel potency showed that S. sanguinis = S. mutans > L. casei. The PG gel equivalent to 0.234% punicalagin (w/w) inhibited S. mutans and S. sanguinis but not L. casei within 24 hours incubation period and has the potential to be used for caries prevention.

    Punica granatum has a noticeable adaptation to drought stress. The levels of the green leaf volatile trans-2-hexenal increased in response to drought stress suggesting a possible role of this compound in drought stress response in pomegranate. Punica granatum (L.) is a highly valued fruit crop for its health-promoting effects and it is mainly cultivated in semi-arid areas. Thus, understanding the response mechanisms to drought stress is of great importance. In the present research, a metabolomics analysis was performed to evaluate the effects of drought stress on volatile organic compounds extracted from the leaves of pomegranate plants grown under water shortage conditions. The time course experiment (7 days of water deprivation and 24-h recovery) consisted of three treatments (control, drought stress, and rehydration of drought-stressed plants). Plant weights were recorded and control plants were irrigated daily at pot capacity to provide the lost water. Fraction of transpirable soil water has been evaluated as indicator of soil water availability in stressed plants. The levels of proline, hydrogen peroxide and lipid peroxidation as well as of the photosynthetic parameters such as photosynthesis rate (A), stomatal conductance (g s), photosynthetic efficiency of photosystem II, and photochemical quenching were monitored after the imposition of drought stress and recovery as markers of plant stress. Constitutive carbon volatile components were analyzed in the leaf of control and drought-stressed leaves using Head Space Solid Phase Micro Extraction sampling coupled with Gas Chromatography Mass Spectrometry. A total of 12 volatile compounds were found in pomegranate leaf profiles, mainly aldehydes, alcohols, and organic acids. Among them, the trans-2-hexenal showed a significant increase in water-stressed and recovered leaves respect to the well-watered ones. These data evidence a possible role of the oxylipin pathway in the response to water stress in pomegranate

    Full Text Available Punica granatum L. has a long standing culinary and medicinal traditional use in Mauritius. This prompted a comparative study to determine the bioefficacy of the flower, peel, leaf, stem, and seed extracts of the Mauritian P. granatum. The flower and peel extracts resulting from organic solvent extraction exhibited strong antioxidant activities which correlated with the high levels of total phenolics, flavonoids, and proanthocyanidins. The peel extract had the most potent scavenging capacity reflected by high Trolox equivalent antioxidant capacity value ( μmol/g air dry weight, very low IC50 values for hypochlorous acid ( mg air dry weight/mL, and hydroxyl radicals scavenging ( mg air dry weight/mL. Peel extracts also significantly inhibited S. mutans (, S. mitis (, and L. acidophilus ( growth compared to ciprofloxacin. The flower extract exhibited high ferric reducing, nitric oxide scavenging, and iron (II ions chelation and significantly inhibited microsomal lipid peroxidation. Furthermore, it showed a dose-dependent inhibition of xanthine oxidase with an IC50 value of  mg air dry weight/mL. This study showed that nonedible parts of cultivated pomegranates, that are generally discarded, are bioactive in multiassay systems thereby suggesting their potential use as natural prophylactics and in food applications.

    Full Text Available Leishmania species are parasites that multiply within phagocytes and cause several clinical diseases characterized by single or multiple ulcerations. One of the complications that can induce tissue damage and the resulting scars is caused by secondary bacterial infections. Studies to find new, effective, and safe oral drugs for treating leishmaniasis are being conducted since several decades, owing to the problems associated with the use of antimonials available. Previously, the antiparasitic and antioxidant properties of Punica granatum (pomegranate, P. granatum have been reported. Therefore, in the present study, we aimed to investigate the antileishmanial activity of pomegranate aqueous juice in vitro and in female BALB/c mice. A 3-(4.5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide (MTT assay in Leishmania major promastigotes and alterations in the antioxidant status, liver function, and skin histological changes in L. major-infected mice orally treated with pomegranate juice alone and in combination with the antibiotic ciprofloxacin, were used to investigate the in vitro and in vivo antileishmanial activity of pomegranate juice, respectively. Oral P. granatum juice treatment significantly reduced the average size of cutaneous leishmaniasis lesions compared with that of the untreated mice. This antileishmanial activity of P. granatum was associated with enhanced antioxidant enzyme activities. Histopathological evaluation proved the antileishmanial activity of P. granatum, but did not reveal changes in the treated animals, compared to the positive control. In conclusion, P. granatum shows high and fast antileishmanial activity probably by boosting the endogenous antioxidant activity.

    Full Text Available With an objective to develop Complementary and Alternative Medicine for the treatment of diabetic nephropathy, the present study investigated the protective effects of methanolic extract of Punica granatum leaves (MPGL in streptozotocin-induced diabetic nephropathy. Diabetic nephropathy has become a leading cause of end stage renal failure worldwide. P. granatum, due to its anti-diabetic, anti-inflammatory and antioxidant activities may retard the progression of diabetic nephropathy. In this study, diabetes was induced by a single injection of streptozotocin (STZ, 45 mg/kg, i.p. in rats. STZ-diabetic rats were treated with oral doses of MPGL (100, 200 and 400 mg/kg for 8 weeks. At the end of the experimental period, body and kidney weight and blood glucose levels were determined. Serum and urine parameters were investigated. Antioxidant enzymes and lipid peroxide levels were determined in the kidney along with histopathological examination of the same. MPGL significantly increased body weight, lowered blood glucose levels and ameliorated kidney hypertrophy index in the STZ-diabetic rats. The extract also decreased the levels of creatinine, blood urea nitrogen, total cholesterol, triglycerides, advanced glycation end products and albumin in serum and urine, respectively. MPGL significantly increased the antioxidant parameters in the kidney. Histological evaluation revealed that MPGL treated STZ-diabetic rats demonstrated reduced vacuolar degeneration of tubules; periodic acid Schiff base (PAS positivity staining intensity in glomeruli and basement membrane thickening. Present findings provide experimental evidence that MPGL has potential antioxidant, antihyperglycemic and anti-glycation activities which might be helpful in slowing the progression of diabetic nephropathy.

    Various morphological parts of pomegranate (Punica granatum L.) have extensively been used in the folk medicine to treat an array of human ailments. The aim of the present study is to demonstrate the anticonvulsant potential of the ethanolic extract of P. granatum L. seed in chemoconvulsant-induced seizures in mice. The anticonvulsant activity of the ethanolic extract was investigated in strychnine (STR)-induced and pentylenetetrazole (PTZ)-induced seizure models in mice. Diazepam was used as reference anticonvulsant drug. Ethanolic extract (150, 300, and 600 mg/kg per os, p.o.), diazepam (1 mg/kg intraperitoneally, i.p.), and distilled water (10 ml/kg, i.p.) were administered before induction of seizures by PTZ (60 mg/kg, i.p.) or STR (2.5 mg/kg, i.p.). The latent time before the onset of convulsions, the duration of convulsions, the percentage of seizure protection, and mortality rate were recorded. The seed ethanolic extract did not show any toxicity and did not protect the animals against seizures but demonstrated a significant increase in seizure latency at 300 and 600 mg/kg in both STR and PTZ seizure models (P < 0.001). It also showed a significant reduction in seizure duration at 300 mg/kg (P < 0.05) and 600 mg/kg (P < 0.001) in the STR seizure model and 600 mg/kg (P < 0.01) in the PTZ seizure model compared with the control group. Ethanol extract has dose-dependent anticonvulsant activity against STR- and PTZ-induced seizures. This activity might be due to its saponins, flavonoids, triterpenes, and alkaloids ingredients.

Using bioinformatics annotation libraries, a total of 76,806 unigenes were annotated and, among the high-quality reads, 72.63% had at least one significant match to an existing gene model. Gene expression and differentially expressed genes were analyzed. The seed formation of the two pomegranate cultivars involves lignin biosynthesis and metabolism, including some genes encoding laccase and peroxidase, WRKY, MYB, and NAC transcription factors. In the hard-seed pomegranate, lignin-related genes and cellulose synthesis-related genes were highly expressed; in soft-seed pomegranates, expression of genes related to flavonoids and programmed cell death was slightly higher. We validated selection of the identified genes using qRT-PCR. This is the first transcriptome analysis of P. granatum L. This transcription sequencing greatly enriched the pomegranate molecular database, and the high-quality SSRs generated in this study will aid the gene cloning from pomegranate in the future.

    Radiation-induced enteritis is a well-recognized sequel of therapeutic irradiation. Therefore we examined the radioprotective properties of Punica granatum peel extract (PPE) on the oxidative damage in the ileum. Rats were exposed to a single whole-body X-ray irradiation of 800 cGy. Irradiated rats were pretreated orally with saline or PPE (50 mg/kg/day) for 10 days before irradiation and the following 10 days, while control rats received saline or PPE but no irradiation. Then plasma and ileum samples were obtained. Irradiation caused a decrease in glutathione and total antioxidant capacity, which was accompanied by increases in malondialdehyde levels, myeloperoxidase activity, collagen content of the tissue with a concomitant increase 8-hydroxy-2'-deoxyguanosine (an index of oxidative DNA damage). Similarly, pro-inflammatory cytokines (TNF-α, IL-1β and IL-6) and lactate dehydrogenase were elevated in irradiated groups as compared to control. PPE treatment reversed all these biochemical indices, as well as histopathological alterations induced by irradiation. Furthermore, flow cytometric measurements revealed that leukocyte apoptosis and cell death were increased in irradiated animals, while PPE reversed these effects. PPE supplementation reduced oxidative damage in the ileal tissues, probably by a mechanism that is associated with the decreased production of reactive oxygen metabolites and enhancement of antioxidant mechanisms. Adjuvant therapy of PPE may have a potential to support a successful radiotherapy by protecting against radiation-induced enteritis. (author)

    Having served as a symbolic fruit since ancient times, pomegranate ( Punica granatum ) has also gained considerable recognition as a functional food in the modern era. A large body of literature has linked pomegranate polyphenols, particularly anthocyanins (ATs) and hydrolyzable tannins (HTs), to the health-promoting activities of pomegranate juice and fruit extracts. However, it remains unclear as to how, and to what extent, the numerous phytochemicals in pomegranate may interact and exert cooperative activities in humans. In this review, we examine the structural and analytical information of the diverse phytochemicals that have been identified in different pomegranate tissues, to establish a knowledge base for characterization of metabolite profiles, discovery of novel phytochemicals, and investigation of phytochemical interactions in pomegranate. We also assess recent findings on the function and molecular mechanism of ATs as well as urolithins, the intestinal microbial derivatives of pomegranate HTs, on human nutrition and health. A better understanding of the structural diversity of pomegranate phytochemicals as well as their bioconversions and bioactivities in humans will facilitate the interrogation of their synergistic/antagonistic interactions and accelerate their applications in dietary-based cancer chemoprevention and treatment in the future.

    Full Text Available This study investigated the chemoprotective effects of Punica granatum L. (Punicaceae fruits alcoholic extract (PGE on mice exposed to hexavalent chromium [Cr(VI]. Animals were pretreated with PGE (25, 50 or 75 mg/kg/day for 10 days and subsequently exposed to a sub-lethal dose of Cr(VI (30 mg/kg. The frequency of micronucleated polychromatic erythrocytes in the bone marrow was investigated and the Cr(VI levels were measured in the kidneys, liver and plasm. For the survival analysis, mice were previously treated with PGE for 10 days and exposed to a single lethal dose of Cr(VI (50 mg/kg. Exposure to a sub-lethal dose of Cr(VI induced a significant increase in the frequency of micronucleated cells. However, the prophylactic treatment with PGE led to a reduction of 44.5% (25 mg/kg, 86.3% (50 mg/kg and 64.2% (75 mg/kg in the incidence of micronuclei. In addition, the 50 mg/kg dose of PGE produced a higher chemoprotective effect, since the survival rate was 90%, when compared to that of the non-treated group. In these animals, reduced amounts of chromium were detected in the biological materials, in comparison with the other groups. Taken together, the results demonstrated that PGE exerts a protective effect against Cr(VI-induced genotoxicity.

    The hydroalcoholic extract of Punica granatum (pomegranate) leaves was previously demonstrated to be anti-inflammatory in a rat model of lipopolysaccharide- (LPS-) induced acute peritonitis. Here, we investigated the anti-inflammatory effects of the ethyl acetate fraction obtained from the pomegranate leaf hydroalcoholic extract (EAFPg) on the LPS-induced acute lung injury (ALI) mouse model. Male Swiss mice received either EAFPg at different doses or dexamethasone (per os) prior to LPS intranasal instillation. Vehicle-treated mice were used as controls. Animals were culled at 4 h after LPS challenge, and the bronchoalveolar lavage fluid (BALF) and lung samples were collected for analysis. EAFPg and kaempferol effects on NO and cytokine production by LPS-stimulated RAW 264.7 macrophages were also investigated. Pretreatment with EAFPg (100–300 mg/kg) markedly reduced cell accumulation (specially neutrophils) and collagen deposition in the lungs of ALI mice. The same animals presented with reduced lung and BALF TNF-α and IL-1β expression in comparison with vehicle controls (p < 0.05). Additionally, incubation with either EAFPg or kaempferol (100 μg/ml) reduced NO production and cytokine gene expression in cultured LPS-treated RAW 264.7 macrophages. Overall, these results demonstrate that the prophylactic treatment with EAFPg attenuates acute lung inflammation. We suggest this fraction may be useful in treating ALI. PMID:29675437

    Full Text Available Antibacterial, anti-inflammatory and antiparasitic properties have been associated with the extract of pomegranate (Punica granatum in several animals and conditions. The Japanese quail (Coturnix japonica, originated from North Africa, Europe and Asia, is used worldwide as an experimental animal and model for aviculture. The current study investigated the effects of the pomegranate pericarp aqueous extract on the shedding, viability and morphometry of three Eimeria spp. from Japanese quails, besides the weight gain and genotoxic activity. Although the pomegranate is recognized by multiple properties, including anti-coccidial, in the current study the results are contrary. The treated group shed greater amount of oocysts; the sporulation times and viability were similar in both groups; despite some morphometric differences, these were not expressive; weight gains were similar; and the pomegranate had insignificant effect genotoxic. Finally, these results suggest that the pomegranate pericarp extract did not influence on Eimeira spp. from Japanese quails; therefore, the pomegranate pericarp extract is not suggested in the prevention/treatment of coccidiosis in Japanese quails, or at least not using methods of preparation and administration applied in this study.

    Pomegranate (Punica granatum) has been traditionally used as medicine in many countries due to its high antioxidant activity, which has been related to beneficial health properties. Aspartame (ASP) is a widely used artificial sweetener that may be harmful at abuse levels. The objective of this study was to evaluate the potential efficacy of pomegranate juice (PJ) in protecting tissues from the possible damage induced by aspartame. ASP treated rats were given ASP, by gavages, at a dose of 250 mg/kg /day for 28 days. PJ-ASP treated rats were given PI at a dose of 1ml /kg body weight/day along with ASP. The data obtained indicate that ASP administration results in no significant change in the concentration of serum triglycerides (TG), total cholesterol (Tc), low-density lipoprotein (LDL-c), high density lipoprotein (HDL-c) and glucose while significant decreases have been recorded for insulin. The results demonstrated also that aspartame promotes lipid peroxidation and decreases the level of antioxidants superoxide dismutase (SOD) and catalase (Cat) activities and reduced glutathione (GSH) contents in serum and liver tissues. Significant elevations in the activities of serum aspartate transaminase (AST), serum alanine transaminase (AL T) and alkaline phosphatase (ALP) were also observed. Administration of PI in parallel with aspartame protected rats from aspartame-induced oxidative injury and ameliorated liver function

  17. EXTRACT OF Punica granatum L.: AN ALTERNATIVE TO BHT AS AN ANTIOXIDANT IN SEMISSOLID EMULSIFIED SYSTEMS

    Jéssica Tiago Tozetto

    Full Text Available Pomegranate (Punica granatum L. is a fruit which has important pharmacological activities and has been attracting attention due to its important antioxidant activity, a significant feature in relation to cosmetics. Formulations containing different concentrations of an ethanolic extract of pomegranate (0.1, 1.0 and 5.0% (w/w as an antioxidant agent showed that this is an interesting alternative for the use of natural products with biological activity. The stability and rheology of semissolid systems containing an extract of this plant were evaluated. Preliminary stability studies showed greater physico-chemical stability of the formulation, and thus it was used in an accelerated stability study, as well the quantification of total phenolic compounds and the determination of antioxidant activity. It was observed that different concentrations of the extract did not significantly influence the stability. Moreover, the formulation was found to have better stability when stored at room temperature than under heated or cooled conditions. Formulations containing 0.1 and 5.0% of extract showed more stable rheological behavior, due to the absence of a solid/liquid transition in the rheogram. Tests confirmed the high phenolic content and antioxidant activity, demonstrating the potential of this plant for use in cosmetology as an antioxidant.

    Galactomannan (PSP001) isolated from the fruit rind of Punica granatum was demonstrated as an excellent antioxidant, immunomodulatory and anticancer agent both in vitro and in vivo models. Since the most lethal and debilitating attribute of cancer cells is their ability to evolve to a state of malignancy, with key features like increased angiogenesis, invasion, migration, colony formation, and metastasis, the present study focused on evaluating the effects of the galactomannan on tumor and malignancy. PSP001 effectively reduced the neovascularization in chick embryos highlighting its potential as an angiogenic inhibitor. Furthermore, the invasion, migration and clonogenic capacity of human and murine cancer cells were dramatically inhibited by PSP001. Evaluation of the molecular mechanism of its unique potential revealed the down regulation of key players including VEGF, MMP-2, and MMP-9 with marked elevation of TIMP-1 and TIMP-2. The anti-metastatic potential of PSP001 tested in pulmonary metastasis C57BL/6 mice model deciphered the combinatorial administration with vincristine deliberated better survival rates and decreased metastatic index. The angiogenic inhibition potential of PSP001 was further proved with peritoneal angiogenesis assay in BALB/c mice ascitic tumor model. The outcomes of the current investigation highlight the mode of action of antitumor galactomannan in the reduction of tumor malignancy. Copyright © 2017. Published by Elsevier B.V.

    Full Text Available Many herbal medicines have been recommended for the treatment of dyslipidemia. The antilipidemic effect of hydroethanolic extract of pomegranate peel (Punica granatum L. was investigated in high lipid diet fed male rats. Intraperitoneally administration of pomegranate peel extract (50, 100, 200, and 300 mg/kg body weight for 23 days on the levels of serum cholesterol, triglycerides, LDL, HDL, alkaline phosphatase (AP, aspartate aminotransferase (AST, and alanine aminotransferase (ALT in high lipid diet fed male rats was evaluated. Treatment of pomegranate extract decreased body weight in treated rats, significantly. Administration of the plant extract significantly decreased serum total cholesterol, triglycerides, LDL-C, alkaline phosphatise, AST, and ALT levels, whereas it increased serum HDL-C in high lipid diet fed rats in comparison to saline control group. Also, histopathological study showed that treatment of pomegranate peel extract attenuates liver damage in high lipid diet fed rats in comparison to saline group. It is concluded that the plant should be considered as an excellent candidate for future studies on dyslipidemia.

    This study characterises the genetic variability of local pomegranate ( Punica granatum L.) germplasm from the Slovenian and Croatian areas of Istria. The bioactive components and antioxidant and antimicrobial properties of ethanol and water extracts of different parts of pomegranate fruit were also determined, along with their preliminary nutritional characterisation. Twenty-six different genotypes identified with microsatellite analysis indicate the great diversity of pomegranate in Istria. The pomegranate fruit ethanol extracts represent rich sources of phenolic compounds (mean value of the mass fraction in exocarp and mesocarp expressed as gallic acid is 23 and 16 mg/g, respectively). The ethanol extracts of pomegranate exocarp and mesocarp showed the greatest antimicrobial activity against Candida albicans , Candida parapsilosis , Rhodotorula mucilaginosa , Exophiala dermatitidis and Staphylococcus aureus , and the same water extracts against S. aureus and Escherichia coli. To the best of our knowledge, this study represents the first report of the characterisation of pomegranate genetic resources from Istria at different levels, including the molecular, chemical, antimicrobial and nutritional properties.

    Punica granatum (Pg), commonly known as pomegranate (Pg), is a member of the monogeneric family, Punicaceae, and is mainly found in Iran which is considered to be its primary centre of origin. Pg and its chemical components possess various pharmacological and toxicological properties including antioxidant, anti-inflammatory (by inhibiting pro-inflammatory cytokines), anti-cancer and anti-angiogenesis activities. They also show inhibitory effects on invasion/motility, cell cycle, apoptosis, and vital enzymes such as cyclooxygenase (COX), lipooxygenase (LOX), cytochrome P450 (CYP450), phospholipase A2 (PLA2), ornithine decarboxylase (ODC), carbonic anhydrase (CA), 17beta-hydroxysteroid dehydrogenase (17β-HSDs) and serine protease (SP). Furthermore, they can stimulate cell differentiation and possess anti-mutagenic effects. Pg can also interfere with several signaling pathways including PI3K/AKT, mTOR, PI3K, Bcl-X, Bax, Bad, MAPK, ERK1/2, P38, JNK, and caspase. However, the exact mechanisms for its pharmacological and toxicological properties remain to be unclear and need further evaluation. These properties strongly suggest a wide range use of Pg for clinical applications. This review will discuss the areas for which Pg has shown therapeutic properties in different mechanisms.

    Pomegranate (Punica granatum L.) has an ancient cultivation history and has become an emerging profitable fruit crop due to its attractive features such as the bright red appearance and the high abundance of medicinally valuable ellagitannin-based compounds in its peel and aril. However, the limited genomic resources have restricted further elucidation of genetics and evolution of these interesting traits. Here, we report a 274-Mb high-quality draft pomegranate genome sequence, which covers approximately 81.5% of the estimated 336-Mb genome, consists of 2177 scaffolds with an N50 size of 1.7 Mb and contains 30 903 genes. Phylogenomic analysis supported that pomegranate belongs to the Lythraceae family rather than the monogeneric Punicaceae family, and comparative analyses showed that pomegranate and Eucalyptus grandis share the paleotetraploidy event. Integrated genomic and transcriptomic analyses provided insights into the molecular mechanisms underlying the biosynthesis of ellagitannin-based compounds, the colour formation in both peels and arils during pomegranate fruit development, and the unique ovule development processes that are characteristic of pomegranate. This genome sequence provides an important resource to expand our understanding of some unique biological processes and to facilitate both comparative biology studies and crop breeding. © 2017 The Authors.

    Galactomannan polysaccharide (PSP001) was isolated from the fruit rind of Punica granatum and was previously reported to have excellent antioxidant and immunomodulatory properties. The cytotoxicity of PSP001 was evaluated in the human cancer cell lines A375, HCT116, and HepG2 as well as the murine cancer cell lines DLA and EAC over a wide range of concentrations. PSP001 exhibited significant cytotoxicity against cancer cells through the induction of apoptosis with no in vivo toxicity up to a concentration of 2000 mg/kg body weight when assessed in BALB/c mice. The antitumor efficacy of PSP001 was tested in DLA and EAC murine ascites and EAC solid tumor mouse models. PSP001 alone and in combination with doxorubicin produced a significant reduction in the tumor burden and increased life span in both models compared to the controls. The results suggest that PSP001 has the potential to be developed as an anticancer agent either alone or as an adjuvant to chemotherapy. Copyright © 2013 Elsevier Ltd. All rights reserved.

    The α-glucosidase and maltase inhibitory effects of Punica granatum L. flowers (PGF) were investigated. The methanol extract (PGFMe), n-hexane extract (PGFH), chloroform extract (PGFC) and the remaining water fraction (PGFW) were assayed for their α-glucosidase and maltase inhibitory effects. PGFW showed potent α-glucosidase inhibition with IC₅₀ of 0.8 μg/mL followed by PGFMe (IC₅₀ of 4.0 μg/mL) then PGFC (IC₅₀ of 5.21 μg/mL) in comparison to acarbose (0.9 μM). Due to its selectivity towards α-glucosidase, PGFC was subjected to bioactivity-guided isolation of its main active constituents. Five known compounds (1-5) were identified as β-sitosterol (1), oleanolic acid (2), ursolic acid (3), p-coumaric acid (4) and apigenin (5). Ursolic and oleanolic acids showed potent α-glucosidase inhibition (IC₅₀ of 39.0 and 35.0 μM, respectively), while they did not show significant maltase inhibition. Kinetic study using the double Lineweaver-Burk plot revealed that ursolic acid uncompetitively inhibited α-glucosidase in comparison with acarbose as a competitive inhibitor.

    Objective: To compare the antihyperlipidemic effects of Eugenia Jambolana fruit pulp with Punica Granatum fruit in diet induced hyperlipidaemic rats at the same dose level. Methods: An experimental randomized control study was conducted on seventy five male albino rats over a period of 14 weeks in University of Health Sciences Lahore. They were divided into five groups labelled A, B, C, D and E with fifteen rats in each group. Group A was kept as normal control, groups B, C, D and E were given hyperlipidaemic diet for six weeks. In group B no further intervention was done, group C and D were given ethanolic extract of Eugenia Jambolana and Punica Granatum respectively for eight weeks. Group E was given combination of both for same duration. Serum total cholesterol (TC), high density lipoprotein cholesterol (HDL-c), lowdensity lipoprotein cholesterol (LDL-c) and triglycerides (TG) were measured at zero, six and fourteen weeks. Results: At fourteenth week significant reductions in TC, LDL-c and TG and a rise in HDL-c was observed in interventional groups C, D and E as compared to experimental hyperlipidaemic control group B (p 0.57, p > 0.22, p > 0.56, p > 0.76, respectively. On sixth week, there was no significant difference between groups B, C, D and E (p > 0.05). However, 15 rats of group A had significant lower levels of cholesterol, high density lipoproteins, low density lipoproteins and triglycerides when compared to 60 rats of groups B, C, D and E (p<0.05). Conclusion: In male albino rats combination of ethanolic extracts of Eugenia Jambolana and Punica Granatum fruit pulps was most effective in lowering serum total cholesterol and triglycerides while decrease in low density lipoprotein cholesterol and rise in high density lipoprotein cholesterol was same as the extracts given alone.

    Ionizing radiation generates reactive oxygen species (ROS) in irradiated tissue. Cells of liver have their own defence system, the antioxidant system to deactivate ROS. Antioxidant system includes enzymatic and non-enzymatic components. Liver is rich in endogenous antioxidants and related enzymes. Catalase and Superoxide dismutase (SOD) are powerful antioxidant enzymes. In the present study Punica granatum fruit rind Ethanol extract (PGFRE) was tested against 60 Co gamma radiation induced alteration in Swiss albino mouse. Healthy adult (25±2) Swiss albino mouse were selected and divided into four groups. The first group was sham irradiated. The second group was irradiated with 8 Gy 60 Co gamma radiation only and served as control. The third group was administered with Ethanol extract of Punica granatum fruit rind one hour before irradiation at the dose rate of 10 mg/kg body weight orally. Animals were exposed to 8 Gy 60 Co gamma radiation. Fourth group was administered with Ethanol extract of Punica granatum fruit rind at the dose rate of 10 mg/kg body weight. Mice were sacrificed at various post irradiation intervals and liver was removed, weighed and analysed biochemically for Catalase and SOD activity. Catalase and SOD activity decreased up till 7th post irradiation day in 8 Gy irradiated group than normal. In PGFRE pretreated irradiated group catalase and SOD activity were higher than the corresponding control group at all the intervals. These results indicate that PGFRE extract protects damage to the catalase and SOD activity in liver of Swiss albino mouse against lethal dose of gamma radiation. (author)

    The present study was undertaken to determine whether total and methanol juice extracts of two Tunisian Pomegranate (Punica granatum L.) varieties (Garsi and Gabsi) protect against diarrhea as well as their effects on gastrointestinal transit (GIT) in healthy rats. In this respect, male Wistar rats were used and divided into control- and pomegranate-treated groups. The antidiarrheal activity was evaluated using the castor oil-induced diarrhea method and the GIT was assessed using charcoal meal. Our results showed that total and methanol P. granatum juice extracts produced a significant dose-dependent protection against castor oil-induced diarrhea. Pomegranate extracts and juice also decreased the GIT significantly and dose dependently. Importantly, the Garsi variety appeared to be more effective than the Gabsi variety on these two parameters. These findings suggest that pomegranate extracts have a potent antidiarrheal property in rats confirming their efficiency in the Tunisian traditional medicine.

    Punica granatum L. (Lythraceae) inhibits cancer cell proliferation and apoptosis through the modulation of cellular transcription factors and signaling proteins. No pharmacological work is reported on the effects of P. granatum juice on the cellular signaling pathways involved in initiation and progression of inflammation. The present investigation evaluates the effect of P. granatum juice (PJ) and purified punicalagin (PW) on nuclear factor kappa B (NFκB) and the signaling pathways leading to its expression in colon inflammation. Male Sprague-Dawley rats were divided into six groups: positive and negative control, vehicle (50 % ethanol), standard (5-ASA 100 mg/kg, p.o.), PJ (400 mg/kg, p.o.), PW (4 mg/kg, p.o.). Colitis was induced with 2,4-dinitrobenzene sulfonic acid and animals were euthanized on 18th day. Colon samples collected were subjected to various histological assessment (CMDI, DAI), and biochemical parameters (MPO, MDA, SOD, NO). Gene expression study was carried out using RT-PCR for cytokines (TNF-α, IL-1β, IL-18 and NF-κβ). Pretreatment with PJ and PW significantly (p granatum juice is more biologically active over punicalagin alone and can be potentially used for the treatment of inflammatory bowel disease.

    The medical application of pomegranate fruits and its peel is attracted human beings. The aim of the present study was to evaluate the in vitro α-Glucosidase inhibition, antimicrobial, antioxidant property and in vivo anti-hyperglycemic activity of Punica granatum (pomegranate) fruit peel extract using Caenorhabditis elegans. Various invitro antioxidant activity of fruit peel extracts was determined by standard protocol. Antibacterial and antifungal activities were determined using disc diffusion and microdilution method respectively. Anti-hyperglycemic activity of fruit peel was observed using fluorescence microscope for in vivo study. The ethyl acetate extract of P. granatum fruit peel (PGPEa) showed α-Glucosidase inhibition upto 50 % at the concentration of IC50 285.21 ± 1.9 μg/ml compared to hexane and methanol extracts. The total phenolic content was highest (218.152 ± 1.73 mg of catechol equivalents/g) in ethyl acetate extract. PGPEa showed more scavenging activity on 2,2-diphenyl-picrylhydrazyl (DPPH) with IC50 value 302.43 ± 1.9 μg/ml and total antioxidant activity with IC50 294.35 ± 1.68 μg/ml. PGPEa also showed a significant effecton lipid peroxidation IC50 208.62 ± 1.68 μg/ml, as well as high reducing power. Among the solvents extracts tested, ethyl acetate extract of fruit peel showed broad spectrum of antimicrobial activity. Ethyl acetate extract supplemented C.elegans worms showed inhibition of lipid accumulation similar to acarbose indicating good hypoglycemic activity. The normal worms compared to test (ethyl acetate extract supplemented) showed the highest hypoglycaemic activity by increasing the lifespan of the worms.

    Punica granatum L (pomegranate), is a shrub mostly available in the Mediterranean Sea region. The fruits have gained the substantial attention among researchers due to its promising biological activities including anti-inflammatory, antibacterial, antidiarrheal, immune modulatory, antitumor, wound healing and antifungal that have been attributed to various constituents of seeds, bark, juice, pericarp and leaf of this tree across the globe. The phenolic compounds of pomegranate have been documented to possess numbers of prophylactic and therapeutic utilities against various pathological infections as well as non-infectious disorders. The current review expedites the pharmacological role of Punica granatum L. in curing elements related to infectious and non-infectious disorders. Commencing a thorough review of the published literature and patents available on Punica granatum and its therapeutic role in countering infectious disorders present review is prepared by using various published resources available on PubMed, Med line, PubMed Central, Science Direct and other scientific databases. The information retrieved has been compiled and analyzed pertaining to the theme of the study. Multi-dimensional beneficial application of pomegranate plant is recorded. The pomegranate seed oil has phytoestrogenic compounds and the fruit is rich in phenolic compounds with strong antioxidant activity. The fruit and bark of pomegranate are used against intestinal parasites, dysentery, and diarrhea in different animals and human models. Since, ancient time the juice and seeds had considered the best therapy for throat and heart disorders. Ellagic acid is one of the main components of pomegranate with potent antioxidant activity. Results from different studies reported that Punica granatum L or its byproducts can be used as natural food additives in human and animal nutrition in order to boost immunity, microbial safety and provide the housing environment without affecting body weight

    Pomegranate (Punica granatum L.) fruits are used mainly by the juice industry, for which seeds are a by-product to be disposed of, though they could potentially be a source of bioactive compounds. In this work, germination (total germination percentage, G; mean germination time, MGT; time to reach 80% of germination, TG80; seedling shoot length, fresh weight and dry matter), and nutritional value (total phenolics, TP; total flavonoids, TF; total non-tannins, TNT; antioxidant activities) of pomegranate seeds and sprouts were determined on four commercial pomegranate cultivars (Akko, Dente di Cavallo, Mollar de Elche and Wonderful). Seeds were removed from ripe fruits and incubated in plastic trays containing sterile cotton wetted with distilled water. Sprout shoots were harvested when they reached the complete cotyledon expansion, i.e., the ready-to-eat stage. Akko showed the best germination performance (G = 98%; MGT = 14 days after sowing, DAS; TG80 = 16 DAS), followed by Mollar de Elche. Sprouting dramatically increased TP, TF, TNT and antioxidant activity in all genotypes, with the highest values recorded in Mollar de Elche and Dente di Cavallo. Overall, based on germination performance, Akko and Mollar de Elche would be the best cultivars for sprouting. Sprouting pomegranate seeds appears to be a suitable way of utilizing by-products of the juice industry to obtain bioactive compounds.

    The present study aims to evaluate the antioxidant activity of pomegranate (Punica granatum L.) peel and seed (obtained as waste from juice extraction) using different solvents as diethyl ether, ethyl acetate, ethanol 50 ⁒, ethanol 80⁒: methanol 50⁒, methanol 80⁒ and distilled water. The measurements of the antioxidant activity of all extracts were carried out using a radical scavenging activity against 2,2 ' ,-diphenyl-1-picrylhydrazyl (DPPH), β-Carotene⁒linoleic acid bleaching and ferric reducing antioxidant power (FRAP). Moreover, the effect of gamma irradiation at dose levels of 3, 6 and 9 kGy on, antioxidant activity of the best pomegranate peel and seed samples that possessed highest antioxidant activity was investigated. Results showed that ethanolic 50⁒ peel extract had a higher total phenolic contents (TPC) and total flavonoid contents (TFC) in both peel and seed, (9323.17 mg gallic acid equivalent (GAE) 100 g -1 , 2998.05 mg quercetin equivalent (QE) 100 g -1 and 352.09 mg GAE 100 g -1 ,106.78 mg QE 100 g -1 dry weight (DW), respectively than other extracts. Ethanolic 50⁒ extracts showed higher antioxidant activity than other peel and seed extracts. In addition, ethanolic 50⁒ extract of irradiated pomegranate peel and seed at dose level of 6 kGy extract had higher TPC, TFC and antioxidant activity compared to other doses. Thus, ethanolic 50⁒ extract of irradiated pomegranate peel and seed at 6 kGy may be considered as a good source of natural compounds with-antioxidant activity which could be suitable as potential ingredient for food products.

    Pomegranate fruit has been extensively used as a natural medicine in many cultures. The present study was aimed at evaluating the protective effects of pomegranate (Punica granatum) juice against carbon tetrachloride (CCl4)-induced oxidative stress and testes injury in adult Wistar rats. Twenty eight Wistar albino male rats were divided equally into 4 groups for the assessment of protective potential of pomegranate juice. Rats of group I (control) received only vehicles and had free access to food and water. Rats of groups II and IV were treated with CCl4 (2 ml/kg bwt) via the intraperitoneal route once a week for ten weeks. The pomegranate juice was supplemented via drinking water 2 weeks before and concurrent with CCl4 treatment to group IV. Group III was supplemented with pomegranate juice for twelve weeks. The protective effects of pomegranate on serum sex hormones, oxidative markers, activities of antioxidant enzymes and histopathology of testes were determined in CCl4-induced reproductive toxicity in rats. Pomegranate juice showed significant elevation in testosterone, luteinizing hormone (LH) and follicle stimulating hormone (FSH) those depleted by the injection of CCl4. Activity levels of endogenous testesticular antioxidant enzymes; superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione-S-transferase (GST) and glutathione reductase (GR) and glutathione (GSH) contents were increased while lipid peroxidation (LPO) and nitric oxide (NO) were decreased with pomegranate juice. Moreover, degeneration of germ and Leydig cells along with deformities in spermatogenesis induced after CCl4 injections were restored with the treatment of pomegranate juice. The results clearly demonstrated that pomegranate juice augments the antioxidant defense mechanism against carbon tetrachloride-induced reproductive toxicity and provides evidence that it may have a therapeutic role in free radical mediated diseases.

    Objective: Recurrent aphthous stomatitis (RAS) is a common, painful ulcerative disorder of the oral cavity with unknown etiology. No documented cure exists and topical application of medications aims to reduce pain associated with this condition. The aim of this study was to evaluate the efficacy of Punica granatum (PG) extract on the clinical management of RAS. Methods: A total of 40 patients with RAS participated in this randomized, double-blind, and placebo-controlled study. During three episodes of RAS, the efficacy of topical PG gel (10%) was evaluated. Patients were randomly assigned to use placebo gel or PG gel daily. The time of pain elimination and the time of complete healing were recorded and the pain degree was assessed and recorded by each patients in different time intervals including: Before using the oral gel (day 0), and on days 1, 3, 5, 7 after using the product. Data were analyzed using the repeated measures ANOVA, paired and independent t-test. Findings: Mean time of pain elimination showed a significant difference (P < 0.001) between PG group (3.4 ± 1.09) and placebo group (5.9 ± 0.6). The mean duration of complete healing also showed a significant difference (P < 0.001) between PG group (5.3 ± 0.81) and placebo group (8.6 ± 0.99). The visual analog scale score in PG group was significantly less than the placebo group in all time intervals (day 1 to day 7) (P < 0.001). Conclusion: The findings of this study revealed that PG extract in the form of oral gel (10%) may be beneficial in reducing RAS pain and has a positive effect in reducing the overall time period of complete healing. It was concluded that PG is an effective herbal medicine for the management of RAS. PMID:24991610

    Objectives: The antiplaque and antigingivitis effects of a gel containing 10% Punica granatum Linn extract were evaluated using a 21-day partial-mouth experimental model of gingivitis. Methods: 23 volunteers participated in this cross-over, doubleblind study, carried out in 2 phases of 21 days each. For each period of the experiment, an acrylic toothshield was made for each volunteer to carry the test or placebo gel as well as to avoid brushing of the 4 experimental teeth (posterior teeth in the lower left quadrant). The subjects were randomly assigned to use either the placebo gel (control group) or the test gel (experimental group) and were instructed to brush the remaining teeth normally 3 times a day. On days 0 and 21, the visible plaque index (VPI) and gingival bleeding index (GBI) were recorded. Results: The results did not show statistically significant difference between control and experimental groups for either of the indices (VPI and GBI). Conclusion: The gel containing 10% Punica granatum Linn extract was not efficient in preventing supragingival dental plaque formation and gingivitis. PMID:19089066

    Use of herbal extracts and essences as natural antibacterial compounds has become increasingly popular for the control of oral infectious diseases. Therefore, finding natural antimicrobial products with the lowest side effects seems necessary. The present study sought to assess the effect of Punica granatum L. water extract on five oral bacteria and bacterial biofilm formation on orthodontic wire. Antibacterial property of P. granatum L. water extract was primarily evaluated in brain heart infusion agar medium using well-plate method. The minimum inhibitory concentration and minimum bactericidal concentration were determined by macro-dilution method. The inhibitory effect on orthodontic wire bacterial biofilm formation was evaluated using viable cell count in biofilm medium. At the final phase, samples were fixed and analyzed by Scanning Electron Microscopy. The growth inhibition zone diameter was proportional to the extract concentration. The water extract demonstrated the maximum antibacterial effect on Streptococcus sanguinis ATCC 10556 with a minimum inhibitory concentration of 6.25 mg/ml and maximum bactericidal effect on S. sanguinis ATCC 10556 and S. sobrinus ATCC 27607 with minimum bactericidal concentration of 25 mg/ml. The water extract decreased bacterial biofilm formation by S. sanguinis, S. sobrinus, S. salivarius, S. mutans ATCC 35608 and E. faecalis CIP 55142 by 93.7-100%, 40.6-99.9%, 85.2-86.5%, 66.4-84.4% and 35.5-56.3% respectively. Punica granatum L. water extract had significant antibacterial properties against 5 oral bacteria and prevented orthodontic wire bacterial biofilm formation. However, further investigations are required to generalize these results to the clinical setting.

    Punica granatum (pomegranate), an edible fruit originating in the Middle East, has been used as a traditional medicine for treatment of pain and inflammatory conditions such as peptic ulcer. The numerous risks associated with nonsteroidal anti-inflammatory drugs (NSAIDs) for treatment of pain and inflammation give rise to using medicinal herbs as alternative therapies. This study aimed to evaluate the anti-inflammatory effect of isolated compounds from the ethyl acetate (EtOAc) fraction of P. granatum by determination of their inhibitory effects on lipopolysaccharide (LPS), stimulated nitric oxide (NO), prostaglandin E2 (PGE-2), interleukin-6 (IL-6) and cyclooxxgenase-2 (COX-2) release from RAW264.7 cells. The compounds ellagic acid, gallic acid and punicalagin A&B were isolated from EtOAc by high performance liquid chromatography (HPLC) and further identified by mass spectrometry (MS). The inhibitory effect of ellagic acid, gallic acid and punicalagin A&B were evaluated on the production of LPS-induced NO by Griess reagent, PGE-2 and IL-6 by immunoassay kit and prostaglandin E2 competitive ELISA kit, and COX-2 by Western blotting. Ellagic acid, gallic acid and punicalagin A&B potentially inhibited LPS-induced NO, PGE-2 and IL-6 production. The results indicate that ellagic acid, gallic acid and punicalagin may be the compounds responsible for the anti-inflammatory potential of P. granatum.

    Human and animal mycoses become more frequent and more resistant to traditional treatments. In this work, we tested the in vitro antifungal activity of acetonic extracts of Punica granatum L., Quercus suber L. and Vicia faba L. against seven pathogen fungi and the in vivo antifungal activity against Candida albicans and Trichophyton mentagrophytes. The phytochemical screening was also carried out and showed that the extracts contained mainly proanthocyanidins. Other polyphenols were also present but in low quantity. The acetone extract of V. faba L. gave a good in vitro inhibition of yeasts and was the most active for treating candidiasis in mice. It decreased the percentage of mortality with only 20μg. But the in vivo antifungal activity of this extract on T. mentagrophytes was low. It only showed a small diminution of crusting and erythema after the administration of 100μg. On the contrary, the acetone extracts of P. granatum L. had a poor activity against yeasts and a better one against moulds. It gave the best in vivo antifungal activity against T. mentagrophytes by healing animals with 40μg. The extract of P. granatum L. gave also an interesting in vivo antifungal activity against T. mentagrophytes with an active dose of 80μg. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    The present study investigated the difference between therapeutic responses of hot and cold temperament patients (based on traditional Persian medicine) with ulcerative colitis to pomegranate peel extract. Seventy-eight patients with moderate ulcerative colitis based on Lichtiger Colitis Activity Index (LCAI) criteria were randomized to receive an aqueous extract of the Punica granatum peel (6 gram per day) or placebo for four weeks. They were assessed before and after the intervention in terms of symptoms by LCAI scoring system. The results were compared in two therapeutic groups based on the patient s' temperament (cold and hot) which were diagnosed based on a previously validated questionnaire. Therapeutic response was significantly higher in patients with hot temperament compared to patients with cold temperament in the P. granatum group (1.91±0.492 vs. -0.500±0.500, P=0.029). This study showed the importance of considering syndrome differentiation and temperament in interpreting the effect of P. granatum peel extract on ulcerative colitis.

    Context • In the folk medicine of Mediterranean countries and in ancient Ayurveda, Punica granatum seeds (ie, pomegranate seeds) have been used for treatment of various disorders, including those that nowadays are classified as menopausal symptoms (MSs). Pomegranate seed oil (PSO) from those seeds mainly contains unsaturated fatty acids such as γ-linoleic acid and linolenic acid, but it also includes phytoestrogens. It is, therefore, regarded as a promising option for treating MSs today. Objectives • The study intended to investigate the safety and effectiveness of PSO as a defined P granatum seed oil for patients with MSs. Design • The research team designed an individually controlled, investigator-initiated cohort study. Setting • The treatments were performed at 2 institutions: (1) the Center for Complementary Medicine at the University Medical Center Freiburg (Freiburg, Germany); and (2) in the medical practice of H. Fischer (Freiburg, Germany). Participants • Seventy-eight patients, who had a mean duration of MSs of 46 mo, participated in the study. Intervention • After 4 wk without treatment, which functioned as a period providing an individual control, each participant took 1000 mg of PSO daily in 2 capsules for 8 wk. Outcome Measures • The symptom severity was scored on the German version of the menopausal rating scale (MRS) at baseline, after 4 wk without treatment, after 4 wk of treatment, and postintervention, with 0 = absence of symptoms and 4 = very strong symptoms. The efficacy and tolerability were estimated on scales from 0-4. Each participant's 17ß estradiol was determined at baseline and after postintervention using the patient's sera. The content of the β-sitosterol was determined in the PSO preparations by gas chromatography. Results • The content of β-sitosterol in the PSO used in the study was 6.3 mg/1000 mg. In the intention to treat analysis, most MRS symptoms were significantly and relevantly reduced (eg, hot flushes

    Punica granatum L. is widely recognized for its potency against a broad spectrum of bacterial pathogens. The purpose of this study was to explore the inhibitory and the bactericidal activities of Punica granatum against Salmonella strains. The effect of extracts obtained from different parts (peels, seeds, juice and flowers) of pomegranate and using different solvents against Salmonella enterica serovars Kentucky and Enteritidis isolated from chicken meat was thus investigated. Salmonella strains were identified with the standard API-20E system and confirmed by real time PCR. The obtained results showed that the highest antibacterial activity against Salmonella strains was observed with the peels ethanolic extract giving MIC values ranging from 10.75 to 12.5mg/mL. The ethanolic extract of P. granatum Nana peels at 0.8 and 1.6mg/g significantly inhibited the growth of Salmonella Kentucky in chicken meat stored at 4°C. The phenolic composition of the ethanolic peel extract was explored by HPLC coupled to both DAD and ESI/TOF-MS detections. The obtained results allowed the detection of 21 phytochemical compounds among which various phenolic compounds have been identified on the basis of their UV and MS spectra as well as with literature data. Among the detected compounds, anthocyanins, ellagitannins, ellagic acid derivatives and flavanols were further characterized through MS-MS analysis. Our results showed thus that the Tunisian variety Nana pomegranate constitutes a good source of bioactive compounds with potent antimicrobial activity on the growth of Salmonella strains suggesting that the studied pomegranate cultivar could be a natural remedy to minimize the emergence of Salmonella enterica strains which is often involved in food borne illness.

    Full Text Available Several products have been developed to eliminate or reduce potential pathogenic microorganisms of the oral microbiome. The continuous use of these synthetic products can result in side effects such as vomiting, diarrhea, darkening of the teeth and the induction of microbial resistance. Pomegranate (Punica granatum peel decoction was tested to assess its antimicrobial activity. In vitro analysis showed the decoction had antimicrobial activity against strains of Pseudomonas aeruginosa and Candida albicans, but none was detected against Enterococcus faecalis. When tested on saliva samples from children, the decoction showed great potential in reducing the load of microorganisms, the inhibition haloes produced with saliva samples being similar to those of the antimicrobial control (0.12% chlorhexidine. The pomegranate peel decoction in water could thus provide a promising source for developing solutions for use against oral diseases.

    The ethanol extract of Punica granatum L. rind was tested to show significant nematicidal activity against pine wood nematode. Three nematicidal compounds were obtained from the ethanol extract by bioassay-guided fractionation and identified as punicalagin 1, punicalin 2, and corilagin 3 by mass and nuclear magnetic resonance spectral data analysis. Punicalagin 1 was most active against PWN among the purified compounds with the LC 50 value of 307.08μM in 72h. According to the enzyme assays in vitro, punicalagin 1 could inhibit the activity of acetylcholinesterase, amylase and cellulase from PWN with IC 50 value of 0.60mM, 0.96mM and 1.24mM, respectively. The morphological structures of PWNs treated by punicalagin 1 were greatly changed. These physiological effects of punicalagin 1 on PWN may helpful to elucidate its nematicidal mechanism.

    Increasing anthelmintic resistance and the impact of conventional anthelmintics on the environment, it is important to look for alternative strategies against helminth parasite in sheep. Important lipogenic enzymes like glucose-6-phosphate dehydrogenase (G-6-PDH) and malate dehydrogenase (MDH) show subcellular distribution pattern. Activity of G-6-PDH was largely restricted to cytosolic fraction while MDH was found in both cytosolic and mitochondrial fraction in Gastrothylax indicus. Following in vitro treatment with ethanolic and aqueous extracts of Punica granatum fruit peel and commercial anthelmintic, albendazole G-6-PDH activity was decreased by 19-32 %, whereas MDH was suppressed by 24-41 %, compared to the respective control. Albendazole was quite effective when compared with negative control and both the extracts. The results indicate that phytochemicals of plant may act as potential vermifuge or vermicide.

    Rind of Punica granatum is traditionally used for anthelmintic purposes. The current work describes the possible anthelmintic activity of crude methanolic extract of Punica granatum (Pg. Cr) against round worms (Ascaridia galli) and the tape worms (Raillietina spiralis). Brine shrimp cytotoxicity is also performed. Brine shrimp cytotoxic activity was tested using different concentrations (1000 μg/mL, 100 μg/mL and 10 μg/mL) of Pg.Cr. In vitro anthelmintic activity of Pg. Cr was determined against the parasites using albendazole and piperazine citrate as standard anthelmintic drugs in concentration 10 mg/ml. LC50 value for Brine shrimp cytotoxicity was 189.44 ±28 μg/mL. In test concentration of 40mg/ml of the Pg. Cr, Raillietina spiralis was paralyzed in 23 minutes. However, for parasiticidal activity (death of the parasite), it took less time (40 minutes) as compared to standard Albendazole. Time taken for death of the parasite Raillietina spiralis, in concentration 40 mg /ml, is 40 min. While standard drugs took more time to kill the Raillietina spiralis. Pg. Cr took 19 minutes to paralyze the Ascaridia galli at concentration 40 mg/ml whereas; it took 48 minutes for to kill the parasite Ascaridia galli. The current work confirms the traditional use of rind of Punica granatum as anthelmintic against Raillietina spiralis and Ascaridia galli. Results of brine shrimp cytotoxicity assay warrant for the isolation of cytotoxic compounds. List of abbreviation- Pg. Cr = Crude methanolic extract of Punica granatum.

    In our previous studies, we showed the inhibitory effects of Punica granatum L. flower and Rhus coriaria L. fruit water extracts on dental plaque accumulation by several bacteria, especially Streptococcus mutans (S. mutans), on orthodontic wire by in-vitro assays. In this study, the anti-cariogenic properties of the extracts were evaluated by assessing their effects on expression of glycosyltransferase (gtf) genes, which are responsible for initial biofilm formation by S. mutans. In this study, the effect of herbal extracts on expression of gtfB, C (encoding enzymes that produce water-insoluble glucans) and D (encoding enzymes that produce water-soluble glucans) genes in S. mutans growing in planktonic state was evaluated quantitatively by real-time polymerase chain reaction (PCR) method. The minimum biofilm inhibitory concentration (MBIC) of understudied herbal water extracts significantly suppressed gtfB, C and D gene expression by 85.3 ± 7.5%, 33.3 ± 6.4% and 25 ± 14%, respectively for Punica granatum L. extract and 73.4 ± 7.3%, 93.8 ± 2.7% and 59.3 ± 9.8%, respectively for Rhus coriaria L. extract compared to the non-treated control group (P Punica granatum L. extract. These findings suggest that Punica granatum L. and especially Rhus coriaria L. maybe used as novel, natural antiplaque agents since they inhibit specific genes associated with bacterial biofilm formation without necessarily affecting the growth of oral bacteria.

    Candida species are opportunistic fungi, among which, Candida albicans is the most important species responsible for infections in immunocompromised patients with invasive fungal disease. Resistance of Candida species to antifungal drugs has led scientists to pay more attention to traditional medicine herbs. Due to the limitations in the treatment of fungal diseases such as shortages, high prices, antifungal side effects and drug resistance or reduced susceptibility to fungal drugs we decided to study the antifungal effects of herbal extracts of Syzygium aromaticum and Punica granatum. Twenty-one isolates of oral C. albicans in patients with denture stomatitis referred to prosthesis department, Dental faculty of Tehran University of Medical Sciences were prepared and cultured. Plant extracts were prepared from the herbs market. Tests on patient samples and standard strains 5027ATCC (PTCC10231) yeast C. albicans were performed via well diffusion method. In addition, nystatin and methanol were used as positive and negative control, respectively. Finally, the antifungal effect of extracts using Statistical Repeated measurement ANOVA test was investigated. Both S. aromaticum and P. granatum showed noticeable antifungal activity in well method. Syzygium aromaticum showed better anti candida activity than nystatin (Pgranatum showed good antifungal effects (P-value<0.001). S. aromaticum (inhibition zone diameter: 29.62) showed better antifungal effects than nystatin (inhibition zone diameter: 28.48). Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    This study was aimed to examine the anti-epileptic activity of leaf extracts of Punica granatum in experimental models of epilepsy in Swiss albino mice. Petroleum ether leaf extract of P. granatum (PLPG), methanolic LPG (MLPG), and aqueous LPG (ALPG) extracts of P. granatum leaves was initially evaluated against 6-Hz-induced seizure model; the potent extract was further evaluated against maximal electroshock (MES) and pentylenetetrazole (PTZ)-induced convulsions. Further, the potent extract was evaluated for its influence on Gamma amino butyric acid (GABA) levels in brain, to explore the possible mechanism of action. In addition, the potent extract was subjected to actophotometer test to assess its possible locomotor activity deficit inducing action. In 6-Hz seizure test, the MLPG has alleviated 6-Hz-induced seizures significantly and dose dependently at doses 50, 100, 200, and 400 mg/kg. In contrast, PLPG and ALPG did not show any protection, only high dose of ALPG (400 and 800 mg/kg, p.o.) showed very slight inhibition. Based on these observations, only MLPG was tested in MES and PTZ models. Interestingly, the MLPG (50, 100, 200 and 400 mg/kg) has offered significant and dose-dependent protection against MES ( P < 0.01) and PTZ-induced ( P < 0.01) seizures in mice. Further, MLPG showed a significant increase in brain GABA levels ( P < 0.01) compared to control and showed insignificant change in locomotor activity in all tested doses (100, 200 and 400 mg/kg). Interestingly, higher dose of MLPG (400 mg/kg, p.o.) and Diazepam (5 mg/mg, p.o.) have completely abolished the convulsions in all the anticonvulsant tests. These findings suggest that MLPG possesses significant anticonvulsant property, and one of the possible mechanisms behind the anticonvulsant activity of MLPG may be through enhanced GABA levels in the brain.

    The optimum extraction of ursolic acid from Punica granatum peel by SFE-CO2 was investigated. Based on the design of Plackett-Burman(PB), significant factors influencing the yield of ursolic acid in the operation process were filtered, with the extraction rate of ursolic acid as the index. The results obtained by steepest ascent method approximated the maximum area of ursolic acid yield. Then the Central Composite Design(CCD) design was used to carry on the response surface optimization of significant factors, getting a two order mathematical model affecting the ursolic acid yield, as well as the optimum process conditions. The best technological conditions of the extraction of ursolic acid from Punica granatum peel by SFE-CO2 were that the extraction temperature was 46. 29 °C, extraction time was 91. 6 min and the extraction pressure was 34. 49 MPa. Under the optimal conditions, verification test of ursolic acid yield was 12. 508 mg/g, approximating to the predicted value of 12. 645 mg/g. The PB test and CCD test design are combined to optimize the extraction process of ursolic acid from Punica granatum peel by SFE-CO2. The screening results are statistically significant and the process operation is feasible.

    Oxidative stress is one of the major mechanisms implicated in inorganic arsenic poisoning. Punica granatum is known by its free radical scavenging properties. The aim of this study was to evaluate the protective role of combined selenium and P. granatum against arsenic-induced liver injury. Seventy-five female albino rats were divided into five groups (of 15 rats each). Toxicity was induced by oral sodium arsenite (5.5 mg/kg body weight (bw) daily) (group ІІ). Treatment of arsenic-intoxicated rats was induced by daily oral administration of sodium selenite (3 mg/kg bw) (group ІІІ), 100 mg of P. granatum ethanol extract per kilogram body weight dissolved in 300 mL distilled water in three divided doses (100 mL of this suspension every 8 h) (group IV), and combined daily oral treatment with both selenite and P. granatum ethanol extract (group V). After 3 weeks, serum and liver tissues were obtained from the decapitated rats for different estimations. Hepatotoxicity was demonstrated by significant elevation in liver weights and activities of liver enzymes, alanine aminotransferase (ALT) and aspartate aminotransferase (AST), and decrease in serum total proteins and albumin (p granatum and selenium. It was concluded that combined P. granatum and selenium treatment had a synergistic hepatoprotective effect against arsenic toxicity through activation of Nrf2 anti-oxidant pathway.

    To investigate the effects of the Punica granatum peel extract on symptoms of patients with ulcerative colitis (UC). Patients with UC were randomized to receive an aqueous extract of the P. granatum peel (6 g of dry peel/day) or placebo for four weeks complementary to standard medications. Symptoms were assessed using the Lichtiger Colitis Activity Index (LCAI) at baseline, week 4, and week 10 (follow-up). Clinical response was defined by ≥ 3 point decrease in LCAI. The LCAI score was similarly reduced in both the P. granatum (-1.68 ± 3.85, P = 0.019) and placebo groups (-1.39 ± 2.41, P = 0.002). Clinical response was higher with P. granatum compared with placebo at week 4 (41.4% vs. 18.2%, P = 0.055), but not at week 10 (48.3% vs. 36.4%, P = 0.441). The P. granatum peel extract seems effective in complementary management of UC. Further studies in a larger sample of patients are warranted. IRCT2014040617156N1. Copyright © 2015 Elsevier Ltd.

    Gentamicin is widely used as an antibiotic for the treatment of gram negative infections. Evidences indicates that oxidative stress is involved in gentamicin-induced nephrotoxicity. In Ayurvedic medicine, Punica granatum Linn. is considered as 'a pharmacy unto itself". It has been claimed in traditional literature, to treat various kidney ailments due to its antioxidant potential. To explore the possible mechanism of action of methanolic extract of P.granatum leaves (MPGL) in exerting a protective effect on gentamicin-induced nephropathy. Animals were administered with gentamicin (80 mg/kg/day i.m.) and simultaneously with MPGL (100, 200 and 400 mg/kg p.o.) or metformin (100 mg/kg p.o.) for 8 days. A satellite group was employed in order to check for reversibility of nephrotoxic effects post discontinuation of gentamicin administration. At the end of the study, all the rats were sacrificed and serum-urine parameters were investigated. Antioxidant enzymes and tumor necrosis factor alpha (TNF-α) levels were determined in the kidney tissues along with histopathological examination of kidneys. Increase in serum creatinine, urea, TNF-α, lipid peroxidation along with fall in the antioxidant enzymes activity and degeneration of tubules, arterioles as revealed by histopathological examination confirmed the manifestation of nephrotoxicity caused due to gentamicin. Simultaneous administration of MPGL and gentamicin protected kidneys against nephrotoxic effects of gentamicin as evidenced from normalization of renal function parameters and amelioration of histopathological changes. Data suggests that MPGL attenuated oxidative stress associated renal injury by preserving antioxidant enzymes, reducing lipid peroxidation and inhibiting inflammatory mediators such as TNF-α.

    Full Text Available The comprehensive identification of phenolic compounds in food and beverages is a crucial starting point for assessing their biological, nutritional, and technological properties. Pomegranate (Punica granatum L. has been described as a rich source of (polyphenolic components, with a broad array of different structures (phenolic acids, flavonoids, and hydrolyzable tannins and a quick, high throughput, and accurate screening of its complete profile is still lacking. In the present work, a method for UHPLC separation and linear ion trap mass spectrometric (MSn characterization of pomegranate juice phenolic fraction was optimized by comparing several different analytical conditions. The best solutions for phenolic acids, anthocyanins, flavonoids, and ellagitannins have been delineated and more than 70 compounds have been identified and fully characterized in less than one hour total analysis time. Twenty-one compounds were tentatively detected for the first time in pomegranate juice. The proposed fingerprinting approach could be easily translated to other plant derived food extracts and beverages containing a wide array of phytochemical compounds.

    This work describes the isolation and characterization of the hydrolysable tannin punicalagin, obtained from the yellow peel of pomegranate (Punica granatum, belonging to the family Lythraceae). The natural product was present as a mixture of α and β anomers, rapidly interconverting under acidic pH conditions. A fast and efficient purification method was established using semi-preparative high performance liquid chromatography (HPLC). The chemical structure of the molecule was confirmed as punicalagin based on IR spectroscopy, 1H and 13C NMR, and MALDI-TOF mass spectrometry studies. The lowest energy conformations of the α and β anomers were calculated by quantum chemical methods, and their ratio compared to the experimental value (experimental: α/β = 2.2 to 2.5; calculated α/β = 2.4, in aqueous solution at acidic pH). The antioxidant activity of pure punicalagin was determined with a DPPH radical scavenging assay (IC50 = 1.9 ± 0.2 μg/mL) and was comparable to that of tannic acid (IC50 = 1.3 ± 0.2 μg/mL). Finally, we demonstrated that punicalagin, when used above a threshold concentration, was able to precipitate bovine serum albumin (BSA), although less efficiently than tannic acid.

    The pomegranate (Punica granatum L.) fruit has a long history of human consumption and possesses notable antioxidant and cardiovascular properties. This work evaluated the feasibility to provide a new functional beverage based on a dealcoholized red wine matrix supplemented by a pomegranate extract. The potential bioactive compounds in the pomegranate extract, punicalagin A and B and ellagic acid, were analyzed during the downstream process in order to evaluate the functional dose in the final beverage. The addition of pomegranate extract to the dealcoholized red wine resulted in a product with more intense yeast odor, acidity, yeast flavor, and astringency and with a less intense berry flavor. Consumer acceptance of the product was also investigated and the results revealed the existence of a niche of consumers willing to consume dealcoholized wine enriched with pomegranate extract. After tasting, 50% and 40% of those consumers initially interested by this product concept declared to be interested to purchase the control sample and the functional beverage, respectively. The daily consumption of two servings of 250 mL of this new pomegranate-enriched dealcoholized wine provides 82 mg of total ellagitannins, corresponding to the sum of punicalagin A and B and ellagic acid. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Differentiation refers to the ability of cancer cells to revert to their normal counterparts, and its induction represents an important noncytotoxic therapy for leukemia, and also breast, prostate, and other solid malignancies. Flavonoids are a group of differentiation-inducing chemicals with a potentially lower toxicology profile than retinoids. Flavonoid-rich polyphenol fractions from the pomegranate (Punica granatum) fruit exert anti-proliferative, anti-invasive, anti-eicosanoid, and pro-apoptotic actions in breast and prostate cancer cells and anti-angiogenic activities in vitro and in vivo. Here we tested flavonoid-rich fractions from fresh (J) and fermented (W) pomegranate juice and from an aqueous extraction of pomegranate pericarps (P) as potential differentiation-promoting agents of human HL-60 promyelocytic leukemia cells. Four assays were used to assess differentiation: nitro blue tetrazolium reducing activity, nonspecific esterase activity, specific esterase activity, and phagocytic activity. In addition, the effect of these extracts on HL-60 proliferation was evaluated. Extracts W and P were strong promoters of differentiation in all settings, with extract J showing only a relatively mild differentiation-promoting effect. The extracts had proportional inhibitory effects on HL-60 cell proliferation. The results highlight an important, previously unknown, mechanism of the cancer preventive and suppressive potential of pomegranate fermented juice and pericarp extracts.

    Hydrolyzable tannins (HTs) play important roles in plant herbivore deterrence and promotion of human health. A critical step in HT production is the formation of 1-O-galloyl-β-D-glucopyranoside (β-glucogallin, ester-linked gallic acid and glucose) by a UDP-glucosyltransferase (UGT) activity. We cloned and biochemically characterized four candidate UGTs from pomegranate (Punica granatum), of which only UGT84A23 and UGT84A24 exhibited β-glucogallin forming activities in enzyme assays. Although overexpression and single RNAi knockdown pomegranate hairy root lines of UGT84A23 or UGT84A24 did not lead to obvious alterations in punicalagin (the prevalent HT in pomegranate) accumulation, double knockdown lines of the two UGTs resulted in largely reduced levels of punicalagins and bis-hexahydroxydiphenyl glucose isomers. An unexpected accumulation of galloyl glucosides (ether-linked gallic acid and glucose) was also detected in the double knockdown lines, suggesting that gallic acid was utilized by an unidentified UGT activity for glucoside formation. Transient expression in Nicotiana benthamiana leaves and immunogold labeling in roots of pomegranate seedlings collectively indicated cytosolic localization of UGT84A23 and UGT84A24. Overall, functional characterization and localization of UGT84A23 and UGT84A24 open up opportunities for further understanding the regulatory control of HT metabolism in plants and its coordination with other biochemical pathways in the metabolic network.

    This study revealed polyphenolic content, nutritive content, antioxidant activity, and phenolic profile of methanol and aqueous extracts of Punica granatum peel extract. For this, extracts were screened for possible antioxidant activities by free radical scavenging activity (DPPH), hydrogen peroxide scavenging activity and ferric-reducing antioxidant power (FRAP) assays. The total phenolics and flavonoid recovered by methanolic (MPE) and the water extract (AQPE) were ranged from 185 ± 12.45 to 298.00 ± 24.86 mg GAE (gallic acid equivalents)/gm and 23.05 ± 1.54 to 49.8 ± 2.14 quercetin (QE) mg/g, respectively. The EC50 of herbal extracts ranged from 100 µg/ml (0.38 quercetin equivalents), for AQPE, 168 µg/ml (0.80 quercetin equivalents), for MPE. The phenolic profile in the methanolic extracts was investigated by chromatographic (HPLC) method. About 5 different flavonoids, phenolic acids, and their derivatives including quercetin (1), rutin (2), gallic acid (3), ellagic acid (4), and punicalagin as a major ellagitannin (5) have been identified. Among both extracts, methanolic extract was the most effective. This report may be the first to show nutritive content and correlation analysis to suggest that phenols and flavonoids might contribute the high antioxidant activity of this fruit peel and establish it as a valuable natural antioxidant source applicable in the health food industry.

    The objective of this study was to investigate the protective effects of pomegranate (Punica granatum) juice (PGJ) on oxidative damages in liver tissue and erythrocytes of rats intoxicated by sodium fluoride (NaF). Rats were randomly divided into two groups: group I received standard diet and group II received orally 1 mL of PGJ. After 5 weeks of pretreatment, each group was divided again into two subgroups and treated for another 3 weeks as follows: group I was subdivided into a control group and a group that was treated with 100 ppm of NaF (in drinking water); group II was subdivided into one group that was treated daily with both 100 ppm NaF and PGJ (1 mL orally) and one that received daily 1 mL of pomegranate juice. Exposure to NaF decreased hematological parameters, changed the total protein, albumin, bilirubin levels, and increased the activities of hepatic marker enzymes. We also noted an increase in lipid peroxidation contents, accompanied by a decrease of reduced glutathione levels. Antioxidant enzyme activities in both tissues were modified in the NaF group compared with the control group. However, the administration of PGJ juice caused an amelioration of the previous parameters. Our results indicated the potential effects of NaF to induce oxidative damage in tissues and the ability of PGJ to attenuate NaF-induced oxidative injury.

    Due to the increase of bacterial resistance, medicinal alternatives are being explored. Punica granatum L. is an effective herbal extract with broad spectrum of action and bactericidal, antifungal, anthelmintic potential and being able to modulate the immune response. The aim was to evaluate the antimicrobial activity of pomegranate glycolic extract (PGE) against the periodontal pathogen Porphyromonas gingivalis by using Galleria mellonella as in vivo model. Fifteen larvae were used per group. Injection of high concentration (200, 100, and 25 mg/mL) of PGE showed a toxic effect, leading them to death. A suspension of P. gingivalis (106 cells/mL) was inoculated in the left last proleg and PGE (12.5, 6.25, 3.1, and 2.5 mg/mL) were injected into the right proleg. The larvae were then kept at 37°C under the dark. Injection of PGE at any dose statistically improved larvae survival rates. The data were analysed (log-rank test, Mantel-Cox, P < 0.05) and showed that all concentrations of PGE (12.5, 6.25, 3.1, and 2.5 mg/mL) presented higher larval survival rates, with significant statistical difference in relation to control group (P. gingivalis). In conclusion, the PGE had antimicrobial action against P. gingivalis in vivo model using G. mellonella. PMID:27668280

    The sun-dried rind of the immature fruit of pomegranate (Punica granatum) is presently used as a herbal formulation (OMARIA, Orissa Malaria Research Indigenous Attempt) in Orissa, India, for the therapy and prophylaxis of malaria. The pathogenesis of cerebral malaria, a complication of the infection by Plasmodium falciparum, is an inflammatory cytokine-driven disease associated to an up-regulation and activity of metalloproteinase-9 and to the increase of TNF production. The in vitro anti-plasmodial activity of Punica granatum (Pg) was recently described. The aim of the present study was to explore whether the anti-malarial effect of OMARIA could also be sustained via other mechanisms among those associated to the host immune response. From the methanolic extract of the fruit rind, a fraction enriched in tannins (Pg-FET) was prepared. MMP-9 secretion and expression were evaluated in THP-1 cells stimulated with haemozoin or TNF. The assays were conducted in the presence of the Pg-FET and its chemical constituents ellagic acid and punicalagin. The effect of urolithins, the ellagitannin metabolites formed by human intestinal microflora, was also investigated. Pg-FET and its constituents inhibited the secretion of MMP-9 induced by haemozoin or TNF. The effect occurred at transcriptional level since MMP-9 mRNA levels were lower in the presence of the tested compounds. Urolithins as well inhibited MMP-9 secretion and expression. Pg-FET and pure compounds also inhibited MMP-9 promoter activity and NF-kB-driven transcription. The beneficial effect of the fruit rind of Punica granatum for the treatment of malarial disease may be attributed to the anti-parasitic activity and the inhibition of the pro-inflammatory mechanisms involved in the onset of cerebral malaria.

    Urinary lithiasis is a recurrent disease defined by the presence of calculi in the urinary tract. Most urinary calculi have as a major component calcium oxalate which occurs mainly in two crystalline forms: Calcium oxalate monohydrate (whewellite) and calcium oxalate dihydrate (weddellite). The target behind, this work is to study the inhibiting effect of the calcium oxalate's crystallization by the extract of the Ammi visnaga and the Punica granatum. The inhibition of crystallization has been studied in vitro with both the absence and the presence of the different concentrations of the extracts of the two plants. This study consists in measurement, with the UV-Visible spectrophotometer, the temporal evolution of the optical density at λ equal to 620nm corresponding to the formation of the crystals due to the mixing of metastable solutions of calcium and oxalate. The characterization of the crystals is carried out in parallel by both the Fourier transform infrared spectra (FT-IR) and the observation of the crystals with the help of an optical microscope. In this respect, the inhibition percentages were calculated from the turbidity slopes in the presence and absence of the extract. The results obtained were more effective, especially for Punica granatum with percentages of 97.8±0.12 and 83.46±1.34% against nucleation and aggregation, respectively, the order of Ammi visnaga was as follow: 73.25±0.81 and 59.44±3.3%. Thus, all correlation coefficients are greater than 0.95 and all coefficients of variation are less than 10%. The prevention and treatment of urinary lithiasis and especially in the case of recurrence by plants remains an alternative choice for medical methods. This study justified the efficacy of the plants Ammi visnaga and in particular Punica granatum against the crystallization of calcium oxalate. 3. Copyright © 2017 Elsevier Masson SAS.

    Ionizing radiations produce deleterious effects in the living organisms and the rapid technological advancement has increased human exposure to ionizing radiations enormously. Radiotherapy, which is a chief modality to treat cancer, faces a major drawback because it produces severe side effects developed due to damage to normal tissue by reactive oxygen species (ROS). Recent studies have indicated that some commonly used medicinal plants may be good sources of potent but non-toxic radioprotectors. The pomegranate, Punica granatum L., an ancient, mystical, and highly distinctive fruit, is the predominant member of the Punicaceae family. It is used in several systems of medicine for a variety of ailments. The objective of the present study was to investigate the protective effects of ethanolic extracts of pomegranate whole fruit (EPWF) and seeds (EPS) and Synthetic Ellagic acid (EA) against Electron beam radiation(EBR) induced biochemical alterations in Swiss albino mice. The extracts and synthetic compound were assessed for its radical scavenging property by DPPH radical scavenging and Ferric Reducing Antioxidant Power assays. The animals were exposed to sub-lethal dose (6 Gy) of Electron Beam Radiation and then treated with 200 mg/kg body wt. of pomegranate extracts and synthetic ellagic acid for 15 consecutive days. The biochemical estimations were carried out in the liver homogenate of the sacrificed animals. Radiation induced depletion in the level of reduced glutathione and total antioxidant capacity were prevented significantly by EPWF, EPS and EA administration. Also there was significant reduction in the levels of membrane lipid peroxidation in the treated groups compared to irradiated control. The findings of our study indicate the protective efficacy of pomegranate extracts and synthetic ellagic acid on radiation induced biochemical changes in mice may be due to its free radical scavenging and increased antioxidant levels.

    Peroxisome proliferator-activated receptor (PPAR)-γ activators are widely used in the treatment of type 2 diabetes because they improve the sensitivity of insulin receptors. Punica granatum flower (PGF) has been used as an anti-diabetic medicine in Unani medicinal literature. The mechanism of actions is, however, unknown. In the current study, we demonstrated that 6-week oral administration of methanol extract from PGF (500 mg/kg, daily) inhibited glucose loading-induced increase of plasma glucose levels in Zucker diabetic fatty rats (ZDF), a genetic animal model for type 2 diabetes, whereas it did not inhibit the increase in Zucker lean rats (ZL). The treatment did not lower the plasma glucose levels in fasted ZDF and ZL rats. Furthermore, RT-PCR results demonstrated that the PGF extract treatment in ZDF rats enhanced cardiac PPAR-γ mRNA expression and restored the down-regulated cardiac glucose transporter (GLUT)-4 (the insulin-dependent isoform of GLUTs) mRNA. These results suggest that the anti-diabetic activity of PGF extract may result from improved sensitivity of the insulin receptor. From the in vitro studies, we demonstrated that the PGF extract enhanced PPAR-γ mRNA and protein expression and increased PPAR-γ-dependent mRNA expression and activity of lipoprotein lipase in human THP-1-differentiated macrophage cells. Phytochemical investigation demonstrated that gallic acid in PGF extract is mostly responsible for this activity. Thus, our findings indicate that PPAR-γ is a molecular target for PGF extract and its prominent component gallic acid, and provide a better understanding of the potential mechanism of the anti-diabetic action of PGF

    Full Text Available Purpose: Recurrent aphthous stomatitis is a disease with unknown etiology that’s mostly treated symptomatically and has no definite cure. Pomegranate (Punica granatum flowers have been used as medicinal herb that due to its antimicrobial, antioxidant, anti-inflammatory, analgesic and healing effects, has been useful in treatment of oral aphthous. Therefore, we decided to formulate a mucoadhesive gel with pomegranate flower extract to reduce the need for corticosteroid therapy in patients. Methods: Pomegranate flowers are extracted by percolation method. Several formulations with different amounts of carbomer 934, sodium carboxymethylcellulose (SCMC and hydroxypropyl methylcellulose K4M were prepared and the condensed extract was dispersed in polyethyleneglycol (PEG 400 and added to gel bases. Then the formulations underwent macroscopic and microscopic studies. The formulations that passed these tests successfully were studied through assay tests using spectrophotometry in 765 nm, drug release from mucoadhesive gel using cell diffusion method, viscosity test, mucoadhesion test and accelerated stability test. Results: The phenolic content of pomegranate flower dried extract was found to be 212.3±1.4 mg/g in dried extract. The F4–F6 formulations contains carbomer 934, SCMC, pomegranate flower extract, PEG 400, potassium sorbate and purified water passed all above tests. Conclusion: The F4 formulation had higher viscosity and mucoadhesion values due to its higher carbomer 934 and SCMC content. Since F4, F5 and F6 had no significant variation in drug release, the F4 formulation was chosen as the superior formulation because of proper appearance and uniformity, acceptable viscosity, mucoadhesion and stability in different temperatures.

    Background Rhaponticum cathamoides (RC) is an endemic wild Siberian herb with marked medicinal properties that are still poorly understood. The aim of this study is to investigate the therapeutic potential of RC extract (ERC) compared to the effects of Glycyrrhiza glabra (EGG) and Punica granatum extracts (EPG) in a rat model with high-fat diet-(HFD)-induced signs of metabolic syndrome; therefore, this study addresses a significant global public health problem. Methods Six-month-old male Wistar Albino Glaxo rats were subjected to eight weeks of a standard diet (SD), HFD, or HFD in which ERC, EGG, or EPG powders were incorporated at 300 mg/kg/day. The serum lipid profile, corticosterone and cytokine concentrations, glucose tolerance, systolic blood pressure, triacylglycerol accumulation, and PPARα DNA-binding activities in the liver samples were determined. Results In contrast to EGG and EPG, an ERC supplement significantly reduced the weight of epididymal tissue (19.0%, p < 0.01) and basal serum glucose level (19.4%, p < 0.05). ERC improved glucose intolerance as well as dyslipidemia more efficiently than EGG and EPG. EGG but not ERC or EPG supplementation decreased systolic blood pressure by 12.0% (p < 0.05). All of the tested extracts reduced serum IL6 and corticosterone levels induced by HFD. However, the lowering effects of ERC consumption on the serum TNF-α level and its restoring effect on the adrenal corticosterone level significantly exceeded the improvements induced by EGG and EPG. ERC intake also reduced triacylglycerol accumulation and increased the PPARα DNA-binding activity in the liver more significantly than EGG and EPG. Conclusions ERC powder supplementation improved glucose and lipid metabolism more significantly than EGG and EPG in rats fed on HFD, supporting the strategy of R. carthamoides use for safe relief of metabolic syndrome and its related disturbances such as inflammation, stress, and hepatic steatosis.

    FLOWERING LOCUS T (FT) and TERMINAL FLOWER1/CENTRORADIALIS (TFL1/CEN) are the key regulators of flowering time in plants with FT promoting flowering and TFL1 repressing flowering. TFL1 also controls floral meristem identity and its maintenance. In this study we have characterized two pomegranate (Punica granatum L.) TFL1/CEN-like genes designated as PgTFL1 and PgCENa. The expression of PgTFL1 and PgCENa fluctuated through alternate pruning and flowering cycles, being highly expressed during the vegetative phase (immediately after pruning) and decreasing gradually in the months thereafter such that their lowest levels, especially for PgCENa coincided with the flowering phase. Both the genes are able to functionally suppress the Arabidopsis tfl1-14 mutant flowering defect. Their expression in Arabidopsis resulted in delayed flowering time, increased plant height and leaf number, branches and shoot buds as compared with wild type, suggesting that PgTFL1 and PgCENa are bonafide homologs of TFL1. However, both the genes show distinct expression patterns, being expressed differentially in vegetative shoot apex and floral bud samples. While PgTFL1 expression was low in vegetative shoot apex and high in flower bud, PgCENa expression showed the opposite trend. These results suggest that the two TFL1s in pomegranate may be utilized to control distinct developmental processes, namely repression of flowering by PgCENa and development and growth of the reproductive tissues by PgTFL1 via distinct temporal and developmental regulation of their expression. © The Author(s) 2017.

    Acute pancreatitis (AP) refers to afflicted inflammation of pancreas with unfavorable adverse effects and developed multiple organ failures. Unfortunately, there is not a certain therapeutic method for this disease. Oxidative stress has a serious role in the pathogenesis of AP. Thus, decreasing of oxidative stress may prevent induction and progression of AP. Punica granatum L. has been extensively used in traditional medicine and possesses various active biological elements. Due to antioxidant and anti-inflammatory properties of pomegranate, it could be considered as a good candidate alternative medicine with beneficial effects on AP. In this study, we decided to study the protective effect of three fractions of pomegranate seeds on cerulein-induced AP. AP was induced in male Syrian mice by five intraperitoneal (i.p.) injection of cerulein (50 μg/kg) with 1 h intervals. Treatments with pomegranate freeze-dried powder (PFDP) and hydroalcoholic pomegranate seeds extract (PSE) at doses of 125, 250, 500 mg/kg (i.p.) were started 30 min before pancreatitis induction. Pomegranate seed oil fraction (PSOF) was orally administered (50, 100, 200 μL/kg) and continued for 10 days. Pancreatic tissue was evaluated for histopathological parameters and pancreatic myeloperoxidase (MPO) activity as well as lipase and amylase levels were measured in plasma. The higher doses of three fractions (250 and 500 mg/kg for PFDP and PSE and doses of 100, 200 μL/kg for PSOF) significantly reduced amylase and lipase activity in serum (at least P < 0.01), pancreatic MPO activity (P < 0.001), edema, leukocyte infiltration and vacuolization in comparison to the control group (P < 0.05). These results propose that pomegranate seeds fractions can prevent and/or treat the AP.

    Autoimmune hepatitis (AIH) is a chronic inflammatory liver disease of an unknown etiology, glucocorticoid therapy is currently recognized as an effective treatment for AIH, but conventional application and patient compliance are both hindered by its side effects. The exploration of the AIH pathogenesis and the searching for the new candidate drugs that exert potential activity and low toxicity are urgently needed. Pomegranate peel extract (PoPx) is a natural extract of Punica granatum and has been reported to have anti-inflammatory and antioxidative properties. The present study aimed to clarify the effect of PoPx on the concanavalin A (ConA)-induced autoimmune hepatitis in a mouse model that is well established at 12h after tail vein injection with a dose of 20 mg/kg of ConA. C57BL/6 female mice were pretreated with PoPx (250 mg/kg, once daily for 3 days) followed by a ConA challenge. Pretreatment with PoPx significantly alleviated ConA-induced liver injury by down-regulating the levels of plasma alanine transaminase (ALT), aspartate transaminase (AST) and cytokine, including TNF-α, interferon (IFN) -γ and interleukin (IL)-6. Moreover, liver hematoxylin and eosin (H&E) staining displayed a lighter inflammatory infiltration around the portal area in the PoPx-pretreated mice. In addition, the flow cytometry (FCM) data showed that the immune response in the liver was died down in the PoPx-pretreated condition. Specially, pretreatment with PoPx reduced the infiltration of activated CD4 + and CD8 + T cells in the liver. Taken together, these findings contributed to a better understanding of the actions of PoPx against acute AIH and indicated that PoPx might be a potential compound in treating T cell-mediated autoimmune liver injury.

    A robust synthesis of silver nanoparticles (AgNPs) using the peel extract of Punica granatum is reported in this article. The formation of AgNPs was confirmed by the appearance of brownish yellow color and the Surface Plasmon Resonance (SPR) peak at 432 nm. The biogenic AgNPs were found to have the size approximately 30 nm with distorted spherical shape. The high negative zeta potential values of AgNPs revealed their high stability which could be attributed to the capping of AgNPs by the phytoconstituents of the Punica granatum peel. The biogenic AgNPs were also found to function as an effective green catalyst in the reduction of anthropogenic pollutant viz., 4-nitrophenol (4-NP) by solid sodium borohydride, which was evident from the instantaneous color change of bright yellow (400 nm) to colorless (294 nm) solution, after the addition of AgNPs. The catalytic action of biogenic AgNPs in the reduction of 4-NP could be explained on the basis of Langmuir-Hinshelwood model.

    Full Text Available The genetic diversity among Tunisian pomegranate cultivars has been investigated. Using universal primers, the random amplified polymorphic DNA (RAPD method was used to generate banding profiles from a set of twelve cultivars. Data was then computed with appropriate programs to construct a dendrogram illustrating the relationships between the studied cultivars. Our data proved the efficiency of the designed method to examine the DNA polymorphism in this crop since the tested primers are characterized by a collective resolving power of 12.83. In addition, the cluster analysis has exhibited a parsimonious tree branching independent from the geographic origin of the cultivars. In spite of the relatively low number of primers and cultivars, RAPD constitutes an appropriate procedure to assess the genetic diversity and to survey the phylogenetic relationships in this crop.

    We investigated anti-diabetic, hypolipedimic and antioxidant activity of hydroalcoholic extract from leaves and fruit peel of Punica granatum. Streptozotocin induced diabetic Wister rats were used in this study consisting of seven groups of six animals each. Groups (1) normal control, (2) diabetic control, (3) leaves extract 100 mg/kg b.w. of P. granatum, (4) leaves extract 200 mg/kg b.w. of P. granatum, (5) fruit peel extract 100 mg/kg b.w. of P. granatum, (6) peel extract 200 mg/kg b.w. of P. granatum and (7) glibenclamide respectively. Fasting blood sugar was recorded on 1(st), 7(th), 14(th), 21(st) and 28(th) day. At the end of the experiment Lipid profile and levels of antioxidants were determined. Safety profile of both extracts was evaluated using acute and chronic toxicity studies. Higher dose of fruit peel extract of P. granatum (PEPG) and glibenclamide significantly lowered blood glucose level from 7(th) day onwards however glibenclamide was found to be more effective. Leaves extract at higher dose and fruit extract at lower dose also significantly lowered blood glucose level from 14(th) day onwards. Leaves extract at lower dose also significantly lowered blood glucose level from 21(st) day onwards. Glibenclamide and higher dose of fruit PEPG extract significantly reduced the total cholesterol, triglyceride levels and significantly increased the high density lipoprotein cholesterol level. Glibenclamide followed by higher dose was found more effective in reducing plasma thiobarbituric acid reactive substances and increasing levels of antioxidant enzymes (superoxide dismutase and catalase). No toxicity was observed even when both extracts were administered at 10 times of higher dose used in this study and no significant changes were seen when it were used chronically. Leaves and fruit PEPG possesses significant anti-diabetic, hypolipedimic and antioxidant properties. This study supports the traditional use of P. granatum in diabetes. Fruit peel which is

This study was aimed to seek whether an ethanolic extract of Punica granatum fruit inhibits 8-iso-PGFα formation and modulates nitric oxide (NO) in endothelial cells induced by plasma from pre-eclamptic patients. Endothelial cells were cultured from human umbilical vein endothelial cells. At confluence, endothelial cells were divided into five groups, which included endothelial cells exposed to 2% plasma from normal pregnancy (NP), endothelial cells exposed to 2% plasma from pre-eclamptic patients (PP), endothelial cells exposed to PP in the presence of ethanolic extract of P. granatum (PP+PG) at the following three doses: 14; 28; and 56 ppm. Analysis of 8-iso-PGFα was done by immunoassay technique. Analysis of NO level was done by colorimetric technique. Plasma from PP significantly increased 8-iso-PGFα level compared to cells treated by normal pregnancy plasma. This increase in 8-iso-PGFα was significantly (pgranatum extract. The level of NO was insignificant (p>0.05) between groups. P. granatum fruit extract protects endothelial cells from oxidative stress induced by plasma from pre-eclamptic patients.

    A new flavone glucoside tricetin 4'-O-β-glucopyranoside (1) and four known ellagitannins and flavones tricetin (2), luteolin (3), ellagic acid (4), and granatin B (5) were isolated from the flowers of Punica granatum L. (Lythraceae). Their structures were established by 1D and 2D NMR as well as mass spectrometry analyses. Among all tested compounds, tricetin (2) exhibited the strongest α-glucosidase inhibitory activity that was comparable to the anti-diabetic drug acarbose. Comparative structure-function analysis of tri-, tetra-, and pentahydroxy flavones [apigenin, luteolin (3), and tricetin (2), respectively] suggested that a greater number of hydroxyl groups on the flavone molecule enhanced its suppression of α-glucosidase, α-amylase, and lipase activities.

    This study evaluates the safety and efficacy of Punica granatum var pleniflora mouthwash in treatment of diabetic gingivitis. In a double-blind randomized clinical trial 80 patients with diabetes mellitus and gingivitis were assigned to Golnaar and chlorhexidine 0.2% groups. After using mouthwashes for 2 weeks; participants underwent tooth scaling and the last visit was 2 weeks after scaling. The primary outcome measures were plaque, modified gingival and gingival bleeding indices, and pocket depth. Both interventions had significant improvement on all of the gingival and plaque indices (P < .001 for all indices). There were no significant differences between Golnaar and chlorhexidine in primary outcome measures except for modified gingival index for which Golnaar mouthwash had a superiority after 2 weeks when comparing with chlorhexidine (P = .039). Meanwhile, Golnaar mouthwash had no staining effect. Golnaar mouthwash is safe and effective in treatment of gingivitis in diabetic patients although further studies are recommended. © The Author(s) 2016.

    Full Text Available Introduction: Pomegranate (Punica granatum L. belong to Punicaceae family is native to Iran and grown extensively in arid and semi-arid regions worldwide. Pomegranate is also important in human medicine and its components have a wide range of clinical applications. Cracking causes a major fruit loss, which is a serious commercial loss to farmers. Fruit cracking, seems to be a problem that lessens the marketability to a great extent. Fruit cracking is one of the physiological disorders wherever pomegranate trees are grown. It may be due to moisture imbalances as this fruit is very sensitive to variation in soil moisture prolonged drought causes hardening of skin and if this is followed by heavy irrigation the pulp grows then skin grows and cracks. Many factors i.e., climate, soil and irrigation, varieties, pruning, insects and nutrition statues influence the growth and production of fruit trees. Deficiencies of various nutrients are related to soil types, plants and even to various cultivars. Most nutrients are readily fixed in soil having different PH. Plant roots are unable to absorb these nutrients adequately from the dry topsoil. Foliar fertilization is particularly useful under conditions where the absorption of nutrients through the soil and this difficult situation to be present in the nutrients such as calcium. Since the calcium element is needed, so spraying them at the right time is correct way to save the plant requirements. Therefore, a research conducted on effect of sodium chloride concentrations and its foliar application time on quantitative and qualitative characteristics of pomegranate fruit (Punica granatum L. CV. “Malas Saveh”. Materials and Methods: An experiment conducted at Jarghoyeh, Esfahan, Iran in 2012. The factors were Sodium chloride (0, 5 and 10 g/L and times of spray (15, 45 and 75 days before harvest.

    Striae distensae are a frequent skin condition associated with pregnancy, weight change or lack of skin elasticity. The aim of this research was to obtain a topical product containing herbal active ingredients with documented antioxidant and anti-inflammatory activity ( Punica granatum seed oil and Croton lechleri resin extract) and demonstrate its positive effect on prevention and treatment of striae distensae. First, the cream base formulation was optimized through experimental design. Secondly, the cream containing the two active ingredients was investigated in an interventional nonrandomized clinical trial. The clinical outcome was assessed through biophysical parameters and ultrasonographic evaluation. The state of the skin was evaluated by biophysical measurements and ultrasonography at the beginning of the study and after 3 and 6 weeks. The experimental design was successfully used to set the best ranges for the technological and formulation factors to obtain a cosmetic formulation with optimal characteristics. The study of clinical efficacy on the optimal formulation revealed an increase in the dermis thickness, hydration and elasticity values in both groups after 6 weeks of cream application. The new oil-in-water cream containing P. granatum seed oil and C. lechleri resin extract can be helpful in the prevention or improving of skin changes associated with striae.

    Herpes simplex virus - 2 (HSV-2) causes lifelong persisting infection in the immunocompromised host and intermittent in healthy individuals with high morbidity in neonatals and also increase the transmission of HIV. Acyclovir is widely used drug to treat HSV-2 infection but it unable to control viral latency and recurrent infection and prolonged usage lead to drug resistance. Plant-based bioactive compounds are the lead structural bio-molecules play an inevitable role as a potential antiviral agent with reduced toxicity. Therefore, there is an urgent need to develop anti-HSV-2 bioactive molecules to prevent viral resistance and control of latent infection. Punica granatum fruit is rich in major bioactive compounds with potential antimicrobial properties. Hence, we evaluated the anti-HSV-2 efficacy of lyophilized extracts and bioactive compounds isolated from fruit peel of P. granatum. As a result, ethanolic peel extract showed significant inhibition at 62.5 μg/ml. Hence, the fruit peel ethanolic extract was subjected for the isolation of bioactive compounds isolation by bioactivity-guided fractionation. Among isolated bioactive compounds, punicalagin showed 100% anti-HSV-2 activity at 31.25 μg/ml with supportive evidence of desirable in silico ADMET properties and strong interactions to selected protein targets of HSV-2 by docking analysis.

    Anthocyanins are the major pigments responsible for the pomegranate (Punica granatum L.) fruit skin color. The high variability in fruit external color in pomegranate cultivars reflects variations in anthocyanin composition. To identify genes involved in the regulation of anthocyanin biosynthesis pathway in the pomegranate fruit skin we have isolated, expressed and characterized the pomegranate homologue of the Arabidopsis thaliana TRANSPARENT TESTA GLABRA1 (TTG1), encoding a WD40-repeat protein. The TTG1 protein is a regulator of anthocyanins and proanthocyanidins (PAs) biosynthesis in Arabidopsis, and acts by the formation of a transcriptional regulatory complex with two other regulatory proteins: bHLH and MYB. Our results reveal that the pomegranate gene, designated PgWD40, recovered the anthocyanin, PAs, trichome and seed coat mucilage phenotype in Arabidopsis ttg1 mutant. PgWD40 expression and anthocyanin composition in the skin were analyzed during pomegranate fruit development, in two accessions that differ in skin color intensity and timing of appearance. The results indicate high positive correlation between the total cyanidin derivatives quantity (red pigments) and the expression level of PgWD40. Furthermore, strong correlation was found between the steady state levels of PgWD40 transcripts and the transcripts of pomegranate homologues of the structural genes PgDFR and PgLDOX. PgWD40, PgDFR and PgLDOX expression also correlated with the expression of pomegranate homologues of the regulatory genes PgAn1 (bHLH) and PgAn2 (MYB). On the basis of our results we propose that PgWD40 is involved in the regulation of anthocyanin biosynthesis during pomegranate fruit development and that expression of PgWD40, PgAn1 and PgAn2 in the pomegranate fruit skin is required to regulate the expression of downstream structural genes involved in the anthocyanin biosynthesis.

    Punica granatum L. (Punicaceae) peel is often considered as a food waste in-spite of its high bioactive metabolite composition. Primarily it is rich in therapeutically active phenolics that act on multiple cellular sites, through diverse mechanisms. Hence, the present study was envisaged to investigate the effect of standardised peel extract of P. granatum against isoproterenol (ISO)-induced myocardial infarction (MI). ISO administration at a dose of 150 mg/kg; s.c., twice at 24 h interval resulted in electrocardiographic abnormalities with increased heart weight and myocardial tissue damage signifying MI. Pretreatment with the extract at 50, 100 and 200 mg/kg; p.o., for 21 days prior to ISO intoxication (30 min prior to intoxication on day 22 and 23) attenuated the observed changes, along with increased myocardial tissue superoxide dismutase activity, reduced glutathione and nitrite levels, and decreased lipid peroxidation. The extract treated groups also showed reduced serum marker enzymes of MI, showing maximum effect at highest tested dose. Immunohistochemical studies revealed increased myocardial expression of nuclear factor erythroid 2-related factor 2 (Nrf2), endothelial nitric oxide synthase (eNOS) and Bcl-2 proteins in the extract treated groups with decreased Bax expression. From the results it can be concluded that the extract pretreatment prevents ISO-induced MI through increased myocardial expression of eNOS, leading to nitric oxide-mediated Nrf2 activation, thus upregulating antioxidant mechanisms, along with inhibition of apoptosis.

    This study first time reports the novel synthesis of silver nanoparticles (AgNPs) using a Punica granatum leaf extract (PGE). The synthesized AgNPs were characterized by various analytical techniques including UV-Vis, Fourier transform infrared (FTIR), X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy and energy-dispersive spectra (FESEM-EDS) and high-resolution transmission electron microscopy (HRTEM). FTIR analysis revealed that the involvement of biological macromolecules of P. granatum leaf extract were distributed and involved in the synthesis and stabilization of AgNPs. A surface-sensitive technique of XPS was used to analyse the composition and oxidation state of synthesized AgNPs. The analytical results confirmed that the AgNPs were crystalline in nature with spherical shape. The zeta potential study revealed that the surface charge of synthesized AgNPs was highly negative (-26.6 mV) and particle size distribution was ranging from ∼35 to 60 nm and the average particle size was about 48 nm determined by dynamic light scattering (DLS). The PGE-AgNPs antidiabetic potential exhibited effective inhibition against α-amylase and α-glucosidase (IC 50 ; 65.2 and 53.8 μg/mL, respectively). The PGE-AgNPs showed a dose-dependent response against human liver cancer cells (HepG2) (IC 50 ; 70 μg/mL) indicating its greater efficacy in killing cancer cells. They also possessed in vitro free radical-scavenging activity in terms of ABTS (IC 50 ; 52.2 μg/mL) and DPPH (IC 50 ; 67.1 μg/mL) antioxidant activity. PGE-AgNPs displayed strong antibacterial activity and potent synergy with standard antibiotics against pathogenic bacteria. Thus, synthesized PGE-AgNPs show potential biomedical and industrial applications.

    Most conventional treatments on non-small cell lung carcinoma always accompany with awful side effects, and the incidence and mortality rates of this cancer are increasing rapidly worldwide. The objective of this study was to examine the anticancer effects of extract of Punica granatum (pomegranate) leaves extract (PLE) on the non-small cell lung carcinoma cell line A549, H1299 and mouse Lewis lung carcinoma cell line LL/2 in vitro, and explore its mechanisms of action. Our results have shown that PLE inhibited cell proliferation in non-small cell lung carcinoma cell line in a concentration- and time-dependent manner. Flow cytometry (FCM) assay showed that PLE affected H1299 cell survival by arresting cell cycle progression in G2/M phase in a dose-dependent manner and inducing apoptosis. Moreover, PLE could also decrease the reactive oxygen species (ROS) and the mitochondrial membrane potential (ΔYm), indicating that PLE may induce apoptosis via mitochondria-mediated apoptotic pathway. Furthermore, PLE blocked H1299 cell migration and invasion, and the reduction of matrix metalloproteinase (MMP) MMP-2 and MMP-9 expression were also observed in vitro. These results suggested that PLE could be an effective and safe chemotherapeutic agent in non-small cell lung carcinoma treatment by inhibiting proliferation, inducing apoptosis, cell cycle arrest and impairing cell migration and invasion.

    Here we evaluated the effect of fermented milk supplemented with whey protein (approximately 80 % protein), probiotic (Bifidobacterium animalis subsp. lactis BB12) and pomegranate juice (Punica granatum L.) on the physical performance, intestinal motility and villi structure, inflammatory markers and intestinal microbiota of rats under high-intensity acute exercise. In all, twenty-four Wistar rats were separated into groups: control (Ctrl), supplemented (Supp), exercised (Exe) and exercised and supplemented (Exe+Supp). Rats in the Supp groups received fermented milk during 6 weeks by oral administration. At the end of the supplementation period, the Exe groups were submitted to high-intensity acute exercise on a treadmill. We found that intense acute exercise caused changes in the intestinal villi interspace, changes in the proportion of Lactobacillus species and an increase in Clostridium species, as well as a decrease in intestinal motility. Supplementation increased intestinal motility, and maintained the intestinal villi interspace and the natural microbiota proportions of the exercised rats. Physical performance was not improved by fermented milk supplementation. We conclude that the fermented milk containing whey protein, B. animalis (BB12) and pomegranate juice can re-establish intestinal microbiota and protect the animals from the undesirable effects of intense acute exercise.

    Ethanolic crude extracts prepared from the arils and seeds, pericarp, peels and from the whole fruit of Punica granatum, known as pomegranate, had their antifungal activity tested against Candida spp. The ethanolic crude extracts were analyzed by Mass Spectrometry and yielded many compounds such as punicalagin and galladydilacton. The extracts from the pericarp and peel showed activity against Candida spp., with MICs of 125 μg/mL. The effect of pericarp and peel extracts upon the morphological and structure of C. albicans and C. krusei were examined by scanning and transmission electron microscopy, with the visualization of an irregular membrane and hyphae, formation of vacuoles and thickening of the cell wall. The data obtained revealed potential antimicrobial activity against yeasts cells of the Candida genus, and the bioactive compounds could be responsible for changes in cell morphology and structure. The data obtained open new perspectives for future research in continuation to this study, where information such as determination of the site of action of the compounds could contribute to an alternative therapy against these organisms.

    Full Text Available In this work, we characterized conjugated linolenic acids (e.g., punicic acid as the major components of the hydrophilic fraction (80% aqueous methanol extract from pomegranate (Punica granatum L. seed oil (PSO and evaluated their anti-inflammatory potential on some human colon (HT29 and HCT116, liver (HepG2 and Huh7, breast (MCF-7 and MDA-MB-231 and prostate (DU145 cancer lines. Our results demonstrated that punicic acid and its congeners induce a significant decrease of cell viability for two breast cell lines with a related increase of the cell cycle G0/G1 phase respect to untreated cells. Moreover, the evaluation of a great panel of cytokines expressed by MCF-7 and MDA-MB-231 cells showed that the levels of VEGF and nine pro-inflammatory cytokines (IL-2, IL-6, IL-12, IL-17, IP-10, MIP-1α, MIP-1β, MCP-1 and TNF-α decreased in a dose dependent way with increasing amounts of the hydrophilic extracts of PSO, supporting the evidence of an anti-inflammatory effect. Taken together, the data herein suggest a potential synergistic cytotoxic, anti-inflammatory and anti-oxidant role of the polar compounds from PSO.

    The main aim of the present study is to extract and characterize cashew nut shell (CNS) starch and walnut shell cellulose (WNC) for development of cellulose reinforced starch films. Moreover, the extraction and characterization of pomegranate peel extract, for incorporation with CNS-WNC films, was investigated. CNS starch was examined to be a moderate amylose starch with 26.32 ± 0.43% amylose content. Thermal degradation temperature of CNS starch was found to be 310 °C. Walnut shell cellulose was found to have high crystallinity index of 72%, with two thermal degradation temperatures of 319 °C and 461 °C. 2% WN cellulose reinforced CNS starch films were examined to have good oxygen transfer rate, mechanical and physical properties. Thermal degradation temperature of CNS-WNC starch films were found to be at the range of 298-302 °C. Surface roughness of CNS-WNC starch films were found to be increasing with increase in concentration of cellulose in films. Hydroxymethylfurfurole, Benzene, 2-methoxy-1,3,4-trimethyl and 1,2,3-Propanetriol, 1-acetate were found to be major active compounds present in hydrophilic extracts of Punica granatum peels. 2% WN cellulose reinforced starch films infused with hydrophilic active compounds of pomegranate peel was examined to be having good active package properties.

    The main purpose of the present study is to evaluate the ability of nanoemulsion entrapping pomegranate peel polyphenol-rich ethyl acetate fraction (EAF) prepared from pomegranate seed oil and medium chain triglyceride to protect human erythrocyte membrane from oxidative damage and to assess preliminary in vitro photosafety. In order to evaluate the phototoxic effect of nanoemulsions, human red blood cells (RBCs) are used as a biological model and the rate of haemolysis and photohaemolysis (5 J cm(-2) UVA) is assessed in vitro. The level of protection against oxidative damage caused by the peroxyl radical generator AAPH in human RBCs as well as its effects on bilayer membrane characteristics such as fluidity, protein profile and RBCs morphology are determined. EAF-loaded nanoemulsions do not promote haemolysis or photohaemolysis. Anisotropy measurements show that nanoemulsions significantly retrain the increase in membrane fluidity caused by AAPH. SDS-PAGE analysis reveals that AAPH induced degradation of membrane proteins, but that nanoemulsions reduce the extension of degradation. Scanning electron microscopy examinations corroborate the interaction between AAPH, nanoemulsions and the RBC membrane bilayer. Our work demonstrates that Punica granatum nanoemulsions are photosafe and protect RBCs against oxidative damage and possible disturbance of the lipid bilayer of biomembranes. Moreover it suggests that these nanoemulsions could be promising new topical products to reduce the effects of sunlight on skin. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Candida biofilms adhere to the internal surface of removable dentures, which is an etiological factor in the pathogenesis of denture stomatitis (DS). Adhesive materials are used at the base of maxillary complete dentures to improve their retention and chewing qualities. This article reports the antimicrobial activity of the enriched fractions of Equisetum giganteum and Punica granatum incorporated into a denture adhesive against C. albicans biofilm. The biofilms were induced on the surface of heat-cured acrylic resin specimens that were previously treated with a mixture of adhesive/herb extracts. The antimicrobial activity was evaluated by CFU counts, XTT reduction, and SEM and CLSM analysis. Both herb extracts amplified the anti-biofilm action of the adhesive on the acrylic resin by up to 12 h. Therefore, when these extracts were combined with COREGA®, they played a collaborative and innovative role in biofilm control and can be considered alternatives for temporary use in the treatment and/or prevention of DS.

    Essential oils and volatile components of pomegranate ( Punica granatum L.) peel of the Malas variety from Meybod, Iran, were extracted using supercritical fluid extraction (SFE) and hydro-distillation methods. The experimental parameters of SFE that is pressure, temperature, extraction time, and modifier (methanol) volume were optimized using a central composite design after a (2 4-1 ) fractional factorial design. Detailed chemical composition of the essential oils and volatile components obtained by hydro-distillation and optimum condition of the supercritical CO 2 extraction were analyzed by GC-MS, and seventy-three and forty-six compounds were identified according to their retention indices and mass spectra, respectively. The optimum SFE conditions were 350 atm pressure, 55 °C temperature, 30 min extraction time, and 150 µL methanol. Results showed that oleic acid, palmitic acid and (-)-Borneol were major compounds in both extracts. The optimum extraction yield was 1.18 % (w/w) for SFE and 0.21 % (v/w) for hydro-distillation.

    Medicinal plants are rich source of traditional herbal medicine around the globe. Most of the plant's therapeutic properties are due to the presence of secondary bioactive compounds. The present study analyzed the High Pressure Liquid Chromatography (HPLC) fractions of Puncia granatum (peel) extracts (aqueous, chloroform, ethanol and hexane) against multidrug resistant bacterial pathogens (Acinetobacter baumannii, Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus). All the fractions having antibacterial activity was processed for bioactive compounds identification using LC MS/MS analysis. Among total HPLC fractions (n = 30), 4 HPLC fractions of P. granatum (peel) showed potential activity against MDR pathogens. Fraction 1 (F1) and fraction 4 (F4) collected from aqueous extract showed maximum activity against P. aeruginosa. Fraction 2 (F2) of hexane showed antibacterial activity against three pathogens, while ethanol F4 exhibited antibacterial activity against A. baumannii. The active fractions were processed for LC MS/MS analysis to identify bioactive compounds. Valoneic acid dilactone (aqueous F1 and F4), Hexoside (ethanol F4) and Coumaric acid (hexane F2) were identified as bioactive compounds in HPLC fractions. Puncia granatum peel extracts HPLC fractions exhibited potential inhibitory activity against MDR bacterial human pathogens. Several bioactive compounds were identified from the HPLC fractions. Further characterization of these compounds may be helpful to conclude it as therapeutic lead molecules against MDR pathogens.

    Radiation therapy has been used in cancer treatment for many decades; Although effective in killing tumor cells, ROS produced in radiotherapy threaten the integrity and survival of surrounding normal cells. ROS are scavenged by radioprotectors before they can interact with biochemical molecules, thus reducing harmful effects of radiation. The pomegranate, Punica granatum L., an ancient, mystical, and highly distinctive fruit, is the predominant member of the Punicaceae family. It is used in several systems of medicine for a variety of ailments. The objective of the present study was to investigate the protective effects of ethanolic extracts of pomegranate whole fruit (EPWF) and seeds (EPS) and Synthetic Ellagic acid (EA) against Electron Beam Radiation (EBR) induced DNA damage and biochemical alterations in Swiss Albino mice. The extracts and synthetic compound were assessed for its radical scavenging property by DPPH radical scavenging and Ferric Reducing Antioxidant Power assays. The animals were treated with 200 mg/kg body wt. of pomegranate extracts and Ellagic acid for 15 days before exposure to 6 Gy of EBR. Radiation induced DNA damage was assessed by comet assay in the peripheral blood lymphocytes of mice. The biochemical estimations were carried out in the serum and RBC lysate of the animals. The plant extracts and synthetic compound exhibited good radical scavenging and reducing properties.The pretreated animals before irradiation caused a reduction in the comet length, olive tail moment, % DNA in tail when compared to irradiated group. The biochemical parameters such as lipid peroxidation was significantly depleted in the treated groups when compared to irradiated group followed by significant elevation in reduced glutathione. Our findings indicate the ameliorating effects of pomegranate extracts and synthetic ellagic acid on radiation induced DNA damage and biochemical changes in mice may be due to its free radical scavenging and increased antioxidant

    The present study was aimed at the development of a new analytical method for the comprehensive multi-component analysis of polyphenols in Punica granatum L. (pomegranate) juice and peel. While pomegranate juice was directly analysed after simple centrifugation, different extraction techniques, including maceration, heat reflux extraction, ultrasound-assisted extraction and microwave-assisted extraction, were compared in order to obtain a high yield of the target analytes from pomegranate peel. Dynamic maceration with a mixture of water and ethanol 80:20 (v/v) with 0.1% of hydrochloric acid as the extraction solvent provided the best result in terms of recovery of pomegranate secondary metabolites. The quali- and quantitative analysis of pomegranate polyphenols was performed by high-performance liquid chromatography with diode array and electrospray ionization-mass spectrometry detection. The application of fused-core column technology allowed us to obtain an improvement of the chromatographic performance in comparison with that of conventional particulate stationary phases, thus enabling a good separation of all constituents in a shorter time and with low solvent usage. The analytical method was completely validated to show compliance with the International Conference on Harmonization of Technical Requirements for the Registration of Pharmaceuticals for Human Use guidelines and successfully applied to the characterisation of commercial and experimental pomegranate samples, thus demonstrating its efficiency as a tool for the fingerprinting of this plant material. The quantitative data collected were submitted to principal component analysis, in order to highlight the possible presence of pomegranate samples with high content of secondary metabolites. From the statistical analysis, four experimental samples showed a notable content of bioactive compounds in the peels, while commercial ones still represent the best source of healthy juice.

    The pomegranate (Punica granatum) sarcotesta contains a chitin-binding lectin (PgTeL) with antibacterial activity against human pathogenic species. In this work, the structural stability of PgTeL was evaluated by fluorimetric analysis and the lectin was evaluated for cytotoxicity to human peripheral blood mononuclear cells (PBMCs) and antifungal activity against Candida albicans and Candida krusei. PgTeL folding was impaired when lectin was incubated at pH≥6.0. On the other hand, the lectin did not undergo unfolding even when heated at 100°C. PgTeL (1, 10, and 100μg/mL) was not cytotoxic to PBMCs. Antifungal activity was detected for C. albicans (MIC: 25μg/mL; MFC: 50μg/mL) and C. krusei (MIC and MFC of 12.5μg/mL). Treatment of yeast cells with PgTeL resulted in decrease of intracellular ATP content even at sub-inhibitory concentrations (½MIC and ¼MIC) and induced lipid peroxidation. In addition, PgTeL damaged the integrity of fungal cell wall of both species, with more pronounced effects in C. krusei. The lectin showed significant antibiofilm activity on C. albicans at sub-inhibitory concentrations (0.195 and 0.39μg/mL). In conclusion, PgTeL is an anti-Candida agent whose action mechanism involves oxidative stress, energetic collapse, damage to the cell wall and rupture of yeast cells. Copyright © 2017 Elsevier B.V.

    Background This study investigated the effect of Punica granatum L. (pomegranate) juice on the rabbit basilar artery in an experimental subarachnoid hemorrhage (SAH) model. Methods  Eighteen adult male New Zealand white rabbits were randomly divided into three groups: a control group ( n  = 6), SAH group ( n  = 6), and SAH + treatment group ( n  = 6). Basilar artery diameter was measured with magnetic resonance angiography (MRA) in all groups at the beginning of the study. Experimental SAH was created by injecting autologous arterial blood into the cisterna magna. In the treatment group, the subjects were administered a daily dose of 30 ml/kg pomegranate juice via gastric gavage for 4 days after the SAH. The SAH group and SAH + treatment group underwent cerebral MRA after 72 hours. After a neurologic score assessment, all the animals were killed. The wall thickness and lumen area of the basilar artery were measured histometrically in all groups, and the apoptotic cell percentage in the artery was identified. The mean diameter of the basilar artery during MRA was measured. Results  Pomegranate improved neurologic functions compared with the SAH group ( p   0.05). The apoptotic cell rate in the SAH + treatment group was significantly lower than in the SAH group ( p   0.05). Discussion  Pomegranate was shown to have a vasospasm- attenuating effect on the basilar artery in the rabbit SAH model for the first time in our study. Georg Thieme Verlag KG Stuttgart · New York.

    Peel extracts from Citrus sinensis, Punica granatum, and Musa paradisiaca were investigated for their effects on tissue lipid peroxidation (LPO) and on the concentration of thyroid hormones, insulin, and glucose in male rats. In vitro inhibition of H(2)O(2)-induced LPO in red blood cells of rats by 0.25, 0.50, 1.0, and 2.0 microg/mL C. sinensis, P. granatum, and M. paradisiaca peel extracts was observed in a dose-specific manner. Maximum inhibition was observed at 0.50 microg/mL C. sinensis, 2.0 microg/mL P. granatum, and 1.0 microg/mL M. paradisiaca. In the in vivo investigation, out of four different concentrations of each peel extract, 25, 200, and 100 mg/kg C. sinensis, P. granatum, and M. paradisiaca, respectively, were found to maximally inhibit hepatic LPO. The most effective doses were further evaluated for effects on serum triiodothyronine (T(3)), thyroxine (T(4)), insulin, and glucose concentrations. C. sinensis exhibited antithyroidal, hypoglycemic, and insulin stimulatory activities, in addition to inhibition of LPO, as it significantly decreased the serum T(4) (P paradisiaca strongly inhibited the serum level of thyroid hormones (P < .01 for both T(3) and T(4)) but increased the level of glucose (P < .05). These findings reveal the hitherto unknown potential of the tested peel extracts in the regulation of thyroid function and glucose metabolism. Besides antiperoxidative activity, C. sinensis extract has antithyroidal, hypoglycemic, and insulin stimulatory properties, which suggest its potential to ameliorate both hyperthyroidism and diabetes mellitus.

    The interesting properties of Gold Nanoparticles (AuNPs) make them attractive for different application fields such as cosmetology, medicine and clinical nanotechnologies. In this work a fast, easy and eco-friendly method for the AuNPs synthesis is proposed by using the Punica Granatum Juice (PGJ) with potential dermatological and cosmetic applications. The AuNPs antioxidant activity, due to the presence of phenols from the juice, and their use as booster for improving the Sun Protection Factor (SPF) in commercial sunscreen formulations, are thus expounded. By using appropriate amounts of PGJ and HAuCl 4 , under mild work conditions, AuNPs with a mean size of 100 ± 40 nm are observed and carefully characterized. Solution pH, temperature, and volume were also changed for optimizing the AuNPs formation and features. The antioxidant activity was studied, by evaluating the AuNP ability of scavenging the radical 2,2-diphenyl-1-picrylhydrazylhydrate (DPPH). This finding was confirmed performing special experiments focused on the reaction between AuNPs and H 2 O 2 , by using suitable probes, such as 4-thiothymidine (S 4 TdR) and Cytochrome-c (Cyt-c). The SPF value was also calculated. The synthetized AuNPs showed a surface plasmon in visible range at 577 nm and resulted stable for long time in aqueous medium, also changing the pH values in the range 2-12. The studied antioxidant activity, confirmed also by performing special experiments with suitable probes, demonstrated the high performance of AuNPs. The AuNP photostability under sun irradiation is also shown. The calculated SPF values were in the range 3-18, related to AuNPs concentration in the range 1.80 × 10 -12 -1.00 × 10 -11  M. The same AuNPs concentrations were used for cellular experiments. Indeed, since the AuNPs-PGJ mediated will be potentially introduced by dermal contact, dermal fibroblasts (Human Dermal Fibroblasts, HDF) and Human Microvascular Endothelial Cells (HMVEC) were used to

    There has been an increase in the use of botanicals as skin photoprotective agents. Pomegranate (Punica granatum L.) is well known for its high concentration of polyphenolic compounds and for its antioxidant and anti-inflammatory properties. The aim of this study was to analyze the photoprotection provided by P. granatum seed oil nanoemulsion entrapping the polyphenol-rich ethyl acetate fraction against UVB-induced DNA damage in the keratinocyte HaCaT cell line. For this purpose, HaCaT cells were pretreated for 1h with nanoemulsions in a serum-free medium and then irradiated with UVB (90-200 mJ/cm(2)) rays. Fluorescence microscopy analysis provided information about the cellular internalization of the nanodroplets. We also determined the in vitro SPF of the nanoemulsions and evaluated their phototoxicity using the 3T3 Neutral Red Uptake Phototoxicity Test. The nanoemulsions were able to protect the cells' DNA against UVB-induced damage in a concentration dependent manner. Nanodroplets were internalized by the cells but a higher proportion was detected along the cell membrane. The SPF obtained (~25) depended on the concentration of the ethyl acetate fraction and pomegranate seed oil in the nanoemulsion. The photoprotective formulations were classified as non-phototoxic. In conclusion, nanoemulsions entrapping the polyphenol-rich ethyl acetate fraction show potential for use as a sunscreen product. Copyright © 2015 Elsevier B.V. All rights reserved.

    Reactive oxygen species (ROS) is an apoptosis inducer in pancreatic β-cells that stimulates p53/p65 mediated microRNA (miR)-145 expression. Punica granatum L. (pomegranate) is an antioxidant fruit that attenuates ROS generation. This study examines the effects of pomegranate fruit aqueous extract (PGE) on the levels of ROS, p53, p65, miR-145, and its target insulin receptor substrate 1 (irs-1) mRNA in Alloxan-diabetic male Wistar rats. In this experimental study, diabetic rats received different doses of PGE. The effects of the PGE polyphenols were examined through a long-term PGE treatment period model, followed by an evaluation of the plasma and tissue contents of free fatty acids (FFAs), triglycerides (TG), and glycogen compared with diabetic controls (DC) and normal controls (NC). We used real-time polymerase chain reaction (PCR) to investigate the modulation of p53, p65, miR-145, and irs-1 expression levels. There was a noticeable reduction in fasting blood glucose (FBG) and ROS generation compared to DC. We observed marked decreases in p53, p65, miR-145 expression levels followed by an elevated level of irs-1, which contributed to improvement in insulin sensitivity. PGE administration downregulated miR-145 levels in Alloxan-diabetic Wistar rats by suppression of ROS-mediated p53 and p65 overexpression. Copyright© by Royan Institute. All rights reserved.

    The influence of the supplementation of pomegranate peel extract containing anthocyanins on atherosclerotic plaque formation induced by hypercholesterolemia was investigated in renal arteries in rabbits. After the determination of polyphenol and anthocyanin's content of P. granatum peel hydroalcoholic extract, 30 male rabbits were randomly divided into three groups. They were fed basic diet, hypercholesterolemic diet and hypercholesterolemic diet along with P. granatum peel extract (polyphenolic content for each rabbit 1 g/kg diet) for 2 month. Blood samples were collected at the begging, middle and end of the study in order to measure lipid concentration and oxidative and antioxidative status variables, and renal arteries were taken for the assessment of atherosclerotic plaques at the end of the study. The results reveal that P. granatum peel extract significantly increases serum antioxidant capacity in the extract recipient group in comparison with hypercholesterolemic control (P 0.05). The results of this study indicate that consumption of pomegranate peel extract containing anthocyanins (polyphenol content 1 g/kg diet) despite of a significant increase in serum antioxidant capacity cannot protect the kidneys from hypercholesterolemia-induced damages during the treatment period.

    Pomegranate fruits are difficult to peel and once peeled, extracted arils have very short shelf-life. Therefore, present investigation was carried out to extend the shelf life of minimally processed pomegranate arils using pectin methyl esterase (PME) and CaCl2 treatment during refrigerated storage. The arils of freshly harvested pomegranate fruits (Punica granatum L.) were treated with different concentrations of food-grade PME (50-300 units) and calcium ions (0.5-2.0% CaCl₂) for a period of 5-30 min using response surface methodology. Treated and untreated arils were then packed in low density polyethylene bags (25 μ) and maintained under low temperature (5°C; 90% RH) for evaluating the physical, biochemical and microbial quality of pomegranate arils at four day interval. Physiological loss in weight increased during storage but no food-borne pathogens were found during 28 day of cold storage in treated arils. Color and firmness of both treated and untreated arils decreased during storage but it was better maintained in treated arils. The firmness was found to be 0.630 N in treated samples compared to untreated one (0.511 N) after 20 d of storage. Total antioxidant capacity, ferric reducing antioxidant power, polyphenol oxidase and lipoxygenase activities increased during storage. Treatment with 249.33 units of PME and 1.70% CaCl₂for an immersion time of 24.93 min was found to be most effective treatment for maintaining the quality of minimally processed arils for longer period. Sensory score was also higher in treated pomegranate arils that were quite acceptable even after 20 day of referigerated storage as against 12 day for untreated ones.

    The extracts derived from pomegranate juice following antioxidant activity directed isolation were screened for their antioxidant activity through their ability to scavenge 2,2- diphenyl-l-picrylhydrazyl (DPPH) radicals. Only fractions which exhibited >50 / 0 DPPH scavenging effect at each step of isolation were selected for further purification and their ability to reduce peroxide formation (peroxide value) in heated com oil. Phytochemical analysis of the pure compounds finally obtained, revealed the presence of pelargonidin-3- galactose (Pg-3-galactose), cyanidin-3-glucose (Cy-3-Glucose), gallic acid, quercetin and myricetin in the fractions exhibiting >50% DPPH scavenging potential. The order of antioxidant activity of these pure compounds by DPPH method was found to be gallic acid> quercetin> myricetin> Cy-3-galactose> Pg-3-Glucose while order with respect to reduction in peroxide value (PV) was the reverse of DPPH.

    Pomegranate (Punica granatum L.) is an important fruit in many cultures. The fruit and juice have risen in popularity as it was discovered that pomegranate has relatively high antioxidant activity compared to most other fruits. In this study, six cultivars were utilized to determine consumer acceptance compared to the industry standard, 'Wonderful,' which comprises 90% to 95% of commercial production in the United States. Fruit were sourced from 2 cultivar field trials, one in inland Riverside, California, and one in coastal Ventura County, California. Cultivars selected for the study included 'Eversweet,' 'Green Globe,' 'Haku Botan,' 'Loffani,' 'Phoenicia,' 'Wonderful,' and 'cv. 857,' an heirloom cultivar from Ventura County, CA, U.S.A. Pomegranate arils were subject to sensory evaluation by 87 untrained consumer panelists in late 2016. Panelists were given pomegranate arils and asked to score the samples using a 9-point Hedonic scale for the following fruit quality traits: aril color, sweetness, tartness, seed hardness, bitterness, and overall desirability. There were significant differences among cultivars for all traits assessed by the sensory panelists. There were differences in acceptance among consumers for 'Wonderful' depending on if it was grown on the coast versus inland, and consumers preferred inland- versus coastal-grown 'Wonderful.' 'Wonderful' pomegranate was associated with cultivars that consumers scored low on desirability for bitterness. Cultivars that scored well in overall desirability compared with 'Wonderful' were 'cv. 857,' 'Eversweet,' 'Green Globe,' and 'Phoenicia.' Consumer sensory panels are important to determine scientifically which cultivars are desired by the public. These panels allowed for the determination of which pomegranate cultivars are liked or disliked by consumers and why. If the pomegranate growers know the most desirable cultivars for consumers, they are more likely to adopt and plant them, thus potentially increasing the

    Full Text Available Background and Aim:The peels of six Iranian pomegranates (Punica granatum L. cultivars, as a traditional medicine, were treated with a new miniaturized matrix solid-phase dispersion (MSPD method for the HPLC determination of ellagic acid (EA. Materials and Methods:In the proposed method, only 10mg of the sample powder was ground and blended with an equal amount of C18 sorbent in an agate mortar. The use of the agate mortar with smooth surface facilitated the sample transfer into a cartridge and reduced the required amount of sample and sorbent. Micro volumes of dichloromethane, n-hexane and methanol were used as modifier, washing and elution solvents, respectively. The eluate was injected into an HPLC-UV system for the analysis. Results:Several factors such as the type and amount of dispersing sorbent, modifier, washing solvent and eluent were carefully studied and optimized. Six replicated analyses at the optimized conditions resulted in a recovery of 96.7% and a relative standard deviation of 5.87%. The proposed method was successfully applied to the extraction and determination of EA in the peels samples. Conclusion:According to the ultimate results, the MSPD method is an efficient technique for the quantitative extraction of EA from the peels of pomegranate. Malas cultivar has the highest amount (18.1 g kg-1 of ellagic acid content compared to the other studied pomegranate cultivars.

    Full Text Available Plant seeds used rely on a wide range of internal mechanisms and physio-chemical factors to ensure their germination under favorable environmental conditions. Most plant seeds have complex process of germination, including water, oxygen, temperature availability, genome-wide gene expression, signal transduction, hormones stimulations, inhibitors removal and catalytic protein synthesis. In addition, influences of seeds nutrient values such as, protein, lipids, sugars and free amino acids have a special importance. Regarding, seeds free amino acids. Discussion of these individual factors needs to be put in context of their role in germination processes. Regarding, free amino acids seed storage, there is limited information about their relevant functions in activation and/or deactivation of required metabolic mechanisms and interactive compounds involved in this process in commercial plant cultivars. Therefore, current study was aimed to determine the probable influence of free amino acid compositions of seeds on germination process of two different (Punica granatum L. pomegranate cultivars including wild type Automi cultivar and edible Khazemi cultivar. In particular, we focused on the impact of amino acids contents variations on germination process and associated AAs compositional changes during various stages of germination and seedlings establishment. Amino acid analysis using HPLC detected all the essential and non-essential amino acids in the raw seeds of the studied cultivars, Automi and Khazemi along with AAs compositional changes occurred during different stages of seed germination. These AAs have been extensively analyzed in the context of their role in dormancy breaking capacities in plants species. Automi raw seeds are rich in Phe, that, is strongly related to ABA synthesis and hence might be responsible for the dormancy of Automi seeds, Khazemi raw seeds have sufficient levels of Arg, Glu and Met that have been reported to enhance

    Pomegranate juice (PGJ) is rich in phenolics which are potent antioxidants but also prone to interact with proteins. A yogurt rich in PGJ (40%) made from arils was elaborated (PGY) to determine the antioxidant activity and to estimate the phenolics-proteins interaction during 28 days of cold storage. Juice, yogurts, and protein-free permeates were analyzed for phenolic composition. Yogurt fermentation modified the anthocyanin profile of the initial PGJ, especially the content in cyanidin-3-O-glucoside. During storage, individual anthocyanin content in PGY decreased but it did not modify yogurt color. The analysis of permeates revealed that the degree of phenol-protein interaction depends on the type of phenolic, ellagic acid and dephinidin-3,5-O-diglucoside being the least bound phenolic compounds. The presence of PGJ in yogurt enhanced radical scavenging performance, whereas all the observed ferric reducing power ability of PGY was strictly due to the PGJ present. The 84.73% of total anthocyanins remained bound to proteins at the first day of storage and 90.06% after 28 days of cold storage, revealing the high affinity of anthocyanins for milk proteins.

    Prostate cancer is a big threat to male for its poor prognosis and high mortality rate. Natural compounds are important resources of many anticancer drugs. Pomegranate is a kind of antioxidant-rich fruit and its peel and seed has potential anticancer activities. In this study, we aimed to investigate the effects of pomegranate peel extract (PoPx) on the apoptosis and metastasis of prostate cancer cells and the related mechanism. We found that PoPx showed growth inhibition on prostate cancer cells. Nuclei morphological and flow cytometer (FCM) analysis indicated that PoPx could induce prostate cancer apoptosis. Further investigation indicated that mitochondrial mediated intrinsic pathway is involved in the apoptosis. Exposure to PoPx led to loss of mitochondrial transmembrane potential (Δym), accumulation of reactive oxygen species (ROS). Western blot analysis showed that PoPx could increase the expression ratio of Bax/Bcl2 and activation of apoptosis executor caspase 3. Wound healing assay and transwell migration and invasion assay implied that PoPx has the potential to inhibit migration and invasion, two critical steps in prostate cancer metastasis. Downregulation of MMP2/MMP9 and upregulation of TIMP2 showed accordance with the inhibition of migration and invasion. In summary, the present data showed that PoPx could be a promising drug candidate to treat prostate cancer, showing us a better way to develop novel drugs from natural compounds.

    Full Text Available The main objectives of this study are to assess crop water stress index (CWSI and to determine irrigation schedule of pomegranate using infrared thermometer technique. Treatments with three replications were irrigated every three and six days intervals, as much as 0.50 (S1, 0.75 (S2, 1.00 (S3, and 1.25 (S4 of Class A pan evaporation. Additionally, an unirrigated plot was also formed. The equations obtained for non-water stress baseline is Tc-Ta=0.645VPD-4.338. The equation of full water stressed upper baseline obtained from data taken from branches of pomegranate plant cut in different days is given by Tc-Ta= 0.0489VPD+2.8734. According to the results obtained, it is concluded that infrared thermometer can be used for irrigation scheduling of the pomegranate plants in Antalya conditions. When using this technique in Antalya conditions, it is suggested to keep the seasonal mean CWSI value approximately 0.12 and the index value of 0.40 can be used to start the irrigation. Additionally, it is suggested that the amount of irrigation can be determined as much as the amount of evaporation measured until the index value reaches 0.40.

    The effectiveness of ultrasonic-assisted extraction (UAE) of pomegranate seed oil (PSO) was evaluated using a variety of solvents. Petroleum ether was the most effective for oil extraction, followed by n-hexane, ethyl acetate, diethyl ether, acetone, and isopropanol. Several variables, such as ultrasonic power, extraction temperature, extraction time, and the ratio of solvent volume and seed weight (S/S ratio) were studied for optimization using response surface methodology (RSM). The highest oil yield, 25.11% (w/w), was obtained using petroleum ether under optimal conditions for ultrasonic power, extraction temperature, extraction time, and S/S ratio at 140 W, 40 °C, 36 min, and 10 ml/g, respectively. The PSO yield extracted by UAE was significantly higher than by using Soxhlet extraction (SE; 20.50%) and supercriti cal fluid extraction (SFE; 15.72%). The fatty acid compositions were significantly different among the PSO extracted by Soxhlet extraction, SFE, and UAE, with punicic acid (>65%) being the most dominant using UAE.

    Full Text Available Background: Prevention of caries as well as periodontal disease is mandatory during orthodontic treatment. Nevertheless, the use of antiseptic mouthrinse is contraindicated for prolonged use. Pomegranate juice is a polyphenol-rich juice with high antioxidant capacity as well as antimicrobial properties. It has been shown to exert beneficial characteristics for orthodontic patients such as antioxidant and anti inflammatory effects. Moreover, it contained fluoride and phosphorous which are cariostatic. Previous study in fixed orthodontic patients revealed that rinsing with this juice showed reduced dental plaque and superior compared with chlorhexidine. If it has unwanted effect by reducing pro-inflammatory reaction that also needed in orthodontic movement is not clearly understood. Purpose: The aim of the present review was to discuss the beneficial and unwanted effect of pomegranate juice mouthrinse towards orthodontic treatment. Reviews: Pomegranate has antimicrobial activity, its methanolic skin extract is the most potent followed by seed juice. Nevertheless, seed juice is not only tastier, easier to make but also has mild antimicrobial potency which is beneficial for long-term use. Healthy periodontal tissue is preferable for orthodontic movement since it resulted in less unwanted bone resorption. Conclusion: Regarding its beneficial effect and safety of pomegranate juice if use daily mouthrinse in fixed orthodontic patients, it could be proposed as an ideal long term use mouthrinse for fixed orthodontic patients. However, further researches should be done to verify this concept.Latar belakang: Pencegahan karies dan penyakit periodontal sangat penting dalam perawatan ortodontik. Walaupun demikian, penggunaan obat kumur antiseptik jangka panjang merupakan kontraindikasi. Jus buah delima sangat kaya akan polifenol dengan kemampuan antioksidan yang tinggi disertai kemampuan antimikroba. Beberapa penelitian telah menunjukkan dampak menguntungkan pada pasien ortodonti, yaitu sebagai antioksidan dan anti radang. Selain itu juga mengandung fluor dan fosfor yang bersifat kariostatik. Penelitian terdahulu pada pasien ortodonti cekat menunjukkan penurunan plak gigi yang lebih banyak dibanding dengan klorheksidin. Akan tetapi, apakah juga menyebabkan dampak merugikan yaitu mengurangi reaksi keradangan yang juga penting bagi pergerakan ortodonti masih belum jelas. Tujuan: Membahas dampak menguntungkan maupun merugikan jus buah delima pada perawatan ortodonti. Tinjauan pustaka: Buah delima merupakan antimikroba, ekstrak dari kulit yang mengandung metanol adalah paling kuat diikuti jus biji delima. Akan tetapi, jus biji lebih enak rasanya, mudah dibuat dan merupakan antimikroba ringan sehingga menguntungkan untuk pemakaian jangka panjang. Jaringan periodontal yang sehat diperlukan untuk pergerakan ortodonti karena dapat mengurangi resorpsi tulang. Kesimpulan: Berdasarkan dampak menguntungkan dan keamanan jus buah delima bila digunakan tiap hari, bahan ini dapat diusulkan sebagai obat kumur jangka panjang yang ideal untuk pasien ortodonti cekat. Walaupun begitu, penelitian lebih lanjut harus dilakukan untuk verifikasi konsep ini.

These properties indicate that pomegranate juice is a suitable storage medium for avulsed teeth. However, this idea has not yet been tested. In this study, the capacity of pomegranate juice (PJ as a storage medium for retaining avulsed teeth was evaluated.PDL fibroblasts were obtained from healthy human premolars and cultured in Dulbecco's Modified Eagle's Medium (DMEM. Cultured cells were subjected to different concentrations of pomegranate juice (PJ, 1% Hank's balanced salt solution (HBSS and tap water for 1, 3, 6 and 24 hours. PDL cell viability was assessed by the neutral red uptake assay.The results indicated that 7.5% PJ was the most effective solution for maintaining PDL cell viability amongst all the experimental solution's and time intervals (P<0.05. The results also showed that 1% PJ was as effective as HBSS for maintaining PDL cell viability. The amount of cell viability increased with increasing concentration of PJ at all time intervals (P<0.001. This effect is suggestive of the proliferative potential of PJ solution.In conclusion, PJ can be recommended as a suitable transport medium for avulsed teeth.

    Full Text Available Abstract Background For ≈ 24 years the AIDS pandemic has claimed ≈ 30 million lives, causing ≈ 14,000 new HIV-1 infections daily worldwide in 2003. About 80% of infections occur by heterosexual transmission. In the absence of vaccines, topical microbicides, expected to block virus transmission, offer hope for controlling the pandemic. Antiretroviral chemotherapeutics have decreased AIDS mortality in industrialized countries, but only minimally in developing countries. To prevent an analogous dichotomy, microbicides should be: acceptable; accessible; affordable; and accelerative in transition from development to marketing. Already marketed pharmaceutical excipients or foods, with established safety records and adequate anti-HIV-1 activity, may provide this option. Methods Fruit juices were screened for inhibitory activity against HIV-1 IIIB using CD4 and CXCR4 as cell receptors. The best juice was tested for inhibition of: (1 infection by HIV-1 BaL, utilizing CCR5 as the cellular coreceptor; and (2 binding of gp120 IIIB and gp120 BaL, respectively, to CXCR4 and CCR5. To remove most colored juice components, the adsorption of the effective ingredient(s to dispersible excipients and other foods was investigated. A selected complex was assayed for inhibition of infection by primary HIV-1 isolates. Results HIV-1 entry inhibitors from pomegranate juice adsorb onto corn starch. The resulting complex blocks virus binding to CD4 and CXCR4/CCR5 and inhibits infection by primary virus clades A to G and group O. Conclusion These results suggest the possibility of producing an anti-HIV-1 microbicide from inexpensive, widely available sources, whose safety has been established throughout centuries, provided that its quality is adequately standardized and monitored.

    Full Text Available Abstract This study aimed to characterize pomegranate seed oil and evaluate its quality and stability parameters against those of linseed oil. The profile of fatty acids and phytosterols and the content of tocopherols were analyzed by gas chromatography and high performance liquid chromatography, respectively. The quality of both oils was assessed as recommended by the American Oil Chemists' Society (AOCS and stability was evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH, β-carotene bleaching (coupled oxidation of β-carotene/linoleic acid and Rancimat® assays. While α-linolenic acid (52% was the most abundant fatty acid in linseed oil (LO, punicic acid (55% was highest in pomegranate seed oil (PSO. Tocopherols and phytosterols (175 and 539 mg/100 g, respectively were greater in PSO than in LO (51 and 328 mg/100 g, respectively. Both oils met quality standards. The β-carotene bleaching and the DPPH assays showed greater oxidative stability for PSO than for LO. The Rancimat® method, on the other hand, indicated low stability for both oils.

    To study protective role of pomegranate extract on radiation induced dermatitis and mucositis in head and neck cancer patients, a prospective, clinical, double blind case control study was carried out. 60 patients (30 active and controls) undergoing radiotherapy for head and neck cancer were studied for 12 months. Patients in study group were given whole fruit pomegranate extract. Each capsule contained 300 mg of whole fruit extract, each capsule contains 40% polyphenols and 27% punicalagin. Each patient was given 2 capsules every day for a period of 6 to 7 weeks. The skin and mucosal changes was graded according to the Acute Radiation Morbidity Scoring criteria (RTOG) for skin and mucous membrane. Among the 30 patients who received the pomegranate extract, 27 had grade 1, 2 had grade 2 and 1 had grade 3 dermatitis. Whereas those who did not receive the extract, 20 had grade 2 dermatitis, 7 had grade 3 dermatitis and 3 had grade 4 dermatitis. Among the 30 patients who received the pomegranate extract, 10 had grade 0, 17 had grade 1 and 3 had grade 2 mucositis. Whereas of those who did not receive the extract, 21 had grade 2 mucositis, 9 had grade 3 mucositis. The results were statistically significant. Our study is one of the first study in humans to demonstrate the effectiveness of pomegranate extract in preventing radiation dermatitis and mucositis. (author)

    Ischemic heart disease is the leading cause of mortality worldwide. The purpose of this study was to evaluate the cardioprotective effects of pomegranate juice in patients with ischemic heart disease. One hundred patients, diagnosed with unstable angina or myocardial infarction, were randomly assigned to the test and the control groups (n = 50, each). During 5 days of hospitalization, in addition to the conventional medical therapies, the test groups received 220 mL pomegranate juice, daily. During the hospitalization period, the blood pressure, heart rate, as well as the intensity, occurrence, and duration of the angina were evaluated on a regular basis. At the end of the hospitalization period, the serum levels of malondialdehyde, interleukin-6, and tumor necrosis factor alpha were measured in all patients. The levels of serum troponin and high-sensitive C-reactive protein levels were also assayed in patients diagnosed with myocardial infarction. Pomegranate juice caused significant reductions in the intensity, occurrence, and duration of angina pectoris in patients with unstable angina. Consistently, the test patients had significantly lower levels of serum troponin and malondialdehyde. Other studied parameters did not change significantly. The results of this study suggest protective effects of pomegranate juice against myocardial ischemia and reperfusion injury. Copyright © 2017 John Wiley & Sons, Ltd.

    Pomegranate juice and related products have long been used either in traditional medicine or as nutritional supplements claiming beneficial effects. Although there are several studies on this food plant, only a few studies have been performed with pomegranate juice or marketed products. The aim of this work is to evaluate the antioxidant effects of pomegranate juice on cellular models using hydrogen peroxide as an oxidizing agent or DPPH and superoxide radicals in cell free systems. The antiproliferative effects of the juice were measured on HeLa and PC-3 cells by the MTT assay and pharmacologically relevant enzymes (cyclooxygenases, xanthine oxidase, acetylcholinesterase and monoamine oxidase A) were selected for enzymatic inhibition assays. Pomegranate juice showed significant protective effects against hydrogen peroxide induced toxicity in the Artemia salina and HepG2 models; these effects may be attributed to radical scavenging properties of pomegranate as the juice was able to reduce DPPH and superoxide radicals. Moderate antiproliferative activities in HeLa and PC-3 cancer cells were observed. However, pomegranate juice was also able to inhibit COX-2 and MAO-A enzymes. This study reveals some mechanisms by which pomegranate juice may have interesting and beneficial effects in human health.

    Multiple myeloma (MM) is a clonal B-cell malignancy characterized by an accumulation of clonal plasma cells (PC) in the bone marrow (BM) leading to bone destruction and BM failure. Despite recent advances in pharmacological therapy, MM remains a largely incurable pathology. Therefore, novel effective and less toxic agents are urgently necessary. In the last few years, pomegranate has been studied for its potential therapeutic properties including treatment and prevention of cancer. Pomegranate juice (PGJ) contains a number of potential active compounds including organic acids, vitamins, sugars, and phenolic components that are all responsible of the pro-apoptotic effects observed in tumor cell line. The aim of present investigation is to assess the antiproliferative and antiangiogenic potential of the PGJ in human multiple myeloma cell lines. Our data demonstrate the anti-proliferative potential of PGJ in MM cells; its ability to induce G0/G1 cell cycle block and its anti-angiogenic effects. Interestingly, sequential combination of bortezomib/PGJ improved the cytotoxic effect of the proteosome inhibitor. We investigated the effect of PGJ on angiogenesis and cell migration/invasion. Interestingly, we observed an inhibitory effect on the tube formation, microvessel outgrowth aorting ring and decreased cell migration and invasion as showed by wound-healing and transwell assays, respectively. Analysis of angiogenic genes expression in endothelial cells confirmed the anti-angiogenic properties of pomegranate. Therefore, PGJ administration could represent a good tool in order to identify novel therapeutic strategies for MM treatment, exploiting its anti-proliferative and anti-angiogenic effects. Finally, the present research supports the evidence that PGJ could play a key role of a future therapeutic approach for treatment of MM in order to optimize the pharmacological effect of bortezomib, especially as adjuvant after treatment.

    Granatum carbon (GC) as electrode materials for supercapacitors is prepared via the chemical activation with different activating agent such as ZnC2 and KOH with an intention to improve the surface area and their electrochemical performance. The structure and electrochemical properties of GC materials are characterized with N2 adsorption/desorption measurements, scanning electron microscope (SEM), cyclic voltammetry (CV), galvanostatic charge/discharge cycling and electrochemical impedance spectroscopy (EIS). The obtained results show that the specific surface area of the granatum-based activated carbons increased obviously from 573 m2 x g(-1) to 1341 m2 x g(-1) by ZnC2 activation and to 930 m2 x g(-1) by KOH treatment. Furthermore, GCZ also delivers specific capacitance of 195.1 Fx g(-1) at the current density of 0.1 A x g(-1) in 30 wt.% KOH aqueous electrolyte and low capacitance loss of 28.5% when the current density increased by 10 times.

    Full Text Available Coccidiosis is the most prevalent disease causing widespread economic loss, especially in poultry farms. Here, we investigated the effects of pomegranate peel extract (PPE on the outcome of coccidiosis caused by Eimeria papillata in mice. The data showed that mice infected with E. papillata and treated with PPE revealed a significant decrease in the output of oocysts in their faeces by day 5 p.i. Infection also induced inflammation and injury of the jejunum. This was evidenced (i as increases in reactive oxygen species, (ii, as increased neutrophils and decreased lymphocytes in blood (ii as increased mRNA levels of inducible nitric oxide synthase (iNOS, Bcl-2 gene, and of the cytokines interferon gamma (IFN-γ, tumour necrosis factor-α (TNF-α, and interleukin-1β (IL-1β, and (iv as downregulation of mucin gene MUC2 mRNA. All these infection-induced parameters were significantly altered during PPE treatment. In particular, PPE counteracted the E. papillata-induced loss of the total antioxidant capacity. Our data indicated that PPE treatment significantly attenuated inflammation and injury of the jejunum induced by E. papillata infections.

    The effect of two extraction methods of pomegranate juice on its quality and stability was evaluated. The first method consisted of separation of the seeds from fruits and centrifugation. The second method consisted of squeezing fruit halves with an electric lemon squeezer. During a period of 72 hours of cold storage at $4^\\circ$ C, the juices were evaluated for the presence of sugars, organic acids, and anthocyanins. Delphinidin 3-glucoside was identified to be the major anthocyanin present at the level of 45-69 mg/L. Among the organic acids, oxalic and tartaric acids dominated. The major sugars detected in pomegranate juice were glucose and sucrose. No significant differences in the content of sugars, organic acids, or anthocyanins in juices obtained through application of the two different extraction methods were detected, with the exception of the drastic decrease of cyanidin $3,5$ -diglucoside level in juice obtained by seed centrifugation. The pH did not show differences between treatments. Titrable acidity and the level of sugars expressed as ${}^{\\circ}$ Brix decreased after 32 and 15 hours after extraction, respectively, when juice was obtained by centrifuging the seeds.

    This study aimed at estimating the consumer's willingness to pay (WTP) more for value-added pomegranate juice using the contingent valuation method (CVM). The WTP was estimated applying the open-ended elicitation technique with 454 consumers in two supermarkets located in Rio de Janeiro, Brazil. The average consumer's WTP more for pomegranate juice was estimated in R$2.04 (Brazilian currency) and the income elasticity coefficient at the midpoint was 0.19, i.e., a 10% increase in consumer income will increase, on average, 1.9% the WTP of pomegranate juice (ceteris paribus). Therefore, the income elasticity coefficient was considered inelastic, once an increase in income would have low effect on the WTP for these consumers. The results indicated that the consumers were interested in acquiring a non-traditional juice processed using a technology that preserves vitamins and antioxidants, maintains the flavor of "fresh juice" without colorants and preservatives, despite the pomegranate is not part of the Brazilian diet.

    Functional properties (anthocyanins, antioxidant, ascorbic acid and tannin) and sensory score were determined in pomegranate fruits at two storage temperatures (3 and 5 °C) after treatment with 2 mM putrescine and 1 : 10 carnauba wax (carnauba wax : water). The treatments (putrescine and carnauba wax) were given by immersion method followed by storage up to 60 days. Both treatments retained significantly higher anthocyanins, antioxidant, ascorbic acid, tannin and sensory qualities as compared with control fruits under both the storage conditions. Combined application of putrescine + carnauba wax showed better response in retaining functional properties than putrescine treated or nontreated fruits. The impacts of putrescine and carnauba wax treatments were found more pronounced after 30 days at 3-5 °C storage temperature in retaining functional and sensory qualities. After 60 days of storage, putrescine + carnauba wax retained about 25% higher antioxidant activity both at 3 and 5 °C storage temperatures.

    The effect of three different coatings; resin wax (Britex Ti), carnauba wax (Xedasol M14), and chitosan (1 and 2 % w/v) on postharvest quality of pomegranate fruits were investigated. Fruits quality characteristics and bioactive compounds were evaluated during 40, 80 and 120 days storage at 4.5 °C and 3 additional days at 20 °C. The results showed that uncoated fruits showed higher respiration rate, weight loss, L* and b* values of arils, total soluble solids (TSS)/titratable acidity (TA), and pH than coated fruits during storage. Coating treatments could delay declining TSS and TA percent, a* value of arils, as well as bioactive compounds such as total phenolics, flavonoids and anthocyanins content and antioxidant activity. The coated fruits with commercial resin and carnauba waxes showed significantly lower respiration rate and weight loss than other treatments, however carnauba wax could maintain considerably higher fruits quality and bioactive compounds than other coating treatments. The results suggested that postharvest application of carnauba wax have a potential to extend storage life of pomegranate fruits by reducing respiration rate, water loss and maintaining fruit quality.

    Hui Yang

    Full Text Available Nano-silver and its composite materials are widely used in medicine, food and other industries due to their strong conductivity, size effect and other special performances. So far, more microbial researches have been applied, but a plant method is rarely reported. In order to open up a new way to prepare AgNP composites, pomegranate peel extract was used in this work to reduce Ag+ to prepare Ag/Ag+/Ag3+ nanoparticle composites. UV–Vis was employed to detect and track the reduction of Ag+ and the forming process of AgNPs. The composition, structure and size of the crystal were analyzed by XRD and TEM. Results showed that, under mild conditions, pomegranate peel extract reacted with dilute AgNO3 solution to produce Ag/Ag+/Ag3+ nanoparticle composites. At pH = 8 and 10 mmol/L of AgNO3 concentration, the size of the achieved composites ranged between 15 and 35 nm with spherical shapes and good crystallinity. The bactericidal experiment indicated that the prepared Ag/Ag+/Ag3+ nanoparticles had strong antibacterial activity against gram positive bacteria and gram negative bacteria. FTIR analysis revealed that biological macromolecules with groups of NH2, OH, and others were distributed on the surface of the newly synthesized Ag/Ag+/Ag3+ nanoparticles. This provided a useful clue to further study the AgNP biosynthesis mechanism. Keywords: Pomegranate rind, Biosynthesis, Ag/Ag+/Ag3+ nanoparticle composites, Antibacterial activity

    Full Text Available Tunisian pomegranate Hop stunt viroid (HSVd variants are described. Dot-blot hybridization, S-Page, and reverse transcription polymerase chain reaction (RT-PCR of RNA extracts from infected tissues were carried out. Results obtained by these techniques were confirmed by cDNA sequencing. The genetic diversity among the Tunisian variants was investigated, which also involved analysis of sequences of previously described HSVd variants from Tunisian citrus var. clementine and fig, and from fruit trees from other Mediterranean countries. Phylogenetic analysis showed that Tunisian pomegranate HSVd variants were clustered into two groups: a cachexia strain within the citrus type group and a recombinant citrus-plum type group. Results also showed a high haplotype diversity which was not related either to the host or to the geographical origin. Selective neutrality and genetic network tests suggest that the HSVd isolates have spread rapidly.

    Full Text Available Most recently, green synthesis of metal oxide nanoparticles has become an interesting subject of the nanoscience and nanotechnology. The use of plant systems has been deemed a green route and a dependable method for nanoparticle biosynthesis, owing to its environmental friendly nature. The present work demonstrates the bioreductive green synthesis of nanosized zinc oxide (ZnO using peel extracts of pomegranate. Highly crystalline ZnO nanoparticles (ZnO NPs which are 5 nm in particle size were characterised by HRTEM and XRD. FT-IR spectra confirmed the presence of the biomolecules and formation of plant protein-coated ZnO NPs and also the pure ZnO NPs. Electrochemical investigation revealed the redox properties and the conductivity of the as-prepared ZnO nanoparticles. The optical band gap of ZnO NPs was calculated to be 3.48 eV which indicates that ZnO NPs can be used in metal oxide semiconductor-based devices. Further, the nanomaterials were also found to be good inhibitors of bacterial strains at both low and high concentrations of 5–10 mg mL−1.

    Highlights: ► Pomegranate leaf extracts mediated rapid gold nanoparticle (AuNP) synthesis. ► The phyto-inspired AuNPs were size-tuned and characterized. ► The reducing and capping agents in the extract were identified. ► The nanoparticles reacted specifically with arsenate (V) ions. - Abstract: When pomegranate leaf extracts were incubated with chloroauric acid (HAuCl{sub 4}), gold nanoparticles (AuNPs) were synthesized. These were characterized by a variety of techniques. With an increasing content of the leaf extract, a gradual decrease in size and an increase in monodispersity were observed. Transmission electron microscope (TEM) images showed that the phyto-fabricated AuNPs were surrounded by an amorphous layer. Gallic acid in the extract mediated the reduction and a natural decapeptide capped the nanostructures. Blocking of thiol groups in the decapeptide cysteine residues caused the nanoparticles to aggregate. On interaction with arsenate (V) ions, the UV–vis spectra of the nanoparticles showed a decrease in intensity and a red-shift. Energy dispersive spectra confirmed the presence of arsenate associated with the AuNPs. Thus, by using these AuNPs, a method for sensing the toxic arsenate ions could be developed.

    Pomegranate allergy is associated with sensitization to non-specific lipid transfer proteins (nsLTPs). Our aim was to identify and characterize the non-specific nsLTPs expressed in pomegranate at the molecular level and to study their allergenic properties in terms of immunoglobulin E (IgE)-binding and cross-reactivity with peach nsLTP (Pru p 3). A non-equilibrium two-dimensional (2-D) electrophoretic approach based on acid-urea PAGE and sodium dodecyl sulfate PAGE was set up to separate pomegranate nsLTPs. Their immunoreactivity was tested by immunoblotting carried out with anti-Pru p 3 polyclonal antibodies and sera from pomegranate-allergic patients. For final identification, pomegranate nsLTPs were purified by chromatography and subjected to trypsin digestion and mass spectrometry (MS) analysis. For this purpose, the sequences obtained by cDNA cloning of three pomegranate nsLTPs were integrated in the database that was subsequently searched for MS data interpretation. Four nsLTPs were identified by 2-D immunoblotting. The detected proteins showed different IgE-binding capacity and partial cross-reactivity with Pru p 3. cDNA cloning and MS analyses led to the identification of three nsLTP isoforms with 66-68% amino acid sequence identity named Pun g 1.0101, Pun g 1.0201 and Pun g 1.0301. By 2-D electrophoresis, we could separate different nsLTP isoforms possessing different IgE-binding properties, which might reflect peculiar allergenic potencies. The contribution of Pru p 3 to prime sensitization is not central as in other plant nsLTPs. © 2014 S. Karger AG, Basel.

    Nano-silver and its composite materials are widely used in medicine, food and other industries due to their strong conductivity, size effect and other special performances. So far, more microbial researches have been applied, but a plant method is rarely reported. In order to open up a new way to prepare AgNP composites, pomegranate peel extract was used in this work to reduce Ag+ to prepare Ag/Ag+/Ag3+ nanoparticle composites. UV-Vis was employed to detect and track the reduction of Ag+ and the forming process of AgNPs. The composition, structure and size of the crystal were analyzed by XRD and TEM. Results showed that, under mild conditions, pomegranate peel extract reacted with dilute AgNO3 solution to produce Ag/Ag+/Ag3+ nanoparticle composites. At pH = 8 and 10 mmol/L of AgNO3 concentration, the size of the achieved composites ranged between 15 and 35 nm with spherical shapes and good crystallinity. The bactericidal experiment indicated that the prepared Ag/Ag+/Ag3+ nanoparticles had strong antibacterial activity against gram positive bacteria and gram negative bacteria. FTIR analysis revealed that biological macromolecules with groups of sbnd NH2, sbnd OH, and others were distributed on the surface of the newly synthesized Ag/Ag+/Ag3+ nanoparticles. This provided a useful clue to further study the AgNP biosynthesis mechanism.

    Coadministered pomegranate rind extract (PRE) and zinc (II) produces a potent virucidal activity against Herpes simplex virus (HSV); however, HSV infections are also associated with localised inflammation and pain. Here, the objective was to determine the anti-inflammatory activity and relative depth penetration of PRE, total pomegranate tannins (TPT) and zinc (II) in skin, ex vivo. PRE, TPT and ZnSO 4 were dosed onto freshly excised ex vivo porcine skin mounted in Franz diffusion cells and analysed for COX-2, as a marker for modulation of the arachidonic acid inflammation pathway, by Western blotting and immunohistochemistry. Tape stripping was carried out to construct relative depth profiles. Topical application of PRE to ex vivo skin downregulated expression of COX-2, which was significant after just 6h, and maintained for up to 24h. This was achieved with intact stratum corneum, proving that punicalagin penetrated skin, further supported by the depth profiling data. When PRE and ZnSO 4 were applied together, statistically equal downregulation of COX-2 was observed when compared to the application of PRE alone; no effect followed the application of ZnSO 4 alone. TPT downregulated COX-2 less than PRE, indicating that tannins alone may not be entirely responsible for the anti-inflammatory activity of PRE. Punicalagin was found throughout the skin, in particular the lower regions, indicating appendageal delivery as a significant route to the viable epidermis. Topical application of TPT and PRE had significant anti-inflammatory effects in ex vivo skin, confirming that PRE penetrates the skin and modulates COX-2 regulation in the viable epidermis. Pomegranates have potential as a novel approach in ameliorating the inflammation and pain associated with a range of skin conditions, including cold sores and herpetic stromal keratitis.

    2004-01-01

    The effect of two extraction methods of pomegranate juice on its quality and stability was evaluated. The first method consisted of separation of the seeds from fruits and centrifugation. The second method consisted of squeezing fruit halves with an electric lemon squeezer. During a period of 72 hours of cold storage at 4°C, the juices were evaluated for the presence of sugars, organic acids, and anthocyanins. Delphinidin 3-glucoside was identified to be the major anthocyanin present at the level of 45–69 mg/L. Among the organic acids, oxalic and tartaric acids dominated. The major sugars detected in pomegranate juice were glucose and sucrose. No significant differences in the content of sugars, organic acids, or anthocyanins in juices obtained through application of the two different extraction methods were detected, with the exception of the drastic decrease of cyanidin 3,5-diglucoside level in juice obtained by seed centrifugation. The pH did not show differences between treatments. Titrable acidity and the level of sugars expressed as °Brix decreased after 32 and 15 hours after extraction, respectively, when juice was obtained by centrifuging the seeds. PMID:15577198

    Tannin-rich fruits have been evaluated as alternative prevention strategies for colorectal cancer based on their anti-inflammatory properties. This study compared tannin-rich preparations from mango (rich in gallotannins) and pomegranate (rich in ellagitannins) in the dextran sodium sulfate-induced colitis model. In rats, mango and pomegranate beverages decreased intestinal inflammation and the levels of pro-inflammatory cytokines in mucosa and serum. The mango beverage suppressed the ratio of phosphorylated/total protein expression of the IGF-1R-AKT/mTOR axis and downregulated mRNA expression of Igf1, Insr, and pik3cv. Pomegranate decreased p70S6K and RPS6, as well as Rps6ka2, Map2k2, and Mapk1 mRNA. In silico modeling indicated a high binding of docked of gallic acid to the catalytic domain of IGF-1R, which may suppress the activity of the enzyme. Ellagic acid docked effectively into the catalytic domains of both IGF-1R and EGFR. In vitro assays with lipopolysaccharide-treated CCD-18Co cells using polyphenolic extracts from each beverage, as well as pure compounds, corroborated the predictions made in silico. Mango polyphenols inhibited the IGF-1R- AKT/mTOR axis, and pomegranate polyphenols downregulate the mTOR downstream pathway through reductions in ERK1/2. These results suggest that extracts rich in gallo- and ellagitannins act on different molecular targets in the protection against ulcerative colitis. © 2016 WILEY-VCH Verlag GmbH & Co.

    1. Four experimental diets containing 0, 0.5, 1.0 and 2.0% fermented pomegranate by-products (FPB) were supplied to 320d-old broilers to evaluate the effects of FPB on growth performance, nutritional composition, fatty acid profile and oxidative stability of meat. 2. Dietary supplementation of FPB linearly increased the weight gain and feed intake of broilers with linear reduction in feed conversion ratio. 3. The crude protein, iron, magnesium, and sodium content were linearly higher, whereas cholesterol was linearly lower in the breast meat of FPB-supplemented broilers. In thigh meat, linearly lower ether extract and cholesterol with higher moisture was noted in response to increasing levels of FPB. 4. The proportion of saturated fatty acids was both linearly and quadratically lower in breast and thigh meat, whereas those of monounsaturated fatty acids of breast (linear and quadratic) and n-3 fatty acids of breast and thigh (linear) meat was higher in the FPB-supplemented broilers. The n-6/n-3 ratio of breast meat was linearly lower in response to FPB supplementation. The hypocholesterolaemic to hypercholesterolaemic ratio of thigh meat was higher in the FPB-supplemented groups. 5. The thiobarbituric acid reactive substances and pH value were lower in the breast and thigh meat of FPB-supplemented broilers. 6. Thus, additive supplementation of the diet with up to 2% FPB improved the nutritional quality, fatty acid profile and shelf life of broiler meat.

    Color is an important determinant of pomegranate fruit quality and commercial value. To understand the genetic factors controlling color in pomegranate, chemical, molecular and genetic characterization of a "white" pomegranate was performed. This unique accession is lacking the typical pomegranate color rendered by anthocyanins in all tissues of the plant, including flowers, fruit (skin and arils) and leaves. Steady-state gene-expression analysis indicated that none of the analyzed "white" pomegranate tissues are able to synthesize mRNA corresponding to the PgLDOX gene (leucoanthocyanidin dioxygenase, also called ANS, anthocyanidin synthase), which is one of the central structural genes in the anthocyanin-biosynthesis pathway. HPLC analysis revealed that none of the "white" pomegranate tissues accumulate anthocyanins, whereas other flavonoids, corresponding to biochemical reactions upstream of LDOX, were present. Molecular analysis of the "white" pomegranate revealed the presence of an insertion and an SNP within the coding region of PgLDOX. It was found that the SNP does not change amino acid sequence and is not fully linked with the "white" phenotype in all pomegranate accessions from the collection. On the other hand, genotyping of pomegranate accessions from the collection and segregating populations for the "white" phenotype demonstrated its complete linkage with the insertion, inherited as a recessive single-gene trait. Taken together, the results indicate that the insertion in PgLDOX is responsible for the "white" anthocyanin-less phenotype. These data provide the first direct molecular, genetic and chemical evidence for the effect of a natural modification in the LDOX gene on color accumulation in a fruit-bearing woody perennial deciduous tree. This modification can be further utilized to elucidate the physiological role of anthocyanins in protecting the tree organs from harmful environmental conditions, such as temperature and UV radiation.

    Single-cell RNA sequencing (scRNA-Seq) is an increasingly popular platform to study heterogeneity at the single-cell level. Computational methods to process scRNA-Seq data are not very accessible to bench scientists as they require a significant amount of bioinformatic skills. We have developed Granatum, a web-based scRNA-Seq analysis pipeline to make analysis more broadly accessible to researchers. Without a single line of programming code, users can click through the pipeline, setting parameters and visualizing results via the interactive graphical interface. Granatum conveniently walks users through various steps of scRNA-Seq analysis. It has a comprehensive list of modules, including plate merging and batch-effect removal, outlier-sample removal, gene-expression normalization, imputation, gene filtering, cell clustering, differential gene expression analysis, pathway/ontology enrichment analysis, protein network interaction visualization, and pseudo-time cell series construction. Granatum enables broad adoption of scRNA-Seq technology by empowering bench scientists with an easy-to-use graphical interface for scRNA-Seq data analysis. The package is freely available for research use at http://garmiregroup.org/granatum/app.

    Xylocarpus granatum Koenig, widely used in folk medicine in southeast countries, has been reported to exert neuropharmacological activities as well as mood regulation. The neuroprotective activities of limonoids, riches in X. granatum, are poorly understood. To investigate the potential antidepressant-like effects and the underlying mechanisms of cipadesin A, one limonoid component, extracted from X. granatum, in acute stress-induced depression mouse models. Antidepressant-like effects of cipadesin A were investigated through behavioral tests, and potential mechanism was assessed by neuroendocrine system. Antidepressant-like effects of cipadesin A (5, 15, 50mg/kg/day for 7days, intragastrically) were estimated through forced-swimming test (FST), tail suspension test (TST) and open field test (OFT). Effects of cipadesin A on hypothalamus-pituitary- adrenal (HPA) axis were evaluated by analysis of serum corticosterone (CORT) and adrenocorticotropic hormone (ACTH) using enzyme-linked immunosorbent assay (ELISA). Cipadesin A administration significantly reduced the floating time in the FST and immobility time in the TST (15-50mg/kg). Cipadesin A dose-dependently increased the time in the central zone in the OFT (5-50mg/kg), without altering the locomotor activity. Moreover, repeated cipadesin A treatment significantly inhibited the increase levels of serum CORT (5-50mg/kg), ACTH (15-50mg/kg) following the forced swimming, but not in the absence of stress. Cipadesin A has antidepressant-like activities in acute stressed mice model of depression, which likely occurs by inhibiting the HPA axis activity response to stress. These data support further exploration for developing cipadesin A as a potential agent to treat depression and anxiety disorders. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    The analysis of pomegranate phenolic compounds belonging to different classes in different fruit parts was performed by high-performance liquid chromatography coupled with photodiode array and mass spectrometry detection. Two different separation methods were optimized for the analysis of anthocyanins and hydrolyzable tannins along with phenolic acids and flavonoids. Two C 18 columns, core-shell and fully porous particle stationary phases, were used. The parameters for separation of phenolic compounds were optimized considering chromatographic resolution and analysis time. Thirty-five phenolic compounds were found, and 28 of them were tentatively identified as belonging to four different phenolic compound classes; namely, anthocyanins, phenolic acids, hydrolyzable tannins, and flavonoids. Quantitative analysis was performed with a mixture of nine phenolic compounds belonging to phenolic compound classes representative of pomegranate. The method was then fully validated in terms of retention time precision, expressed as the relative standard deviation, limit of detection, limit of quantification, and linearity range. Phenolic compounds were analyzed directly in pomegranate juice, and after solvent extraction with a mixture of water and methanol with a small percentage of acid in peel and pulp samples. The accuracy of the extraction method was also assessed, and satisfactory values were obtained. Finally, the method was used to study identified analytes in pomegranate juice, peel, and pulp of six different Italian varieties and one international variety. Differences in phenolic compound profiles among the different pomegranate parts were observed. Pomegranate peel samples showed a high concentration of phenolic compounds, ellagitannins being the most abundant ones, with respect to pulp and juice samples for each variety. With the same samples, total phenols and antioxidant activity were evaluated through colorimetric assays, and the results were correlated among them.

    Pomegranates fruit extracts have several activities, among others, anti-inflammatory, antibacterial, and antioxidants that have the main content punicalagin and ellagic acid. Pomegranate has the ability of various therapies through different mechanisms. Vascular endothelial growth factor (VEGF) function was to form new blood vessels produced by various cells one of them was macrophages. Platelet-derived growth factor (PDGF) was a growth factor proven chemotactic, increased fibroblast proliferation and collagen matrix production. In addition, VEGF and PDGF synergize in their ability to vascularize tissues. The PDGF function was to stabilize and regulate maturation of new blood vessels. Activities of pomegranate fruit extract were observed by measuring the increased of VEGF and PDGF expression as a marker of wound healing process. To investigate the potential of pomegranate extracts on the tooth extraction wound to increase the expression of VEGF and PDGF on the 4 th day of wound healing process. This study used 12 Cavia cobaya , which were divided into two groups, namely, the provision of 3% sodium carboxymethyl cellulose and pomegranate extract. The 12 C. cobaya would be executed on the 4 th day, the lower jaw of experimental animals was taken, decalcified about 30 days. The expression of VEGF and PDGF was examined using immunohistochemical techniques. The differences of VEGF and PDGF expression were evaluated statistically using t-test. Statistically analysis showed that there were significant differences between control and treatment groups (p<0.05). Pomegranate fruit extract administration increased VEGF and PDGF expression on post-tooth extraction wound.

    The aim of this study was to evaluate genetic divergence in the 'Carioca' (beige with brown stripes) common bean cultivar used by different institutions and in 16 other common bean cultivars used in the Rede Cooperativa de Pesquisa de Feijão (Cooperative Network of Common Bean Research), by using simple sequence repeats associated with agronomic traits that are highly distributed in the common bean genome. We evaluated 22 polymorphic loci using bulks containing DNA from 30 plants. There was genetic divergence among the Carioca cultivar provided by the institutions. Nevertheless, there was lower divergence among them than among the other cultivars. The cultivar used by Instituto Agronômico do Paraná was the most divergent in relation to the Carioca samples. The least divergence was observed among the samples used by Universidade Federal de Lavras and by Embrapa Arroz e Feijão. Of all the cultivars, 'CNFP 10104' and 'BRSMG Realce' showed the greatest dissimilarity. The cultivars were separated in two groups of greatest similarity using the Structure software. Genetic variation among cultivars was greater than the variation within or between the groups formed. This fact, together with the high estimate of heterozygosity observed and the genetic divergence of the samples of the Carioca cultivar in relation to the original provided by Instituto Agronômico de Campinas, indicates a mixture of cultivars. The high divergence among cultivars provides potential for the utilization of this genetic variability in plant breeding.

    Cytomorphological characterization was performed on tea cultivars, three each of Camellia sinensis and Camellia assamica species. For plant morphological study, one and a half year old healthy shoots were obtained from the selected mother bushes of the six tea cultivars. The field experiment conducted in randomized complete block design having four replications was aimed at evaluating plant height, number of leaves plant-l, number of branches plant-l, number of flowers plant-1, fresh and dry leaf weight plant-I. The data indicated significant difference between the two species with narrow leaved cultivars having increased plant height, number of leaves and branches plant-I than the broad leaved cultivars, but less number of flowers plant-l, fresh and dry leaf weight. Karyotype analysis indicated that both the groups are diploid with 2n = 30. On the basis of chromosome morphology, C. assamica had larger chromosomes (3-10.5 mu m) as compared to C. sinensis (3.9-8 mu m). C. assamica has relatively advanced features as compared to C. sinensis. However, both the groups possessed mostly median to sub-median centromeres with no secondary constrictions which possibly indicates that little or no evolutionary changes have taken place in tea and that the karyotype is still at a primitive stage, with C. sinensis being more primitive than C. assamica. Our results suggest that both the groups are different from each other in morphological as well as cytological attributes and could therefore generate more germplasm if the two species could be involved in tea breeding programs.

  10. Molecular characterisation of radish cultivars

    Directory of Open Access Journals (Sweden)

    Sara Michelly Cruz

    Full Text Available The radish has been gaining importance in the Brazilian market due to its use as a green manure and cover crop, and also due to its potential for the production of biodiesel, however there are only two registered cultivars, which are morphologically very similar. Determination of genetic purity is a prerequisite in marketing seeds as it ensures uniformity of the crop and is important in breeding programs. The aim of this work therefore was to evaluate the similarity and genotype patterns which permit differentiation of the commercial radish cultivars IPR 116 and CATI AL-1000. In order to do this, isoenzyme electrophoretic patterns were analysed in dry seeds, soaked seeds, seedling leaves and young leaves; the isoenzymes used being: superoxide dismutase, catalase, esterase, glutamate-oxalocetate, malate dehydrogenase and isocitrate lyase. Thirty-seven RAPD primers and 10 ISSR primers in leaves of the CATI AL-1000 and IPR-116 cultivars were analysed. Among the isoenzymes under study, the most polymorphic were glutamate oxalocetate, malate dehydrogenase, esterase and superoxide dismutase, with the superoxide dismutase system giving the best characterisation for all stages of development. The catalase isoenzyme system did not make it possible to differentiate between cultivars at any stage of development, and isocitrate lyase was not revealed by the protocol used. In analysis of the markers, 27 RAPD primers and eight ISSR primers showed polymorphism. The results indicate that it is possible to determine reliable descriptors based on isoenzymes at different stages of development of the radish and with the use of RAPD and ISSR primers.

    Full Text Available This study was conducted to determine the best pollinizer for five selected pecan cultivars in southwest of Iran at Safiabad Agricultural Research Center in 2014-2015. The cultivars included: 'GraTex', '10J', 'Wichita 6J', 'GraKing', 'Choctaw' as pollinated cultivars (♀ and 'GraTex', 'Peruque', 'Comanche 4M', '10J', 'Wichita 6J', 'Mohawk', 'Mahan', 'Stuart 2J', '3J', 'Stuart 4J', 'GraKing', 'Choctaw', 'Apache', '6M', 'Wichita 7J' and 'Comanche 5M.' as pollinizer cultivars (♂. In the first step, a pollination chart of cultivars was determined in two years. The pollination chart of cultivars showed that all the cultivars investigated during this study were dichogamous and also protogynous except for the 'Peruque'. ‘GraKing’ had the longest duration of shedding pollen. Pollination chart showed that 'Peruque', ‘GraKing’, and 'Stuart 2J' had flowering overlap with the selected cultivars. Pollen germination test showed that the germination ability was different among the cultivars. It was 45% for 'GraKing' and 35% for 'Peruque', which were both recommended as pollinizers in this study. '6M', 'GraTex' and 'Stuart 4J' cultivars had the highest pollen germination percentage of 65%, 60% and 60%, respectively. The results of controlled pollinationtest showed that different pollen sources had no significant effect on nuts per cluster but self-pollinated all of the cultivars significantly reduced fruit set in first and second years. Based on the present research, pollination in pecan orchard was necessary for adequate yield. Also, 'Peruque', 'GraKing' and 'Stuart 2J' were the best pollinizers for five selected cultivars in southwest of Iran.

  13. Cannabis - from cultivar to chemovar.

    2012-01-01

    The medicinal use of Cannabis is increasing as countries worldwide are setting up official programs to provide patients with access to safe sources of medicinal-grade Cannabis. An important question that remains to be answered is which of the many varieties of Cannabis should be made available for medicinal use. Drug varieties of Cannabis are commonly distinguished through the use of popular names, with a major distinction being made between Indica and Sativa types. Although more than 700 different cultivars have already been described, it is unclear whether such classification reflects any relevant differences in chemical composition. Some attempts have been made to classify Cannabis varieties based on chemical composition, but they have mainly been useful for forensic applications, distinguishing drug varieties, with high THC content, from the non-drug hemp varieties. The biologically active terpenoids have not been included in these approaches. For a clearer understanding of the medicinal properties of the Cannabis plant, a better classification system, based on a range of potentially active constituents, is needed. The cannabinoids and terpenoids, present in high concentrations in Cannabis flowers, are the main candidates. In this study, we compared cultivars obtained from multiple sources. Based on the analysis of 28 major compounds present in these samples, followed by principal component analysis (PCA) of the quantitative data, we were able to identify the Cannabis constituents that defined the samples into distinct chemovar groups. The study indicates the usefulness of a PCA approach for chemotaxonomic classification of Cannabis varieties. Copyright © 2012 John Wiley & Sons, Ltd.

    Full Text Available ABSTRACT Zinc (Zn is an essential micronutrient for plants, due to its role as a functional, structural, or regulatory cofactor in a large number of enzymes. The element is necessary for the synthesis of tryptophan, which is a precursor of indoleacetic acid. The aim of this study was to evaluate the behavior of two cowpea cultivars fertilized with four doses of Zn (0.0, 2.0, 4.0, and 6.0 kg of Zn ha-1 regarding dry grain yield (PGS, in addition to quantifying leaf and grain Zn content and grain crude protein. The experiment was conducted in the town of Brejo, in the state of Maranhão, Brazil. A 4 x 2 factorial scheme was used with four replications. Response functions were adjusted by calculating the Zn doses which provided a maximum technical efficiency for each genotype. The tested cultivars of cowpea showed no great difference regarding Zn demand applied to the soil, ranging from 3.2 to 3.4 kg of Zn ha-1 for BRS Tumucumaque and BRS Guariba, respectively. Concerning Zn use efficiency, BRS Guariba was more responsive than was BRS Tumucumaque, i.e. the same dose of Zn produced 70 kg grain and 2.1 kg crude protein per hectare.

    2015-01-01

    Full Text Available The conservation and sustainable use of grapevine biodiversity in Armenia is particularly important due to the large number of traditional local varieties. Being partially different from European grapevine gene pool, the material of Armenian local cultivars significantly contributes to the understanding of the genetic variation and is valuable source for target selection. During last years many Armenian grapevine cultivars have been already described and their genotypes determined, but some local varieties and wild accessions remain unidentified and their phenotypic characteristics overlooked. The comprehensive analysis of phenotypes is essential for research, including genetic association studies, cultivar evaluation and selection. The goal of our research was the phenotyping on the base of reproductive, carpological and analytical characteristics of 80 Armenian aboriginal and new grape cultivars. Description of phenotypic profiles is important step towards identification and conservation of genetic resources of Armenian grapes. In future, these data can be applied for breeding of improved grape varieties targeted to fresh consumption and wine production.

    Full text: Mutation breeding of jujube (Ziziphus mauritiana Lin.) received attention by the Food Crops Research Institute since 1978. Mutations can be directly released as new cultivars or indirectly as bud grafting source. N-methyl-N-nitroso urea (MNH) was used at a concentration of 0.02-0.04% for 12 h treatment of pre-germinated seeds of different jujube cultivars. Some useful mutants were selected and directly released as new cultivars to farmers. Of the selected mutants two cultivars, ''Ma hong'' and ''Dao tien'', are the most preferable and popularly grown in the country. ''Ma hong'' is a mutant of ''Gia Loc'', a very popular cultivar. Main useful traits of ''Gia Loc'' such as early maturing, two crops of fruits per year are maintained (harvest in December and August). ''Ma hong'' has round-formed, pink rose coloured, sweeter fruits and stable fruit yield in off-season (Aug.) as compared with oval-formed, yellow-coloured and sour fruit of ''Gia Loc''. ''Dao tien'' is a mutant of the local variety ''Thien Phien'' with quite different traits. The original cultivar is late maturing (harvested in Feb.) with one crop of fruit per year and has small fruits (mean wt. of fruit at harvest 20 g). ''Dao tien'' is one month earlier in maturing allowing two crops of fruit per year (harvested in Jan. and Nov.). Fruits are round-formed, bigger (mean wt. of fruit: 25 g) and more tasteful (peach-flavored and brittle). (author)

    Lin, Y S; Kuan, C S; Weng, I S; Tsai, C C

    2015-11-25

    The genetic relationships among 27 pineapple [Ananas comosus (L.) Merr.] cultivars and lines were examined using 16 simple sequence repeat (SSR) markers. The number of alleles per locus of the SSR markers ranged from 2 to 6 (average 3.19), for a total of 51 alleles. Similarity coefficients were calculated on the basis of 51 amplified bands. A dendrogram was created according to the 16 SSR markers by the unweighted pair-group method. The banding patterns obtained from the SSR primers allowed most of the cultivars and lines to be distinguished, with the exception of vegetative clones. According to the dendrogram, the 27 pineapple cultivars and lines were clustered into three main clusters and four individual clusters. As expected, the dendrogram showed that derived cultivars and lines are closely related to their parental cultivars; the genetic relationships between pineapple cultivars agree with the genealogy of their breeding history. In addition, the analysis showed that there is no obvious correlation between SSR markers and morphological characters. In conclusion, SSR analysis is an efficient method for pineapple cultivar identification and can offer valuable informative characters to identify pineapple cultivars in Taiwan.

Treatment EC 5 did not affect the seedling emergence, regardless of cultivar. Compared to the control, EC 10 reduced the seedling emergence of switchgrass ‘Alamo’, ‘Cimarron’, and ‘NL 94C2-3’ by 44%, 33%, and 82%, respectively. All switchgrass cultivars under EC 10 had a 46% to 88% reduction in the seedling emergence index except ‘NSL 2009-2’. No switchgrass seedlings emerged under EC 20. In summary, high salinity negatively affected switchgrass seedling emergence and growth. Dendrogram and cluster of six switchgrass cultivars indicated that ‘Alamo’ was the most tolerant cultivar, while ‘NSL 2009-2’ was the least tolerant cultivar at both seedling emergence and growth stages. A growth-stage dependent response to salinity was observed for the remaining switchgrass cultivars. ‘NSL 2009-1’ and ‘NL 94C2-3’ were more tolerant to salinity than ‘Cimarron’ and ‘Kanlow’ at the seedling emergence stage; however, ‘Kanlow’ and ‘Cimarron’ were more tolerant to salinity than ‘NSL 2009-1’ and ‘NL 94C2-3’ at the seedling growth

The genetic diversity of rye cultivars by 6 SSR markers was evaluated. Six specific microsatellite primer pairs produced 58 polymorphic alleles with an average of 9.7 alleles per locus. The number of alleles ranged from 6 (SCM2 to 14 (SCM86. Genetic polymorphism was characterized based on diversity index (DI, probability of identity (PI and polymorphic information content (PIC. The diversity index (DI of SSR markers ranged from 0.5478 (SCM2 to 0.887 (SCM86 with an average of 0.778. The lowest value of polymorphic information content was recorded for SCM2 (0.484 and the highest value for SCM86 (0.885 of PIC was detected in SCM86 with an average of 0.760.The dendrogram of genetic similarity was constructed, based on UPGMA algorithm. The hierarchical cluster analysis divided rye genotypes into 4 main clusters. The first cluster of 14 genotypes was subdivided in two subclusters (1a and 1b where 50% of genotypes were Czechoslovak origin. The second cluster contained four genotypes were three (75% of them had Czech or Czechoslovak origin. In the third subcluster separated three rye genotypes of different origin. The rest (24 of rye genotypes in the fourth cluster were divided into two subclusters (4a and 4b where clearly separated group of Polish (4aa and Czech and Czechoslovak (4ab genotypes. Two genotypes of 4aa subcluster (Wojcieszyckie and Dankowskie Nowe from Poland were genetically the closest. In the dendrogram alle genotypes were differentiated and clustering partially reflects geographic origin of studied rye genotypes. In this experiment, SSRs markers proved to be a high informative and usefull tool in genetic diversity research for the distinguishing and characterization of close related varieties.

    2014-04-29

    Manual cultivar identification diagram is a new strategy for plant cultivar identification based on DNA markers, providing information to efficiently separate cultivars. We tested 25 pairs of apple EST-SSR primers for amplification of PCR products from loquat cultivars. These EST-SSR primers provided clear amplification products from the loquat cultivars, with a relatively high transferability rate of 84% to loquat; 11 pairs of primers amplified polymorphic products. After analysis of 24 red-fleshed loquat accessions, we found that only 7 pairs of primers could clearly separate all of them. A cultivar identification diagram of the 24 cultivars was constructed using polymorphic bands from the DNA fingerprints and EST-SSR primers. Any two of the 24 cultivars could be rapidly separated from each other, according to the polymorphic bands from the cultivars; the corresponding primers were marked in the correct position on the cultivar identification diagram. This red-flesh loquat cultivar identification diagram can separate the 24 red-flesh loquat cultivars, which is of benefit for loquat cultivar identification for germplasm management and breeding programs.

    In the current research the effect of probiotic microorganisms viz; Lactococcus lactis and Lactobacillus plantarum on fermentation of Camellia sinensis and Punica grantum was studied. In vitro test were done to analyze the anticancer, antioxidant and atherosclerosis (clot lysis) properties of fermented juice. The juice was fermented for 48 and 96h, during which concentration of phenolic content, total acid content and free radical scavenging activity of the sample was analyzed by DPPH assay (α, α-diphenyl-β-picrylhydrazyl). Dropping of pH was observed after 48 h of fermentation. The clot lysis activity was found to be 80 % in 100μl concentration of fermented cocktail juice. The 96 h fermented sample has shown around 70% inhibition against colon cancer cell lines. Analytical study of HPLC proves the organic acid production such as ascorbic acid in superior amount for 96h of fermented sample, Based on the retention time, the corresponding peaks were detected at 4.919 and 4.831 min.

    2013-01-01

    Peach (Prunus persica (L.) Batsch) is one of the most popular stone fruits, commercially produced largely in Mediterranean and, to a lesser extent, in continental climatic conditions. Several breeding programs with different aims release annually large numbers of new cultivars. Micropropagation offers a suitable method to provide the growers of sufficient quantities of rootstocks, as well as of pathogen-free planting material of old and new cultivars.An effective four-step micropropagation procedure for cultivar and rootstock production is described here, based on the use of modified MS and WPM media. The health status of the initial shoot tips is very important, also because the growth and proliferation rate of shoot cultures from virus-infected clones are generally very poor. Proliferation and elongation phases depend on the major macro-elements, as well as the content and ratio of plant growth regulators. It is important to grow the cultures at 22°C, as hyperhydricity may develop at higher temperatures. Although sucrose is the most common carbon source used during proliferation and rooting, for some peach cultivars and rootstocks the replacement of sucrose (10 g/L) with glucose (20 g/L) in the rooting medium improves the rooting and survival rates of plants in the acclimatization phase. The rooting rate of the rootstock "Cadaman" is improved with the chelated form of iron FeEDDHA at 150 mg/L. Rooted plants are acclimatized in greenhouse under high humidity conditions.

    Variations in cadmium accumulation and translocation among 40 Chinese cabbage cultivars were studied to identify and screen out Cd-safe cultivars (CSCs), i.e. cultivars with low enough accumulation of Cd in their edible parts even when grown in contaminated soils. It was observed in the pot-culture experiment that there was a significant difference (p < 0.05) in shoot Cd concentrations under three Cd treatments (1.0, 2.5 and 5.0 mg/kg), with corresponding average values 0.88, 4.45 and 7.76 mg/kg, respectively. Shoot Cd concentrations in 16 cabbage cultivars were lower than 0.50 mg/kg. The translocation factors (TFs) and the extraction factors (EFs) in five cabbage cultivars were lower than 1.0 in the pot-culture experiment. The field-culture experiment further validated that New Beijing 3 and Fengyuanxin 3 could be considered as CSCs. In particular, the two cultivars can be cultivated in low to moderate Cd-contaminated soils (Cd concentration <1.25 mg/kg) to minimize the Cd accumulation in the food.

    2018-04-16

    Potato cultivars vary in their tolerance to common scab (CS), however how they affect CS-causing Streptomyces spp. populations over time is poorly understood. This study investigated the effects of potato cultivar on pathogenic Streptomyces spp. abundance, measured using quantitative PCR, in three spatial locations in a CS-infested field: 1) soil close to the plant (SCP); 2) rhizosphere (RS); and 3) geocaulosphere (GS) soils. Two tolerant (Gold Rush, Hindenburg) and two susceptible cultivars (Green Mountain, Agria) were tested. The abundance of pathogenic Streptomyces spp. significantly increased in late August compared with other dates in RS of susceptible cultivars in both years. Abundance of pathogenic Streptomyces spp., when averaged over locations and time, was significantly greater in susceptible cultivars compared with tolerant cultivars in 2014. Principal coordinates analysis showed that SCP and RS soil properties (pH, organic carbon and nitrogen concentrations) explained 68% and 76% of total variation in Streptomyces spp. abundance among cultivars in 2013, respectively, suggesting that cultivars influenced CS pathogen growth conditions. The results suggested that the genetic background of potato cultivars influenced the abundance of pathogenic Streptomyces spp., with 5 to 6 times more abundant Streptomyces spp. in RS of susceptible cultivars compared with tolerant cultivars, which would result in substantially more inoculum left in the field after harvest.  .

    2008-07-01

    Six rose mutants evolved at the Indian Agricultural Research Institute, New Delhi from four parent cultivars were characterized based on RAPD markers. Contrary to the earlier findings our effort has conclusively proven that the RAPD markers are indeed robust tools to discern the mutants from their parents. Among 40 primers screened, 7 primers produced inconsistent banding pattern. The number of polymorphic bands varied between 4 (OPA 14) and 10 (OPA1) with an average of 6.5 bands per primer. The percentage polymorphism ranged from 62.5 (OPM 9) to 100 percent (OPA 1). Most of the primers produced monomorphic bands between parent and mutant rose cultivars. When primer OPA 2 was used a specific band of 2.5 kb was noticed in mutant cv. Pusa Urmil and cv. Pusa Abhishek but was absent in parent cv. Jantar Mantar. A polymorphic band of 750 bp was noticed in the parent Kiss of Fire and helped in differentiating the parent from its mutant when amplified with OPK 3. Primer OPS 16 produced discriminatory band of 800 bp in mutant cv. Pink Sport of Montezuma while it was absent in its parent cv. Montezuma. Another specific band of 650 bp was present in parent cv. Montezuma and absent in its mutant cv. Pink Sport of Montezuma signifying the uniqueness of the mutant. Primer OPM 5 brought out distinct polymorphism among the parent Jantar Mantar and its three mutants with absence of a specific band of 1.5 kb in the parent. The four parents and 6 mutants were divided into four distinct groups in the Dendogram constructed by UPGMA method. The most genetically similar cultivar among the 10 cultivars analyzed are Montezuma and its pink sport of Montezuma whereas Abhisarika a mutant of cv. Kiss of Fire was distinctly different and formed a separate cluster. (author)

  19. Relative competitiveness of soybean cultivars with barnyardgrass

    Directory of Open Access Journals (Sweden)

    Marlon Ouriques Bastiani

    Full Text Available ABSTRACT The aim of this work was to evaluate the competitiveness between soybean cultivars and barnyardgrass, based on morphological and physiological characteristics of species. The experiments were conducted in completely randomized experimental design, with 4 replications. In the first study, for both soybean and barnyardgrass, it was determined the population of plants in which shoot dry matter became constant and independent of the population (16 plants∙pot−1 or 400 plants∙m−2. In the second study, 2 experiments were conducted to evaluate the competitiveness of BMX Apolo RR and BMX Potência RR soybean cultivars with barnyardgrass plants, both carried out in replacement series under different proportions of plants∙pot−1 (100:0; 75:25; 50:50; 25:75 and 0:100 between the crop and the weed. The analysis of the species competitiveness was determined through diagrams applied to replacement series experiments and use of relative competitiveness indexes. At 44 days after the emergence of species, the physiological and morphological parameters of the crop and the weed were evaluated. The BMX Apolo RR and BMX Potência RR soybean cultivars show similar competitiveness when competing with the barnyardgrass; therefore, the ability of one species to interfere on another is equivalent. For plant height, barnyardgrass displays higher competitiveness compared to BMX Apolo RR, with early cycle and short height. The intraspecific competition is more important to barnyardgrass than interspecific competition with soybean cultivars, resulting in negative effects on the morphological and physiological characteristics of species.

    Full Text Available The severe winter which occurred in Poland in 1986-1987 damaged the most part of scab resistant apple cultivars and selected apple hybrids. Cold hardiness studied in 1987 and 1988 showed significant differences in degree of frost injury on stem, branches, twigs and buds of apple trees. Two scab-resistance cultivars, namely Florina and Sir Prize, as well as two check culuvars, Idared and Golden Delicious, were killed by frost. Strong damages were noted in cultivars: Prima, Primula, and Priam. Lower susceptibility showed: Jonafree, Gavin, Liberty Sister and three hybrids selected from crosses of Bankroft with scab-resistant Primula. Relatively frost resistant was Novamac and three hybrids of U-breeding line: U-1101 and U-50, originated from crosses of polish culrivar Fantazja (McIntosh x Linda with Primula, Highest resistance to frost showed cultivars: Freedom. Liberty. new polish cultivar Witos (Fantazja x Primula and three hybrids: U-337, U-237 and U-1098. During the 1987 and 1988 seasons severe infection of apple trees by numerous fungi was noted. Twelve species of isolated fungi were identified as pathogens of apple trees bark and wood.

  1. Epistatic association mapping in homozygous crop cultivars.

    Directory of Open Access Journals (Sweden)

    Hai-Yan Lü

    Full Text Available The genetic dissection of complex traits plays a crucial role in crop breeding. However, genetic analysis and crop breeding have heretofore been performed separately. In this study, we designed a new approach that integrates epistatic association analysis in crop cultivars with breeding by design. First, we proposed an epistatic association mapping (EAM approach in homozygous crop cultivars. The phenotypic values of complex traits, along with molecular marker information, were used to perform EAM. In our EAM, all the main-effect quantitative trait loci (QTLs, environmental effects, QTL-by-environment interactions and QTL-by-QTL interactions were included in a full model and estimated by empirical Bayes approach. A series of Monte Carlo simulations was performed to confirm the reliability of the new method. Next, the information from all detected QTLs was used to mine novel alleles for each locus and to design elite cross combination. Finally, the new approach was adopted to dissect the genetic basis of seed length in 215 soybean cultivars obtained, by stratified random sampling, from 6 geographic ecotypes in China. As a result, 19 main-effect QTLs and 3 epistatic QTLs were identified, more than 10 novel alleles were mined and 3 elite parental combinations, such as Daqingdou and Zhengzhou790034, were predicted.

    Full Text Available One of the most important criteria in breeding process of perennial grasses is maturity. Cultivars with different maturity play a very important role in utilization of perennial grasses, by providing the ability to create a mixture of different aspects utilization and time. The first grass species in Serbia whose breeding program involved this criterion was cocksfoot (Dactylis glomerata L.. In general cocksfoot is early to medium-early in maturity in comparison with other grasses and legumes, and that is mayor problem since in the optimum phase for cutting, cocksfoot is often earlier then other species in mixtures. As a result of this work, in the previous period, two cultivars of different maturity were released, Kruševačka 24 (K-24 and Kruševačka 25 (K-25. K-24 is medium and K-25 is late in maturity. New material is adapted to local agro-ecological conditions and productive in the same time. In breeding process of both cultivars initial material originated from autochthonous populations collected in eastern and central Serbia. Material from the wild flora is selected based on medium and late maturity which is already adapted and has good productivity. We applied the standard method of phenotypic recurrent selection with the creation of synthetic varieties by polycross.

The bulbs of cultivar ‘74-x’ had the highest phenolic content (total phenolic, flavonoids) and the strongest antioxidant capacity (DPPH, FRAP, and CUPRAC), followed by bulbs of cultivar ‘Hanzhong purple’; the bulbs of cultivar ‘Gailiang’ had the lowest phenolic content and antioxidant capacity (FRAP, CUPRAC, MCA). The bolts of ‘Hanzhong purple’ also had higher phenolic content. Principal components analysis (PCA) separated the cultivars into 3 groups according to phenolic and flavonoid contents and strength of antioxidant activity. The first group had higher HRSC, FRAP, and flavonoid content; the second group had higher total phenolic content and MCA; some cultivars in the third group had higher HRSC and FRAP. All 8 test garlic bulb extracts successfully prevented Human Vascular Endothelial Cell death and significantly prevented reactive-oxygen species (ROS) formation in oxidative stress model, in which cultivar ‘74-x’ had highest protection capability, following by cultivar ‘Hanzhong purple’, and the bulbs of cultivar ‘No. 105 from Korea’ had the lower protection capability against cell death and ROS formation. The protection capability in vivo of these garlic cultivars was consistent with their phenolic content and antioxidant capacity. PMID:24232741

    Large areas of contaminated land are being used for agricultural production in some countries due to the high demand for food. To minimize the influx of pollutants to the human food chain through consumption of agricultural products, we propose the concept of pollution-safe cultivars (PSCs), i.e. cultivars whose edible parts accumulate a specific pollutant at a level low enough for safe consumption, even when grown in contaminated soil. We tested the feasibility of the PSC concept by growing 43 cultivars of paddy rice (Oryza sativa L., including 20 normal and 23 hybrid cultivars) under a high (75.69-77.55 mg kg(-1)) and a low (1.75-1.85 mg kg(-1)) cadmium (Cd) exposure. These pot experiments took place in the spring and summer of 2004. At the low level of Cd exposure, 30 out of the 43 tested cultivars were found to be Cd-PSCs. Grain Cd concentrations were highly correlated (price grain is genotype-dependent and that the selection of PSCs is possible, at least at a certain level of soil contamination. No Cd-PSCs were found under the high level of Cd exposure. Yield was enhanced in some cultivars and depressed in others in response to elevated soil Cd, indicating that farmers cannot rely on yield depression as an indicator of toxicity of the grains. It is therefore important and feasible to screen for PSCs and to establish PSC breeding programs to effectively and efficiently reduce the risk of human exposure to soil pollutants, such as Cd, through crop consumption.

    More than 80% of the world's almonds are grown in California with several dozen almond cultivars available commercially. To facilitate promotion and sale, almond cultivars are categorized into marketing groups based on kernel shape and appearance. Several marketing groups are recognized, with the Nonpareil Marketing Group (NMG) demanding the highest prices. Placement of cultivars into the NMG is historical and no objective standards exist for deciding whether newly developed cultivars belong in the NMG. Principal component analyses (PCA) were used to identify nut and kernel characteristics best separating the 4 NMG cultivars (Nonpareil, Jeffries, Kapareil, and Milow) from a representative of the California Marketing Group (cultivar Carmel) and the Mission Marketing Group (cultivar Padre). In addition, discriminant analyses were used to determine cultivar misclassification rates between and within the marketing groups. All 19 evaluated carpological characters differed significantly among the 6 cultivars and during 2 harvest seasons. A clear distinction of NMG cultivars from representatives of the California and Mission Marketing Groups was evident from a PCA involving the 6 cultivars. Further, NMG kernels were successfully discriminated from kernels representing the California and Mission Marketing Groups with overall kernel misclassification of only 2% using 16 of the 19 evaluated characters. Pellicle luminosity was the most discriminating character, regardless of the character set used in analyses. Results provide an objective classification of NMG almond kernels, clearly distinguishing them from kernels of cultivars representing the California and Mission Marketing Groups.

    Full Text Available The paper presents principal properties of 5 new cultivars of small grains created in the Center for Agricultural and Technological Research in Zaječar. They are as follows: Arena (winter bread wheat, Premium (winter malting barley, Tango (winter triticale, Center (spring oat and Balsa (spring naked barley. In 2004 and 2005 these cultivars were registered by the Ministry of Agriculture, Forestry and Water Management of the Republic of Serbia. The Arena cultivar has good indices of technological quality and high yield genetic potential which is successfully preserved even in dry years. The Premium cultivar, besides high yield capacity, has a very low protein grain content what makes it especially suitable for brewers industry. Triticale Tango is intended, in the first place, for animal feeds and like Arena cultivar. is highly tolerant to draught. Spring oat Center is Zaječar's first made oat cultivar in this group of small grains. Cultivar Balsa is the first spring six-row naked barley in Serbia and Montenegro. Creating of Balsa cultivar is the attempt to meet the future demands on the market. By the act of registering above mentioned cultivars the Center in Zajecar has completed and enlarged its already existing variety of small grains assortment.

    Full Text Available ABSTRACT: Evaluation of yield performance is important to find the most adapted blueberry cultivars in a particular region. This research aimed to evaluate the flowering and hasvesting periods, the production per plant, and fruit quality of eight rabbiteye blueberry cultivars (Aliceblue, Bluebelle, Bluegem, Briteblue, Climax, Delite, Powderblue, and Woodard and two highbush blueberries (Georgiagem and O’Neal, in mild winter conditions in Pinhais-PR. Flowering and harvesting periods, production, berry weight, size, pH, soluble solids, titratable acidity, ratio and color of the fruits were evaluated in the 2013/2014 and 2014/2015 growing seasons, when the plants had two and three years old, respectively. Cultivars flowered from August to September, and harvest was concentrated in November and December. Berry weight, size, pH, soluble solids and acidity varied among the cultivars. The average ratios of 14.97 and 13.39 for each crop proved that the cultivars have good fruit quality. There was little variation in fruit color in the two years evaluated. Blueberry cultivars showed the staining characteristics and physical and chemical attributes of quality compatible to blueberry from other traditional regions. Under mild winter conditions, young plants of rabbiteye blueberry cultivars, Climax, Delite, Bluegem and Powderblue, are the most productive, while the highbusch cultivars bear few fruits.

    Full Text Available Esterase isozymes were used to detected substrate-preference polymorphism in twenty cultivars of Manihot esculenta, and to show cultivar-specific variation of this species. A relatively complex extraction solution of proteins from leaves was needed to show a larger number of esterase isozymes. Similarity between cultivars from six groups ranged from 51 to 96%. The cultivars identified by the same name seemed to be biochemically different regarding esterase isozymes. Esterase isozyme electrophoretic patterns could, therefore, be used to discriminate the cultivars identified by the same name, and to monitor the vegetative propagation of cultivars maintained in the germplasm collection. In breeding strategies, isoesterase analysis could be used to avoid intercrossing between the similar genotypes.Isoenzimas esterases foram usadas no presente estudo, para detectar polimorfismos específicos para diferentes substratos em vinte cultivares de Manihot esculenta, e para mostrar variações específicas de cultivares nesta espécie.

Foi necessário a utilização de uma solução de extração de proteínas relativamente mais complexa, para evidenciar um maior número de isoenzimas esterases. A similaridade entre os cultivares variou de 51 a 96%. Cultivares identificados pelo mesmo nome parecem ser bioquimicamente diferentes para as isoenzimas esterases. Os padrões eletroforéticos das isoesterases podem, portanto, serem usados para discriminar os cultivares que são identificados pelo mesmo nome, e para monitorar a propagação vegetativa dos cultivares mantidos na coleção de germoplasma.

    Abstract: This paper compares four Colombian blackberry cultivars- (Rubus sp.) light compensation points, leaf area, chlorophyll concentration and photosynthetic capacity. Time can be saved and efficiency improved by adapting different cultivars to differing luminosity once these parameters have been determined and established. The four cultivars involved were -Guarne-, -San Antonio-, -Sara 3- and -Pacho 2- forming part of Corpoica-s blackberry collection at the Sena farm in Manizales. The results revealed that all four cultivars had different light compensation points. They also showed that net photosynthesis varied amongst cultivars, even when grown in the same environmental conditions and that total chlorophyll and leaf area may be used as indicators of response to the conditions being evaluated.

    To study the performance of different tomato cultivars under organic and inorganic regimes an experiment was conducted at New Developmental Farm, The University of Agriculture, Peshawar, Pakistan during the summer 2013-14. The experiment was laid out in RCBD with split plot arrangement having four replications. Organic regimes (FYM, poultry manure and mushroom compost) and inorganic (NPK) regimes were allotted to main plot, while cultivars (Roma VF, Roma, Super Classic, Bambino and Rio Grande) were subjected to sub plots. Organic and Inorganic regimes significantly (P ≤ 0.01) influenced all the studied attributes of tomato cultivars. Among different cultivars, Roma gave maximum plant survival (93.8 percentage), number of leaves plant (84.1), number of flower inflorescence (5.4), number of fruits inflorescence (4.3), number of fruit plant (25.4), fruit size (63.9 cm) fruit weight plant (9.1 kg) and total yield (22.9 t ha). However, it was closely followed by cultivar Rio Grande for number of leaves plant (79.6), number of flower inflorescence (5.1), number of fruits inflorescence (4.0) and number of fruits plant (24.9). Cultivar Super Classic produced minimum number of leaves plant (67.7), flower inflorescence (4.8), fruit size (60.6 cm), fruit weight plant (8.6 kg) and total yield (21.7 t ha). Similarly, highest plant survival (90.0 percentage), number of flower inflorescence (5.1), number of fruits inflorescence (4.0), number of fruit plant (25.4), fruit size (62.4 ml), fruit weight plant (8.90 kg) and total yield (22.9 t ha) were recorded in plants provided with organic conditions Roma cultivar performed better than other cultivars under the agro climatic condition of Peshawar followed by cultivar Rio Grande. Therefore, organic tomato production, and these two cultivars are recommended to be grown in Peshawar area. (author)

    Background Green tea has various health promotion effects. Although there are numerous tea cultivars, little is known about the differences in their nutraceutical properties. Metabolic profiling techniques can provide information on the relationship between the metabolome and factors such as phenotype or quality. Here, we performed metabolomic analyses to explore the relationship between the metabolome and health-promoting attributes (bioactivity) of diverse Japanese green tea cultivars. Methodology/Principal Findings We investigated the ability of leaf extracts from 43 Japanese green tea cultivars to inhibit thrombin-induced phosphorylation of myosin regulatory light chain (MRLC) in human umbilical vein endothelial cells (HUVECs). This thrombin-induced phosphorylation is a potential hallmark of vascular endothelial dysfunction. Among the tested cultivars, Cha Chuukanbohon Nou-6 (Nou-6) and Sunrouge (SR) strongly inhibited MRLC phosphorylation. To evaluate the bioactivity of green tea cultivars using a metabolomics approach, the metabolite profiles of all tea extracts were determined by high-performance liquid chromatography-mass spectrometry (LC-MS). Multivariate statistical analyses, principal component analysis (PCA) and orthogonal partial least-squares-discriminant analysis (OPLS-DA), revealed differences among green tea cultivars with respect to their ability to inhibit MRLC phosphorylation. In the SR cultivar, polyphenols were associated with its unique metabolic profile and its bioactivity. In addition, using partial least-squares (PLS) regression analysis, we succeeded in constructing a reliable bioactivity-prediction model to predict the inhibitory effect of tea cultivars based on their metabolome. This model was based on certain identified metabolites that were associated with bioactivity. When added to an extract from the non-bioactive cultivar Yabukita, several metabolites enriched in SR were able to transform the extract into a bioactive extract

    1995-01-01

    A preliminary experiment was conducted to evaluate the radiosensitivity of common bean (Phaseolous vulgaris L.), cultivar to gamma rays from a 60 Co source. Sets of seeds (60 seed/sample) irradiated with 50, 100, 150, 200, and 250 Gy, were compared to a control without irradiation (0 Gy), under greenhouse conditions. The radiosensitivity was evaluated through seedling height reduction, determined at 15 days after emergence (DAE), and also through seedling survival, root length, and dry matter production of leaves, shoots and roots. Seedling height was significantly reduced for the treatments with 150 and 250 Gy, in relation to the control. The dose causing reduction of 50% seedling height was between 150 and 200 Gy. Survival rates corresponding to these doses, were, respectively, 85% and 60%. Root length and dry matter of leaves, shoots and roots, were inversely related to the doses.

The Danish apple (Malus domestica L.) gene bank collection...... understanding of the link between phenotypes and the underlying gene-tic background which is crucial in plant breeding. We found a considerable genetic diversity in the collection and no genetic structure. We exposed a high number of accessions in admix and revealed several putative cultivar parentages, never......, including several rare alleles. Using historical gene bank records, including aroma volatile analysis, sugar and acid data and other fruit- and tree character records, we established genotype-phenotype relationships, performing a genome-wide association study.

    Phytotron studies were conducted to determine the intraspecific variation in sensitivity of rice (Oryza sativa L.) to enhanced UVB and to test the hypothesis that rice cultivars originating from regions with higher ambient UVB radiation are more tolerant to enhanced UVB. Out of the 188 rice cultivars (from various rice growing regions and ecosystems) tested, 143 had significantly reduced plant height, 52 had smaller leaf area, 61 had lower plant dry weight and 41 had less tiller number under elevated UVB radiation (13.0 kJ m −2 day −1 ) for 3 weeks. Six cultivars showed significant positive growth response to enhanced UVB radiation, although the mechanism is not clear at present. These six cultivars were from the summer rice crop of Bangladesh and from high elevation rice areas where prevailing UVB radiation is most likely to be greater. However, there was no correlation between the dry matter changes under enhanced UVB and the ambient UVB level at the origin of the cultivar across the 188 cultivars tested. Therefore, cultivars originating from regions with higher ambient UVB are not necessarily more tolerant to enhanced UVB radiation. (author)

    1996-01-01

    Twenty cultivars of cowpea, Vigna unguiculata, adapted to the Nigerian ecologies were screened to identify cultivars which can give high and sustainable yields when grown on soils with low available phosphorus in a sub-humid climate. Some cultivars including TVX3236, AFB1757, Ogunfowokan and K-28 gave three to four times higher grain yields than the other cultivars at zero phosphorus supply. While phosphorus application reduced grain yield in most of the cultivars with marked reduction in the higher yielding cultivars, low yielding cultivars tended to show some yield increase. Phosphorus use efficiency of the roots, stem or leaves was not significantly correlated with grain yield when 60 KgP/ha was applied. Reduction in yield due to phosphorus application might be due to induced Zn deficiency as Zn supply in these soils has been found to be inherently low. High grain yielding capacity without fertilizer phosphorus application was generally positively correlated with high vegetative shoot dry matter production. However, no clear relationship could be found between grain yield and root dry matter at maturity. It is concluded that selection for phosphorus efficiency in cowpea can substantially contribute to higher cowpea productivity and the farmers income on soils low in available phosphorus in the sub-humid areas of Nigeria.

    Full Text Available ABSTRACT: Information on the production performance of blackberry in less colder regions are fundamentals to the expansion of the cultivated area and extension of management practices for cultivars adapted to climate conditions in Brazil. The research was carried out with the aim to evaluate the productive performance of different blackberries cultivars in altitude region of 1,387m with mild temperatures, situate at 18º14’56”S, 43º36’0”W, in Minas Gerais State, Brazil. It was carried during the seasons 2013/2014, 2014/2015 and 2015/2016. The blackberry cultivars evaluated were the following ones ‘Brazos’, ‘Guarani’, ‘Tupy’ and ‘Xavante’. Flowering and harvesting of cultivars were evaluated as well as climatological data of the area in order to relate the number of hours of accumulated cold less than 13°C, 10°C and 7.2°C with production and crop time. To determine the production, the mass of blackberries harvested per plant was measured. Production of blackberry cultivars was extended in altitude region with similar productivity to the other producing regions in Brazil. Productive performance of the cultivars varied according to the accumulation of cold hours with mild temperatures that occurred in cultivation region. ‘Brazos’, ‘Guarani’, ‘Tupy’ and ‘Xavante’ showed good adaptation, being ‘Brazos’ the cultivar most productive.

    Tropical soils are particularly vulnerable to fertility losses due to their low capacity to retain organic matter and mineral nutrients. This urges the development of new agricultural practices to manage mineral nutrients and organic matter in a more sustainable way while relying less on fertilizer inputs. Two methods pertaining to ecological engineering and agroecology have been tested with some success: (1) the addition of biochar to the soil, and (2) the maintenance of higher earthworm densities. However, modern crop varieties have been selected to be adapted to agricultural practices and to the soil conditions they lead to and common cultivars might not be adapted to new practices. Using rice as a model plant, we compared the responsiveness to biochar and earthworms of five rice cultivars with contrasted selection histories. These cultivars had contrasted responsivenesses to earthworms, biochar, and the combination of both. The mean relative increase in grain biomass, among all treatments and cultivars, was 94% and 32%, respectively, with and without fertilization. Choosing the best combination of cultivar and treatment led to a more than fourfold increase in this mean benefit (a 437% and a 353% relative increase in grain biomass, respectively, with and without fertilization). Besides, the more rustic cultivar, a local landrace adapted to diverse and difficult conditions, responded the best to earthworms in terms of total biomass, while a modern common cultivar responded the best in term of grain biomass. This suggests that cultivars could be selected to amplify the benefit of biochar- and earthworm-based practices. Overall, selecting new cultivars interacting more closely with soil organisms and soil heterogeneity could increase agriculture sustainability, fostering the positive feedback loop between soils and plants that has evolved in natural ecosystems.

    Full Text Available The development of new cultivars is the ultimate goal of breeding programs and is the result of many years of hard work and dedication of breeders and their teams. An important part of the process, often neglected by geneticists, is the stage from recommendation to the production of breeder seed (post-breeding. This paper discusses the role of the breeder in the recommendation, registration, protection and marketing of new cultivars. The breeder’s active participation in all phases of post-breeding is fundamental to ensure that the cultivar reaches farmers quickly and can provide the benefits expected by society

    Solid-stemmed spring wheat cultivars ( Triticum aestivum L.) are resistant to the stem sawfly ( Cephus cinctus Nort.) and lodging. Anthers of 24 spring wheat cultivars with varying content of pith in the stem were used in the experiment. All were classified into three groups: solid, medium-solid and hollow stems. There was considerable influence of the cultivar on callus formation and green plant regeneration. The highest efficiency of green plant regeneration (24%) was observed for the solid-stemmed AC Abbey cultivar. There was no regeneration from the explants of four cultivars: CLTR 7027, Alentejano, Marquis and Bombona. Principal component analysis showed no differences between the cases under observation (callus induction and green plant regeneration) in their response to pre-treatment temperatures (4 and 8°C). The examination of the effects of various auxin types in the induction medium on callus formation and green plant regeneration revealed that the strongest stimulation of these processes was observed in the C17 medium with 2,4-D and dicamba. The efficiency of callus formation and green plant regeneration was greater in solid-stemmed cultivars than in hollow-stemmed cultivars.

    The chemical composition, physicochemical, functional and sensory properties of mucilages, extracted from seven Italian flax cultivars, were evaluated. All samples were composed of neutral and acidic sugars, with a low protein content. From the NMR data, a rhamnogalacturonan backbone could be inferred as a common structural feature for all the mucilages, with some variations depending on the cultivar. All the suspensions showed a poor stability, which was consistent with a low zeta potential absolute value. The viscosity seemed to be positively correlated with the neutral sugars and negatively with the amount of proteins. Functional properties were dependent on the cultivar. The sensory analysis showed that most mucilages are tasteless. All these outcomes could support the use of flaxseed mucilages for industrial applications. In particular, Solal and Festival cultivars could be useful as thickeners, due to their high viscosity, while Natural, Valoal and Kaolin as emulsifiers for their good surface-active properties.

    A cultivar by seed rate trial was conducted in 1994-1995 crop seasons at Njoro, Kenya. Yield results were found to be significant (P > 0.01) for year, variety, seed rate and year by seed rate interaction. Test weight was highly significant (P -1 were grouped together for significantly higher yields (A) whereas seed rates 85 and 50 kg ha -1 had lower significant yields (B and C respectively). The same grouping was repeated for test weight. There was no significant cultivar by seed rate interaction and no cultivar, specific seed rate. However, since seed rates 245, 205, 165 and 125 kg ha -1 were grouped together, the lowest seed rate, 125 kg ha -1 can be recommended as the optimum seed rate for the above cultivars, as higher seed rates do not give significantly higher yields or higher test weights

    2013-12-01

    Full Text Available Six cultivars of radish (Raphanus sativus were tested for their usefulness in radish cytokinin bioassay by the method of Letham (1971. The best cultivar was found to be 'Sopel Lodu' which responds well to both zeatin and 2iP over a wide range of concentrations. The fresh weight of cotyledons increased at most by 71.5% (if treated with zeatin or 101.0% (if treated with 2iP compared to untreated cotyledons. This cultivar is also sensitive to the partially purified cytokinin-like fraction isolated from the pine (Pinus silvestris cambial region. The cultivar 'Sopel Lodu' is therefore proposed to be a suitable plant for cytokinin bioassays.

    Full Text Available A study conducted over a period of two years in a Western Serbian valley included in situ identification of autochthonous plum cultivars. Observation and recording of their phenological and pomological traits were performed using IBPGR and UPOV methodologies. Fifteen cultivars derived from Prunus domestica L. and two cultivars derived from P. insititia L. were identified. Flowering started between 24 March and 7 April and fruit ripening between 12 July (Petrovača and 16 September (Trnovača. Fruit weight ranged from 6.79± 0.018 to 36.62± 0.251 g and stone weight from 0.14± 0.002 to 1.95± 0.023 g. The cultivars were classified as being extremely small in terms of fruit size. Rounded fruit shape and light-yellow ground colour were dominant. Skin colour ranged from amber to black. Yellow green was a dominant flesh colour and medium flesh firmness predominated. The fruits of the above cultivars could be processed, particularly into plum brandy, or they could be used fresh or dried. The selected plum cultivars can be used both in breeding programmes and as rootstocks as well as in further disease-related systematic studies under field and laboratory conditions.

    Full Text Available Sour cherry (Prunus cerasus in the genus Prunus in the family Rosaceae is one of the most popular stone fruit trees worldwide. Of known sour cherry cultivars, the Schattenmorelle is a famous old sour cherry with a high amount of fruit production. The Schattenmorelle was selected before 1650 and described in the 1800s. This cultivar was named after gardens of the Chateau de Moreille in which the cultivar was initially found. In order to identify new genes and to develop genetic markers for sour cherry, we performed a transcriptome analysis of a sour cherry. We selected the cultivar Schattenmorelle, which is among commercially important cultivars in Europe and North America. We obtained 2.05 GB raw data from the Schattenmorelle (NCBI accession number: SRX1187170. De novo transcriptome assembly using Trinity identified 61,053 transcripts in which N50 was 611 bp. Next, we identified 25,585 protein coding sequences using TransDecoder. The identified proteins were blasted against NCBI's non-redundant database for annotation. Based on blast search, we taxonomically classified the obtained sequences. As a result, we provide the transcriptome of sour cherry cultivar Schattenmorelle using next generation sequencing.

    Full Text Available In potato breeding, it is difficult to improve the traits of interest at the tetraploid level due to the tetrasomic inheritance. A promising alternative is diploid breeding. Thus it is necessary to assess the genetic diversity of diploid potato germplasm for efficient exploration and deployment of desirable traits. In this study, we used SSR markers to evaluate the genetic diversity of diploid potato cultivars. To screen polymorphic SSR markers, 55 pairs of SSR primers were employed to amplify 39 cultivars with relatively distant genetic relationships. Among them, 12 SSR markers with high polymorphism located at 12 chromosomes were chosen to evaluate the genetic diversity of 192 diploid potato cultivars. The primers produced 6 to 18 bands with an average of 8.2 bands per primer. In total, 98 bands were amplified from 192 cultivars, and 97 of them were polymorphic. Cluster analysis using UPGMA showed the genetic relationships of all accessions tested: 186 of the 192 accessions could be distinguished by only 12 pairs of SSR primers, and the 192 diploid cultivars were divided into 11 groups, and 83.3% constituted the first group. Clustering results showed relatively low genetic diversity among 192 diploid cultivars, with closer relationship at the molecular level. The results can provide molecular basis for diploid potato breeding.

    Four wheat (Triticum aestivum L.) cultivars, namely condor, El-Nellene, Wadi El Neil and Debeira were characterized on biochemical and molecular bases. The biochemical ones were protein-banding patterns, using sodium dodecylsulfate-polyacrylamide gel electrophoresis (SDS-PAGE), and isozymes to identify the biochemical genetic fingerprint of the four cultivars. Water-soluble protein-banding pattern showed no polymorphisms among the tested cultivars. The data from starch gel electrophoresis of enzymes, malate dehydrogenase (MDH), esterase (EST) and acid phosphate (ACPH) showed that the cultivars are monomorphic. Further trials to identify the molecular genetic fingerprints of the studied cultivars were carried out using RAPD-PCR twenty-five primers were tested to perform. RAPD-PCR analysis. From the PCR products, a phylogenetic map, i.e, dendrogram, was constructed for the studied cultivars which depicted tow groups. The first group contained Wadi El Neil and Deberia with 48.4% similarity, and the second group contained Condor and El Neileen with 100% similarity. There was no similarity between Condor and Debeira (100% dissimilarity). Therefor, these data can be used subsequently for genetic engineering research and for wheat breeding programmes in the Sudan.(Author)

    Full Text Available The increased consumption of acerola in Brazil was triggered because it is considered as a functional food mainly for its high ascorbic acid content, but the fruit also has high nutritional value, high levels of phenolic compounds, total antioxidant activity, anthocyanins and carotenoids in its composition. The objective was to evaluate the chemical, physical-chemical and antioxidant activity of eight varieties of acerola tree. The acerolas used in the research were the harvest 2015, 8 varieties: BRS 235 - Apodi, Mirandópolis, Waldy - CATI 30, BRS 238 - Frutacor, Okinawa, BRS 236 - Cereja, Olivier and BRS 237 - Roxinha, from the Active Bank Germplasm APTA Regional Alta Paulista in Adamantina - SP. Avaluated the following attributes: pH, titratable acidity, soluble solids, reducing sugar, instrumental color, ascorbic acid, total phenolics, flavonoids and antioxidant activity. The design was completely randomized, 8 varieties and 3 replications of 20 fruits each. Acerola fruit of the analyzed varieties prove to be good sources of phenolic compounds and antioxidant activity, ensuring its excellent nutritional quality relative to combat free radicals. The variety BRS 236 - Cereja presents higher ascorbic acid content, antioxidant activity and phenolic compounds, and the lowest value for flavonoid, which was higher than the other cultivars, especially Olivier and Waldy CATI-30.

    Two cultivars Buram-3-ho (susceptible) and CR-Hagwang (moderate resistant) of kimchi cabbage seedlings showed differential defense responses to anthracnose (Colletotrichum higginsianum), black spot (Alternaria brassicicola) and black rot (Xanthomonas campestris pv. campestris, Xcc) diseases in our previous study. Defense-related hormones salicylic acid (SA), jasmonic acid (JA) and ethylene led to different transcriptional regulation of pathogenesis-related (PR) gene expression in both cultivars. In this study, exogenous application of SA suppressed basal defenses to C. higginsianum in the 1st leaves of the susceptible cultivar and cultivar resistance of the 2nd leaves of the resistant cultivar. SA also enhanced susceptibility of the susceptible cultivar to A. brassicicola. By contrast, SA elevated disease resistance to Xcc in the resistant cultivar, but not in the susceptible cultivar. Methyl jasmonate (MJ) treatment did not affect the disease resistance to C. higginsianum and Xcc in either cultivar, but it compromised the disease resistance to A. brassicicola in the resistant cultivar. Treatment with 1-aminocyclopropane-1-carboxylic acid (ACC) ethylene precursor did not change resistance of the either cultivar to C. higginsianum and Xcc. Effect of ACC pretreatment on the resistance to A. brassicicola was not distinguished between susceptible and resistant cultivars, because cultivar resistance of the resistant cultivar was lost by prolonged moist dark conditions. Taken together, exogenously applied SA, JA and ethylene altered defense signaling crosstalk to three diseases of anthracnose, black spot and black rot in a cultivar-dependent manner.

    Three sweet potato cultivars (TNG57, TNG66, and TNG73), provided by the Taiwanese Agricultural Research Institute (TARI), were stored at either 15 °C or under ambient conditions (23.8 ~ 28.4 °C and 77.1 ~ 81.0 % of relative humidity). Sweet potato roots were randomly chosen from each replicate and evaluated for measurement of weight loss, sugar content analysis, and sprouting after 0, 14, 24, 48, 56, 70, 84, and 98 days of storage. Fresh sweet potato roots were baked at 200 °C for 60 min then samples were taken for sugar analysis. After 14 days of ambient condition storage, the sprouting percentages for TNG57, TNG66, and TNG73 were 100, 85, and 95 % respectively. When sweet potatoes were stored at 15 °C, the weight loss became less and no sweet potato root sprouted after 14 days of storage. Because manufacturers can store sweet potatoes at 15 °C for almost 2 month without other treatments, the supply capacity shortage in July and September can be reduced. The total sugar content slowly increased along with increasing the storage time. After baking, the total sugar content of sweet potatoes significantly increased due to the formation of maltose. Maltose became the major sugar of baked sweet potatoes. Raw sweet potatoes stored at 15 °C had higher total sugar contents after baking than those stored under ambient conditions. Raw sweet potatoes were recommended to be stored at 15 °C before baking.

  9. Genealogy of wine grape cultivars: "Pinot" is related to "Syrah".

    2006-08-01

    Since the domestication of wild grapes ca 6000 years ago, numerous cultivars have been generated by spontaneous or deliberate crosses, and up to 10 000 are still in existence today. Just as in human paternity analysis, DNA typing can reveal unexpected parentage of grape cultivars. In this study, we have analysed 89 grape cultivars with 60 microsatellite markers in order to accurately calculate the identity-by-descent (IBD) and relatedness (r) coefficients among six putatively related cultivars from France ("Pinot", "Syrah" and "Dureza") and northern Italy ("Teroldego", "Lagrein" and "Marzemino"). Using a recently developed likelihood-based approach to analyse kinship in grapes, we provide the first evidence of a genetic link between grapes across the Alps: "Dureza" and "Teroldego" turn out to be full-siblings (FS). For the first time in grapevine genetics we were able to detect FS without knowing one of the parents and identify unexpected second-degree relatives. We reconstructed the most likely pedigree that revealed a third-degree relationship between the worldwide-cultivated "Pinot" from Burgundy and "Syrah" from the Rhone Valley. Our finding was totally unsuspected by classical ampelography and it challenges the commonly assumed independent origins of these grape cultivars. Our results and this new approach in grape genetics will (a) help grape breeders to avoid choosing closely related varieties for new crosses, (b) provide pedigrees of cultivars in order to detect inheritance of disease-resistance genes and (c) open the way for future discoveries of first- and second-degree relationships between grape cultivars in order to better understand viticultural migrations.

    Full Text Available The implementation of silvopastoral systems (SSP is a management option that gives good results for animal production, but the shading of the trees can alter production, growth behavior and morphological composition of the forage. The aim of the study was to evaluate the morphological composition of Urochloa brizantha cultivars Marandu and Piatã under natural light and artificial shading of 30 and 60%. The experiment was conducted at FMVZ - UNESP, Botucatu. The experimental design was a randomized block in factorial arrangement 3 x 2 (three shading levels: 0, 30 and 60% and two cultivars: Marandu and Piatã with three replications and repeated measures in time (3 cuts. Sample collection occurred when the cultivars reached in 35 cm of height. Significant effects (P<0.05 of cultivar x shade x cut interaction were observed on the dry matter production of leaves and stems (Table 1. The higher production of leaves and stems (P<0.05 occurred for Piatã under natural light in the third cut (3731 and 1920 kg/ha, respectively. The absence of shade favored greater leaf production, 35 and 27% higher than the reductions of 30 and 60% respectively. The increment of stems for Piatã under natural light is related to the increase of inflorescences. The leaf:stem ratio was higher (P< 0.05 for Marandu under natural light (Table 2, with effect from the interaction cultivar x brightness level. A significant effect (P<0.05 cultivar x level of light reduction for light interception parameter was detected (Table 2. For Marandu, light levels were not influenced (P<0.05 light traps (Table 2, being close to the 95% criterion used for pasture management, justified by the collection at the point of balance between forage productivity and nutritional content, and strong relationship with high input grazing. The results indicate that the morphological composition of the cultivars is modified by reducing the light intensity.

    Full Text Available Wheat (Triticum aestivum is one of the most important food staples in the south of Brazil. Understanding genetic variability among the assortment of Brazilian wheat is important for breeding. The aim of this work was to molecularly characterize the thirty-six wheat cultivars recommended for various regions of Brazil, and to assess mutual genetic distances, through the use of microsatellite markers. Twenty three polymorphic microsatellite markers (PMM delineated all 36 of the samples, revealing a total of 74 simple sequence repeat (SSR alleles, i.e. an average of 3.2 alleles per locus. Polymorphic information content (PIC value calculated to assess the informativeness of each marker ranged from 0.20 to 0.79, with a mean of 0.49. Genetic distances among the 36 cultivars ranged from 0.10 (between cultivars Ocepar 18 and BRS 207 to 0.88 (between cultivars CD 101 and Fudancep 46, the mean distance being 0.48. Twelve groups were obtained by using the unweighted pair-group method with arithmetic means analysis (UPGMA, and thirteen through the Tocher method. Both methods produced similar clusters, with one to thirteen cultivars per group. The results indicate that these tools may be used to protect intellectual property and for breeding and selection programs.

    Full Text Available Introduction: Toxic soil concentrations of the essential micronutrient boron (B represent major limitations to crop production worldwide. Plants have a range of defense systems that might be involved in their affinity to resist and tolerate nutrients stress.Materials and methods: The experiments were carried out to study the differential responses in five wheat cultivars to boron toxicity. Results: The fresh and dry matter yield of the test wheat cultivars showed marked decrease as the concentration of boron was increased. Elevated concentration of boron had a notable inhibitory effect on the biosynthesis of pigments fractions in the test wheat cultivars as severely as dry matter gain. The adverse concentration effects of boron on some metabolic responses were clearly displayed by shoot and root systems, exhibited in the elevated rates of proline, hydrogen peroxide and malondialdehyde formation. Potassium leakage was severely affected by boron-stress in some cultivars at all tested concentrations, while in some others a moderate damage was manifested only at the higher boron concentrations.Conclusions: Sakha 93 out of all the different cultivars investigated was found to display the lowest sensitivity to boron-stress, while Gemmeza 9 was the most sensitive one.

    Pecan (Carya illinoensis) has been introduced to East China for over one hundred years, but its planting is still only occurring at a small scale. The key limiting factor is its low yield. To enhance the yield pecan in East China, two pecan cultivars, Mahan and Western, were examined. Twenty traits describing phasic development, yield, nut quality, and cultural practice were investigated. We found that pecan cultivar Mahan gives a higher yield and nut quality than cultivar Western. We recommend interplanting of cultivar Pawnee to act as a pollinator tree. Appropriate cultivation practices that can be implemented to enhance fruit yield of cultivars Mahan and Western include soil-applied paclobutrazol (PBZ) at certain concentrations, pinching, and supplementary pollination. For example, the addition of 1.25 g/m 2 of PBZ inhibits pecan branch growth and stimulates short bearing branches, which promotes fruit yield. We found that soil-applied PBZ reached optimal performance 82 days after application. A pinching length of 40 cm resulted in a fruit yield increase. In addition, grafting and transplantation may promote male flowering, but delays female flowering. These cultural practices may provide insights that can be used to improve pecan cultivation in East China.

    Full Text Available Xylocarpus granatum J. Koenig is one of the most widespread core component species of mangrove forests in the Indo-West Pacific (IWP region, and as such is suitable for examining how genetic structure is generated across spatiotemporal scales. We evaluated the genetic structure of this species using maternally inherited chloroplast (cp and bi-parentally inherited nuclear DNA markers, with samples collected across the species range. Both cp and nuclear DNA showed generally similar patterns, revealing three genetic groups in the Indian Ocean, South China Sea (with Palau, and Oceania, respectively. The genetic diversity of the Oceania group was significantly lower, and the level of population differentiation within the Oceania group was significantly higher, than in the South China Sea group. These results revealed that in addition to the Malay Peninsula—a common land barrier for mangroves—there is a genetic barrier in an oceanic region of the West Pacific that prevents gene flow among populations. Moreover, demographic inference suggested that these patterns were generated in relation to sea level changes during the last glacial period and the emergence of Sahul Shelf which lied northwest of Australia. We propose that the three genetic groups should be considered independent conservation units, and that the Oceania group has a higher conservation priority.

    Full Text Available Italy is one of the main apple producers in Europe, primarily intended for fresh consumption, both in the domestic and foreign markets. Fruit yield and quality depends on the cultivar, rootstock, and management practices, such as the fertilization and irrigation adopted in the orchard. This review aims at reporting the main apple cultivars and rootstocks, the management of fertilization and irrigation, as well as their adaptation to apple tree orchards in Italy. The programs for genetic improvement carried out in this country involved the selection of apple tree cultivars and rootstocks which enable a high fruit yield and quality, in order to meet the requirements from the consumer market. In the fertilization and irrigation management, nutrients and water are supplied in amounts next to the actual need of the plants, providing an adequate nutrition, a satisfactory yield, and high quality fruits, besides preventing, whenever possible, nutrients and water losses in the environment.

    Full Text Available The objective of this work was to evaluate the occurrence of polyembryony in the mango cultivars Manila and Ataulfo, and to determine whether seedlings cultured in vitro are zygotic or nucelar. Percentage of polyembryony was calculated and the number of embryos in 100 seeds of each cultivar was recorded. 'Manila' exhibited 97% polyembryony with 3.4 embryos per seed, while 'Ataulfo' had 95% polyembryony with 3.2 embryos per seed. Later, 20 seeds of each cultivar were established in vitro, and it was analyzed those in which all embryos germinated (12 seeds from 'Manila' and 7 from 'Ataulfo'. DNA was extracted from seedling leaf tissue, and its origin was identified with 14 RAPD primers. The polymorphic markers recognized the seedlings of sexual origin in seven of nine 'Manila' polyembryonic seeds, and in four of seven 'Ataulfo' ones. Also, in polyembryonic seeds not all zygotic seedlings were produced by small embryos located at the micropyle.

    Tea (Camellia sinensis L.) leaf contains a large amount of catechins (a group of very active flavonoids) which contribute to major quality attributes of black tea. Based on morphological characters tea plants were classified as Assam, China, and Cambod varieties. The present study is an attempt for biochemical fingerprinting of the tea varieties based on catechin composition in green leaf of cultivars grown in Northeast India. Assam variety cultivars contained the highest level of catechins followed by Cambod and China. The average catechin contents were 231 ± 7 mg g(-1), 202 ± 5 mg g(-1), and 157 ± 4 mg g(-1) of dry weight of green leaf for Assam, Cambod, and China cultivars, respectively. Among the individual catechins the variations in epigallocatechin gallate (EGCG) and epigallocatechin (EGC) were the most prominent among the varieties. High EGC content was found to be a characteristic of Assam variety which was further corroborated through multivariate analysis.

    2004-01-01

    Full Text Available The performance of bean lines brought forth in breeding programs or of cultivars in use can be affected by environmental variability. The adaptability and stability of grain yield of 18 common bean cultivars and lines in 23 environments (combinations of seasons, years and locations were evaluated in the State of São Paulo, Brazil. 'IAC-Carioca' and 'IAC-Carioca Eté' were used as standard cultivars for the carioca grain type, while 'FT-Nobre' and 'IAC-Una' represented the standard for black grains. The experiment was set up in a randomized complete block design with four replications and plots consisting of two, two central five meters rows flanked by border rows. Stability parameters were estimated by the methods Maximum Yield Deviations (MYD and by the Additive Main Effects and Multiplicative Interaction Analysis (AMMI. For the identification of the most stable cultivars, the two methods led to consistent results, although by MYD the highest stability was always associated to the highest yield. 'MAC-733327' and 'LP 9637' were the most suitable cultivars and lines for the joint seasons, while 'LP 9637' and 'FT-Nobre' were the most suitable for the dry season. The MYD method combined a simple procedure, easiness of result interpretation, uniqueness of parameters, and association between stability and yield. On the other hand, the AMMI method simplified the identification of stable cultivars by visual inspection, also providing information on the environments. However, the complex nature which combines uni-and multivariate techniques hampers its widespread use in breeding programs.

    Full Text Available Information on genetic diversity is essential to the characterization and utilization of germplasm. The genetic diversity of twenty-two sweet corn cultivars (seventeen open-pollinated varieties, OPV, and five hybrids, H was investigated by applying simple sequence repeat markers. A total of 257 primers were tested, of which 160 were found to be usable in terms of high reproducibility for all the samples tested; 45 were polymorphic loci, of which 30 were used to assess the genetic diversity of sweet corn cultivars. We detected a total of 86 alleles using 30 microsatellite primers. The mean polymorphism was 82 %. The highest heterozygosity values (Ho = 0.20 were found in the PR030-Doce Flor da Serra and BR427 III OPVs, whereas the lowest values (0.14 were recorded in the MG161-Branco Doce and Doce Cubano OPVs. The polymorphism information content ranged from 0.19 (Umc2319 to 0.71 (Umc2205. The analysis of molecular variance revealed that most of the genetic variability was concentrated within the cultivars of sweet corn (75 %, with less variability between them (25 %. The consensus tree derived from the neighbor-joining (NJ algorithm using 1,000 bootstrapping replicates revealed seven genetically different groups. Nei’s diversity values varied between 0.103 (Doce do Hawai × CNPH-1 cultivars and 0.645 (Amarelo Doce × Lili cultivars, indicating a narrow genetic basis. The Lili hybrid was the most distant cultivar, as revealed by Principal Coordinates Analysis and the NJ tree. This study on genetic diversity will be useful for planning future studies on sweet corn genetic resources and can complement the breeding programs for this crop.

    Full Text Available The purpose of this research was to study the behaviour of two new Romanian thorn blackberry cultivars DAR 24 and DAR 8 in process of micropropagation, compared with Darrow cultivar usually commercially micropropagated in our laboratory. Due to several drawbacks of the conventional propagation of Rubus, the efficiency of micropropagation was tested in order to obtain high quality planting material and to introduce rapidly these new cultivars in a certification program. Thorn blackberry cultivars DAR 8 and DAR 24 with resistance to winter colds was successfully micropropagated. Blackberry plants were found without virus infection after biological and ELISA tests. Axillary buds from the branches in full growth were used as the initial explants. After four weeks of growth, aseptic cultures was established on MS basal mineral salts, LS vitamins with 0.3 mg/l BAP, 0.1mg/l GA3 and 0.001mg/l NAA. The rate of successfully established cultures was on average 65.11%. Good proliferation of the regenerated shoots was obtained on the same medium composition used for initiation phase, whereas medium MS with mineral salts reduced to ½ and LS vitamins with 0.1 mg/l IBA and 0.1 mg/l GA3 was used in the rooting phase. Dar 24 and Dar 8 cultivars responded by good rates of micropropagation on medium culture B as compared to control Darrow cultivar, even if the obtained shoots length was lower than on medium A. The statistical analysis reveled that the highest MR (20.66 plantlets/explant was obtained for Dar 24. In this case the length of shoots was 1.92 cm. The highest rooting percentages (over 85% were obtained with shoots multiplied on medium B. High quality of rooted plants induced a high percentage of acclimatization of cultivar Dar 8, 86.36% under mist system in green house whereas the percentage of acclimatization of cultivar Dar 24 was lower, 51.85%.

    Estimation of DNA amounts (in arbitrary units) in two genera, two species, and three cultivars of one species, permits comparison between them and indicates that the biggest difference is between the two genera, Lactuca and Cichorium; but that the difference between the cultivars of Lactuca sativa is greater than the difference between Lactuca serriola and the mean for Lactuca sativa. Lactuca serriola is a presumed ancestor of Lactuca sativa. The most radiosensitive species, L. serriola, has slightly less DNA and smaller nuclear volume than the next most sensitive, L. sativa cult.

    Five new cultivars of common beans (Phaseolus vulgaris) recently released were analyzed for their proximate chemical composition and protein biological quality. The crude protein content in these cultivars ranged from 21.9 percent in cultivar Arroz 3 to 26.9 percent in cultivar Tórtola Diana (dry matter basis). Rats fed cultivar Tórtola INIA gained more weight, had a higher protein intake and registered higher PER and NPR than Tórtola corriente. On the other hand, rats consuming cultivars Arroz 3 and Fleetwood had lower weight gain, lower protein intake and lower PER and NPR than cultivar Coscorrón corriente. However, all these cultivars have a relatively good protein value as compared to other plant protein sources.

    Malvasia is a common name for different grape cultivars that have long been grown in Spain. In many cases, these cultivars are noted as being aromatic, sweet, and similar to Muscat in flavour. However, not all grapes that share this name exhibit these characteristics. This study compares the Malvasia cultivars in the Spanish Denominations of Origin with those grape cultivars grown in the grapevine collection of El Encin (Alcala de Henares, Spain) using morphological, iso enzymatic, and micro satellite analysis as well as a large bibliographic search of the studied cultivars. Despite their Malvasia denomination, some cultivars have been identified as synonyms of Macabeo, Alarije, Dona Blanca, Chasselas, or Planta Nova, all included on the official Spanish list of commercial grape cultivars. Malvasia de Sitges and Malvasia de Lanzarote have the characteristic flavour of Malvasia grapes and no synonyms were found among the cultivars grown in Spain, whereas Malvasia Rosada resulted from a colour mutation in Malvasia de Sitges.

    Full Text Available Avaliou-se a resposta de nove cultivares de algodoeiro, de importância econômica no Estado do Mato Grosso, quanto à intoxicação causada por subdoses de glyphosate. Os cultivares de algodoeiro utilizados foram Fabrika, Makina, ITA-90, FM 986, FM 966, Delta Opal, BRS Facual, Antares e Coodetec 407. As plantas foram cultivadas em tubetes preenchidos com substrato de solo e mantidas em casa telada, tendo recebido a aplicação do glyphosate aos 20 dias após a emergência, época em que apresentavam quatro folhas verdadeiras. As subdoses de glyphosate, simulando deriva, foram de 270 e 540 g ha-1. Também foi utilizada testemunha, sem aplicação do herbicida, para efeito de comparação. Foram realizadas avaliações semanais até 42 dias após a aplicação dos tratamentos (DAA, período em que também foi tomada a altura das plantas. Os sintomas visuais de intoxicação iniciaram-se aos 3 DAA, caracterizados pelo amarelecimento das pontas das folhas mais novas, seguido de murchamento do ápice das plantas. Na dose de 270 g ha-1 esses sintomas foram de baixa intensidade, mas a 540 g ha-1 causaram, na maioria dos casos, toxidez "preocupante" a "muito alta". Os cultivares BRS Facual e FM 986 mostraram-se os mais suscetíveis. A altura das plantas foi mais afetada quando se aplicou a menor dose de glyphosate. Houve recuperação de todos os cultivares tratados com 270 g ha-1 de glyphosate até os 42 DAA. Quando tratados com 540 g ha-1 de glyphosate, os cultivares Fabrika, Coodetec 407, BRS-Facual e ITA-90 foram mais sensíveis, apresentando redução de altura entre 84 e 90% aos 42 DAA. Os cultivares menos sensíveis na dose de 270 g ha-1 de glyphosate não foram os mesmos para a dose de 540 g ha-1.The response of nine cotton cultivars economically important in the state of Mato Grosso was evaluated in relation to the toxicity caused by reduced rates of glyphosate.

    Full Text Available Cotton is one of the most important crops, both in the national context and worldwide. Being that, its fiber, constitutes an important raw material for the textile industry. The process of improving cottonseeds, favoured cultivars with smaller seeds. The goal of this work was to evaluate three cultivars of cottonseeds with different sizes through vigour tests. The work was developed in the seeds laboratory and the post-harvest Laboratory of plant products of the Instituto Federal Goiano – Campus Rio Verde. Cottonseeds of 3 cultivars were used (FiberMax 913 GLT, FiberMax 910 and DeltaPine 1648 B2RF, obtained in the crop of 2014 in the city of Primavera do Leste, Mato Grosso. The experimental design was entirely randomized, with eight replications of 50 seeds. Determinations of moisture content and weight of a hundred seeds, germination test and germination velocity index, emergency test, and emergency speed index, electrical conductivity and accelerated aging were conducted. The dimensions of the size of the seeds (length, width and thickness were also determined, with the aid of digital caliper, and the weight of the seeds, with the aid of a balance of precision of resolution 0, 001g. The data was subjected to analysis of variance and the averages compared to the Tukey test at 5% probability. There was no clear relationship between the size of the seed and its physiological performance in assessed cultivars/batches, making it necessary more studies that can prove that type of association.

    Natural variation occurs in the uptake and distribution of essential and nonessential trace elements among crop species and among cultivars within species. Such variation can be responsible for trace element deficiencies and toxicities, which in turn can affect the quality of food. Plant breeding can be an important tool to both increase the concentration of desirable trace elements and reduce that of potentially harmful trace elements such as cadmium (Cd). Selection programs for a low-Cd content of various crops, including durum wheat, sunflower, rice and soybean have been established and low-Cd durum wheat cultivars and sunflower hybrids have been developed. In durum wheat (Triticum turgidum L. var durum), low-Cd concentration is controlled by a single dominant gene. The trait is highly heritable, and incorporation of the low-Cd allele can help to reduce the average grain Cd to levels below proposed international limits. The allele for low-Cd concentration does not appear to affect major economic traits and should not cause problems when incorporated into durum cultivars. The cost of Cd selection in a breeding program is initially large both in terms of Cd determination and reduced progress towards development of other economic traits, but declines as more breeding lines in the program carry the low-Cd trait and are utilized in new crosses. Production of low-Cd crop cultivars can be used as a tool to reduce the risk of movement of Cd into the human diet.

    Six peanut (Arachis hypogaea L.) cultivars (Col-24-Gro, Col-61-Gto, VA-81-B, Ranferi Diaz, NC-2 and Florunner) were studied for agricultural yield, chemical composition (protein, fat, carbohydrates, fiber and ash), amino acid profile, digestibility, fatty acid profile, tocopherol and sterol contents. Results indicated that Ranferi Diaz and Col-61-Gto presented the highest yield (6.3 Ton/ha). Protein content was from 23.5 to 26.6% and fat content ranged from 49.8-53.4%. Mean digestibility was 86%. Lysine and threonine levels in all cultivars were sufficient to meet human requirements. Total saturated fatty acids ranged from 15-18%. The oleic/linoleic ratio was estimated 1.3-1.4. Tocopherol levels varied from 390 to 706 ppm. The highest tocopherol levels corresponded to the cultivars with the lowest yield. The alpha tocopherol content was estimated at 90-150 ppm, while gamma tocopherol was 270-570 ppm. The main sterol present was A- sitosterol (approx. 65%). Ranferi Diaz variety presented the highest agronomic yield and the highest protein content but low oleic acid, low sterols and low total tocopherols. The differences among cultivars suggest differences in their applications. (Author) 40 refs.

    Full Text Available Background. Blueberries are considered an important source of health benefits. This work studied six blueberry cultivars: “Duke,” “Brigitta”, “Elliott”, “Centurion”, “Star,” and “Jewel”, measuring quality parameters such as °Brix, pH, moisture content using standard techniques and shape, color, and fungal presence obtained by computer vision. The storage conditions were time (0–21 days, temperature (4 and 15°C, and relative humidity (75 and 90%. Results. Significant differences (P<0.05 were detected between fresh cultivars in pH, °Brix, shape, and color. However, the main parameters which changed depending on storage conditions, increasing at higher temperature, were color (from blue to red and fungal presence (from 0 to 15%, both detected using computer vision, which is important to determine a shelf life of 14 days for all cultivars. Similar behavior during storage was obtained for all cultivars. Conclusion. Computer vision proved to be a reliable and simple method to objectively determine blueberry decay during storage that can be used as an alternative approach to currently used subjective measurements.

    Full Text Available The lipid components and soluble sugars in flour samples of different cultivars of barley (Hordeum vulgare, involving winter malting barley, winter forage barley, spring barley, and hulless barley, were identified. Fatty acids were extracted from flour samples with n-hexane, and derivatized into volatile methyl esters, using TMSH (trimethylsulfonium hydroxide in methanol. Soluble sugars were extracted from defatted and dried samples of barley flour with 96% ethanol, and further derivatized into the corresponding trimethylsilyl (TMS oximes, using hydroxylamine hydrochloride solution and BSTFA (N,O-bis-(trimethylsilyl-trifluoroacetamide. The hexane and alcoholic extracts of barley cultivars were analyzed by GC-MS system. Lipid and sugar compositions were very similar in all barley cultivars. Therefore, multivariate analysis was applied to numerical values of automatically integrated areas of the identified fatty acid methyl esters and TMS oximes of soluble sugars. The application of hierarchical cluster analysis showed a great similarity between the investigated flour samples of barley cultivars, according to their fatty acid content (0.96. Also, significant, but somewhat less similarity was observed regarding the content of soluble sugars (0.70. These preliminary results indicate the possibility of distinguishing flour made of barley, regardless of the variety, from flours made of other cereal species, just by the analysis of the contents of fatty acids and soluble sugars.[Projekat Ministarstva nauke Republike Srbije, br.

    Full Text Available The toxins production by fungal pathogenic can enhance penetration and colonization of the host tissues and reproduce symptoms of diseases. Juglone is the main and the most toxic metabolite characterized from the culture filtrate of Mycosphaerella fijiensis. In the present work it was used different concentrations of juglone (10, 25, 50 and 100 mg.l-1 and a control solution of methanol 10%. Foliar injections were performed in the underside of two last open leaves of Grande naine (AAA and Fougamou (ABB cultivars. The percentage of necrosis per plant was evaluated at 24 hours after the injection. The concentration of 100 mg.l-1 was able to produce necrotic symptoms in both cultivars; nevertheless with the 50 mg.l-1 was possible to obtain differences between the two cultivars. This result established a concentration for screening two Musa spp cultivars with different resistance levels to Black Leaf Streak by the use of juglone.

    Full Text Available Studies of physiological parameters associated with crop performance and growth in different groups of upland rice (Oryza sativa L. may support plant breeding programs. We evaluated the role of gas exchange rates and dry matter accumulation (DMA as traits responsible for yields in a traditional (cv. ‘Caiapó’, intermediate (cv. ‘Primavera’ and modern (cv. ‘Maravilha’ upland rice cultivars. Leaf gas exchange rates, DMA, leaf area index (LAI, harvest indexes (HI and yield components were measured on these genotypes in the field, under sprinkler irrigation. Panicles per m2 and DMA at flowering (FL and heading, as well as CO2 assimilation rates (A were similar across these cultivars. The highest yield was found in ‘Primavera’, which may be explained by (i a two-fold higher HI compared to the other cultivars, (ii greater rates of DMA during spikelet formation and grain-filling, as well as (iii a slow natural decrease of A in this cultivar, at the end of the season (between FL and maturation.

    Full Text Available Although Brazil is the largest fig (Ficus carica L. producer in the Southern Hemisphere, it mainly uses only one cultivar, ‘Roxo de Valinhos’. In addition, propagation is almost entirely through hardwood cuttings. Therefore, the aim of this study was to establish a propagation method that provides more successful rooting of stem segments of fig cultivars for the purpose of expanding the genetic base of the fig tree. The cultivars used were ‘Brunswick’, ‘Calabacita’, ‘Negro de Bursa’, ‘Mini Figo’, ‘Lampa Preta’, ‘Lemon’, ‘Troiano’,’ Nazaré’, ‘Três num Prato’, ‘Princesa’, ‘Colo de Dama’, ‘Montes’, ‘Bêbera Branca’, ‘Pingo de Mel’, and ‘Roxo de Valinhos’. The propagation methods used were layering, hardwood cuttings, nodal segments, herbaceous cuttings originating from the removal of sprouts, and herbaceous cuttings obtained during growth. We found that the propagation method influences the rooting of stem segments, and cultivars differ in their rooting potential.

    2017-08-17

    Genotypes x environment (G x E) interaction consists of different behavior of genotypes cultivated in different environments. This interaction occurs due to the performance variation of each genotype in different environments. To reduce the effect of the interaction in soybean crops, some studies have been reported in the literature to study their adaptability and stability. However, these studies are still scarce in Minas Gerais State. Thus, the aim of this study was to verify the adaptability and stability of soybean cultivars and identify the cultivars that contribute least to the G x E interaction in Minas Gerais. Six soybean cultivars were evaluated in 9 different environments. The plots were composed of 4 rows of 5 m with a spacing of 0.5 m between rows, and only the two central rows were harvested. The inoculation with Bradyrhizobium japonicum was performed through sowing furrow. The fertilization followed the recommendations of the Soil Fertility Commission of Minas Gerais. Grain yield was evaluated in kg/ha after conversion to 13% moisture. After individual analysis, the joint analysis was performed by grouping the phenotypic means by the Scott and Knott (1974) test. Wricke's ecovalence methodologies and the Annicchiarico confidence index were applied for the adaptability and stability analysis. The interaction was decomposed into a simple and a complex part. The cultivars BRSMG 820RR and BRSMG 760SRR have wide adaptability and stability. The first one presents a better index of confidence and a small contribution to the interaction.
