    The hypotensive effects of the water extract of Marrubium vulgare L. and Foeniculum vulgare L. were investigated in spontaneously hypertensive rats (SHR) and in normotensive Wistar-Kyoto rats (WKY). Oral administration of Marrubium or Foeniculum extract lowered the systolic blood pressure of SHR but not of WKY. In SHR, Foeniculum but not Marrubium treatment increased water, sodium and potassium excretion. Ex vivo as well as in vitro, Marrubium extract inhibited the contractile responses of rat aorta to noradrenaline and to KCl (100 mM). Inhibition was greater in aorta from SHR compared to WKY and was not affected by the NO synthase inhibitor N-nitro-L-arginine. Vascular effects of Foeniculum extract were less pronounced than those of Marrubium and were blocked by N-nitro-L-arginine. These results indicate that hypotensive activity of Marrubium and Foeniculum extracts seems to be mediated through different pathways: Foeniculum appeared to act mainly as a diuretic and a natriuretic while Marrubium displayed vascular relaxant activity.

    Full Text Available Foeniculum vulgare is a widely distributed plant in most tropical and subtropical countries and have long been used in folk medicines to treat obstruction of the liver, spleen and gall bladder and for digestive complaints such as colic, indigestion, nausea and flatulence. In recent years the interest in this plant has increased considerably with substantial progress on its chemical and pharmacological properties. This review discusses the current knowledge of its chemistry, the various compounds isolated and pharamcological studies conducted. These studies carried out with the extracts and volatile oil support most of the reports of using this plant in folk medicines. However, well controlled, double-binding clinical trials are lacking. Several compounds including trans-anethole, estragole, fenchone and polyphenolics were isolated from this plant and some of these interact with potential mechanisms of the body. Together this data strongly supports the view that this plant has potential beneficial therapeutic actions in the management of bacterial and fungal infections, colic pain and lipid peroxidation.

    Full Text Available Methanolic extract of dried Fennel (Foeniculum vulgare Miller seeds was analyzed for the presence of bioreactive compounds: ascorbate, riboflavin, tocopherol and polyphenols with potential antioxidant properties. The extract had low ascorbate (197.12+1.82µg, riboflavin (11.97+0.35µg and tocopherol (280.33+5.67µg/g dry seeds content. However the extract had high polyphenol content (16.506+0.32mg/g dry seeds. Antioxidant activity of the extract was determined by various mechanisms including DPPH free radical scavenging, metal induced protein and lipid oxidation inhibition and protection of DNA against H2O2 induced damage. Fennel had excellent free radical scavenging activity with IC50 2.1mg dry seed weight. IC50 observed for protection of proteins and lipids against metal ion induced oxidation is 2.1 and 2.5mg dry seed weight respectively. Extract equivalent to 0.5µg seeds is enough to protect DNA against H2O2 induced oxidation. The results suggest that polyphenols are the principal components responsible for high antioxidant potential of methanolic extract of fennel.

    Full Text Available Aromatic plants are among the most important sources of biologically active secondary metabolites, with high antimicrobal potential. This study was carried out to examine in vitro antifungal activity of Foeniculum vulgare (Apiaceae, Carum carvi (Apiaceae and Eucalyptus sp.(Myrtaceae essential oils against three Candida albicans strains of different origin (laboratory-CAL, human pulmonary-CAH and ATCC10231-CAR. The essential oils were screened on C. albicans using disc and well-diffusion and microdilution method, and compared to Nystatine and Fluconazole as standard anti-mycotics. The activity of tested oils was expressed by inhibition zone diameter (mm, minimum inhibitory concentration (MIC and minimum fungicidal concentration (MFC (mg/ml. The results indicated that studied essential oils show antifungal activity against all three isolates of C. albicans. It was observed that each oil exhibits different degree of antifungal activity depending on the oil concentration applied as well as on analyzed strain of C. albicans. Carum carvi demonstrated the strongest antifungal effect to all tested strains, showing the lowest MIC values (0.03mg/ml for CAL, 0.06mg/ml for CAH, and 0.11mg/ml for CAR, respectively. Eucalyptus sp. exhibited the lowest antifungal activity, with MIC values ranging from 0.11 mg/ml for CAL to 0.45 mg/ml for both CAH and CAR. [Projekat Ministarstva nauke Republike Srbije, br. 172058

  8. Effect of gamma - irradiation on the volatile flavor profile of fennel (foeniculum vulgare mill.) from Pakistan

    International Nuclear Information System (INIS)

    The volatile flavor compounds of non-irradiated and 1, 5, 10 and 20 kGy gamma-irradiated seeds of fennel (Foeniculum vulgare Mill.) from Pakistan were isolated by simultaneous distillation-extraction (SDE) and were analyzed by gas chromatography-mass spectrometry (GC-MS). A total of 82 compounds were identified in the non irradiated fennel, with EAnethole (36.74 percentage), Estragole (26.31 percentage), and β-Limonene (15.99 percentage) as the major compounds. The irradiation doses caused slight variations in the number and contents of the volatile components. Though several volatile compounds showed increase after Υ-irradiation, the contents of major compounds such as beta-Limonene and estrgole were decreased. The overall number of the volatile compounds showed increase up to the recommended irradiation doses of 10 kGy but their contents decreased. In general no major change was noted in the overall major flavor compounds of the subject spice. Therefore the application of Υ--irradiation is feasible without any significant qualitative or quantitative loss of volatile flavor compounds when exposed to 10 kGy Υ--irradiation. (author)

  9. The Possible Protective Role of Foeniculum vulgare Mill. Against Radiation-Induced Certain Biochemical Changes in Albino Rats

    International Nuclear Information System (INIS)

    This study was conducted to evaluate the modulating efficacy of prolonged oral administration of Foeniculum vulgare Mill. essential oil (FEO) against gamma irradiation-induced biochemical changes in male rats. Essential oil of Foeniculum vulgare Mill. was orally administrated at dose level of 250 mg/kg body wt/day for 21 days before irradiation and 7 days post exposure (6.5 Gy single dose). Rats exposed to ionizing radiation exhibited a potential elevation of serum aspartate aminotransferase (AST) and alkaline phosphatase (ALP) activities, bilirubin, urea and creatinine levels, lipid abnormalities, and an increase in tissue lipid peroxidation (LPO) and metallothioneins (MTs). On the other hand, noticeable drop in liver and kidney glutathione content and serum total protein, albumin and testosterone levels were recorded. Tissue organs displayed some changes in trace element concentrations, which may be due to the radiation ability to induce oxidative stress. The data obtained from rats treated with fennel oil before and after whole body gamma irradiation revealed significant modulation in the biochemical tested parameters and profound improvement in the activity of antioxidant status, glutathione and metallothioneins. The treatment of irradiated rats with fennel oil also appeared to be effective in minimizing the radiation-induced increase in lipid peroxidation as well as changes in essential trace elements in some tissue organs. In addition to its containing many chemical antioxidant constituents such as polyphenols, fennel was found to contain detectable concentrations of essential trace elements (Zn, Cu, Fe, Se, Mg, Mn and Ca) which may be involved in multiple biological processes as constituents of enzymes system including superoxide dismutase (Cu, Zn, Mn, SODs), oxide reductase, glutathione (GSP, GSH, GST), metallothionein MTs, etc. Overall, it could be concluded that Foeniculum vulgare Mill. essential oil exerts beneficial protective role against radiation

    Full Text Available Abstract Background Anethum graveolens Linn., Foeniculum vulgare Mill. and Trachyspermum ammi L. are widely used traditional medicinal plants to treat various ailments. To provide a scientific basis to traditional uses of these plants, their aqueous and organic seed extracts, as well as isolated phytoconstituents were evaluated for their antibacterial potential. Methods Antibacterial activity of aqueous and organic seed extracts was assessed using agar diffusion assay, minimum inhibitory concentration and viable cell count studies; and their antibacterial effect was compared with some standard antibiotics. The presence of major phytoconstituents was detected qualitatively and quantitatively. The isolated phytoconstituents were subjected to disc diffusion assay to ascertain their antibacterial effect. Results Hot water and acetone seed extracts showed considerably good antibacterial activity against all the bacteria except Klebsiella pneumoniae and one strain of Pseudomonas aeruginosa. Minimum inhibitory concentration for aqueous and acetone seed extracts ranged from 20–80 mg/ml and 5–15 mg/ml respectively. Viable cell count studies revealed the bactericidal nature of the seed extracts. Statistical analysis proved the better/equal efficacy of some of these seed extracts as compared to standard antibiotics. Phytochemical analysis showed the presence of 2.80 – 4.23% alkaloids, 8.58 – 15.06% flavonoids, 19.71 – 27.77% tannins, 0.55–0.70% saponins and cardiac glycosides. Conclusion Antibacterial efficacy shown by these plants provides a scientific basis and thus, validates their traditional uses as homemade remedies. Isolation and purification of different phytochemicals may further yield significant antibacterial agents.

    International Nuclear Information System (INIS)

    Medicinal plants i.e. dried seeds of myristica argentea, myristica fragrans, coriandrum sativum and foeniculum vulgare were stored for 0 and 6 months, with and without gamma irradiation at 5 kGy. No detectable changes were seen in infrared and UV spectra, GLC chromatograms and refraction indeces of steam distilled, essential oils from the irradiated medicinal plants. The same results were also obtained from irradiated samples stored for 6 months at ambient conditions. Storage for 6 months caused significant changes in the gas liquid chromatograms and UV spectra of all samples compared to non-stored samples. The moisture content of all samples packed in polyethylene bags seems to be constant after 6 months of storage. No measurable changes were found in the amount of essential oil content caused by irradiation. (author)

    Dengue is a potentially fatal mosquito-borne infection with 50 million cases per year and 2.5 billion people vulnerable to the disease. This major public health problem has recurrent epidemics in Latin America and occurred recently in Cape Verde and Madeira Island. The lack of anti-viral treatment or vaccine makes the control of mosquito vectors a high option to prevent virus transmission. Essential oil (EO) constituents can affect insect's behaviour, being potentially effective in pest control. The present study evaluated the potential use of Foenicultm vulgare (fennel) EO in the control of the dengue vector Aedes aegypti. EOs isolated from fennel aerial parts collected in Cape Verde and from a commercial fennel EO of Portugal were analysed by NMR, GC and GC-MS. trans-Anethole (32 and 30%, respectively), limonene (28 and 18%, respectively) and fenchone (10% in both cases) were the main compounds identified in the EOs isolated from fennel from Cape Verde and Portugal, respectively. The larvicidal activity of the EOs and its major constituents were evaluated, using WHO procedures, against third instar larvae ofAe. aegypti for 24 h. Pure compounds, such as limonene isomers, were also assayed. The lethal concentrations LC50, C90 and LC99 were determined by probit analysis using mortality rates of bioassays. A 99% mortality of Ae. aegypti larvae was estimated at 37.1 and 52.4 µL L-1 of fennel EOs from Cape Verde and Portugal, respectively. Bioassays showed that fennel EOs from both countries displayed strong larvicidal effect against Ae. aegypti, the Cape Verde EO being as active as one of its major constituents, (-)-limonene.

    Full Text Available Com o objetivo de avaliar a produtividade e qualidade do funcho (Foeniculum vulgare Mill. produzido nas condições edafoclimáticas de Sergipe, foi conduzido cultivo orgânico de funcho em Frei Paulo-SE. Em junho de 2008 e de 2009, início do período de chuvas, foram instalados plantios por meio de mudas. Adicionalmente, em dezembro de 2010 foi realizada colheita de frutos a partir de plantas obtidas após poda drástica e rebrota. Foi realizada colheita de frutos e determinação da produtividade de dezembro a janeiro de 2008, 2009 e em dezembro de 2010. Verificou-se produtividade de 720 Kg.ha-1, no primeiro plantio e de 349 Kg.ha-1 no plantio de 2009. As plantas obtidas por rebrota em 2010 resultaram em produtividade de 589 Kg.ha-1. Sugere-se que a maior produtividade verificada no primeiro ano seja decorrente da maior precipitação média e conseqüente maior disponibilidade de água. A produtividade verificada nas plantas que rebrotaram em 2010 foi também superior a verificada em 2009, o que pode ser explicado tanto em função da maior precipitação, quanto em função do provável maior desenvolvimento das raízes e maior número de ramos após poda, devido à quebra da dominância apical. Esses dados sugerem importância da disponibilidade hídrica na determinação da produtividade na região e explicam a variação na produtividade verificada.

    Spodoptera frugiperda (Smith 1797) (Lepidoptera: Noctuidae) is a major pest of maize, Zea mays L. Its control is often achieved through repeated applications per season of insecticides, which may lead to adverse effects on the ecosystem. Thus, the study of alternative methods with less environmental impact has expanded to include the use of essential oils. These oils are products of the secondary metabolism in plants, and their insecticidal activity has been widely demonstrated in populations of many pest insects. This study evaluated the insecticidal activities of essential oils from Eucalyptus staigeriana, Ocimum gratissimum, and Foeniculum vulgare on Spodoptera frugiperda. Gas chromatography–mass spectrometry profiles and contact toxicity of these oils as well as their sublethal effects on larvae and reproductive parameters in adults were evaluated. All three oils had sublethal effects on S. frugiperda; however, the oil of O. gratissimum showed the best results at all doses tested. These essential oils may have promise for control of S. frugiperda. PMID:26868417

  5. Irradiated Sewage Sludge for Production of Fennel (Foeniculum vulgare L.) Plants in Sandy Soil 2- Seed production, oil content, oil constituents and heavy metals in seeds

    International Nuclear Information System (INIS)

    Field experiment was conducted to study the impact of irradiated and non-irradiated sewage sludge applied to sandy soil on fennel plants (Foeniculum vulgare L.) productivity. In this regards, four rates of sewage sludge application were used (20, 40, 60 and 80 ton/ha) in addition to the mineral fertilizer treatment (control). Sandy soil amended with sewage sludge showed a promising effect on fennel seed yield. A linear gradual increase in seeds yield was observed as the sludge application rate increases. Seeds production increased by 41% to 308% over the control at 80t/ha application rate, for non-irradiated and irradiated sewage sludge treatments, respectively. Irradiated sewage sludge treatments showed higher fennel seed yield than non-irradiated sewage sludge treatments.Volatile oil percent exhibited no observable variation due to the use of sewage sludge. A few and limited fluctuations could be observed. However, total oil content (cc/plot) increased due to the increase in seeds yield. The magnitude of increase in volatile oil production in response to the sewage sludge application was parallel to the increase in seeds yield. The GLC measurements of the fennel volatile oil reveal that, the t-anethole is the predominant fraction. However, fenchone was detected in relatively moderate concentration. The applied sewage sludge treatment induced some variations in fennel volatile oil constituents. The t.anethole is relatively higher in volatile oil obtained from plants grown on sandy soil fertilized with non-irradiated sewage sludge than the one fertilized with irradiated sewage sludge or chemical fertilizer. In the meantime, the obtained increase in t.anethole was accompanied by a decline in fenchone content. Seeds heavy metals (Zn, Fe, Pb, Cd) were determined. Under all sludge application rates iron and zinc concentrations were in the normal plant concentration range whereas, Cd concentrations were traces.

    Pimpinella anisum (anise), belonging to Umbelliferae family, is an aromatic plant which has been used In Iranian traditional medicine (especially its fruits) as carminative, aromatic, disinfectant, and galactagogue. Because the wide traditional usage of Pimpinella anisum for treatment of diseases, in this review published scientific reports about the composition and pharmacological properties of this plant were collected with electronic literature search of GoogleScholar, PubMed, Sciencedirect, Scopus, and SID from 1970 to 2011. So far, different studies were performed on aniseeds and various properties such as antimicrobial, antifungal, antiviral, antioxidant, muscle relaxant, analgesic and anticonvulsant activity as well as different effects on gastrointestinal system have been reported of aniseeds. It can also reduce morphine dependence and has beneficial effects on dysmenorrhea and menopausal hot flashes in women. In diabetic patients, aniseeds showed hypoglycemic and hypolipidemic effect and reduce lipid peroxidation. The most important compounds of aniseeds essential oil were trans-anetole, estragole, γ-hymachalen, para-anisaldehyde and methyl cavicol. Due to broad spectrum of pharmacological effects, and very few clinical studies of Pimpinella anisum, more clinical trials are recommended to evaluate the beneficial effects of this plant in human models and synthesis of new drugs from the active ingredients of this plant in future.

  9. Effect of gamma irradiation on microbiological, chemical and sensory characteristics of aniseed (anisum vulgare)

    International Nuclear Information System (INIS)

    Seeds of ansium were exposed to doses of 0, 5, 10, 15 and 20 kGy in a 60Co package irradiator, Irradiated and unirradiated samples were stored at room temperature. Microbial population on seeds, dissolved organic and inorganic solids in extract and sensory properties of extract were evaluated after 0, 6 and 12 months of storage. The results indicated that gamma irradiation reduced the aerobic plate counts. Immediately after irradiation, the dissolved organic solids in extract of irradiated seeds were higher than those of non-irradiated ones. The dissolved organic matter in extract of irradiated and un-irradiated ansium seeds increased. After 6 and 12 months of storage. There were no significant differences in dissolved solids between the extract of irradiated and non-irradiated ansium seeds. Sensory evaluation indicated that gamma irradiation improved sensory characteristics of ansium seed extract tested immediately after irradiation; however, after 12 months of storage, no significant differences (P>0.05) were found in color, taste or odor between extract of irradiated and unirradiated ansium seeds.

    In order to evaluate the effects of different organic and biological fertilizers on quantity and quality of fennel essential oil, an experiment was conducted in a completely randomized block design with three replications. The experimental treatments included two organic (compost and vermicompost) and two biological (Pseudomonas putida and Azotobacter chroococcum) fertilizers, their all twin combinations (Ps. putida + A. chroococcum, Ps. putida + compost, Ps. putida + vermicompost, A. chroococcum + compost, A. chroococcum + vermicompost and compost + vermicompost) and control (non fertilized). There were significant differences between treatments in terms of seed essential oil percentage, essential oil yield; anethole, fenchone, limonene and straggle content in seed essential oil. Results showed that the highest and the lowest percentages of essential oil were obtained in control (2.9%) and A. chroococcum + vermicompost (2.2%) treatments, respectively. The highest essential oil yield (29.9 L ha{sup -}1) and anethole content of essential oil (69.7%) and the lowest contents of fenchone (6.14%), limonene (4.84%) and estragole (2.78%) in essential oil were obtained in compost + vermicompost treatment. It seems that compost + vermicompost treatment compared to other treatments supplied the highest equilibrium of nutrients and water in the root zone of sweet fennel which is led to increasing the anethole content, there upon, decreasing other compounds. Essential oil yield and percentage of anethole content in essential oil were significantly higher in all organic and biological treatments compared with control. (Author) 43 refs.

The lowest fresh and dry weights of plants occurred with the 50% NPK. Also, addition of biofertilizer with the chemical fertilizer increased these characters more than the half dose of chemical fertilizer alone. Total carbohydrates in the dry plant material were influenced by the biofertilizer. The highest values of total carbohydrates were found in the treatment with biofertilizer plus a half dose of nitrogen and phosphorus. Nitrogen, phosphorus, and potassium levels in the plant tissue increased when soil was inoculated by nitrogen-fixing bacteria, phosphate-dissolving bacteria, and a mixture of all strains, respectively. The least amount of N, P and K in the plant tissue occurred with the half dose of chemical fertilizer. Essential oil content in the fennel fruits was increased due to inoculation compared to the half dose of chemical fertilizer. The highest oil yield per plant was observed with the treatment of biofertilizer plus a half dose of nitrogen and phosphorus. The lowest amount of essential oil yield was obtained with the half dose of chemical fertilizer. Oxygenated compounds were increased as a result of using biofertilizer. The highest anethol (trans-1-methoxy-4-(prop-1-enylbenzeen; C10H12O in fennel essential oil occurred with the half dose of N, P, and K and inoculation with Bacillus megatherium.

    In this study, antioxidant, antibacterial and antiglycation properties of methanolic extracts of 23 fennel samples were evaluated and their major compounds were determined using HPLC analysis. The anti-glycative activity of extracts was evaluated in the bovine serum albumin (BSA)/glucose system. The level of glycation, conformational alterations and protein binding to RAGE receptors were assessed by Congo red binding assay and a brown staining method. Among samples, Kh1 from Iran possessed the highest TFC (14.8mgQUEg(-1)), TPC (262mg/g DW) and antioxidant activity (IC50=76μg/ml). The HPLC results revealed high variation in 23 fennel samples according to their major flavonoid (quercetin, apigenin and rutin) and phenolic (chlorogenic, caffeic and 1,5-dicaffeoylquinic acid) compounds. The antibacterial activity of methanolic extracts against four food-borne pathogens was also assessed. The seed extracts of Kh1 and En samples showed moderate to good inhibitory activities (MICs=62.5-125μg/ml) against three bacteria, as well as high anti-glycative activity. PMID:27451172

  18. Gamma Radiation Impact on the Survival Microflora and Biochemical Constituents of Stored Anise Seeds (Pimpenella anisum L.)

    International Nuclear Information System (INIS)

    Anise seeds (Pimpenella anisum L.) were exposed to gamma irradiation doses (0, 4, 8, 16 and 32 KGy). Irradiated and un-irradiated anise seeds were stored for 3, 6 and 12 months and tested for their microbial population . In addition, the chemical constituents (volatile oils, fatty acids, lipids and sugars) were evaluated. The predominant microorganisms contaminated anise seeds include different fungal species identified as Aspergillus niger, A. ochraceus, A. parasiticus, A. flavus, A. fumigatus , Penicillium funiculosum , P. italicum , Rhizopus sp. and Trichoderma viride. Different bacterial species as Bacillus circulans, B. subtilis, B. megaterium, B. brevis, Pseudomonas fluorescens, P. oleourans and Alicyclobacillus acidocaldarius were recorded. The imposed irradiation doses showed a promising effect to decontaminate the microbial load , which in turn showed prolong the storage periods. Volatile oil content was relatively declined during storage. In addition, some alternations were happened regarding the essential oils constituents. However, the applied irradiation doses maintained the volatile oil content and retained its constituents near to the normal control. Total lipids content were not influenced by either the applied storage periods or the used gamma irradiation doses. However, the fatty acids methyl ester showed some changes due to the imposed treatments. Sugars content were increased in the stored and un-irradiated seeds, however, the exposure to gamma radiation reduced this increase and retained sugars content near to the normal level of the control seeds.

    Full Text Available The epigraphic material from the region of Naissus, in spite of its relative scarcity and poor state of preservation, offers valuable examples of Vulgar Latin usage. Interesting phenomena include an instance of the imperial name Pertinax in the form Pertenax, which may be due to a vulgar reinterpretation of the name (‘Very Tough’, cf. Constans, Valens, sim. and may imply rhizotony (Perténax; the adjective superstantes ‘survivors’, apparently the issue of two consequent vulgar developments, superstes > superstens (hypercorrect spelling > superstans (false analogy; an isosyllabic 3rd declension nominative singular, Melioris (from the name Melior, as well as a 3rd decl. dative singular generi from the 2nd decl. noun gener ‘son-in-law’; an early borrowing from Germanic, brutes ‘daughter-in-law’; a ‘weak’ future participle, sequiture, for secuturae; the bastard noun volumptas, cf. voluntas and voluptas; a correlative construction with sic...sic for quemadmodum...sic; and the verb adjuvare followed by a dative, which illustrates a vulgarism known from the Glossaries. Another kind of vulgarity, which is rather a matter of simplicity than purely linguistic incompetence, is found in cases such as an epitaph whose dedicator calls herself bene merita; or a semi-metric inscription-a commaticum-whose actual text may be the outcome of tampering with a regular epigraphic poem

    The isolation and identification of major phenylpropanoid esters from Marrubium vulgare: (+) (E)-caffeoyl-L-malic acid 1, acteoside 2, forsythoside B 3, arenarioside 4, ballotetroside 5, as well as their anti-inflammatory activity are reported for the first time. We evaluated the inhibitory effects of these five compounds on cyclooxygenase (Cox) catalysed prostaglandin biosynthesis activity. Only the glycosidic phenylpropanoid esters showed an inhibitory activity towards the Cox-2 enzyme and three of them: acteoside 2, forsythoside B 3, arenarioside 4, exhibited higher inhibitory potencies on Cox-2 than on Cox-1. These results are of interest, as Cox-2 is mainly associated with inflammation and the Cox-1 inhibition with adverse side effects often observed with non-steroidal anti-inflammatory drugs. The occurrence of these phenylpropanoid esters could also explain some other pharmacological properties of M. vulgare. PMID:11849848

    Purpose: In the present study we aimed to quantify marrubiin, as the major active compound, in the aerial parts of Marrubium vulgare from Iran using a HPTLC-densitometry technique. Methods: Quantitative determination of marrubiin in M. vulgare methanol extract was performed by HPTLC analysis via a fully automated TLC scanner. Later on, the in vitro antioxidant activity of the M. vulgare methanol extract was determined using 1,1-diphenyl-2-picryl-hydrazil (DPPH) free radical scavenging assay. Furthermore, total phenolics and flavonoids contents of the methanol extract were quantified, spectrophotometrically. Results: The amount of marrubiin was calculated as 156 mg/g of M. vulgare extract. The antioxidant assay revealed a strong radical scavenging activity for the M. vulgare methanol extract with RC50 value of 8.24μg/mL. Total phenolics and flavonoids contents for M. vulgare were determined as 60.4 mg gallic acid equivalent and 12.05 mg quercetin equivalent per each gram of the extract, correspondingly. Conclusion: The presented fingerprint of marrubiin in M. vulgare extract developed by HPTLC densitometry afforded a detailed chemical profile, which might be useful in the identification as well as quality evaluation of herbal medications based on M. vulgare. Besides, the considerable antioxidant activity of M. vulgare was associated with the presence of marrubiin along with phenolics and flavonoids exerting a synergistic effect. PMID:27123428

    Marrubium vulgare L. is a medicinal plant used in folk medicine to cure a variety of diseases. Recently we have demonstrated that a hydroalcoholic extract of this plant showed significant, nonspecific antispasmodic effects on isolated smooth muscle. In this report, we have investigated the possible analgesic effects of the same hydroalcoholic extract in different models of pain in mice. The results suggest that this extract exhibits significant analgesic activity, antagonizing chemically-induced acute pain. Such effects may be related to the presence of steroids and terpenes, which were detected by TLC analysis. PMID:23195761

    Full Text Available The uncontrolled use of synthetic insecticides is a great hazard for the environment and consumers. Essential oils were introduced as low toxic agents against mammals and non-targeted insects. In this study, essential oil from aerial parts of blue giant hyssop (Agastache foeniculum [Pursh] Kuntze (Lamiaceae was isolated by the water steam distillation method with a Clevenger apparatus, and its chemical composition was studied by gas chromatography mass spectrometry. The toxicity of A. foeniculum essential oil against red flour beetle, Tribolium castaneum (Herbst, and lesser grain borer Rhyzopertha dominica (F. was evaluated by fumigation at 24, 48, and 72 h exposure times. Estragole and 1,8-cineole were identified as major constituents of the A. foeniculum oil. Fumigation bioassays revealed that A.foeniculum oil had strong insecticidal activity on experimental insects. Rhyzopertha dominica was more susceptible than T. castaneum for all exposure times. Insecticidal activity varied with essential oil concentration and exposure time. Probit analysis showed that increased exposure time and essential oil concentration increased mortality. These results indicated that A. foeniculum essential oil can be applied in the management of stored-product insects to decrease the detrimental effects of synthetic insecticides.El uso incontrolado de los insecticidas sintéticos causa gran peligro para el medio ambiente y los consumidores.

    Full Text Available Abstract Background Origanum vulgare Linn has traditionally been used in the treatment of urolithiasis. Therefore, we investigated the crude extract of Origanum vulgare for possible antiurolithic effect, to rationalize its medicinal use. Methods The crude aqueous-methanolic extract of Origanum vulgare (Ov.Cr was studied using the in vitro and in vivo methods. In the in vitro experiments, supersaturated solution of calcium and oxalate, kidney epithelial cell lines (MDCK and urinary bladder of rabbits were used, whereas, in the in vivo studies, rat model of urolithiasis was used for the study of preventive and curative effect. Results In the in vitro experiments, Ov.Cr exhibited a concentration-dependent (0.25-4 mg/ml inhibitory effect on the slope of nucleation and aggregation and also decreased the number of calcium oxalate monohydrate crystals (COM produced in calcium oxalate metastable solutions. It also showed concentration-dependent antioxidant effect against DPPH free radical and lipid peroxidation induced in rat kidney tissue homogenate. Ov.Cr reduced the cell toxicity using MTT assay and LDH release in renal epithelial cells (MDCK exposed to oxalate (0.5 mM and COM (66 μg/cm2 crystals. Ov.Cr relaxed high K+ (80 mM induced contraction in rabbit urinary bladder strips, and shifted the calcium concentration-response curves (CRCs towards right with suppression of the maximum response similar to that of verapamil, a standard calcium channel blocker. In male Wistar rats receiving lithogenic treatment comprising of 0.75% ethylene glycol in drinking water given for 3 weeks along with ammonium chloride (NH4Cl for the first 5 days, Ov.Cr treatment (10-30 mg/kg prevented as well as reversed toxic changes including loss of body weight, polyurea, crystalluria, oxaluria, raised serum urea and creatinine levels and crystal deposition in kidneys compared to their respective controls.

    Full Text Available The fine structure of plastids was studied in the course of androgenesis in in the pollen of Hordeum vulgare L. It was found that these organelles occur in all stages of androgenesis. Their structure was simple and was frequently manifested on the cross section only by the presence of the envelope and matrix of different degree of density. Single thylakoids, nucleoid-like regions and starch grains were, however, also noted. The structure of plastids in embryoids formed from microspores of barley was compared with embryos developed from fertilized egg cell, and we did not found any fundamental differences between them. However, only plastid ribosomes were difficult to identify on ultrathin sections in embryoids and in the embryos.

    Full Text Available In this article we study the translations of Carlos Jansen for the youth, age group corresponding approximately to the contemporary concepts of preadolescence and adolescence, made at the end of the 19th century. Jansen was a pioneer in translating into Brazilian Portuguese works for the youth among which novels by Swift, Defoe, and Cervantes. His widely adapted versions had a pedagogical goal, serving as a reading material for children and adolescents attending schools. For this reason he was called a "vulgarizer" by critics of that period. The research encompassed the analysis of newspapers published between 1880 and 1899, available at the National Library's Hemeroteca Digital Brasileira, which provide data on the advertising and reception of his works. We intend to enrich historical research on children's literature in Brazil and analyse to what degree Jansen's pedagogical project has governed his translation practice.

    Qian Ma

    Full Text Available Ketogulonicigenium vulgare, though grows poorly when mono-cultured, has been widely used in the industrial production of the precursor of vitamin C with the coculture of Bacillus megaterium. Various efforts have been made to clarify the synergic pattern of this artificial microbial community and to improve the growth and production ability of K. vulgare, but there is still no sound explanation. In previous research, we found that the addition of reduced glutathione into K. vulgare monoculture could significantly improve its growth and productivity. By performing SEM and TEM, we observed that after adding GSH into K. vulgare monoculture, cells became about 4-6 folds elongated, and formed intracytoplasmic membranes (ICM. To explore the molecular mechanism and provide insights into the investigation of the synergic pattern of the co-culture system, we conducted a comparative iTRAQ-2-D-LC-MS/MS-based proteomic analysis of K. vulgare grown under reduced glutathione. Principal component analysis of proteomic data showed that after the addition of glutathione, proteins for thiamin/thiamin pyrophosphate (TPP transport, glutathione transport and the maintenance of membrane integrity, together with several membrane-bound dehydrogenases had significant up-regulation. Besides, several proteins participating in the pentose phosphate pathway and tricarboxylic acid cycle were also up-regulated. Additionally, proteins combating intracellular reactive oxygen species were also up-regulated, which similarly occurred in K. vulgare when the co-cultured B. megaterium cells lysed from our former research results. This study reveals the demand for transmembrane transport of substrates, especially thiamin, and the demand for antioxidant protection of K. vulgare.

    This paper describes the antioedematogenic profile of marrubiin (1), the main constituent of Marrubium vulgare, a medicinal plant used in folk medicine of several countries to treat different pathologies. Compound (1) was analyzed in a model of microvascular leakage in mice ears. The results show that it exhibits significant and dose-related antioedematogenic effects. The results obtained for ID50 values (mg/kg, i.p.) and maximal inhibition (%) for the different phlogistic agents used were as follows: histamine (HIS, 13.84 mg/kg and 73.7%); (BK, 18.82 mg/kg and 70.0%); carrageenan (CAR, 13.61 mg/kg and 63.0%). The other phlogistic agonists, such as prostaglandin E2 (PGE2), caused inhibition of less than 50%. In addition, (1) (100 mg/kg) significantly inhibited the OVO-induced allergic edema in actively sensitized animals (maximal inhibition 67.6+/-4%). Our results demonstrate that the systemic administration of marrubiin exerts a non-specific inhibitory effect on pro-inflammatory agent-induced microvascular extravasation of Evans blue in mouse ear.

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 aim of the present work was to determine the in vitro effect of T. vulgaris and O. vulgare essential oils against E. granulosus protoscoleces and cysts. Essential oils were added to the medium resulting in thymol final concentrations of 10 μg/mL. The essential oils had a time-dependent effect provoking the complete loss of protoscolex viability after 72 days of postincubation. The results were confirmed at the ultrastructure level. Loss of infectivity in protoscoleces incubated with O. vulgare after 60 days was observed. On the other hand, the weight of cysts recorded in mice inoculated with T. vulgaris treated protoscoleces was significantly lower than that obtained in control group. Gamma-glutamyl-transpeptidase activity was readily detected in the culture supernatant of protoscoleces treated either with the essential oils or thymol. T. vulgaris and O. vulgare essential oils and thymol can induce cell apoptosis of protoscoleces after short incubation times. The efficacy of T. vulgaris and O. vulgare essential oils was also demonstrated in vitro on E. granulosus murine cysts. Our data suggest that essential oils of T. vulgaris and O. vulgare have anthelmintic effect against protoscoleces and cysts of E. granulosus.

    The hepatoprotective activity of Marrubium vulgare against cyclophosphamide toxicity in Wistar rats was evaluated. Adult male rats were divided into 4 groups of 6 each: a control group, a group injected with cyclophosphamide (150 mg·kg(-1)) for 3 days, a group orally given a M. vulgare aqueous extract ((500 mg of dry leaves)·kg(-1)·day(-1)) for 30 days then treated with cyclophosphamide, and a group receiving only M. vulgare for 30 days. After 33 days of treatment, activities of alanine amino transferase (ALAT), aspartate amino transferase (ASAT), lactate dehydrogenase (LDH), and alkaline phosphatase (ALP) were determined in serum. Moreover, lipid peroxidation level and superoxide dismutase (SOD) activities, catalase (CAT) and glutathione peroxidase (GPx) were measured in liver. Alterations of these hepatic biomarkers and increased lipid peroxidation confirmed cyclophosphamide-induced liver toxicity. Cyclophosphamide also decreased the enzymatic defense system against oxidative stress. However, when this drug was administered in rats given M. vulgare extract, all the biological parameters underwent much less alteration. Administration of M. vulgare extract was found to be beneficial by attenuating cyclophosphamide-induced liver damage. The protective effect of the plant is mainly attributed to its antioxidant properties and the existence of phenolic acids and flavonoids, as highlighted by HPLC-based analysis. PMID:26886858

    Four B-hordein genes, designated BH1-BH4, were cloned using PCR amplification from two hull-less barley cultivars, ZQ7239 and ZQ148, collected from Tibet. The results of sequencing indicated that BH1-BH4 contained complete open reading frames (ORFs). Comparison of their predicted polypeptide sequences with the published sequences suggested that they all share the same basic protein structure. Phylogenetic analysis indicated that the deduced amino-acid sequences of BH1-BH4 genes were more closely related to B-hordeins from cultivated barley (Hordeum vulgare L.) than to any other prolamins from wild barley and Aegilops tauschii. Comparison of the coding regions of BH1-BH4 genes showed that BH1 had a lower sequence identity to other previously published B-hordeins than the other three B-hordeins obtained in this study. BH1 was then cloned in a bacterial expression vector based on bacteriophage T7 RNA polymerase. The resulting plasmid produced a 28.15 kDa protein in Escherichia coli. The potential value of B-hordein genes in grain quality improvement of hull-less barley has been discussed. PMID:17046594

    The recommended conservative treatment of hyperoxaluria is mainly based on hyperhydration and ingestion of inhibitors of crystallization. In accordance with this context, the aim of this study was to determine the in vitro effect of Hordeum vulgare on calcium oxalate crystallization oxalo-dependent. The crystallization of calcium oxalate monohydrate in supersaturated aqueous solution at 37 °C, was followed in a model turbidimetric continuous in a closed system. The proposed model is very good reproducibility (CV < 10%), crystallization was monitored continuously in the presence of Hordeum vulgare at different concentrations (0.0625 to 1 g/L). The comparison of turbidimetric parameters, that characterize the growth stage of monohydrated oxalate calcium crystals and observation of the crystals obtained at the end of crystallization into scanning electron microscopy, have been able to demonstrate the inducing effect of Hordeum vulgare to 0.0625 g/L and a slight inhibitory effect at the others concentrations.

    Full Text Available This paper investigates the antimicrobial action of the extracts and essential oil of wildgrowing Tanacetum vulgare L on: Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Bacilus subtilis, using the diffusion disc method. The essential oils but also the ethanolic extracts tested exhibited moderate action on Staphilococcus aureus and Bacillus subtilis and low action on E. coli and Pseudomonas aeruginosa. The moderate antimicrobial activity is related to the amount of some chemical components of the essential oil of T. vulgare flos. Thus, this paper presents also the quantitative and qualitative analysis of the essential oils of T. vulgare harvested from two different habitats. The essential oils obtained by steam-distillation were analysed by gas-cromatography coupled with mass spectrometry (GC-MS.

    Full Text Available The micromorphology of selected elements of Echium vulgare L. flowers was investigated, with special attention to the structure of the nectaries and the stigma of the pistil as well as types of trichomes occurring on the surface of the calyx. The nectary had the shape of an uneven disc located around the lower region of the four-parted ovary of the pistil. The glandular cells formed a tier with a height of 330 μm and a radial width of 144 μm. Nectar was secreted onto the nectary surface through anomocytic stomata located at the level of other epidermal cells. Most of the stomata were open, with a different dimension of the pore. Their largest number was observed at the base of the nectary, and 462 stomata were noted on the whole surface of the nectary. The cuticle on the surface of the guard cells formed fine, circular striae. The subsidiary cells formed striated cuticular ornamentation, with the striae arranged radially in the direction of the stoma, whereas on the surface of other epidermal cells the striae formed an arrangement with different directions. The epidermis on the surface of the stigma formed regularly arranged papillae with a fan-shaped, expanded upper part which had corrugated outer walls, whereas the base of the cell formed a widened small column. The epidermis of the abaxial part of the calyx was covered by numerous non-glandular trichomes of different length which were made up of one or several cells. The glandular trichomes in the epidermis of the calyx grew with smaller density compared to the protective trichomes, and they were composed of a 1-2-celled stalk and a glandular head.

    Full Text Available Origanum vulgare L., Lamiaceae, from six different production areas of China and Pakistan were analyzed via gas chromatography equipped with a flame ionization detector (GC-FID and examined for their volatile constituents by gas chromatography-mass spectroscopy (GCMS. This procedure allowed the identification of 11 to 46 components among six production areas, representing 98.5% to 99.9% of the total oil extracted. The yields of the essential oil of the six production areas of O. vulgare ranged from 0.1 to 0.7%. The class of oxygenated monoterpenes was predominant in all the essential oils. However, samples S5 and S6 have high content of sesquiterpene hydrocarbons (33.7 and 43.7%; while sample S6 is high on oxygenated sesquiterpene (32.9%. The principal component analysis of O. vulgare was employed to provide a comprehensive evaluation of essential oil components. The cluster analysis of O. vulgare was classified into three subsets, characterized according to the major essential oil components. The current study investigated the composition differences of essential oil among six production areas offering foundation for quality control, resource optimization, and clinical treatments.

    Full Text Available Pimpinella anisum, is a plant species popularly used as treatment for different diseases, although no studies exist which could prove its pharmacological activity. This species has no known methods of asepsis and adequate conditions to conduct in vitro propagation trials. To assess the most efficient method of seed sterilization and the most favorable concentration of agar and MS salts, five tests of asepsis and tests to evaluate the dry mass increase of germinated seed in 3g/L and 6g/L of agar and MS in concentrations of 0%, 25%, 50%, 75% and 100%, were carried out. The samples that were immersed in a concentration of 2% sodium hypochlorite for 20 minutes and then washed in distilled water produced 100% of sterile plantlets. The greatest increase in dry mass was obtained with 75% and 100% of MS salts. Furthermore, the different concentrations of agar did not influence the percentage of the plantlets dry mass. Pimpinella anisum é uma planta popularmente utilizada como medicinal para diversas enfermidades, embora não existam estudos que comprovem sua atividade farmacológica.

    Barley (Hordeum vulgare) is an economically important species, which can be cultivated in environmentally adverse conditions due to its higher tolerance in contrast to other cereal crops. The draft of H. vulgare genome is available already for couple of years; however its functional annotation is still incomplete. All available databases were searched to expand current annotation. The improved annotation was used to describe processes and genes regulated in transgenic lines showing higher tolerance to drought in our associated article, doi:10.1016/j.nbt.2016.01.010 (Vojta et al., 2016) [1]. Here we present whole transcriptome response, using extended annotation, to severe drought stress and subsequent re-watering in wild-type barley plants in stem elongation phase of growth. Up- and down-regulated genes fall into distinct GO categories and these enriched by stress and revitalization are highlighted. Transcriptomic data were evaluated separately for root and aerial tissues. PMID:27331111

    Informed collecting, conservation, monitoring and utilization of genetic diversity requires knowledge of the distribution and structure of the variation occurring in a species. Hordeum vulgare subsp. spontaneum (K. Koch) Thell., a primary wild relative of barley, is an important source of genetic diversity for barley improvement and co-occurs with the domesticate within the center of origin. We studied the current distribution of genetic diversity and population structure in H. vulgare subsp. spontaneum in Jordan and investigated whether it is correlated with either spatial or climatic variation inferred from publically available climate layers commonly used in conservation and ecogeographical studies. The genetic structure of 32 populations collected in 2012 was analyzed with 37 SSRs. Three distinct genetic clusters were identified. Populations were characterized by admixture and high allelic richness, and genetic diversity was concentrated in the northern part of the study area. Genetic structure, spatial location and climate were not correlated. This may point out a limitation in using large scale climatic data layers to predict genetic diversity, especially as it is applied to regional genetic resources collections in H. vulgare subsp. spontaneum.

  15. Biosynthesis of the labdane diterpene marrubiin in Marrubium vulgare via a non-mevalonate pathway.

    Knöss, W; Reuter, B; Zapp, J

    1997-09-01

    The biosynthesis of the furanic labdane diterpene marrubiin has been studied in plantlets and shoot cultures of Marrubium vulgare (Lamiaceae). The use of [2-14C]acetate, [2-14C]pyruvate, [2-14C]mevalonic acid and [U-14C]glucose incorporation experiments showed that the labelling of sterols in etiolated shoot cultures of M. vulgare was in accordance with their biosynthesis via the acetate-mevalonate pathway. In contrast, the incorporation rates of these precursors into the diterpene marrubiin could not be explained by biosynthesis of this compound via the acetate-mevalonate pathway. Cultivation of etiolated shoot cultures of M. vulgare on medium containing [1-13C]glucose and subsequent 13C-NMR spectroscopy of marrubiin led to the conclusion that the biosynthesis of marrubiin follows a non-mevalonate pathway. All isoprenic units of 13C-labelled marrubiin were enriched in those carbons that correspond to positions 1 and 5 of a putative precursor isopentenyl diphosphate. This labelling pattern from [1-13C]glucose is consistent with an alternative pathway via trioses, which has already been shown to occur in Eubacteria and Gymnospermae. The labdane skeleton is a precursor of many other skeletal types of diterpenes. Therefore it becomes obvious that in connection with the few known examples of a non-mevalonate pathway to isoprenoids the formation of some isoprenoids in plants via a non-mevalonate pathway might be quite common.

  16. Using elevated CO2 to increase the biomass of a Sorghum vulgare x Sorghum vulgare var. sudanense hybrid and Trifolium pratense L. and to trigger hyperaccumulation of cesium

    International Nuclear Information System (INIS)

    The most important challenge to use phytoremediation is how to improve its efficiency by increasing the accumulation of metals in plants, or by improving key plant biological traits that should enhance metal uptake. In this paper, we used open-top chambers to investigate the effects of elevated CO2 (860 μL L-1) on biomass and Cs uptake by a Sorghum vulgare x Sorghum vulgare var. sudanense hybrid and Trifolium pratense L. growing on soils spiked with various levels of cesium (0, 300, 1500 and 3000 mg Cs kg-1). The results showed that elevated CO2 not only increased aboveground biomass of the Sorghum and Trifolium species by 32-111%, and by 8-11%, respectively, compared to the ambient CO2 treatment, but also caused more accumulation of Cs by Sorghum species (up to 73%) than Trifolium species (up to 43%). It was speculated that the increase in biomass and the improvement in Cs accumulation ability at elevated CO2 could be related to lowered soil pH values, and changes in number and kind of microorganisms in the rhizospheres of the two tested species. This is the first report of a link among elevated CO2, increased biomass and hyperaccumulation of Cs by Sorghum and Trifolium species.

    Antilisterial activities of Thymbra capitata and Origanum vulgare essential oils were tested against 41 strains of Listeria monocytogenes. The oil of T. capitata was mainly constituted by one component, carvacrol (79%), whereas for O. vulgare three components constituted 70% of the oil, namely, thymol (33%), gamma-terpinene (26%), and p-cymene (11%). T. capitata essential oil had a significantly higher antilisterial activity in comparison to O. vulgare oil and chloramphenicol. No significant differences in L. monocytogenes susceptibilities to the essential oils tested were registered. The minimum inhibitory concentration values of T. capitata essential oil and of carvacrol were quite similar, ranging between 0.05 and 0.2 microL/mL. Antioxidant activity was also tested, the essential oil of T. capitata showing significantly higher antioxidant activity than that of O. vulgare. Use of T. capitata and O. vulgare essential oils can constitute a powerful tool in the control of L. monocytogenes in food and other industries. PMID:16218659

    Marrubium vulgare (Lamiaceae) is a medicinal plant whose major bioactive compounds, marrubiin and other labdane-related furanoid diterpenoids, have potential applications as anti-diabetics, analgesics or vasorelaxants. Metabolite and transcriptome profiling of M. vulgare leaves identified five different candidate diterpene synthases (diTPSs) of the TPS-c and TPS-e/f clades. We describe the in vitro and in vivo functional characterization of the M. vulgare diTPS family. In addition to MvEKS ent-kaurene synthase of general metabolism, we identified three diTPSs of specialized metabolism: MvCPS3 (+)-copalyl diphosphate synthase, and the functional diTPS pair MvCPS1 and MvELS. In a sequential reaction, MvCPS1 and MvELS produce a unique oxygenated diterpene scaffold 9,13-epoxy-labd-14-ene en route to marrubiin and an array of related compounds. In contrast with previously known diTPSs that introduce a hydroxyl group at carbon C-8 of the labdane backbone, the MvCPS1-catalyzed reaction proceeds via oxygenation of an intermediate carbocation at C-9, yielding the bicyclic peregrinol diphosphate. MvELS belongs to a subgroup of the diTPS TPS-e/f clade with unusual βα-domain architecture. MvELS is active in vitro and in vivo with three different prenyl diphosphate substrates forming the marrubiin precursor 9,13-epoxy-labd-14-ene, as identified by nuclear magnetic resonance (NMR) analysis, manoyl oxide and miltiradiene. MvELS fills a central position in the biosynthetic system that forms the foundation for the diverse repertoire of Marrubium diterpenoids. Co-expression of MvCPS1 and MvELS in engineered E. coli and Nicotiana benthamiana offers opportunities for producing precursors for an array of biologically active diterpenoids. PMID:24990389

    The hexaploid nature of common wheat (Triticum aestivum vulgare) and triplication of the genes allow a great number of primary induced changes to be present and maintained through generations. Induced mutations have been obtained in the morphological characters of the wheat spike, grain character, plant height, disease resistance, and in many other quantitative characters. In some of our experiments these have been followed through 25 generations. The genetic aspects of these changes, their effect on the micro-evolutionary processes in the populations, and their applicability in plant breeding are discussed. (author). 56 refs

    Full Text Available Marrubium vulgare L., commonly known as a white horehound or common horehound, belongs to the plant family Lamiaceae. It is a perennial aromatic herb which grows naturally in Europe, Asia, and America. Since ancient Egypt, this species has been known as a remedy for upper respiratory tract ailments. Nowadays, horehound is used in herbal medicine for treatment of liver diseases, biliary tract disorders, and for increasing the appetite and supporting the function of the stomach. The main biologically active substances in M. vulgare organs are: marrubiin, tannins, essential oils, and ursolic acid. The paper presents micromorphological analyses of non-glandular and glandular trichomes of M. vulgare. The research material was sampled from the plant collection in the Botanical Garden of the Maria Curie-Sklodowska University in Lublin (51°14′ N, 22°34′ E. The above-ground parts of horehound were collected during the flowering period in July 2013. Using light microscopy (LM and scanning electron microscopy (SEM, the types and sizes of trichomes from the stem, leaf, calyx, and corolla were investigated. The results of the microscopic observations show that the surfaces of M. vulgare vegetative and reproductive organs are densely clothed with glandular and non-glandular trichomes. The glandular trichomes are of two main types: peltate and capitate. Peltate trichomes consist of a short stalk cell and a large head with secretory cells arranged in a circle. The height of a mature trichome is about 31.33 μm and the diameter of the head is 31.47 μm. The substance produced by secretory cells passes through the apical walls and accumulates within a space between the cuticle and the cell wall layer. Capitate long trichomes with a basal cell, long stalk, neck cell, and a unicellular head are 36.65 μm long and the diameter of the head is about 15.6 μm. There are two types of short capitate trichomes: with a bicellular head and a unicellular stalk and with

    Pyrrolizidine alkaloids (PAs) in honey can be a potential human health risk. So far, it has remained unclear whether PAs in honey originate from pollen or floral nectar. We obtained honey, nectar, and plant pollen from two observation sites where Echium vulgare L. was naturally abundant. The PA concentration of honey was determined by targeted analysis using a high pressure liquid chromatography-mass spectrometry system (HPLC-MS/MS), allowing the quantification of six different PAs and PA-N-oxides present in E. vulgare. Echium-type PAs were detected up to 0.153 μg/g in honey. Nectar and plant pollen were analyzed by nontargeted analysis using ultrahigh pressure liquid chromatography-high resolution-mass spectrometry (UHPLC-HR-MS), allowing the detection of 10 alkaloids in small size samples. Echium-type PAs were detected between 0.3-95.1 μg/g in nectar and 500-35000 μg/g in plant pollen. The PA composition in nectar and plant pollen was compared to the composition in honey. Echimidine (+N-oxide) was the main alkaloid detected in honey and nectar samples, while echivulgarine (+N-oxide) was the main PA found in plant pollen. These results suggest that nectar contributes more significantly to PA contamination in honey than plant pollen. PMID:27244472

    Marrubium vulgare (Lamiaceae) is a plant traditionally used for the treatment of diabetes in Algeria. Compositional analysis of the aqueous infusion revealed the presence of fifteen metabolites, all belonging to the class of polyphenols. Particularly, seven flavonoids have been detected, together with 5-caffeoylquinic (chlorogenic) acid in small amounts; the extract is dominated by the presence of a series of complex molecules, characterized as verbascoside (acteoside) derivatives. Concerning the anti-diabetic effectiveness a series of in vivo experiments were carried out on albinos Wistar rats. Diabetes was induced in the animals by intra-peritoneal injection of alloxane; they were treated twice a day with aqueous extract from aerial part infusion (100, 200 and 300 mg/kg body weight) and glibenclamide (5mg/kg body weight) for 15 days. Oral administration of 200 and 300 mg/kg body weight of aqueous extract the Marrubium vulgare induced an significant effect antidiabetic and antihyperlipidemic (dose-dependent effect). A decrease in blood glucose by 50% for the dose 100 mg/kg and more than 60% for doses 200 and 300 mg/kg, as well as a significant lowering of total lipids, triglycerides, and total cholesterol levels in treated animals, compared with diabetic controls group (p<0.001), have been observed. Glibenclamide was used as reference and showed similar effects. PMID:22100836

    We have shown previously that Marrubium vulgare, a medicinal plant employed frequently in folk medicine to treat a variety of ailments, exhibits antispasmodic and antinociceptive effects in different experimental models. This work describes the antinociceptive profile of marrubiin, the main constituent of this plant, which was analysed in some models of nociception in mice. The results showed that marrubiin exhibits potent and dose-related antinociceptive effects, whose calculated ID50 values (micromol/kg, i.p.) were the following: 2.2 in the writhing test, 6.6 (first phase) and 6.3 (second phase) in the formalin-induced pain test and 28.8 when evaluated in the capsaicin test. It was more potent than some well-known analgesic drugs. The antinociception produced by the marrubiin was not reversed by naloxone when analyzed against the writhing test. In the hot-plate test, marrubiin did not increase the latency period of pain induced by the thermal stimuli. Its exact mechanism of action remains to be determined, but the results suggest that marrubiin, like hydroalcoholic extract of M. vulgare, does not interact with opioid systems. PMID:10839213

    In this study, the lipophilic and hydrophilic phenol composition of virgin olive oils (VOO) obtained from olives from two of the most important Portuguese cultivars ('Galega Vulgar' and 'Cobrançosa'), harvested at different ripening stages and under two irrigation schemes (rain fed and irrigated), was evaluated. Phenolic alcohols (hydroxytyrosol and tyrosol), phenolic acids and derivatives and flavonoids (luteolin and apigenin), as well as tocopherols were quantified. Lipophilic (>300mgkg(-1)) and hydrophilic phenols (>600mgkg(-1)) were present in high contents in both VOO, for early ripening stages. Gamma-tocopherol content is higher in 'Galega Vulgar' VOO. Total phenols showed a decrease between ripening index 2.5 and 3.5. The dialdehydic form of elenolic acid linked to hydroxytyrosol (3,4-DHPEA-EDA), also known as oleacein, was the major phenolic compound identified in both oils. The concentration of free hydroxytyrosol and tyrosol in both VOO is very low while their esterified derivatives, like 3,4-DHPEA-EDA and p-HPEA-EDA, are much more abundant. PMID:27283606

    Full Text Available The single and combined effects of copper (Cu and cadmium (Cd (0.1-10 mg L−1 in spring barley (Hordeum vulgare L. plants grown in hydroponics are investigated. The aim of the study was to investigate the interactive effect of the binary mixture of Cu and Cd to the growth of H. vulgare and accumulation of these metals by the plants. Single and combined metal treatment led to major effects in the growth of roots and shoots and dry weight of barley. Exposure to metals altered the content of photosynthetic pigments and caused lipid peroxidation. It was observed that combined effects of heavy metals to plants are endpoint and concentration depending. The binary mixture Cu+Cd exhibited additive or less than additive interaction for dry weight, root length and shoot height. Analysis of tissue metal concentrations showed that Cu and Cd were mainly accumulated in the roots and the combination of Cu+Cd had less than additive response of metal bioaccumulation in the leaves and roots.

    Pythium insidiosum is the etiologic agent of pythiosis, a severe and emerging disease that affects mammals. Failure of conventional antifungal therapies is partially justified by the absence of ergosterol in the plasma membrane of this oomycete. Despite research advancement, the treatment of pythiosis has not been not fully established. The present study investigated the in vitro susceptibility profile of Brazilian isolates of P. insidiosum (n = 20) against Melaleuca alternifolia, Mentha piperita and Origanum vulgare essential oils, and their combinations. Susceptibility tests were performed according to CLSI M38-A2 protocol, and combinations were evaluated by the microdilution cherkerboard method. All tested essential oils showed antimicrobial activity against P. insidiosum, and the greatest activity of O. vulgare was highlighted. Synergistic and/or indifferent effect was observed for all combinations evaluated, especially the M. piperita and O. vulgare combination, which showed 65 % synergism. This is the first study to report in vitro combinations of essential oils against P. insidiosum indicating the susceptibility of this oomycete to M. alternifolia, M. piperita and O. vulgare essential oils, as well as their combinations.

    Full Text Available SDS-PAGE was used to analyze the hordein polypeptide patterns of Brazilian barley varieties (Hordeum vulgare L. and of two native species of Hordeum from southern Brazil (H. euclaston Steud. and H. stenostachys Godr.. Forty different hordein polypeptide bands with molecular weights ranging from 30 to 94 kDa were found in the seeds of the three species studied. Twelve of the 14 varieties examined showed intravarietal polymorphism. The number of bands ranged from 10 to 17, depending on the variety, and from 3 to 13 among individual seeds, with a total of 26 bands in H. vulgare. Phenograms using each seed as an operational taxonomic unit (OTU showed that the seeds from most varieties did not form distinct clusters. Seeds from different plants of the native species varied considerably. The molecular weights of the hordein polypeptides of the two native species were quite different from those of H. vulgare. There was a greater similarity between the native species than with H. vulgare, although H. stenostachys was slightly closer to the cultivated species than H. euclaston.

    Full Text Available Abstract Background In order to validate its antiseptic and anticancer properties with respect to traditional uses, we have screened for the first time the antimicrobial activity of aerial parts of M. vulgare L. essential oil against different pathogenic microorganisms and the cytotoxic activity against HeLa cell lines. Methods The agar disk diffusion method was used to study the antibacterial activity of M. vulgare essential oil against 12 bacterial and 4 fungi strains. The disc diameters of zone of inhibition (DD, the minimum inhibitory concentrations (MIC and the concentration inhibiting 50% (IC50 were investigated to characterize the antimicrobial activities of this essential oil. The in vitro cytotoxicity of M. vulgare essential oil was examined using a modified MTT assay; the viability and the IC50 were used to evaluate this test. Results The antimicrobial activity of the essential oil was investigated in order to evaluate its efficacy against the different tested microorganisms. The present results results showed a significant activity against microorganisms especially Gram (+ bacteria with inhibition zones and minimal inhibitory concentration values in the range of 6.6-25.2 mm and 1120-2600 μg/ml, respectively, whereas Gram (- bacteria exhibited a higher resistance. As far as the antifungal activity, among four strains tested, Botrytis cinerea exhibited the strongest activity with inhibition zones of 12.6 mm. However, Fusarium solani, Penicillium digitatum and Aspergillus niger were less sensitive to M. vulgare essential oil. About the citotoxicity assay, this finding indicate the capability of this essential oil to inhibited the proliferation of HeLa cell lines under some conditions with IC50 value of 0.258 μg/ml. Conclusion This investigation showed that the M. vulgare essential oil has a potent antimicrobial activity against some Gram (+ pathogenic bacteria and Botrytis cinerea fungi. The present studies confirm the use of this

    The European grapevine moth (EGVM),Lobesia botrana, is a major pest of grapes in Europe. Females are attracted to a nonhost plant: tansy (Tanacetum vulgare L.), which is a common weed in Slovakian vineyards. A steam distillate extract of tansy flowers was analyzed by means of a GC-EAG technique to screen constituents detected by the olfactory receptors of EGVM females. From more than 200 GC peaks, nine peaks corresponding to monoterpenoids released an EAG response in more than 70% of the females (N=15):p-cymene,d-limonene,α-thujene,α-thujone,β-thujone, thujyl alcohol, terpinene-4-ol, (Z)-verbenol, and piperitone. The steam distillate of tansy as well as a synthetic blend of identified compounds released consistent attraction in a field cage. The use of nonhost plants and host plant odors in integrated pest management is discussed. PMID:24253963

    Full Text Available Human subjects with active vulgar vitiligo do not respond well to autologous dermo-epidermal minigrafting. Eighteen subjects were treated with the a-melanocyte-stimulating hormone (a-MSH synthetic analogue [Nle4, D-Phe7]-a-MSH. The hormone (50 ml, 0.4 mM was applied topically to 30-cm2 lesions in which 29-48 minigrafts had been made. The hormone did not improve the success of the minigrafting and no differences were observed in local or distant repigmentation in treated subjects as compared to the placebo group. Aliquots of 24-h urine concentrated by lyophilization irreversibly darkened toad skins, demonstrating the presence of the analogue. This is the first report of the transdermal delivery of a topically applied melanotropin in living human subjects.

    Full Text Available Essential oils are well known as strong antimicrobial agents of plant origin. In spite of this, the antimicrobial synergism of essential oils isolated from different plant species is poorly investigated. The following study examines the synergism of the essential oils of Origanum vulgare L. and Thymus vulgaris L against pathogenic bacteria, Staphylococcus aureus and Salmonella typhimurium. First, the antibacterial effect of the oils was tested, and the minimal inhibitory concentrations (MIC of both oils were determined using the microdilution method. To test whether the oils act synergistically, every possible combination of essential oil concentrations was used in a dynamic checkerboard method. The results indicated that the oils indeed acted synergistically with fractional inhibitory concentration indexes of 0.45 and 0.50. [Projekat Ministarstva nauke Republike Srbije, br. 173032

    1998-05-01

    Accumulation of furanic labdane diterpenes has been investigated in different parts of field-grown plants of MARRUBIUM VULGARE (Lamiaceae) and LEONURUS CARDIACA (Lamiaceae). Furanic labdane diterpenes were produced and accumulated only in the aerial parts. Greatest amounts were measured in leaves and flowers. Up to 4 mg furanic labdane diterpenes per g fresh weight were found. Accumulation of furanic labdane diterpenes in plantlets seemingly depends on a developmental programme. No furanic labdane diterpenes were detected in plantlets during the first four to five weeks following germination. At this time the leaves became more differentiated and the number of trichomes on leaves was obviously increasing. Young leaves and buds contained most furanic labdane diterpenes. It was proven that at least a part of the non-volatile furanic labdane diterpenes is stored in peltate glandular trichomes. NMR signals of marrubiin were investigated with correlated spectra. Some (1)H- and (13)C-NMR assignments reported in literature were revised. PMID:17253250

    The whole plant of Marrubium vulgare L. afforded a new terpenoid, characterised as p-menthane-5,6-dihydroxy-3-carboxylic acid (1), which has been designated as marrubic acid. Its structure has been elucidated on the basis of spectral and chemical analyses. The compound (1) also exhibited a significant antihepatotoxic activity by reducing the elevated levels of serum enzymes such as serum glutamate oxaloacetate transaminase (SGOT) by 40.16%, serum glutamate pyruvate oxaloacetate transaminase (SGPT) by 35.06%, and alkaline phosphatase (ALP) by 30.51%. On the other hand, total protein (TP) levels were increased by 34.07%, as compared to the standard drug silymarin, which decreased SGOT by 53.04%, SGPT by 55.96%, ALP by 35.87% and increased TP levels by 59.59%. These biochemical observations were also supplemented by histopathological examinations of liver sections. PMID:20628963

    Marrubiin, a furane labdane diterpene, is the main analgesic compound present in Marrubium vulgare, a medicinal plant used in Brazil and other countries to treat several ailments. Considering its important pharmacological action, as well as its high yield, some structural modifications were performed in order to obtain more active compounds. Success was obtained in reducing the lactonic function, in the formation of marrubiinic acid and two esterified derivatives, which exhibited significant analgesic effect against the writhing test in mice. Marrubiinic acid showed better activity and excellent yield, and its analgesic effect was confirmed in other experimental models of pain in mice, suggesting its possible use as a model to obtain new and potent analgesic agents.

    Oregano (Thymbra capitata and Origanum vulgare) essential oils (EOs), cultivated and extracted in the South-East of Spain, were analysed by GC/MS to determine their composition. (E)-β-Caryophyllene (0.5-4.9%), thymol (0.2-5.8%), p-cymene (3.8-8.2%), γ-terpinene (2.1-10.7%) and carvacrol (58.7-77.4%) were determined as the main molecules. This characterisation was completed with enantioselective gas chromatography, where (-)-(E)-β-caryophyllene, (+)-a- pinene and (+)-β-pinene were determined as the main enantiomers. Antioxidant activity was evaluated positively by several methods, accounting for activity against free radicals and reducing power. Important inhibitory activity on lipoxygenase (LOX) and acetylcholinesterase (AChE) was observed supporting potential anti-inflammatory, anti-Alzheimer and insecticidal activities, mainly due to carvacrol. These properties support the potential use of oregano EOs as natural cosmetic and natural pharmaceutical ingredients. PMID:26996035

  6. Trace elements and essential oil composition in chemotypes of the aromatic plant Origanum vulgare

    International Nuclear Information System (INIS)

    Trace elements, essential oil yield and its percentage composition were determined by neutron activation analysis, hydrodistillation and gas chromatography in two chemotypes of Origanum vulgare L. cultivated in the same field. Statistical tests such as analysis of variance, correlation coefficient, t-test, and multiple correlation were applied. The results showed that the samples contain the highest recorded oil yield for aromatic plants. Also, there is a statistically significant difference between the chemotypes of the plant not only in the predominant compound but in a number of other components. Iron, chromium and scandium showed a negative significant correlation with carvacrol and a positive one with thymol. Europium shows characteristic correlations with chromium, cobalt, iron and scandium within each chemotype of the plant. These correlations could make probable a role of this element in the biosynthesis of the predominant compounds. (author)

    The potential of chitosan as a possible booster of the antimicrobial activity of Origanum vulgare EO (OEO) against spoilage bacteria and Listeria monocytogenes was investigated in fresh pork meat. Pork fillets were inoculated with 3 L. monocytogenes strains, dipped either in Origanum vulgare (oregano) Essential Oil (OEO) at 2 and 4%, or in chitosan 1% alone or added with 2 and 4% OEO, then packed under modified atmosphere (70% O2, 20% CO2, 10% N2) and stored at 4 °C for 15 days. OEO did not reduce L. monocytogenes growth, while 2 Log decrease was obtained after 2 days of storage in treatments with chitosan alone or with OEO, with growth inhibition up to day 15 in samples with chitosan and OEO 4%. When OEO was combined with chitosan, total viable counts and spoilage bacteria were reduced and contained over time, particularly Pseudomonas (2.0 Log CFU/g at day 15) and Brochothrix thermosphacta (undetectable). All the treatments applied extended meat shelf-life with respect to control, whose commercial shelf-life was 10 days. Chitosan treatments enhanced L* and maintained a* values almost stable during storage. Chitosan and OEO singly applied reduced lipid oxidation (0.62-0.75 mg malondialdehyde/Kg meat) compared to control (0.99 mg malondialdehyde/Kg meat). Finally, chitosan treated samples were not recognized with respect to the control, whereas OEO gave bitter taste; chitosan with OEO instead mitigated the effect of OEO addition to meat. Chitosan combined with OEO boosts its antimicrobial activity and shows a potential for application in industrial production of fresh pork in MAP, to achieve shelf-life extension, control of L. monocytogenes growth, stability of color and protective effect from oxidation, with low sensory impact.

    Endornaviruses are unusual plant-, fungus- and oomycete-infecting viruses with a large, ca 14- to 17-kb linear double-stranded RNA (dsRNA) genome and a persistent lifestyle. The complete genome sequence of an endornavirus from the barley (Hordeum vulgare) Nerz variety was determined from paired Illumina MySeq reads derived from purified dsRNAs. The genome is 14,243 nt long, with 5' and 3' non-coding regions of 207 and 47 nt, respectively. It encodes a single large protein of 4663 amino acids that carries conserved motifs for a methyltransferase, a helicase and an RNA-dependent RNA polymerase. The sequence of Hordeum vulgare endornavirus (HvEV) carries all the hallmarks of a typical member of the genus Endornavirus, with the exception of an UDP-glycosyltransferase motif observed in many, but not all, endornaviral genomes.

    Cadmium tolerance of three populations of Echium vulgare L., naturally occurring on two Zn-Pb waste deposits (metallicolous populations M1, M2) and on an uncontaminated site (non-metallicolous population, NM) was investigated. The plants were cultivated in hydroponics at 0, 5, 15, 30, or 50μM Cd for 14 days. Although Cd reduced the content of photosynthetic pigments indifferently in the three populations, plant growth parameters and root viability analyses confirmed different Cd tolerances decreasing in the order M1>M2>NM in the populations studied. Organic acids (tartrate, malate, citrate, succinate) were not responsible for the elevated Cd tolerance of the metallicolous populations, although malate and citrate might participate in Cd detoxification in the roots of the M1 and M2. Phytochelatin concentrations were higher in the roots of M1 and M2 populations of E. vulgare, suggesting their role in Cd detoxification and different Cd tolerances. PMID:24732029

    Salt stress is a major adverse factor that can lower seed germination and seedlings growth, leading to reduced plant growth and ultimately lower crop productivity in arid and semi arid regions of the world. Tomato (Solanum lycopersicum L.) is an important crop occupying a large area in both Morocco and Tunisia, where salt stress is the most limiting factor. In the present investigation, an attempt has been made to study the effect of seaweed liquid extract (SWE) from Sargassum vulgare at diff...

    MicroRNAs (miRNA) are a class of small, endogenous RNAs that play a negative regulatory role in various developmental and metabolic processes of plants. Wild barley (Hordeum vulgare subsp. spontaneum), as the progenitor of cultivated barley (Hordeum vulgare subsp. vulgare), has served as a valuable germplasm resource for barley genetic improvement. To survey miRNAs in wild barley, we sequenced the small RNA library prepared from wild barley using the Illumina deep sequencing technology. A total of 70 known miRNAs and 18 putative novel miRNAs were identified. Sequence analysis revealed that all of the miRNAs identified in wild barley contained the highly conserved hairpin sequences found in barley cultivars. MiRNA target predictions showed that 12 out of 52 miRNA families were predicted to target transcription factors, including 8 highly conserved miRNA families in plants and 4 wheat-barley conserved miRNA families. In addition to transcription factors, other predicted target genes were involved in diverse physiological and metabolic processes and stress defense. Our study for the first time reported the large-scale investigation of small RNAs in wild barley, which will provide essential information for understanding the regulatory role of miRNAs in wild barley and also shed light on future practical utilization of miRNAs for barley improvement.

    Isoproterenol injection (100 mg/kg; sc) produced changes in ECG pattern including ST-segment elevation and suppressed R-amplitude. The methanolic extract of M. vulgare at doses of 10, 20, and 40 mg/kg significantly amended the ECG changes. A severe myocardial necrosis and edematous along with a sharp reduction in the arterial blood pressure, left ventricular contractility (LVdP/dt(max or min)), but a marked increase in the left ventricular end-diastolic pressure (LVEDP) were seen in the isoproterenol group. All parameters were significantly improved by the extract treatment. The extract (10 mg/kg) strongly increased LVdP/dt(max). Similarly, treatment with 40 mg/kg of M. vulgare lowered the elevated LVEDP and the heart to body weight ratio. In addition to in vitro antioxidant activity, the extract suppressed markedly the elevation of malondialdehyde levels both in serum and in myocardium. The results demonstrate that M. vulgare protects myocardium against isoproterenol-induced acute myocardial infarction and suggest that the effects could be related to antioxidant activities.

    The pathological hallmark of Alzheimer's disease is the accumulation of Aβ peptides in human brains. These Aβ peptides can be degraded by several enzymes such as hACE, hECE, hIDE and cathepsin B. Out of which cathepsin B also belongs to the papain super family and has been found in human brains, it has a role in Aβ peptide degradation through limited proteolysis. The Aβ concentrations are maintained properly by its production and clearance via receptor-mediated cellular uptake and direct enzymatic degradation. However, the reduced production of Aβ degrading enzymes as well as their Aβ degrading activity in human brains initiate the process of accumulation of Aβ peptides. So it becomes essential to investigate the molecular interactions involved in the process of Aβ degradation in detail at the atomic level. Hence, homology modeling, molecular docking and molecular dynamics simulation techniques have been used to explore the possible role of cathepsin B from Hordeum vulgare in the degradation of amyloid beta (Aβ) peptides. The homology model of cathepsin B from Hordeum vulgare shows good similarity with human cathepsin B. Molecular docking and MD simulation results revealed that the active site residues Cys32, HIS112, HIS113 are involved in the catalytic activity of cathepsin B. The sulfhydryl group of the Cys32 residue of cathepsin B from Hordeum vulgare cleaves the Aβ peptide from the carboxylic end of Glu11. Hence, this structural study might be helpful in designing alternative strategies for the treatment of AD. PMID:26568474

    Full Text Available Generation mean analysis was performed using three crosses namely DL 88 x K 560, K 603 x Azad, RD 2552 x NDB 1020 to study the nature and magnitude of gene effects for yield and its component characters in barley (Hordeum vulgare L.. The F1, F2, BC1 and BC2 of these crosses along with P1 and P2 were studied for six morphological traits. Additive x additive (i epistatic effect was more important and higher than the dominance x dominance (l epistatic effect in the inheritance of no. of effective tillers/plant in DL88 x K560, length of main spike and grain yield/plant in RD 2552 x NDB1020. The length of main spike, weight of grains/main spike, 1000-grain weight and grain yield/plant were significantly higher in RD 2552 x NDB 1020.Thus, these characters were mainly under the control of dominance x dominance (l type of epistasis. Therefore, selection for these characters would be fruitful, if delayed till dominance and epistasis effects are reduced to minimum. The additive × additive (i type gene interaction and duplicate epistasis also seen in this trait suggest the possibilities of obtaining transgressive segregants in later generations. The study revealed the importance of both additive and non-additive types of gene interaction for all the traits studied.

  9. Barley (Hordeum vulgare) and Kiwicha (Amaranthus caudatus) Improvement by Mutation Induction in Peru

    International Nuclear Information System (INIS)

    In order to increase food availability and household incomes of families in the Andean region of Peru, a mutation induction method was applied to improve barley (Hordeum vulgare) and kiwicha (Amaranthus caudatus) cultivars. Barley cultivar Buenavista was treated with 200 and 300Gy inducing different kinds of mutations. Twenty promising mutant lines were selected and have been evaluated at the national trials. From them Mbv-Earlier, from 300Gy dose was selected and released in 2006 as a new cultivar denominated Centenario. This cultivar has a high yield potential (5,552 kg/ha), resistance to stripe rust (P. striiformis f sp hordei) and better food quality than the parental cultivar. Kiwicha traditional cultivar Seleccion Ancash treated with 400Gy , identified a higher yield mutant denominated Centenario Cultivar. At farmer location in the coast the yield has a variation of 3,500 to 5,500 kg/ha and in the highland from 2,500 to 3,700 kg/ha. The better yield potential, tolerance to Sclerotinia sp, color and size of its grains have contributed in the preference of Centenario over other commercial cultivars. (author)

    Any improvement in agricultural systems that results in higher production should also reduce negative environmental impacts and enhance sustainability. The aim of this research was to investigate the effect of two different production systems, one open-field and the other shade-enclosure with four bocashi doses, in order to find the best environmental option in terms of yield, physiological and morphometric characteristics in one oregano (Origanum vulgare L.) cultivar. In this study a completely randomized block design was used with four replications and evaluated for photosynthetic and transpiration rate, stomatal conductance, chlorophyll, leaf area and temperature, aerial and roots fresh and dry biomass, fresh and dry yield. The results showed that oregano adapted best to the shade-enclosure with increase yield of fresh and dry leaf weight of 165% and 118%, respectively, when compared to open-field. Also, higher doses of bocashi improved yield in both environments but more so in shade-enclosure. Soil moisture retention was higher in shade-enclosure which was reflected in physiological variables for soil matric potential, transpiration, stomatal conductivity, photosynthesis being significantly higher in shade-enclosure compared to open-field, thus improving yield. It seems that oregano plants can be grown and perform better under shade-enclosure than open-field and bocashi is a suitable organic fertilizer. PMID:26257756

  11. Treatment of patients with vulgar psoriasis through electromagnetic field of extremely low frequency

    International Nuclear Information System (INIS)

    A controlled and randomized clinical therapeutical assay in phase III was carried out in 52 patients with vulgar psoriasis, who were assisted in the Dermatology department of 'Dr Joaquin Castillo Duany' Clinical Surgical Hospital in Santiago de Cuba, from 2005 to 2010 who were divided into 2 groups (26 members each): the active group which was conventionally treated with 20% cade ointment; and the experimental group, to which the extremely low frequency electromagnetic field was applied, with the objective of determining the effectiveness of this field in those affected during the periods of crisis and intercrisis. The studied population was clinically characterized by means of a frequency analysis, while the hypothesis tests were used for the evaluation of proportions which null hypothesis were accepted with 5 % as maximum error. In the series the used field was effective to treat the disorder during crisis and more effective than the cade ointment to prolong the intercrisis stage, without causing adverse reactions, so that it constituted a new alternative therapy that can be generalized in the dermatological services of the country, in order to improve the life quality of those who suffer that dermatosis

  12. Reduction of gramine concentration by gamma-irradiation in seedlings of Hordeum vulgare var. Amaginijo

    International Nuclear Information System (INIS)

    The effects of gamma-irradiation on gramine concentration in seedlings of barley (Hordeum vulgare var. Amaginijo) were investigated. Similarly to other barley cultivars, this amine appeared in shoots of sprouting seedlings and its concentration increased in the course of subsequent development to attain a maximum around the ninth day. Exposure of two-day-old seedlings to gamma-radiation resulted in significant reductions of the concentration as compared with non-irradiated control, dependent upon the radiation dose, whilst the five-day-old seedlings were slightly affected. Seeds were more radioresistant than younger seedlings, when the decline in gramine quantity was taken as a marker of radiation effect. Longer storage of irradiated seeds enhanced the decrease of this compound in seedlings. At relatively low doses, gramine concentration was successively recovered to reach the control level during further growth. This decline of gramine content could not be correlated solely with water content of seeds and oxygen did not seem to be a critical factor. On the basis of these results, probable mechanisms for radiation-induced reduction of the amine concentration are discussed. In these experiments it was found that changing patterns of gramine content were in close parallel with those of growth

    The genetic sources for host-plant resistance to the greenbug (Schizaphis graminum Rondani) in barley (Hordeum vulgare ssp. spontaneum) are limited in that only two single dominant genes Rsg1 and Rsg2 are available for the complex of greenbug biotypes. We evaluated four new barley lines from the Wild Barley Diversity Collection (WBDC) that previously showed potential for greenbug resistance. Three of those entries, WBDC 53, WBDC 117, WBDC 336, exhibited very dominant sources of resistance to older known biotypes B, C, E, F, H, I, and TX1, which also add to the host-plant differentials used to separate these greenbug biotypes. We also re-evaluated the earlier known set of greenbug biotypes that have been in culture for several years against the known host-plant differentials, and included seven newer greenbug isolates collected from Wyoming to the full complement of small grain differentials. This resulted in the discovery of five new greenbug biotypes, WY10 MC, WY81, WY10 B, WY12 MC, and WY86. Wyoming isolates WY4 A and WY4 B were identical in their phenotypic profile, and should be combined as a single unique greenbug biotype. These barley trials resulted in finding new sources of host-plant resistance, although more research needs to be conducted on what type of resistance was found, and how it can be used. We also document that the Wheatland, Wyoming area serves as a very conducive environment for the development of new greenbug biotypes. PMID:26527793

    Oregano is a perennial shrub that grows in the mountains of the Mediterranean and Euro/Irano-Siberian regions. This study was conducted to identify the major constituents of the ethanolic Origanum vulgare extract and examine the cytotoxic, antioxidant, and antibacterial properties of the extract but more importantly the contribution of its specific major constituent(s) or their combination to the overall extract biological activity. Gas chromatography/mass spectroscopy analysis showed that the extract contained monoterpene hydrocarbons and phenolic compounds, the major ones being carvacrol and thymol and to a lesser extent p-cymene, 1-octacosanol, creosol, and phytol. A549 epithelial cells challenged with the extract showed a concentration-dependent increase in cytotoxicity. A combination of thymol and carvacrol at equimolar concentrations to those present in the extract was less cytotoxic. The A549 cells pretreated with nonlethal extract concentrations protected against hydrogen-peroxide-induced cytotoxicity, an antioxidant effect more effective than the combination of equimolar concentrations of thymol/carvacrol. Inclusion of p-cymene and/or 1-octacosanol did not alter the synergistic antioxidant effects of the carvacrol/thymol mixture. The extract also exhibited antimicrobial properties against Gram-positive and Gram-negative bacterial strains including clinical isolates. In conclusion, the oregano extract has cytotoxic, antioxidant, and antibacterial activities mostly attributed to carvacrol and thymol. PMID:27051475

  16. Evaluation of barley (hordeum vulgare l.) germplasm for high forage production under salt stress

    International Nuclear Information System (INIS)

    To explore high biomass producing salt tolerant cultivars of a potential forage crop barley (Hordeum vulgare L.), 30-day old plants of 105 different accessions from different origin were subjected to saline and non-saline (control) conditions for 45 days. Salinity stress (150 mM NaCl) markedly suppressed plant growth (shoot and/or root fresh and dry weights), chlorophyll pigments (a and b), internal CO/sub 2/ concentration, stomatal conductance, rate of transpiration and photosynthesis, while a considerable salt-induced increase was observed in all fluorescence related attributes including efficiency of photosystem-II (Fv/Fm), co-efficient of non-photochemical quenching (QN), photochemical quenching (QP), and non-photochemical quenching (NPQ) in all 105 accessions of barley. The response of all 105 barley accessions to salt stress varied significantly for all the morpho-physiological attributes determined in the present study. Overall, on the basis of shoot and root dry weights, accessions, 4050, 4053, 4056, 4163, 4228, 4229, 4244, 4245, 4290, 4414, 4415, 4427, 4452, Mahali, Jesto, 4165, 4229, 4249, 4405, 4409, 4426, 4456, and Giza 123 were found superior while accessions, 4245, 4158, 4166, 4246, 4406, 4423, 4441, 4442 4447, 4453 and 4458 inferior under saline conditions.

  17. Auxin effects on somaclonal variation and plant regeneration from mature embryo of barley (hordeum vulgare L.)

    International Nuclear Information System (INIS)

    Crop improvement through genetic engineering depends on effective and reproducible plant regeneration systems. In barley (Hordeum vulgare L.), immature embryos are the most commonly used as explant source for In vitro regeneration and genetic transformation but, mature embryos are alternative to immature embryo due to the fact that they have advantages such as easy storage and ready availability throughout the year. The effects of different concentrations (2, 4, 6, 8, 10 and 12 mg/l) of three auxins (2,4-D, dicamba and picloram) were evaluated in mature embryo culture of barley. Calli, embryogenic calli and regenerated plants were observed in all of the studied auxins. The MS (Murashige and Skoog basal medium) containing 12 mg/l dicamba was found to be the most effective for embryogenic callus, responded embryogenic callus and regeneration efficiency. Plant tissue culture can bring about genetic changes that are known as somaclonal variation. Genetic and epigenetic changes were examined by RAPD (Randomly Amplified Polymorphic DNA) and CRED-RA (Coupled Restriction Enzyme Digestion-Random Amplification) techniques, respectively. Increased auxin concentration led to the decrease in the GTS (Genomic Template Stability) value. DNA hypermethylation occurred in higher concentrations of 2,4-D and picloram, while DNA hypomethylation was observed in dicamba. (author)

    Full Text Available Triticum vulgare (Wheat based products are the major dietary source of food in developing countries. In India, it grows in association with boundary plantations of Populus deltoids (poplar. During winter, poplar enters in dormancy which cause a heavy leaf fall at the time of wheat seed germination. Large number of poplar senescence leaves may adversely affect the wheat. Therefore, the present study was performed to examine the effect of senescence poplar leaves on wheat germ and some other biochemical parameters. Seed’s germination rate was determined by measuring root and shoot lengths, percent germination, germination index, and inhibition percentage. Biochemical parameters, namely, pigment, carbohydrate, protein, and phenol content, were estimated. Activities of catalase and polyphenol oxidase which are stress marker enzymes were also measured. Results revealed that germination and other biochemical parameters of wheat were severely affected by senescence poplar leaves even at very low concentration. So, intercropping of poplar along with wheat may be chosen carefully as wheat is the major dietary staple.

    Full Text Available This paper deals with the analysis of toxic effects of cadmium and copper on the growth of spring barley (Hordeum vulgare L. cultivated in hydroponics. The seedlings of barley were treated with four different concentrations of cadmium and copper, ranging from 0.1 to 10 mg L-1. The aim of the study was to assess toxic effects of cadmium (Cd and copper (Cu on the growth of spring barley, and to determine metal accumulation in above-ground and underground parts of the plant. The impact of Cu and Cd on photosynthetic pigments (chlorophyll a, b, the content of malondialdehyde (MDA, and the essential micronutrients (Mn, Fe were examined. Metal treatment reduced the growth of roots (by 60%, shoots (Cd – 48 %, Cu – 57% and dry weight (Cd – 47 %, Cu – 52% of barley. Exposure to metals altered the content of photosynthetic pigments and caused lipid peroxidation. Regression analysis revealed that there was significant negative relationship between MDA content and biomass of barley treated with Cu (r=-0.99, p=0.01. The examined heavy metals were accumulated mainly in the roots and bioconcentration of Cu there was higher than that of Cd, indicating that roots tended to accumulate higher amounts of Cu than Cd. Though translocation of Cd from roots to above-ground tissues was higher, higher levels of Cd were observed in leaves.DOI: http://dx.doi.org/10.5755/j01.erem.64.2.1951

    Comparative cytogenetic analysis was performed with four alloplasmic recombinant (Hordeum vulgare)-Triticum aestivum lines differing in morphological traits, number of seeds per spike, and seed plumpness. None of the lines displayed introgression of the barley genetic material: the karyotypes included only common wheat chromosomes. Two lines, 79(B) and 79(D), were cytogenetically stable. Plants of lines 79(A) and 79(C) displayed a high frequency of unbalanced chromosome aberrations, including dicentric and polycentric chromosomes, terminal deletions varying in size, acentric fragments, and multiple unidentifiable translocations. Previous studies of the mitochondrial genome showed that the two cytologically unstable lines, which were also unstable in fertility and viability, are characterized by heteroplasmy at the mitochondrial 18S-5S locus (simultaneous presence of barley and wheat fragments). Stable lines 79(B) and 79(D) with normal fertility contained only wheat mitochondrial markers. It was assumed that the substantial instability of the nuclear genome in lines 79(C) and 79(A) was a result of nuclear-cytoplasmic incompatibility and was associated with heteroplasmy, while elimination or considerable reduction of barley material in the mitochondrial genome stabilized the nuclear genome of lines 79(B) and 79(D). In turn, the instability of the nuclear genome was responsible for a decrease in viability and fertility of plants. PMID:16583704

    Three methoxylated flavones isolated from Marrubium peregrinum - ladanein, scutellarein-5,7,4'-trimethyl ether, and scutellarein-5,6,7,4'-tetramethyl ether - were assayed for their cytotoxicity towards a recently developed dasatinib-resistant murine leukemia cell line (DA1-3b/M2 (BCR-ABL)), together with the structurally related non-methylated flavone scutellarein. The most active compound, ladanein, was looked for in 20 common Lamiaceae species by a quick HPLC screening. Among the possible positive results, the most interesting source was found to be Marrubium vulgare, which led to the isolation and identification of ladanein for the first time in this species. Ladanein also displayed moderate (20-40 microM) activities against K562, K562R (imatinib-resistant), and 697 human leukemia cell lines but was toxic neither to MOLM13 nor to human peripheral blood mononuclear cells. This work provides a common natural source for the hemi-synthesis of future ladanein-derived flavones and the study of their antileukemic activity. PMID:19644796

    The aim of this study was to investigate the bioactivity of the essential oil isolated from Origanum vulgare L. (EOv). We analyzed the in vivo anti-inflammatory properties in a mouse-airway inflammation model and the in vitro antimicrobial activity, genotoxicity over the anaphase-telophase with the Allium cepa strain and its cytotoxicity/viability in A549 culture cells. In vivo, EOv modified the levels of tumor necrosis factor -α and viable activated macrophages and was capable to mitigate the effects of degradation of conjugated dienes. In vitro, EOv reduced the viability of cultured A549 cells as well as the mitotic index and a number of chromosomal aberrations; however, it did not change the number of phases. We found that EOv presents antimicrobial activity against different Gram (-) and (+) strains, measured by disc-diffusion test and confirmed with a more accurate method, the AutoCad software. We postulate that EOv presents antibacterial, antioxidant and chemopreventive properties and could be play an important role as bioprotector agent. PMID:25266989

    Full Text Available In the present study, genetic diversity in seven cultivars of cultivated barley (Hordeum vulgare populations was evaluated using 10 microsatellite markers. Genomic DNA was extracted from fresh leaves and amplification reactions were done by PCR. The amplification products were separated on 6% denaturing polyacrylamide gels containing 7M urea and visualized via silver staining method. High level of polymorphism was observed among populations. Polymorphic bands ranged from 100 to 300 bp. Altogether 65 alleles were observed among all genotypes, with an average of 9.2 alleles per locus for all loci. Polymorphic information content (PIC ranged from 0.80 to 0.88 with an average of 0.84. �Sahand� populations showed the lowest mean of gene diversity whereas the highest mean of heterozygosity observed in Rayhan populations that can prepare a powerful resource of genetic diversity for breeding programs. The genotypes were clustered using unweight pair-group method on arithmetic average by POPGEN32 software. The dendrogram discriminated all the genotypes in several groups. The results showed that SSR markers have a high ability to reveal most of the information in a single locus and can be used for genetic analysis in molecular levels determination of genetic similarity and clustering barley cultivars.

    The major environmental impact of landfills is emission of pollutants via the leachate and gas pathways. The hepatopancreas of the terrestrial isopod Armadillidium vulgare (Isopoda, Crustacea, Latreille 1804) plays an important role in the bioaccumulation of contaminants, such as heavy metals. To evaluate the effects of landfill leachate treatment, 2 different approaches were applied: 1) the detection of accumulation of trace elements (As, Cd, Cr, Cu, Sb, Zn, Pb, Ni, V) in hepatopancreatic cells, and 2) the evaluation of biological effect of contaminants on fresh hepatopancreatic cells by flow-cytometric analyses. The presence of 2 different cell types (herein referred to as "small" [S] cells and "big" [B] cells, in agreement with the literature based on morphological examinations) was detected for the first time by flow cytometry, which also highlighted their different response to stress stimuli. In particular, B cells appeared more sensitive to landfill leachate treatment, being more damaged in the short term, while S cells seemed more adaptive. Furthermore, S cells could represent a pool from which they are able to differentiate into B cells. These findings were also confirmed by principal component analyses, underlining that S SYBR Green I bright cells correlate with specific chemicals (Ca, Cu, Co), confirming their resistance to stress stimuli, and suggesting that the decrease of specific cell types may prime other elements to replace them in a homeostasis-preservation framework.

    Full Text Available The aim of this study is to examine the growth inhibitory effects of methanolic leaf and fruit extracts of L. vulgare on HCT-116 cells over different time periods and their synergistic effect with a Pd(apox complex. The antiproliferative activity of plant extracts alone or in combination with the Pd(apox complex was determined using MTT cell viability assay, where the IC50 value was used as a parameter of cytotoxicity. Results show that antiproliferative effects of L. vulgare extracts increase with extension of exposure time, with decreasing IC50 values, except for 72 h where the IC50 values for methanolic leaf extract were lower than for the fruit extract. The Pd(apox complex alone had a weak antiproliferative effect, but combination with L. vulgare extracts caused stronger effects with lower IC50 values than with L. vulgare extracts alone. The type of cell death was explored by fluorescence microscopy using the acridin orange/ethidium bromide method. Treatments with plant extracts caused typical apoptotic morphological changes in HCT-116 cells and co-treatments with Pd(apox complex caused higher levels of apoptotic cells than treatment with plant extracts alone. The results indicate that L. vulgare is a considerable source of natural bioactive substances with antiproliferative activity on HCT-116 cells and which have a substantial synergistic effect with the Pd(apox complex.

    Photosynthesis is a biological process most affected by water deficit. Plants have various photosynthetic mechanisms that are matched to specific climatic zones. We studied the photosynthetic plasticity of C3 plants at water deficit using ecotypes of Marrubium vulgare L. from high (2,200 m) and low (1,100 m) elevation sites in the Mishou-Dagh Mountains of Iran. Under experimental drought, high-altitude plants showed more tolerance to water stress based on most of the parameters studied as compared to the low-altitude plants. Increased tolerance in high-altitude plants was achieved by lower levels of daytime stomatal conductance (g s) and reduced damaging effect on maximal quantum yield of photosystem II (PSII) (F v /F m ) coupled with higher levels of carotenoids and non-photochemical quenching (NPQ). High-altitude plants exhibited higher water use efficiency (WUE) than that in low-altitude plants depending on the presence of thick leaves and the reduced daytime stomatal conductance. Additionally, we have studied the oscillation in H(+) content and diel gas exchange patterns to determine the occurrence of C3 or weak CAM (Crassulacean acid metabolism) in M. vulgare through 15 days drought stress. Under water-stressed conditions, low-altitude plants exhibited stomatal conductance and acid fluctuations characteristic of C3 photosynthesis, though high-altitude plants exhibited more pronounced increases in nocturnal acidity and phosphoenolpyruvate carboxylase (PEPC) activity, suggesting photosynthetic flexibility. These results indicated that the regulation of carotenoids, NPQ, stomatal conductance and diel patterns of CO2 exchange presented the larger differences among studied plants at different altitudes and seem to be the protecting mechanisms controlling the photosynthetic performance of M. vulgare plants under drought conditions.

    To verify the possible involvement of lipids and several other compounds including hydrogen peroxide (H(2)O(2)) and glyceraldehyde-3-phosphate dehydrogenase (G3PDH) in the response of Hordeum vulgare to early potassium deprivation, plants were grown in hydroponic conditions for 30d with a modified Hewitt nutrient solution containing 3mM K(+). They were then incubated for increasing periods of time ranging from 2 to 36h in the same medium deprived of K(+). In contrast to leaves, root K(+) concentration showed its greatest decrease after 6h of treatment. The main lipids of the control barley roots were phospholipids (PL), representing more than 50% of the total lipids. PL did not change with treatment, whereas free sterols (FS) decreased following K(+) deprivation, showing a reduction of approximately 17% after 36h. With respect to the individual PL, 30h K(+) deprivation led to a reduction in phosphatidylcholine (PC), phosphatidylserine (PS), and phosphatidylinositol (PI) levels, whereas phosphatidylglycerol (PG), phosphatidylethanolamine (PE), and phosphatidic acid (PA) levels increased. The maximum PA accumulation and the highest phospholipase D (PLD) activation, estimated by an accumulation of phosphatidylbutanol (PtBut), were observed after 24h of K(+) starvation. At the root level, H(2)O(2) showed the maximum value after 6h of incubation in -K solution. In parallel, G3PDH activity reached its minimum. On the basis of a concomitant stimulation of PLD activity and, consequently, PA accumulation, enhancement of H(2)O(2) production, and inhibition of G3PDH activity, we suggest a possible involvement of these three compounds in an early response to K(+) deprivation.

  15. Sink-source proximity affecting photosynthate distributive pattern in barley (Hordeum Vulgare L.)

    International Nuclear Information System (INIS)

    Yielding ability of cereals is an interplay of source-sink capacities and is controlled presumably by physiological events at different growth stages. The translocation of 14C-sucrose from the flag leaf to the ears and other plant parts of the main tiller of barley (H. vulgare L. cv 292) were studied at its appearance (I), maturation (II) and senescence initiation (III) stages. At every stage, there was preferentially higher 14C-translocation from the flag leaf to the ears in comparison to other plant parts, indicating thereby the crucial role played by sink-source proximity in PHS'ate(photosynthate) Partg(partitioning). In order to ascertain such Partg behaviour of the different leaves on the main tiller at stage-II, the leaves starting basipetally, from flag to the fifth leaf, were labelled with 14C-sucrose and their relative translocation to the ears and roots were determined. There was a differential 14C-translocation to the sinks due to the change in the sink-source proximity, viz. >90% 14C were translocated to the ears from flag leaf, which declined to ≤5% only from the fifth leaf, the reverse being true for the roots. Further, spikelet's central grains preferentially accumulated more 14C-assimilates than the peripheral ones, probably due to being in close proximity to the unloading points. Thus, the distributive pattern of photoassimilates showed stage-specific quantitative changes and that the sink-source proximity played a crucial role in the PHS'ate Partg.

We have compared the effect of 10-week-long treatment with amlodipine or Marrubium water extract on systolic blood pressure (SBP), cardiovascular remodeling and vascular relaxation in spontaneously hypertensive rats (SHR). Both treatments produced similar decrease in SBP. Amlodipine treatment reduced left ventricle, aortic and mesenteric artery weight. Marrubium treatment had a significant antihypertrophic effect in aorta only. Relaxation to acetylcholine (ACh) of mesenteric artery was improved by Marrubium but not by amlodipine treatment. These results demonstrate that, in addition to its antihypertensive effect, Marrubium water extract improved the impaired endothelial function in SHR. PMID:15554450

    Response to a high salinity treatment of 300 mM NaCl was studied in a cultivated barley Hordeum vulgare Syrian cultivar Tadmor and in a halophytic wild barley H. marinum. Differential salinity tolerance of H. marinum and H. vulgare is underlied by qualitative and quantitative differences in proteins involved in a variety of biological processes. The major aim was to identify proteins underlying differential salinity tolerance between the two barley species. Analyses of plant water content, osmotic potential and accumulation of proline and dehydrin proteins under high salinity revealed a relatively higher water saturation deficit in H. marinum than in H. vulgare while H. vulgare had lower osmotic potential corresponding with high levels of proline and dehydrins. Analysis of proteins soluble upon boiling isolated from control and salt-treated crown tissues revealed similarities as well as differences between H. marinum and H. vulgare. The similar salinity responses of both barley species lie in enhanced levels of stress-protective proteins such as defense-related proteins from late-embryogenesis abundant family, several chaperones from heat shock protein family, and others such as GrpE. However, there have also been found significant differences between H. marinum and H. vulgare salinity response indicating an active stress acclimation in H. marinum while stress damage in H. vulgare. An active acclimation to high salinity in H. marinum is underlined by enhanced levels of several stress-responsive transcription factors from basic leucine zipper and nascent polypeptide-associated complex families. In salt-treated H. marinum, enhanced levels of proteins involved in energy metabolism such as glycolysis, ATP metabolism, and photosynthesis-related proteins indicate an active acclimation to enhanced energy requirements during an establishment of novel plant homeostasis. In contrast, changes at proteome level in salt-treated H. vulgare indicate plant tissue damage as

    Marrubium vulgare and Withania somnifera are used in folk medicine of several countries. Many researches showed that they are used for the treatment of variety of diseases due to their antioxidant effects. The present aim of this study was to evaluate the antihepatotoxic and antioxidant activities of the both extracts against carbon tetrachloride (CCl4)-induced hepatic damage in rats. Both extracts were given orally in a dose of 500 mg/kg/day for 4 weeks along with CCl4 started at the 7th week of induction of hepatotoxicity. The antihepatotoxic activity was assessed by measuring aspartate transaminase (AST), alanine transaminase (ALT), lactate dehydrogenase (LDH), alkaline phosphatase (ALP), glutathione peroxidase (GPx), glutathione reductase (GR), glutathione-S-transferase (GST), reduced glutathione (GSH), tissue content and malondialdehyde (MDA) as well as histopathological examination. Both extracts showed a significant antihepatotoxic effect by reducing significantly the levels of AST, ALT and LDH. However, ALP levels were decreased non-significantly. Regarding the antioxidant activity, they exhibited significant effects by increasing the GPx, GR and GST activities with increased GSH tissue contents and decreased production of MDA level. Furthermore, both extracts alleviated histopathological changes in rats' liver treated with CCl4. M. vulgare and W. somnifera protect the rats' liver against CCl4-induced hepatotoxicity. This effect may be attributed, at least in part, to the antioxidant activities of these extracts. PMID:24825994

    The objective of the present study was to elucidate the beneficial properties of aqueous extracts of Marrubium vulgare (AEM) towards cardiovascular disease by protecting human-LDL against lipid peroxidation and promoting HDL-mediated cholesterol efflux. Human-LDL were oxidised by incubation with CuSO(4) in the presence of increased concentrations of AEM (0-100 microg/ml). LDL lipid peroxidation was evaluated by conjugated diene formation, vitamin E disappearance as well as LDL-electrophoretic mobility. HDL-mediated cholesterol efflux assay was carried out in human THP-1 macrophages. Incubation of LDL with AEM significantly prolonged the lag phase (P=0.014), lowered the progression rate of lipid peroxidation (P=0.004), reduced the disappearance of vitamin E and the electrophoretic mobility in a dose-dependent manner. Also, incubation of HDL with AEM significantly increased HDL-mediated cholesterol efflux from THP-1 macrophages implicating an independent ATP binding cassette A1 (ABCA1) pathways. Our findings suggest that M. vulgare provides a source of natural antioxidants, which inhibit LDL oxidation and enhance reverse cholesterol transport and thus can prevent cardiovascular diseases development. These antioxidant properties increase the anti-atherogenic potential of HDL. PMID:17045616

    Cecropia obtusifolia and Marrubium vulgare have been widely used in Mexican traditional medicine for the control of type 2 diabetes. In order to evaluate the clinical effect produced by the aqueous extract from these species on type 2 non-controlled diabetes mellitus, a total of 43 outpatients were included. Based on the European NIDDM (policy group) criteria, only patients with poor response to the conventional treatment were selected. All patients maintained their medical treatment and also received a prepared infusion of the dry leaves of the plant treatment for 21 days. In a double-blind manner, the patients were randomly grouped as follows: 22 patients were treated with C. obtusifolia and 21 with M. vulgare. The fasting blood glucose values were reduced by 15.25% on patients treated with C. obtusifolia, while cholesterol and triglycerides were decreased by 14.62% and 42.0%, respectively (ANOVA pvulgare, the plasma glucose level was reduced by 0.64% and cholesterol and triglycerides by 4.16% and 5.78%, respectively. When the results were compared between groups, significant differences in glucose and cholesterol diminution were found. The obtained results showed that the infusion prepared with the leaves of C. obtusifolia (containing 2.99+/-0.14mg of chlorogenic acid/g of dried plant) produced beneficial effects on carbohydrate and lipid metabolisms when it was administered as an adjunct on patients with type 2 diabetes with poor response to conventional medical treatment.

    The effect of an arbuscular mycorrhizal fungi (AMF) consortium conformed by (Glomus intraradices, Glomus albidum, Glomus diaphanum, and Glomus claroideum) on plant growth and absorption of Pb, Fe, Na, Ca, and (32)P in barley (Hordeum vulgare L.) and sunflower (Helianthus annuus L.) plants was evaluated. AMF-plants and controls were grown in a substrate amended with powdered Pb slag at proportions of 0, 10, 20, and 30% v/v equivalent to total Pb contents of 117; 5,337; 13,659, and 19,913 mg Pb kg(-1) substrate, respectively. Mycorrhizal root colonization values were 70, 94, 98, and 90%, for barley and 91, 97, 95, and 97%, for sunflower. AMF inoculum had positive repercussions on plant development of both crops. Mycorrhizal barley absorbed more Pb (40.4 mg Pb kg(-1)) shoot dry weight than non-colonized controls (26.5 mg Pb kg(-1)) when treated with a high Pb slag dosage. This increase was higher in roots than shoots (650.0 and 511.5 mg Pb kg(-1) root dry weight, respectively). A similar pattern was found in sunflower. Plants with AMF absorbed equal or lower amounts of Fe, Na and Ca than controls. H. vulgare absorbed more total P (1.0%) than H. annuus (0.9%). The arbuscular mycorrizal consortium enhanced Pb extraction by plants. PMID:25495930

    Full Text Available Morphometrical indexes, and spectrophotometrically measured protein and glutathione (GSH, GSSG contents and activity of peroxidase (POD, EC 1.11.1.7, glutathione-reductase (GR, EC 1.6.4.2 and glutathione S-transferase (GST, EС 2.5.1.18 were examined in Hordeum vulgare L. seedlings after 0.01 and 0.1 mg/l AgNPs treatment during 24 h. We tested the hypothesis that the action of nanoparticles has a stressful effect on the physiological and biochemical processes of seedlings. Growth of roots was inhibited and fresh weight decreased by 29% and 21% under low and high concentrations respectively. Conversely, leaf growth was intensified, and leaf length (16% and 18% and fresh weight (35% and 44% increased at low and high concentrations respectively. POD activity in roots increased by 26% and 7%, and decreased in leaves to 57% and 81% of control at low and high concentrations respectively. GSH content changed insignificantly, but GSSG content increased in roots (2 and 2.5-fold and in leaves (13% and 30% at both AgNPs concentrations. GSH/GSSG-ratio decreased in roots (1.9 and 2.6-fold and in leaves (1.1 and 1.3-fold at low and high concentrations respectively. GR activity decreased at a concentration of 0.01 mg/l (7% in roots and 17% in leaves respectively and increased at 0.1 mg/l (52% in roots and 6% in leaves. GST activity increased in leaves (52% and 78% at low and high concentrations but decreased by 17% in roots under high concentration of nanosilver. Thus, the action of AgNPs on barley seedlings had a dose-dependent and organ-specific character. The various directions of changes in growth, metabolic processes and activity of antioxidant defense systems appear to be a stress response of barley seedlings to the impact of AgNPs, which underlines the necessity of detailed study of plant intracellular processes exposed to the action of nanomaterial.

    The 131J- ion applied as KJ solution to lanolin ring on the leaf moved quickly to other parts of the leaf, however, it was transported to the stem and axillary bud in small amount. The 131J- ion from potassium iodide was absorbed very fast by privet (Ligustrum vulgare L.). By 45 min after treatment about half of the applied ion was absorbed. This result was also confirmed in field experiments with non labelled KJ with privet and with SpiraeaXbumalda cv. Froebelii during 2 year experiments. In the conditions of high air humidity (95% r.h.) much more K131J was absorbed than at low air humidity (50% r.h.) at the same temperature (230). Also at a relatively high temperature (230) the uptake was more intensive than at a low temperature (40), at the same air humidity (95% r.h.). (author)

If so, on the one hand, the common names are refused to fulfill the classification objectives. But, on the other hand, the symbolic meanings and functions which are rooted to the popular speech will be thrown over. Names are keys of a sign system or of a determined cosmovision.

The major components of Origanum vulgare L. essential oil (OVEO were limonene, caryophyllene oxide, α-ionone, germacrene– D, γ- terpinene, β- pinene and terpinene-4-ol. For evaluating antifungal activities of CZEO and OVEO, A. flavus PTCC: 5006, was inoculated in Sabouraud Dextrose Broth (SDB and tomato paste, then 0, 50, 100, 200, 300, 400, 500 and 600 ppm of essential oils were added to each sample and incubated at 25±0.5oC for 30 and 60 days, respectively. The antifungal activity was measured by Agar Dilution method. The EOs at all tested concentrations had inhibitory effect against A. flavus growth. 200 ppm of CZEO and 500 ppm of OVEO completely inhibited A. flavus growth in culture media, while in tomato paste 300 ppm of CZEO and 200 ppm of OVEO had the same effect. Test panel evaluations were carried out in tomato ketchup base and samples with 100 and 200 ppm CZEO were accepted by panelists. The results may suggest the potential replacement of antifungal chemicals by CZEO as natural inhibitor to control A. flavus growth in tomato paste.

    Full Text Available Background: Marrubium vulgare Lamiaceae, known as white horehound, is frequently used in folk medicine to treat many illnesses from ancient times. Aims: The present study is conducted to evaluate the anti-inflammatory activity of hydromethanolic extract of the aerial part of M. vulgare. Materials and Methods: The oxygen consumption and the production of superoxide anions, by rat pleural polymorphonuclear leukocytes stimulated by opsonized zymosan, were performed. PMNs were collected after induction of an acute inflammatory reaction by injection, in the rat pleural cavity, of suspension of calcium pyrophosphate crystals. Plant extract was tested at a concentration range 10-100 mg/ml and 100-400 mg/kg/day for in vitro and in vivo assays respectively. Statistical analysis: All values are expressed as mean ΁ standard error. The significance of differences between control and treated samples in vitro was analysed using the Student′s t-test. For in vivo studies, data were analysed using one-way analysis of variance. Differences with P ≤ 0.05 were considered to be statistically significant. Results: Hydromethanolic extract of M. vulgare showed, in vitro a significant anti-inflammatory effect in a dose-dependent manner. In vivo, only the high amounts of the plant extract (300 and 400 mg/kg/day exhibited a significant anti-inflammatory effect. The plant extract contains a high amount of polyphenols. Conclusion: Hydromethanolic extract of M. vulgare had an anti-inflammatory effect, which corroborates the usefulness of this plant in the treatment of inflammatory disorders.

    Full Text Available Heavy metals and other toxic elements in the environment, mainly located in soil and groundwater, have a significant effect on plant and its productivity that has a huge attention in recent years. Accumulation of heavy metals in soil cause toxicity to plants, and contaminate the food chain. The industrial areas, as well as developing countries have been contaminated with high concentration of heavy metals. Main sources of contamination are mining and other industrial processes, as well as military and or lanfills, sludge dumps or waste disposal sites. The heavy metals are very dangerous to environment and pose serious danger to public health by entering throught the food chain or into drinking water. Phytoextraction is one way how to remove the contaminants from soil by plants. Phytoextraction of heavy metals is a technology that has been studied for several years. It is more ecological and cheaper way how to clean our environment.Several plant species are known becauce they hyperaccumulate a high contents of metals from the soil. The accumulators are mainly herbaceous species, crops and nowadays angiosperm trees with a high growth such as poplars or willows. We have focused on the determination of some morphological (lenght and weight of roots and biomass and physiological (contents of dry mass and number of lief stomata characteristics and the determination of the bioaccumulation factor and the translocation factor of cadmium by spring barley (Hordeum vulgare L..

    2005-01-01

    106 accessions of Tibetan wild barley, including 50 accessions of the two-rowed wild barley Hordeum vulgare ssp. spontaneum(HS), 27 accessions of the six-rowed bottle-shaped wild barley H. lagunculiforme(HL) and 29 accessions of the six-rowed wild barley H. agriocrithon(HA) that separately represent different agrigeographical regions of Tibet, were used to study the genetic diversity and genetic differentiation using SSR markers selected from seven barley linkage groups. 229 allelic variants were identified with an average of 7.6 alleles/locus. The average of total number of alleles per locus in HA(6.4) is much higher than that in HS(3.9) and HL(3.4). The genetic diversity and its standard deviation among the three subspecies were in the order of HS>HL>HA. Very significant genetic differentiation was observed among the three subspecies of wild barley. Comparisons of the results from this and previous studies showed a strong Oriental-Occidental differentiation of barley, and that Shannan region of Tibet might be the center of origin of the Tibetan two-rowed wild barley, thus supporting not only the hypothesis of a mono-phyletic origin of cultivated barley but also the proposition that the Tibetan two-rowed wild barley as ultimate progenitor of Chinese cultivated barley.

    Plant essential oils (EOs) can potentially replace synthetic fungicides in the management of postharvest fruit and vegetable diseases. The aim of this study was to evaluate in vitro and in vivo effectiveness of thymol, carvacrol, linalool, and trans-caryophyllene, single constituents of the EO of Origanum vulgare L. ssp. hirtum against Monilinia laxa, M. fructigena, and M. fructicola, which are important phytopathogens and causal agents of brown rot of pome and stone fruits in pre- and postharvest. Moreover, the possible phytotoxic activity of these constituents was assessed and their minimum inhibitory concentration (MIC) was determined. In vitro experiment indicated that thymol and carvacrol possess the highest antifungal activity. Results of in vivo trials confirmed the strong efficacy of thymol and carvacrol against brown rot of peach fruits. The thymol MIC resulted to be 0.16 μg/μL against M. laxa and M. fructigena and 0.12 μg/μL against M. fructicola, whereas for carvacrol they were 0.02 μg/μL against the first two Monilinia species and 0.03 μg/μL against the third. Results of this study indicated that thymol and carvacrol could be used after suitable formulation for controlling postharvest fruit diseases caused by the three studied Monilinia species.

    Full Text Available This study assessed the occurrence of an enhancing inhibitory effect of the combined application of Origanum vulgare L. essential oil and lactic acid against Staphylococcus aureus by the determination of Fractional Inhibitory Concentration (FIC index and cell viability in meat broth and meat model. Minimum Inhibitory Concentration (MIC and Minimum Bactericidal Concentration (MBC of the oil was 0.6 and 1.25 µL.mL-1, respectively. Lactic acid showed MIC and MBC of 2.5 and 5µL.mL-1, respectively. FIC indices of the combined application of the oil and lactic acid were 0.5 showing a synergic interaction. The essential oil and lactic acid showed similar (p>0.05 anti-S. aureus effect in meat broth over 96 h of exposure. Treatment with essential oil or lactic acid presented a smaller anti-staphylococcal effect in meat in comparison to meat broth. No significant difference (p>0.05 was found for the microbial counts in meat treated with each antimicrobial alone or in mixture. These results could arise as an interesting approach for the improvement of food preservation using more natural procedures, considering the current demand of consumer and sensory quality of foods.

    1. The objective of the present study was to investigate the mechanism of the relaxant activity of marrubenol, a diterpenoid extracted from Marrubium vulgare. In rat aorta, marrubenol was a more potent inhibitor of the contraction evoked by 100 mM KCl (IC50: 11.8+/-0.3 microM, maximum relaxation: 93+/-0.6%) than of the contraction evoked by noradrenaline (maximum relaxation: 30+/-1.5%). 2. In fura-2-loaded aorta, marrubenol simultaneously inhibited the Ca2+ signal and the contraction evoked by 100 mM KCl, and decreased the quenching rate of fura-2 fluorescence by Mn2+. 3. Patch-clamp data obtained in aortic smooth muscle cells (A7r5) indicated that marrubenol inhibited Ba2+ inward current in a voltage-dependent manner (KD: 8+/-2 and 40+/-6 microM at holding potentials of -50 and -100 mV, respectively). 4. These results showed that marrubenol inhibits smooth muscle contraction by blocking L-type calcium channels. PMID:14597602

    Full Text Available Purpose: The study is aimed at finding new antibiotic therapy for aquaculture due to potential of bacteria to develop resistance to the existing therapies. Use of large quantities of synthetic antibiotics in aquaculture thus has the potential to be detrimental to fish health, to the environment and wildlife and to human health. Methods: Antimicrobial potential of volatile oil and fractions of chloroform extract of Oreganum vulgare was evaluated alone and in the presence of standard antimicrobials against common fish pathogens by disc-diffusion, agar well assay and two fold microdilution method by nanodrop spectrophotometric method. Results: The best results were represented by volatile oil followed by phenolic fraction by disc-diffusion, agar well and microdilution assays (Minimum inhibitory concentration. By the interaction studies, it was observed that the volatile oil and phenolic fraction were able to inhibit the pathogens at very low concentration compared to standard drugs. The fractional inhibitory concentration index (FICI was calculated and volatile oil and phenolic fractions were found to be synergistic against Pseudomonas fluorescens and Candida albicans. Conclusion: The experimental data suggests the use of volatile oil and phenolic fraction in combination with standard antimicrobials to maintain healthy aquaculture with lesser adverse effects as compared to synthetic antibiotic therapy.

    Full Text Available Barley stripe mosaic virus (BSMV is an established and extensively used virus-induced gene silencing (VIGS vector for gene function analysis in monocots. However, the phenotypes generated by targeted gene silencing may be affected or masked by symptoms of BSMV infection. To better understand the potential effects of BSMV-VIGS in hulless barley (Hordeum vulgare var. nudum, the accumulation pattern of BSMV and its impacts on vegetative growth and water status were investigated. The results indicated that the vegetative growth of infected plants was significantly and continuously impacted by BSMV from 10 to 40 days post inoculation (dpi. When the accumulation of BSMV was extremely high (7 to 11 dpi, infected plants displayed twisted leaf tips with an increased water lose rate (WLR and decreased water content (WC. Virus accumulation declined and stabilized after 25 dpi, at this stage, the WLR and WC were unaffected in the infected plants. The efficiency of VIGS was tested by the silencing of Phytoene desaturase (PDS. RT-qPCR indicated that BSMV-VIGS can be sustained with good efficiency for up to 40 dpi under an altered condition with lower temperature (22 ±1°C and higher relative humidity (70 ±10%. It was concluded that 25 to 40 dpi was the appropriate time zone for drought-related gene analysis by BSMV-VIGS under such condition.

    Hydroponic experiments were conducted in a growth chamber and changes in the hydraulic conductivity of sorghum (Sorghum vulgare Pers.) roots (Lpr) at the three-leaf stage were measured using the pressure chamber method. Water deficiency was imposed with polyethylene glycol (PEG) 6000 and the phosphorus (P) levels were controlled by complete Hoagland solution with and without P nutrient. The objective of this study was to investigate the effect of P nutrition on root Lpr under water deficiency. The results showed that the Lpr in P deficiency treatments decreased markedly, but the Lpr recovered to the same value as that of control when sufficient P was supplied for 4-24 h. Water deficiency decreased Lpr, but the hydraulic conductivity of the roots with sufficient P supply was still higher than that of plants without P supply. When resuming water supply, the Lpr of the water-deficient plants under P supply recovered faster than that of plants without P supply, which indicates that plants with sufficient P nutrient are more drought tolerant and have a greater ability to recover after drought. The treatment of HgCl2 indicated that P nutrient could regulate the Lpr by affecting the activity and the expression levels of aquaporins.

    Consumers' concerns about the environment and health have led to the development of new food packaging materials avoiding petroleum-based matrices and synthetic additives. The present study has developed polylactic acid (PLA) films containing different concentrations of essential oil from Origanum vulgare L. virens (OEO). The effectiveness of this new active packaging was checked for use in ready-to-eat salads. A plasticising effect was observed when OEO was incorporated in PLA films. The rest of the mechanical and physical properties of developed films did not show much change when OEO was included in the film. An antioxidant effect was recorded only for films containing the highest percentages of the active agent (5% and 10%). In addition, films exhibited in vitro antibacterial activity against Staphylococcus aureus, Yersinia enterocolitica, Listeria monocytogenes, Enterococcus faecalis and Staphylococcus carnosus. Moreover, in ready-to-eat salads, antimicrobial activity was only observed against yeast and moulds, where 5% and 10% of OEO was the most effective. PMID:27455176

    Three different isoforms of invertases have been detected in the developing internodes of barley (Hordeum vulgare). Based on substrate specificities, the isoforms have been identified to be invertases (beta-fructosidases EC 3.2.1.26). The soluble (cytosolic) invertase isoform can be purified to apparent homogeneity by diethylaminoethyl cellulose, Concanavalin-A Sepharose, organo-mercurial Sepharose, and Sephacryl S-300 chromatography. A bound (cell wall) invertase isoform can be released by 1 molar salt and purified further by the same procedures as above except omitting the organo-mercurial Sepharose affinity chromatography step. A third isoform of invertase, which is apparently tightly associated with the cell wall, cannot be isolated yet. The soluble and bound invertase isoforms were purified by factors of 60- and 7-fold, respectively. The native enzymes have an apparent molecular weight of 120 kilodaltons as estimated by gel filtration. They have been identified to be dimers under denaturing and nondenaturing conditions. The soluble enzyme has a pH optimum of 5.5, Km of 12 millimolar, and a Vmax of 80 micromole per minute per milligram of protein compared with cell wall isozyme which has a pH optimum of 4.5, Km of millimolar, and a Vmax of 9 micromole per minute per milligram of protein.

    The tucuma (Astrocaryum vulgare Mart.) is a native fruit of Amazonia, occurring mainly in the state of Para, but also found in the Brazilian northeast states and in the Brazilian central-western states. The tucuma is considered an excellent source of carotenoids with a very high concentration of {beta}-carotene, which is a precursor of vitamin A. In addition to carotenoids it is an important source of vitamin B2 (riboflavin) in fruits. This study aimed to analyze the effects of gamma radiation on the nutritional value of tucuma. The fruits were irradiated at doses of 0.5, 1.0 and 2.0 kGy irradiator with a source of cesium 137. The carotenoids were determined by spectrophotometry. The analysis of {alpha} and {beta}-carotene, thiamine, riboflavin were carried out by high performance liquid chromatography (HPLC). The {beta}-carotene accounts for 80% of total carotenoids in tucuma, and with a dose of 2 kGy, it showed the highest reduction of {beta}-carotene, about 7.5% in relation to the control. The tucuma fruit showed high levels of riboflavin from 0.183 to 0.222 {mu}g 100 g{sup -1}, and maintained stability after the gamma radiation process. However, it had low levels of thiamine from 0.050 to 0.033 {mu}g 100 g{sup -1}, and irradiated at a dose of 2 kGy showed significant reductions of thiamine, about 34% in relation to the control.

    This study investigated the in vivo antimicrobial activity of the essential oils of Origanum vulgare and Mentha piperita both singly, associated and in combination with immunotherapy to treat experimental pythiosis. The disease was reproduced in 18 rabbits divided into six groups (n=3): group 1, control; group 2, treated with essential oil of Mentha piperita; group 3, treated with essential oil of Origanum vulgare; group 4, treated with commercial immunotherapic; group 5, treated with a association of oils of M. piperita and O. vulgare and group 6, treated with a combination of both oils plus immunotherapy. Essential oils were added in a topical cream base formula, and lesions were treated daily for 45 days. The animals in groups 4 and 6 received a dose of immunotherapeutic agent every 14 days. The results revealed that the evolution of lesions in groups 5 and 6 did not differ from one another but differed from the other groups. The lesions of group 5 increased 3.16 times every measurement, while those of group 6 increased 1.83 times, indicating that the smallest growth of the lesions occurred when the combination of therapies were used. A rabbit from group 5 showed clinical cure at day 20 of treatment. This research is the pioneer in the treatment of experimental pythiosis using essential oils from medicinal plants and a combination of therapies. This study demonstrated that the use of essential oils can be a viable alternative treatment to cutaneous pythiosis, particularly when used in association or combination with immunotherapy.

    Highlights: •6-ODA, a rare fatty acid with a triple bond, was identified from Marrubium vulgare. •6-ODA was synthesized from petroselinic acid as a starting material. •6-ODA stimulated lipid accumulation in HSC-T6 and 3T3-L1 cells. •The first report of a fatty acid with a triple bond functioning as a PPARγ agonist. •This study sheds light on novel functions of a fatty acid with a triple bond. -- Abstract: 6-Octadecynoic acid (6-ODA), a fatty acid with a triple bond, was identified in the methanol extract of Marrubium vulgare L. as an agonist of peroxisome proliferator-activated receptor γ (PPARγ). Fibrogenesis caused by hepatic stellate cells is inhibited by PPARγ whose ligands are clinically used for the treatment of diabetes. Plant extracts of Marrubium vulgare L., were screened for activity to inhibit fibrosis in the hepatic stellate cell line HSC-T6 using Oil Red-O staining, which detects lipids that typically accumulate in quiescent hepatic stellate cells. A methanol extract with activity to stimulate accumulation of lipids was obtained. This extract was found to have PPARγ agonist activity using a luciferase reporter assay. After purification using several chromatographic methods, 6-ODA, a fatty acid with a triple bond, was identified as a candidate of PPARγ agonist. Synthesized 6-ODA and its derivative 9-octadecynoic acid (9-ODA), which both have a triple bond but in different positions, activated PPARγ in a luciferase reporter assay and increased lipid accumulation in 3T3-L1 adipocytes in a PPARγ-dependent manner. There is little information about the biological activity of fatty acids with a triple bond, and to our knowledge, this is the first report that 6-ODA and 9-ODA function as PPARγ agonists.

    Mosquito-borne diseases represent a deadly threat for millions of people worldwide. However, the use of synthetic insecticides to control Culicidae may lead to resistance, high operational costs and adverse non-target effects. Nowadays, plant-borne mosquitocides may serve as suitable alternative in the fight against mosquito vectors. In this study, the mosquito larvicidal activity of Origanum vulgare (Lamiaceae) leaf essential oil (EO) and its major chemical constituents was evaluated against the malaria vectors Anopheles stephensi and An. subpictus, the filariasis vector Culex quinquefasciatus and the Japanese encephalitis vector Cx. tritaeniorhynchus. The chemical composition of the EO was analyzed by gas chromatography-mass spectroscopy. GC-MS revealed that the essential oil of O. vulgare contained 17 compounds. The major chemical components were carvacrol (38.30%) and terpinen-4-ol (28.70%). EO had a significant toxic effect against early third-stage larvae of An. stephensi, An. subpictus, Cx. quinquefasciatus and Cx. tritaeniorhynchus, with LC50 values of 67.00, 74.14, 80.35 and 84.93 μg/ml. The two major constituents extracted from the O. vulgare EO were tested individually for acute toxicity against larvae of the four mosquito vectors. Carvacrol and terpinen-4-ol appeared to be most effective against An. stephensi (LC50=21.15 and 43.27 μg/ml, respectively) followed by An. subpictus (LC50=24.06 and 47.73 μg/ml), Cx. quinquefasciatus (LC50=26.08 and 52.19 μg/ml) and Cx. tritaeniorhynchus (LC50=27.95 and 54.87 μg/ml). Overall, this research adds knowledge to develop newer and safer natural larvicides against malaria, filariasis and Japanese encephalitis mosquito vectors. PMID:26850541

    Full Text Available The aim of this study was to assess the effects of a fungicide (copper hydroxide with 50% metallic copper (Co and of an insecticide (bifenthrin 100 g/l (B on spore germination and gametophyte development in the fern species Athyrium filix-femina (L. Schott. and Polypodium vulgare L. The experimental variants were: V1Co: 0.1 gr fungicide/100 ml Knop solution, V2Co: 0.2 gr fungicide/100 ml Knop solution, V3Co: 3 gr fungicide/100 ml Knop solution, V1B: 0.01 ml insecticide/100 ml Knop solution, V2B: 0.02 ml insecticide/100 ml Knop solution, V3B: 0.04 ml insecticide/100 ml Knop solution and Control (C: 100 ml Knop solution. Co inhibited spore germination in all the experimental variants tested on the species Athyrium filix-femina. In the V3Co variant, after 24 days, no spore germinated. B also inhibited spore germination in all the experimental variants. In Polypodium vulgare, Co significantly inhibited spore germination. In the experimental variants containing B, only in the V3B variant the germination is significantly inhibited. Calculations showed a significant negative correlation between the germination percentage and the concentration of pesticides. The fungicide also affected gametophyte differentiation, which happened much more slowly in both species. The rhizoids of the gametophytes of Polypodium vulgare showed modifications in their differentiation and morphology that could also be related to alterations in their biochemical composition. The experimental variants with the highest concentration of insecticide resulted in the differentiation of abnormal gametophytes growing in a tridimensional cellular mass with callus morphology. The responses of plants to the induced stress produced during the testing period may be used as biomarkers of environmental pollution caused by pesticides.

    Full Text Available Background and purpose: During recent years, nitric oxide (NO has been considered as a molecule involved in migraine headaches. This free radical involves in initiation of migraine headaches via NO/cGMP signaling pathway and vascular relaxation specially big intracranial arteries. Therefore, we studied the effects of aqueous extract of Origanum vulgare and Melilotus officinalis prescribed in migraine treatment in traditional & modern medicine, on NO level in cultured endothelial cells.Materials and Methods: Each crude herb (25g was mixed with 200 ml distilled water. End extract obtained after filtering and drying. Endothelial cells propagated in DMEM medium containing 10% FCS and 1-2% penicillin-streptomycin. The nitrite concentration was measured as an indicator of nitric oxide production according to the Griess reaction and with ELISA in 540 nm.Results: Concentrations of 100, 200 and 400 g/ml of Origanum vulgare, reduced NO levels compared with control to 13.1 % (p<0.05, 25.8% (p<0.01 and 33.9% (p<0.001 respectively. However, despite our expectation melilotus officinalis increased NO level. The concentrations of 100, 200 and 400 g/ml of the herb, increased NO levels to 12.7 (p<0.05, 36.5% (p<0.001 & 72.9% (p<0.001 respectively.Conclusion: We concluded that aqueous extract of Origanum vulgare probably decreases migraine headaches by reducing NO and aqueous extract of Melilotus officinalis does not act through this mechanism.

    Highlights: •6-ODA, a rare fatty acid with a triple bond, was identified from Marrubium vulgare. •6-ODA was synthesized from petroselinic acid as a starting material. •6-ODA stimulated lipid accumulation in HSC-T6 and 3T3-L1 cells. •The first report of a fatty acid with a triple bond functioning as a PPARγ agonist. •This study sheds light on novel functions of a fatty acid with a triple bond. -- Abstract: 6-Octadecynoic acid (6-ODA), a fatty acid with a triple bond, was identified in the methanol extract of Marrubium vulgare L. as an agonist of peroxisome proliferator-activated receptor γ (PPARγ). Fibrogenesis caused by hepatic stellate cells is inhibited by PPARγ whose ligands are clinically used for the treatment of diabetes. Plant extracts of Marrubium vulgare L., were screened for activity to inhibit fibrosis in the hepatic stellate cell line HSC-T6 using Oil Red-O staining, which detects lipids that typically accumulate in quiescent hepatic stellate cells. A methanol extract with activity to stimulate accumulation of lipids was obtained. This extract was found to have PPARγ agonist activity using a luciferase reporter assay. After purification using several chromatographic methods, 6-ODA, a fatty acid with a triple bond, was identified as a candidate of PPARγ agonist. Synthesized 6-ODA and its derivative 9-octadecynoic acid (9-ODA), which both have a triple bond but in different positions, activated PPARγ in a luciferase reporter assay and increased lipid accumulation in 3T3-L1 adipocytes in a PPARγ-dependent manner. There is little information about the biological activity of fatty acids with a triple bond, and to our knowledge, this is the first report that 6-ODA and 9-ODA function as PPARγ agonists

    Full Text Available The studies of Armadillidium vulgare as pest are virtually null worldwide. However under no-tillage systems this species has found an adequate environment for its development and it has become an important pest in some crops in Argentina. It has been shown that the composition of vegetables affects the isopods biology. Our hypothesis was that soybean leaf litter has high nutritive value which allows A. vulgare to grow faster, survive longer, and have higher fecundity favoring the population increase and turning it into a crop pest. Growth and survivorship of juveniles and adults, egg incubation period, offspring number per female and offspring mean body weight were determined in individuals fed with leaf litter of soybean, sunflower, wheat and pasture. The growth rate coefficient, k, in juveniles was higher for soybean, intermediate for pasture and lower for sunflower. Adult growth was faster under the soybean diet. Survivorship under soybean and pasture was longer than under sunflower and wheat in both juveniles and adults. The reproductive parameters were similar in all diets, food did not generate any change in the reproductive aspects of A. vulgare. Results of the present study represent a source of information about the A. vulgare biology under different diets of agricultural origin to establish the basis for Integrated Management of this species as pest. Under soybean litter provision A. vulgare found the best conditions for faster growth, longer survival and relatively higher fecundity. In fields with soybean as preceding crop or in systems with high frequency of soybean in the crop rotation a more abundant population of A. vulgare would be found as well as with larger individuals which could cause more damage to the following crop in the rotation.Los estudios sobre Armadillidium vulgare como plaga son virtualmente nulos a nivel mundial. Sin embargo, en los sistemas bajo siembra directa esta especie ha encontrado un ambiente adecuado para

  16. A flavonoid mutant of barley (Hordeum vulgare L.) exhibits increased sensitivity to UV-B radiation in the primary leaf

    International Nuclear Information System (INIS)

    The aim of the present investigation was to define the role of soluble flavonoids as UV-B protectants in the primary leaf of barley (Hordeum vulgare L.). For this purpose we used a mutant line (Ant 287) from the Carlsberg collection of proanthocyanidin-free barley containing only 7% of total extractable flavonoids in the primary leaf as compared to the mother variety (Hiege 550/75). Seven-day-old leaves from plants grown under high visible light with or without supplementary UV-B radiation were used for the determination of UV-B sensitivity. UV-B-induced changes were assessed from parameters of chlorophyll fluorescence of photosystem II, including initial and maximum fluorescence, apparent quantum yield, and photochemical and non-photochemical quenching. A quartz fibre-optic microprobe was used to evaluate the amount of potentially harmful UV-B (310 nm radiation) penetrating into the leaf as a direct consequence of flavonoid deficiency. Our data indicate an essential role of flavonoids in UV-B protection of barley primary leaves. In leaves of the mutant line grown under supplementary UV-B, an increase in 310nm radiation in the mesophyll and a strong decrease in the quantum yield of photosynthesis were observed as compared to the corresponding mother variety. Primary leaves of liege responded to supplementary UV-B radiation with a 30% increase in the major flavonoid saponarin and a 500% increase in the minor compound lutonarin. This is assumed to be an efficient protective response since no changes in variable chlorophyll fluorescence were apparent. In addition, a further reduction in UV-B penetration into the mesophyll was recorded in these leaves

    Full Text Available Abstract Background Chromosome pairing, recombination and DNA repair are essential processes during meiosis in sexually reproducing organisms. Investigating the bread wheat (Triticum aestivum L. Ph2 (Pairing homoeologous locus has identified numerous candidate genes that may have a role in controlling such processes, including TaMSH7, a plant specific member of the DNA mismatch repair family. Results Sequencing of the three MSH7 genes, located on the short arms of wheat chromosomes 3A, 3B and 3D, has revealed no significant sequence divergence at the amino acid level suggesting conservation of function across the homoeogroups. Functional analysis of MSH7 through the use of RNAi loss-of-function transgenics was undertaken in diploid barley (Hordeum vulgare L.. Quantitative real-time PCR revealed several T0 lines with reduced MSH7 expression. Positive segregants from two T1 lines studied in detail showed reduced MSH7 expression when compared to transformed controls and null segregants. Expression of MSH6, another member of the mismatch repair family which is most closely related to the MSH7 gene, was not significantly reduced in these lines. In both T1 lines, reduced seed set in positive segregants was observed. Conclusion Results presented here indicate, for the first time, a distinct functional role for MSH7 in vivo and show that expression of this gene is necessary for wild-type levels of fertility. These observations suggest that MSH7 has an important function during meiosis and as such remains a candidate for Ph2.

    The implications of metal nanoparticles (MeNPs) are still unknown for many food crops. The purpose of this study was to evaluate the effects of cerium oxide (nCeO2) and titanium oxide (nTiO2) nanoparticles in soil at 0, 500 and 1000 mg·kg−1 on the nutritional parameters of barley (Hordeum vulgare L.) kernels. Mineral nutrients, amylose, β-glucans, amino acid and crude protein (CP) concentrations were measured in kernels. Whole flour samples were analyzed by ICP-AES/MS, HPLC and Elemental CHNS Analyzer. Results showed that Ce and Ti accumulation under MeNPs treatments did not differ from the control treatment. However, nCeO2 and nTiO2 had an impact on composition and nutritional quality of barley kernels in contrasting ways. Both MeNPs left β-glucans unaffected but reduced amylose content by approximately 21%. Most amino acids and CP increased. Among amino acids, lysine followed by proline saw the largest increase (51% and 37%, respectively). Potassium and S were both negatively impacted by MeNPs, while B was only affected by 500 mg nCeO2·kg−1. On the contrary Zn and Mn concentrations were improved by 500 mg nTiO2·kg−1, and Ca by both nTiO2 treatments. Generally, our findings demonstrated that kernels are negatively affected by nCeO2 while nTiO2 can potentially have beneficial effects. However, both MeNPs have the potential to negatively impact malt and feed production. PMID:27294945

    Full Text Available Background Although second generation sequencing (2GS technologies allow re-sequencing of previously gold-standard-sequenced genomes, whole genome shotgun sequencing and de novo assembly of large and complex eukaryotic genomes is still difficult. Availability of a genome-wide physical map is therefore still a prerequisite for whole genome sequencing for genomes like barley. To start such an endeavor, large insert genomic libraries, i.e. Bacterial Artificial Chromosome (BAC libraries, which are unbiased and representing deep haploid genome coverage, need to be ready in place. Result Five new BAC libraries were constructed for barley (Hordeum vulgare L. cultivar Morex. These libraries were constructed in different cloning sites (HindIII, EcoRI, MboI and BstXI of the respective vectors. In order to enhance unbiased genome representation and to minimize the number of gaps between BAC contigs, which are often due to uneven distribution of restriction sites, a mechanically sheared library was also generated. The new BAC libraries were fully characterized in depth by scrutinizing the major quality parameters such as average insert size, degree of contamination (plate wide, neighboring, and chloroplast, empty wells and off-scale clones (clones with 250 fragments. Additionally a set of gene-based probes were hybridized to high density BAC filters and showed that genome coverage of each library is between 2.4 and 6.6 X. Conclusion BAC libraries representing >20 haploid genomes are available as a new resource to the barley research community. Systematic utilization of these libraries in high-throughput BAC fingerprinting should allow developing a genome-wide physical map for the barley genome, which will be instrumental for map-based gene isolation and genome sequencing.

    Full Text Available Abstract Background Among the cereal crops, barley is the species with the greatest adaptability to a wide range of environments. To determine the level and structure of genetic diversity in barley (Hordeum vulgare L. landraces from the central highlands of Ethiopia, we have examined the molecular variation at seven nuclear microsatellite loci. Results A total of 106 landrace populations were sampled in the two growing seasons (Meher and Belg; the long and short rainy seasons, respectively, across three districts (Ankober, Mojanawadera and Tarmaber, and within each district along an altitudinal gradient (from 1,798 to 3,324 m a.s.l. Overall, although significant, the divergence (e.g. FST is very low between seasons and geographical districts, while it is high between different classes of altitude. Selection for adaptation to different altitudes appears to be the main factor that has determined the observed clinal variation, along with population-size effects. Conclusions Our data show that barley landraces from Ethiopia are constituted by highly variable local populations (farmer's fields that have large within-population diversity. These landraces are also shown to be locally adapted, with the major driving force that has shaped their population structure being consistent with selection for adaptation along an altitudinal gradient. Overall, our study highlights the potential of such landraces as a source of useful alleles. Furthermore, these landraces also represent an ideal system to study the processes of adaptation and for the identification of genes and genomic regions that have adaptive roles in crop species.

    A method for analyzing honey samples was developed that enabled the simultaneous detection and identification of pyrrolizidine alkaloids and their N-oxides. Honey samples were treated with methanol or dilute sulfuric acid and then centrifuged to remove insoluble material. Subsequent strong cation exchange, solid-phase extraction of the supernatant provided a fraction that was analyzed for the presence of pyrrolizidine alkaloids and their N-oxides using high-pressure liquid chromatography coupled to electrospray ionization mass spectrometry. The procedure was validated using extracts of Echium plantagineum and authenticated standards of pyrrolizidine alkaloids and their N-oxides from other plant sources. Of several variations of the solid-phase extraction method assessed in this study, the best combination for generic use involved the dilution of honey with 0.05 M sulfuric acid and the subsequent application of the centrifuged solution to solid-phase extraction columns at the rate of a maximum of 10 g of honey per solid-phase extraction column. The method was applied to the analysis of nine floral honeys, five of which were attributed by the apiarist to Echium vulgare. Seven of the honey samples were positive for pyrrolizidine alkaloids and N-oxides characteristic of E. vulgare. PMID:15769110

    Full Text Available In order to determine the performance of barley under drought stress conditions and screening quantitative indices of drought tolerance, twelve barley (Hordeum vulgare L. cultivars were tested in a split-plot arranged in a randomized complete blocks design with three replications under irrigated and post-anthesis water deficiency conditions. This study was carried out in the field research of campus of agriculture and natural resources, Razi university, Kermanshah state in the west of Iran during 2010-2011. The results showed that post anthesis water deficiency caused 22, 18.3, 5.9, 5.5 and 21.9 percent reduction in grain yield, biomass, thousand grain weight, number of grain per spike and number of spike per m2 in average respectively, but had no significant effect on harvest index. Mean comparisons showed that Nosrat cultivar with 838 g m-2 and Afzal cultivar with 392 g m-2, respectively had the highest and the lowest grain yield under non-stress condition. Under water stress environment Nosrat and Karoun cultivars with 696 and 656 g m-2 and also, Aras and Sahra cultivars with 322 and 327 g m-2, respectively had the highest and the lowest grain yield. The estimates of stress tolerance attributes indicated that the identification of drought-tolerant genotypes based on a single criterion was contradictory. For example, according to STI, GMP and MP cultivars Nosrat, Karoun and Sararud were the most, whereas Aras and Afzal cultivars the least relative tolerant genotypes. As to YI cultivars Nosrat, Karoun and Sararud were the most and Aras, Sahra and Afzal the least relative tolerant genotypes. According to YSI, SSPI, RDI and ATI indices selected the Sararud and Zarjo cultivars as the most relatively tolerant genotypes. DI selected the cultivars Sararud, Nosrat and Karoun as the best, while the cultivars Sahra, Aras and Reihan as the the worst relatively tolerant genotypes. Grain yield in stress condition was significantly and positively correlated

    Plant Growth Promoting Bacteria (PGPB) are considered a promising approach to replace the conventional agricultural practices, since they have been shown to affect plant nutrient-acquisition processes by influencing nutrient availability in the rhizosphere and/or those biochemical processes determining the uptake at root level of nitrogen (N), phosphorus (P), and iron (Fe), that represent the major constraints for crop productivity worldwide. We have isolated novel bacterial strains from the rhizosphere of barley (Hordeum vulgare L.) and tomato (Solanum lycopersicon L.) plants, previously grown in hydroponic solution (either Fe deficient or Fe sufficient) and subsequently transferred onto an agricultural calcareous soil. PGPB have been identified by molecular tools and characterized for their capacity to produce siderophores and indole-3-acetic acid (IAA), and to solubilize phosphate. Selected bacterial isolates, showing contemporarily high levels of the three activities investigated, were finally tested for their capacity to induce Fe reduction in cucumber roots two isolates, from barley and tomato plants under Fe deficiency, significantly increased the root Fe-chelate reductase activity; interestingly, another isolate enhanced the reduction of Fe-chelate reductase activity in cucumber plant roots, although grown under Fe sufficiency.

    From the rhizosphere of two salt tolerant plant species, Hordeum secalinum and Plantago winteri growing in a naturally salt meadow, 100 strains were isolation on enrichment media for various plant growth-promoting (PGP) functions (ACC deaminase activity, auxin synthesis, calcium phosphate mobilization and nitrogen fixation). Based on the taxonomic affiliation of the isolated bacteria and their enrichment medium 22 isolates were selected to test their growth promotion effect on the crop barley (Hordeum vulgare) under salt stress in pot experiment. In parallel the isolates were characterized in pure culture for their plant growth-promoting activities. Surprisingly the best promotors did not display a promising set of PGP activities. Isolates with multiple PGP-activities in pure culture like Microbacterium natoriense strain E38 and Pseudomonas brassicacearum strain E8 did not promote plant growth. The most effective isolate was strain E108 identified as Curtobacterium flaccumfaciens, which increased barley growth up to 300%. In pure culture strain E108 showed only two out of six plant growth promoting activities and would have been neglected. Our results highlight that screening based on pure culture assays may not be suitable for recognition of best plant growth promotion candidates and could preclude the detection of both new PGPR and new plant promotion mechanisms.

  12. Simultaneous estimation of relative biological effectiveness of alpha particles and protons in thermal neutron exposure of barley (Hordeum vulgare L.) seeds

    International Nuclear Information System (INIS)

    The relative biological effectiveness (RBE) of alpha particles and protons emitted during exposure of barley (Hordeum vulgare L.) seeds to thermal neutrons were estimated. sup(10)B-enriched re-dried seeds were irradiated with thermal neutrons or gamma-rays. Two assumptions so far believed that boron distribution was uniform throughout either natural dormant seeds or sup(10)B -enriched seeds, and that boron atoms enter the seeds as freely as water molecules do, were found to be invalid. A boron addition effect (BAE) as high as 58.2 was obtained after thermal neutron exposure of seeds presoaked in 4800 microg/g of sup(10)B-enriched boric acid solution. Estimates of RBE of alpha particles were nearly constant and independent of the contents of absorbed sup(10)B. RBE averaged 55.0 and 55.1 for the seed and spike presoaking methods of boron absorption, respectively. We could also obtain RBE of protons as high as 48.7 and 43.9 for the seed and spike methods, respectively. Boron addition converted the principal capture element during thermal neutron exposure from protons in dormant seeds to boron in sup(10)B enriched-seeds

  13. Development and validation of a terrestrial biotic ligand model predicting the effect of cobalt on root growth of barley (Hordeum vulgare)

    International Nuclear Information System (INIS)

    A Biotic Ligand Model was developed predicting the effect of cobalt on root growth of barley (Hordeum vulgare) in nutrient solutions. The extent to which Ca2+, Mg2+, Na+, K+ ions and pH independently affect cobalt toxicity to barley was studied. With increasing activities of Mg2+, and to a lesser extent also K+, the 4-d EC50Co2+ increased linearly, while Ca2+, Na+ and H+ activities did not affect Co2+ toxicity. Stability constants for the binding of Co2+, Mg2+ and K+ to the biotic ligand were obtained: log K CoBL = 5.14, log K MgBL = 3.86 and log K KBL = 2.50. Limited validation of the model with one standard artificial soil and one standard field soil showed that the 4-d EC50Co2+ could only be predicted within a factor of four from the observed values, indicating further refinement of the BLM is needed. - Biotic Ligand Models are not only a useful tool to assess metal toxicity in aquatic systems but can also be used for terrestrial plants

    Barley (Hordeum vulgare L.) is the most salt-tolerant cereal crop and has excellent genetic and genomic resources. It is therefore a good model to study salt-tolerance mechanisms in cereals. We aimed to determine metabolic differences between a cultivated barley, Clipper (tolerant), and a North African landrace, Sahara (susceptible), previously shown to have contrasting root growth phenotypes in response to the early phase of salinity stress. GC-MS was used to determine spatial changes in primary metabolites in barley roots in response to salt stress, by profiling three different regions of the root: root cap/cell division zone (R1), elongation zone (R2), and maturation zone (R3). We identified 76 known metabolites, including 29 amino acids and amines, 20 organic acids and fatty acids, and 19 sugars and sugar phosphates. The maintenance of cell division and root elongation in Clipper in response to short-term salt stress was associated with the synthesis and accumulation of amino acids (i.e. proline), sugars (maltose, sucrose, xylose), and organic acids (gluconate, shikimate), indicating a potential role for these metabolic pathways in salt tolerance and the maintenance of root elongation. The processes involved in root growth adaptation and the underlying coordination of metabolic pathways appear to be controlled in a region-specific manner. This study highlights the importance of utilizing spatial profiling and will provide us with a better understanding of abiotic stress response(s) in plants at the tissue and cellular level.

    Full Text Available Enterotoxigenic Staphylococcus aureus strains that were isolated from foods were investigated for their ability to develop direct-tolerance and cross-tolerance to sodium chloride (NaCl, potassium chloride (KCl, lactic acid (LA and acetic acid (AA after habituation in sublethal amounts (1/2 of the minimum inhibitory concentration - 1/2 MIC and 1/4 of the minimum inhibitory concentration - 1/4 MIC of Origanum vulgare L. essential oil (OVEO. The habituation of S. aureus to 1/2 MIC and 1/4 MIC of OVEO did not induce direct-tolerance or cross-tolerance in the tested strains, as assessed by modulation of MIC values. Otherwise, exposing the strains to OVEO at sublethal concentrations maintained or increased the sensitivity of the cells to the tested stressing agents because the MIC values of OVEO, NaCl, KCl, LA and AA against the cells that were previously habituated to OVEO remained the same or decreased when compared with non-habituated cells. These data indicate that OVEO does not have an inductive effect on the acquisition of direct-tolerance or cross-tolerance in the tested enterotoxigenic strains of S. aureus to antimicrobial agents that are typically used in food preservation.

    The effect of solvent polarity (methanol and pentane) on the chemical composition of hydrodistilled essential oils (EO's) of Lippia graveolens H.B.K. (MXO) and Origanum vulgare L. (EUO) was studied by GC-MS. Composition of modified starch microencapsulated EO's was conducted by headspace-solid-phase microextraction (HS-SPME). The antimicrobial activity of free and microencapsulated EO's was evaluated. They were tested against Salmonella sp., Brochothrix thermosphacta, Pseudomonas fragi, Lactobacillus plantarum, and Micrococcus luteus. Thymol and carvacrol were among the main components of EO's and their free and microencapsulated inhibitory activity was tested against M. luteus, showing an additive combined effect. Chemical composition of EO's varied according to the solvent used for GC analysis and to volatile fraction as evaluated by HS-SPME. Thymol (both solvents) was the main component in essential oil of MXO, while carvacrol was the main component of the volatile fraction. EUO showed α-pinene (methanol) and γ-terpinene (pentane) as major constituents, the latter being the main component of the volatile fraction. EO's showed good stability after 3 months storage at 4°C, where antimicrobial activity of microencapsulated EO's remained the same, while free EO's decreased 41% (MXO) and 67% (EUO) from initial activity. Microencapsulation retains most antimicrobial activity and improves stability of EO's from oregano. PMID:25177730

    Cultivated barley (Hordeum vulgare L.) is considered as a non-host or inappropriate host species for wheat stripe rust caused by Puccinia striiformis f. sp. tritici. Most barley cultivars show a broad-spectrum resistance to wheat stripe rust. To determine the genes for resistance to wheat stripe rust in barley, a cross was made between a resistant barley line Y12 and a susceptible line Y16. The two parents, F(1) and 147 BC(1) plants were tested at seedling stage with Chinese prevalent race CYR32 of Puccinia striiformis f. sp. tritici by artificial inoculation in greenhouse. The results indicated that Y12 possessed one dominant resistance gene to wheat stripe rust, designated YrpstY1 provisionally. A total of 388 simple sequence repeat (SSR) markers were used to map the resistance gene in Y12 using bulked segregant analysis. A linkage map, including nine SSR loci on chromosome 7H and YrpstY1, was constructed using the BC(1) population, indicating that the resistance gene YrpstY1 is located on chromosome 7H. It is potential to transfer the resistance gene into common wheat for stripe rust resistance. PMID:21039455

    Full Text Available The initial material for performed studies was constituted by hull and hull-less DH lines of spring barley (Hordeum vulgare L.. The kernels were irradiated with helium-neon laser (He-Ne in red light spectrum and at the wavelength of 632 nm. Plants obtained in greenhouse conditions were analyzed for blade area and their photosynthetic activity in flag and penultimate leaves (photosynthetic and transpiration rate, photosynthetic gas efficiency. The results indicated a biostimulation effect of laser light, causing an increase of blade area of flag and penultimate leaves. This effect was higher for flag leaves, and exposure to 180 min of irradiation was more effective as compared to 60 min. The reaction observed depended on the kind of DH lines analyzed, and two of them – R63N/14 and R58N/91 increased their blade area more effectively than others. Simultaneously, photo- synthetic and transpiration rate decreased in dependence on time of irradiation and the kind of DH lines used. On the other hand, gas exchange efficiency defined as photosynthetic coefficient of water use (CO2 assimilation / H2O transpiration increased for all DH lines and laser light exposure as compared to control.

    Barley straw is commonly used as animal feed in many developing countries. Even a small increase in its nutritive value can have a large impact on animal production, and hence, on rural livelihood and human nutrition. Straw quality is strongly affected by environmental factors and is, therefore, difficult to improve with empirical breeding. The objective of this study was to identify molecular markers to facilitate the improvement of straw quality in barley. For this purpose, we have used the genetic linkage map that was already developed for recombinant inbred lines (RILs) of the cross between a Hordeum vulgare cultivar ('Arta') and a H. spontaneum line (H. spontaneum 41-1), covering a total of 890 cM. Straw parameters from RILs grown at Tel Hadya and Breda (ICARDA's research stations) in 2 years (1996/1997 and 1997/1998) were analyzed by NIRS for predicted nutritional characteristics including neutral detergent fiber, acid detergent fiber, lignin, digestible organic matter in dry matter, voluntary intake, crude protein, and straw morphology (the percentage of blades, sheaths, and stems). Localization of QTLs was performed using Windows QTL Cartographer, version 2.0. Seventy-three QTLs were identified, the majority of which (17) in the driest of the four environments. Only six QTLs were identified in two environments; in five cases, one of the two was the wettest environment. This is discussed in relation to the possibility of improving straw quality in favorable environments where yields are higher, rather than in dry environments where straw quality is already relatively good.

    Full Text Available The effects of increasing concentrations of oregano (Origanum vulgare L. and rosemary (Rosmarinus officinalis L. essentials oil (EO on ruminal gas emissions were tested in vitro using 50 mL serum bottles. Each bottle contained a 200 mg substrate (alfalfa hay and corn meal 1:1 and a 20 mL solution composed of a buffered medium and rumen fluid (1:2. The percentage of ruminal fermentation products was quantified by an infrared analyzer. The reduction of total gas production was 6% and 9% respectively when using the 1.5 and 2.0 g/L oregano EO measurements. The reduction of methane production was 55%, 72% and 71% respectively with regard to the 1.0, 1.5 and 2.0 g/L oregano EO doses, while rosemary EO (2.0 g/L reduced the methane production by 9%. The production of ammonia was significantly reduced (59%–78% by all treatments with the exception of rosemary EO at the lowest dose. Dry matter and neutral detergent fiber degradability was reduced by most of the treatments (respectively 4%–9% and 8%–24%. The total volatile fatty acids (VFA concentration was markedly decreased by oregano EO and was not affected by rosemary EO. Both EOs mitigated rumen fermentations, but oregano EO gave rise to the highest reduction in methane and ammonia production. However, further research is needed to evaluate the use of these essential oils as dietary supplements by taking into account the negative effects on feed degradability.

    A C3 monocot, Hordeum vulgare and C3 dicot, Vicia faba, were studied to evaluate the mechanism of inhibition of photosynthesis due to water stress. The net rate of CO2 fixation (A) and transpiration (E) were measured by gas exchange, while the true rate of O2 evolution (J O2) was calculated from chlorophyll fluorescence analysis through the stress cycle (10 to 11 days). With the development of water stress, the decrease in A was more pronounced than the decrease in J O2 resulting in an increased ratio of Photosystem II activity per CO2 fixed which is indicative of an increase in photorespiration due to a decrease in supply of CO2 to Rubisco. Analyses of changes in the J O2 A ratios versus that of CO2 limited photosynthesis in well watered plants, and RuBP pool/RuBP binding sites on Rubisco and RuBP activity, indicate a decreased supply of CO2 to Rubisco under both mild and severe stress is primarily responsible for the decrease in CO2 fixation. In the early stages of stress, the decrease in C i (intercellular CO2) due to stomatal closure can account for the decrease in photosynthesis. Under more severe stress, CO2 supply to Rubisco, calculated from analysis of electron flow and CO2 exchange, continued to decrease. However, C i, calculated from analysis of transpiration and CO2 exchange, either remained constant or increased which may be due to either a decrease in mesophyll conductance or an overestimation of C i by this method due to patchiness in conductance of CO2 to the intercellular space. When plants were rewatered after photosynthesis had dropped to 10-30% of the original rate, both species showed near full recovery within two to four days. PMID:24271534

    WRKY proteins belong to the WRKY-GCM1 superfamily of zinc finger transcription factors that have been subject to a large plant-specific diversification. For the cereal crop barley (Hordeum vulgare), three different WRKY proteins have been characterized so far, as regulators in sucrose signaling, in pathogen defense, and in response to cold and drought, respectively. However, their phylogenetic relationship remained unresolved. In this study, we used the available sequence information to identify a minimum number of 45 barley WRKY transcription factor (HvWRKY) genes. According to their structural features the HvWRKY factors were classified into the previously defined polyphyletic WRKY subgroups 1 to 3. Furthermore, we could assign putative orthologs of the HvWRKY proteins in Arabidopsis and rice. While in most cases clades of orthologous proteins were formed within each group or subgroup, other clades were composed of paralogous proteins for the grasses and Arabidopsis only, which is indicative of specific gene radiation events. To gain insight into their putative functions, we examined expression profiles of WRKY genes from publicly available microarray data resources and found group specific expression patterns. While putative orthologs of the HvWRKY transcription factors have been inferred from phylogenetic sequence analysis, we performed a comparative expression analysis of WRKY genes in Arabidopsis and barley. Indeed, highly correlative expression profiles were found between some of the putative orthologs. HvWRKY genes have not only undergone radiation in monocot or dicot species, but exhibit evolutionary traits specific to grasses. HvWRKY proteins exhibited not only sequence similarities between orthologs with Arabidopsis, but also relatedness in their expression patterns. This correlative expression is indicative for a putative conserved function of related WRKY proteins in mono- and dicot species.

    Molecular size and net charge of isoforms of pathogenesis-related (PR) chitinase, beta-1,3-glucanase and peroxidase were studied in uninfected barley (Hordeum vulgare L., v. Karat) leaves and in barley leaves infected with the pathogenic fungus Drechslera teres f. teres (Sacch.) Shoem. Molecular characteristics were determined by time-dependent polyacrylamide gradient gel electrophoresis under native conditions and by applying an extended version of the computer program MOL-MASS (Rothe, G. M., Weidmann, H., Electrophoresis 1991, 12, 703-709). Uninfected barley leaves contained predominantly one peroxidase isozyme but also three very weak peroxidases. Activities of all of these three peroxidases increased considerably after infection with Drechslera teres. The molecular masses of peroxidases 1 and 3 were estimated to be 38 +/- 5 and 42 +/- 7 kDa and their apparent valences at pH 8.4 were Z = 3.13 and 3.20, respectively. Amongst the chitinase isoforms, chitinase 1 and chitinase 2 appeared after infection, while chitinase 3 was also observed in uninfected leaves of barley. The molecular mass of chitinase 3 (31 +/- 6 kDa; f/fo = 1.20) was larger than that of chitinase 1 (20 +/- 2 kDa; f/fo = 1.04) and chitinase 2 (23 +/- 3 kDa; f/fo = 1.06). The valence of constitutive chitinase 3 (Z = 1.44 +/- 0.81) at pH 8.4 was lower than that of adaptive chitinase 1 (Z = 3.27 +/- 1.02) and chitinase 2 (Z = 2.96 +/- 1.38). Infection of barley leaves with Drechslera teres also induced the hydrolytic enzyme beta-1,3-glucanase 1; beta-1,3-glucanase 2 appeared in uninfected and in infected leaves. Constitutive beta-1,3-glucanase 2 was smaller (molecular mass 19 +/- kDa; f/fo = 1.05) than adaptive beta-1,3-glucanase 1 (molecular mass 26 +/- 4 kDa; f/fo = 1.07). The valence of adaptive beta-1,3-glucanase 1 (Z = 9.58 +/- 4.17) was approximately threefold that of beta-1,3-glucanase 2 (Z = 2.80 +/- 0.93). PMID:9629909

    Background Oregano (Origanum vulgare), sage (Salvia officinalis), and thyme (Thymus vulgaris) are aromatic plants with ornamental, culinary, and phytotherapeutic use all over the world. In Europe, they are traditionally used in the southern countries, particularly in the Mediterranean region. The antimicrobial activities of the essential oils (EOs) derived from those plants have captured the attention of scientists as they could be used as alternatives to the increasing resistance of traditional antibiotics against pathogen infections. Therefore, significant interest in the cultivation of various aromatic and medicinal plants is recorded during the last years. However, to gain a proper and marketable chemotype various factors during the cultivation should be considered as the geographical morphology, climatic, and farming conditions. In this frame, we have studied the antimicrobial efficiency of the EOs from oregano, sage, and thyme cultivated under different conditions in a region of NE Greece in comparison to the data available in literature. Methods Plants were purchased from a certified supplier, planted, and cultivated in an experimental field under different conditions and harvested after 9 months. EOs were extracted by using a Clevenger apparatus and tested for their antibacterial properties (Minimum inhibitory concentration – MIC) against clinical isolates of multidrug resistant Escherichia coli (n=27), Klebsiella oxytoca (n=7), and Klebsiella pneumoniae (n=16) strains by using the broth microdilution assay. Results Our results showed that the most sensitive organism was K. oxytoca with a mean value of MIC of 0.9 µg/mL for oregano EOs and 8.1 µg/mL for thyme. The second most sensitive strain was K. pneumoniae with mean MIC values of 9.5 µg/mL for thyme and 73.5 µg/mL for oregano EOs. E. coli strains were among the most resistant to EOs antimicrobial action as the observed MICs were 24.8–28.6 µg/mL for thyme and above 125 µg/mL for thyme and sage

The antimicrobial activities of the essential oils (EOs derived from those plants have captured the attention of scientists as they could be used as alternatives to the increasing resistance of traditional antibiotics against pathogen infections. Therefore, significant interest in the cultivation of various aromatic and medicinal plants is recorded during the last years. However, to gain a proper and marketable chemotype various factors during the cultivation should be considered as the geographical morphology, climatic, and farming conditions. In this frame, we have studied the antimicrobial efficiency of the EOs from oregano, sage, and thyme cultivated under different conditions in a region of NE Greece in comparison to the data available in literature. Methods: Plants were purchased from a certified supplier, planted, and cultivated in an experimental field under different conditions and harvested after 9 months. EOs were extracted by using a Clevenger apparatus and tested for their antibacterial properties (Minimum inhibitory concentration – MIC against clinical isolates of multidrug resistant Escherichia coli (n=27, Klebsiella oxytoca (n=7, and Klebsiella pneumoniae (n=16 strains by using the broth microdilution assay. Results: Our results showed that the most sensitive organism was K. oxytoca with a mean value of MIC of 0.9 µg/mL for oregano EOs and 8.1 µg/mL for thyme. The second most sensitive strain was K. pneumoniae with mean MIC values of 9.5 µg/mL for thyme and 73.5 µg/mL for oregano EOs. E. coli strains were among the most resistant to EOs antimicrobial action as the observed MICs were 24.8–28.6 µg/mL for thyme and above 125 µg/mL for

Plastic film, straw pulp film and CK treatment were administrated; the effect was compared by measuring relative humidity of soil surface, soil temperature, soil compaction and water content. The results showed that all four factors monitored were lower in the treatment of straw pulp film than the plastic film, among which water content of the former was significantly reduced than the latter(n=3, P<0.05). In the treatment of straw pulp film comparing to CK, soil compaction was significantly reduced(n=3, P<0.05), while no significant difference in soil temperature was shown between the two. The evaporation of soil moisture reduced dramatically in the treatment of straw pulp film, resulting in a 7.59% statistically significant increase in the water content of soil (n=3, P<0.05). In conclusion, the straw pulp film mulch has significantly improved the water conservation of the soil in Hordeum vulgare farmland.

    Thirty samples of Indonesian medicinal plants were tested for their mechanism-based inhibition on cytochrome P450 3A4 (CYP3A4) and CYP2D6 via erythromycin N-demethylation and dextromethorphan O-demethylation activities in human liver microsomes. From screening with 0 and 20min preincubation at 0.5mg/ml of methanol extracts, five plants (Cinnamomum burmani bark, Foeniculum vulgare seed, Strychnos ligustrina wood, Tinospora crispa stem, and Zingiber cassumunar rhizome) showed more than 30% increase of CYP3A4 inhibition, while three (Alpinia galanga rhizome, Melaleuca leucadendron leaf, and Piper nigrum fruit) showed more than 30% increase of CYP2D6 inhibition. In these eight plants, Foeniculum vulgare seed, Cinnamomum burmani bark, and Strychnos ligustrina wood showed time-dependent inhibition on CYP3A4 and Piper nigrum fruit and Melaleuca leucadendron leaf on CYP2D6. Among these, four plants other than Melaleuca leucadendron revealed NADPH-dependent inhibition. Thus, Foeniculum vulgare, Cinnamomum burmani, and Strychnos ligustrina should contain mechanism-based inhibitors on CYP3A4 and Piper nigrum contain that on CYP2D6. PMID:16414224

Fifty patients were randomized to receive one of the five investigational vehicles. Treatment was performed up to complete healing or to a maximum of 29 days. The wound size reduction from baseline was the primary efficacy variable, which was measured by means of a noninvasive laser scanner instrument for wound assessment. In all groups, apart from the foam group, a similar trend toward the reduction of the surface area was observed. The cream showed the greatest effect on the mean reduction of the lesion size. At last visit, six ulcers were healed: two in the cream group, three in the gauze group, and one in the dressing gel group. In the patients treated with the cream, the gauzes, the hydrogel, and the dressing gel, the reduction of lesion size was 40%–50%; the reduction was smaller in the foam group. No impact in terms of age on the healing process was found. The Total Symptoms Score decreased in all groups during the study; a greater efficacy in terms of signs/symptoms was observed in the patients treated with the gauzes. In the dressing gel group, one patient had an infection of the wound after 3 weeks of treatment and 2 of colonization, leading to a systemic antibiotic treatment. The events were judged as nonrelated to the device used. On the basis of the results, it could be argued that the medical device may be useful in the treatment of chronic venous ulcers.

    Two tansy (Tanacetum vulgare L.) essential oils were obtained by steam distillation of the capitula with subsequent liquid-liquid extraction (oil 1) or with use of an auxiliary phase for the trapping of the steam components (oil 2). These oils were investigated against Bacillus subtilis F1276, B. subtilis spizizenii (DSM 618), Xanthomonas euvesicatoria, Pseudomonas syringae pv. maculicola, Ralstonia solanacearum strain GMI1000 and Aliivibrio fischeri, using the coupling of high-performance thin-layer chromatography to direct bioautography (HPTLC-DB). Using this method with the potato and tomato pathogen R. solanacearum is shown for the first time. Due to the advanced extraction process, oil 2 was richer in components and provided more inhibition zones. The main bioactive components were identified by scanning HPTLC-Direct Analysis in Real Time mass spectrometry (HPTLC-DART-MS) and solid-phase microextraction gas chromatography electron impact MS (SPME-GC-EI-MS) as cis- and trans-chrysanthenol as well as trans-chrysanthenyl acetate. cis-Chrysanthenol exhibited antibacterial effects against all tested bacteria, whereas trans-chrysanthenol inhibited B. subtilis, R. solanacearum and A. fischeri. trans-Chrysanthenyl acetate was an inhibitor for X. euvesicatoria, R. solanacearum and A. fischeri. Although HPTLC-DART-MS resulted in a comparable fragmentation, the ionization characteristics and the recorded mass spectra clearly showed that DART is a softer ionization technique than EI. It is also more affected by ambient conditions and thus prone to additional oxidation products. PMID:26499972

  16. Essential oil and composition of anise (pimpinella anisum l.) with varying seed rates and row spacing

    International Nuclear Information System (INIS)

    Two year study was carried out to explore the effect of seed rate and row spacing on the fruit yield, essential oil yield and composition of aniseed. The study factors included seed rate (6 g, 12 g, 24 g/10 m2) and row spacing (15 cm, 25 cm, 37.5 cm. A significantly higher fruit yield was produced at narrow row spacing of 15 cm among treatments. Wider row spacing produced markedly higher essential oil than narrow row spacing. Essential oil accumulation decreased as planting densities increased. The major constituent of anise oil was trans-anethole (82.1%) followed by himachalene (7.0%). The quality parameters including estragol, himachalene and trans-anethole were significantly affected by different row spacing. Plant grown at 37.5 cm row spacing accumulated the highest estragol and trans-anethole concentration among the row spacing treatments. It can be concluded that higher plant density and wider row spacing increased the disease infestation and lodging cultivar Enza Zaden in current study exhibited high concentration trans-anethole in essential oil composition therefore is a good quality chemotype.

  18. Tracer-aided studies on the fate and effects of sulphur dioxide in Spinacia oleracea L. and Triticum vulgare. Part of a coordinated programme on isotopic-tracer-aided studies of atmospheric sulphur pollutant - plant interactions

    International Nuclear Information System (INIS)

    Wheat, Triticum vulgare and spinach, Spinacia oleracea plants were exposed to two different concentrations of 35SO2 - released by lactic acid from Na235SO3 - for 45 minutes, and distribution of radioactivity was studied in leaves, stem and roots. After 24 hours, the specific activity of the leaves of both plants was reduced while that of the roots was increased, suggesting 35S translocation from leaves to roots. Translocation to the stem and roots of 35S products was much higher in wheat than in spinach. In leaves of both plant species, ethanol-soluble products were much higher than the ethanol-insoluble fraction during the first 6 hours of exposure. The ethanol-soluble fraction contained sulphate, sulphite and unidentified material. The study suggests that SO2 is metabolized in preference to endogenous S, that the wheat plant is more susceptible to SO2, and that tolerance is related to the capacity of converting SO2 to sulphate and reducing its further conversion. Uptake of 35SO2 by young and old wheat and spinach plants was studied with a view to determining susceptibility to SO2 exposure as a function of the developmental stage of the plant. In wheat, young plants metabolize endogenous sulphur in preference to absorbed SO2 while older plants are active in converting absorbed sulphur into organic (ethanol-insoluble) form. In spinach, young plants are more active in transporting 35S products from leaves to roots and older plants show higher incorporation percentage of 35S into the organic fraction of leaves. Uptake of 1-14C-acetate by lipids of leaf discs from spinach and wheat was investigated in normal and SO2-stressed plants. The incorporation of radioacetate into lipids of leaf tissues of both plants was strongly inhibited in SO0 plants. Also U-14C-lysine incorporation into proteins of leaf tissue was significantly inhibited by 0.2-2.0 ppm aqueous SO2

    1. The Streptococcus zymogenes assay procedure was modified and used in the estimation of available methionine and relative nutritional value in rice (Oryza sativa L.), sorghum (Sorghum vulgare Pers.), barley and field beans (Vicia faba L.). The results were assessed in relation to the content of tannins and 'dye-binding lysine', and to published information on the nutritional quality of some of the test samples. 2. In grain of ten varieties of sorghum, for which other workers had reported a correlation (r -0.82; P less than 0.01) between tannin content and amino acid digestibility in chicks, the available methionine content ranged from 6.3 to 17.7 g/kg protein (nitrogen x 6.25) and was highly correlated with tannin content (r -0.97; P less than 0.001). The content of total methionine and dye-binding lysine varied little between varieties and was not related to tannin content. 3. In nine samples of rice the availability of methionine was uniformly high, in accordance with literature values for true digestibility of the N. 4. In field beans the presence of tammins in the seed coat was associated with a significant (P less than 0.001) reduction in the availability of methionine. In eleven tannin-free varieties the coefficient of availability averaged 0.791, compared with 0.685 in eleven tannin-containing varieties. The standard deviation associated with both values was 0.04. There was no such difference between the corresponding dye-binding lysine values. 5. Thirty-three samples of barley were examined, representing fourteen varieties, four of which had been grown at several widely different latitudes in England and Sweden. There was little difference in methionine content between samples. The average availability coefficient for eighteen samples grown in England was 0.995+/-0.044, and for fifteen varieties grown in Sweden it was 0.851+/-0.042. The difference was not associated with any difference in tannin content, which was uniformly low. The findings contradict

    Full Text Available Four levels of N, P and K nutrition (poor, moderate, satisfactory and high and all their possible combinations with 64 treatments in two replications (128 plots were studied in a long term field trial on barley yield and malting quality. A standard East-European spring barley "Opal" (bred in Czechoslovakia was grown in 1986, 13th year of the agricultural experiment, involving various crops in previous years, on a calcareous loamy chernozem soil. The optimum fertility levels for yield enhancement resulted in the poorest malting quality: low modification and extract but long saccharification time and high protein. To solve this problem the brewing industry will have to apply the well-known technological methods available since growers are not likely to give up their fertilizers. Applying soil and plant analysis data, having knowledge about both soil and plant optimum values, the danger of the excessive use of fertilizers can be realized and decreased.

    Full Text Available Sunflower (Helianthus annuus L. oil was coloured with pigments extracted from green leaves. Different amounts (0, 200, 400, 600, and 800 ppm of oleoresin extracted from oregano (Origanum vulgare L. as antioxidant, were added to the coloured oil. As controls, coloured oil without oleoresin (A.C. and pure oil (A.P. were used. The samples were stored at room temperature (10-20 ºC in the dark for up to six months. During this time the oxidation of oleic acid, linoleic acid, peroxides index and the chlorophyll pigments were analized and the colour of the oil was determined. During the first month, only the ratio of chlorophyll to pheophytin changed, whereas all the other parameters stayed constant, independently to the amount of antioxidant added. Since among the treatments A.C. and A.P. not significant differences (p >0,05 were found, for oleic and linoleic methyl ester acids and peroxides index, it can be concluded that the edible, coloured sunflower oil shows an equivalent stability to the pure oil, when stored at darkness for three or six month. There was not observed an evident antioxidant action with the added oregano oleorresin to the coloured oil.Se estudió la estabilidad de aceite comestible de girasol (Helianthus annuus L. de marca comercial sin antioxidantes, coloreado con pigmentos obtenidos de hojas verdes.

All of the essential oils and the components exerted a remarkable inhibition ranging between 32 and 64 μg/mL against all of these strains as strong as the references (ampicilin and oflaxocin) inhibiting at 32 μg/mL. Besides, chemical compositions of the essential oils were elucidated by gas chromatography-mass spectrometry (GC-MS). The essential oils and the pure components widely found in essential oils screened herein have shown remarkable inhibition against ESBL-producing K. pneumoniae strains, which leads to the suggestion that they may be used as food preservatives for this purpose. Practical Application:  The essential oils obtained from Foeniculum vulgare, Mentha piperita and M. spicata, O.cimum basilicum, Origanum majorana, O. onites, O. vulgare, and Satureja cuneifolia as well as common essential oil components have shown notable inhibitory effects against 10 isolated strains of Klebsiella pneumoniae producing extended-spectrum beta-lactamase (ESBL) enzyme and they might be used as food preservative or ingredient.

  18. Antimicrobial Activity of Essential Oils Extracted from Gamma Irradiated and Stored Anise (Pimenella Anisum) and Black Cumin (Negilla Sativa) Seeds

    International Nuclear Information System (INIS)

    Anise and black cumin seeds were gamma irradiated to doses of 5, 10, 20 and 40 kGy then these seeds were stored to periods of 0, 4, 8 and 12 months. In all treatments, essential oils were extracted at concentrations 500, 1000, 2000, 4000 and 6000 ppm. The inhibitory effect of the different oil concentrations was tested against some microorganism which included bacteria (E. coli and B. cereus), fungi (A. niger and P. citrinum) and yeast (S. lypoytica and K. marxianus). Each of the extracted oil showed different magnitudes to inhibit the growth of the tested microorganisms. However, exposing the aromatic seeds to gamma irradiation before oil extraction was resulted in stimulation in the biological activity of the produced oil. Maximum stimulation was exerted at irradiation dose of 20 kGy. However, the antimicrobial activity of the tested oils was relatively declined when seeds were stored up to 12 months but this decrease was counteracted when seeds were irradiated before storage, thus, gamma radiation showed a beneficial impact to maintain the biological activity of the essential oils during seeds storage.

Single main components present in high amounts in such EOs were also tested. Different dermatophyte species showed remarkable differences in sensitivity. In general, more effective EOs were T. serpyllum (MIC range 0.025%-0.25%), O. vulgare (MIC range 0.025%-0.5%) and L. cubeba (MIC range 0.025%-1.5%). F. vulgare showed a moderate efficacy against geophilic species such as M gypseum and T terrestre. Among single main components tested, neral was the most active (MIC and MFC values 5 0.25%). The results of the present study seem to be promising for an in vivo use of some assayed EOs. PMID:26434145

    The peculicidal activity of eight plant essential oils in 75% isopropyl alcohol was in vitro investigated. Of them, the substances that were most active against lice were tea tree (Melaleuca), eucalyptus, neem, citronella (Cymbopogon nardus), and clove (Syzygium aromaticum) oils; KT50 was not more than 3 minutes on average; KT95 was 4 minutes. After evaporating the solvent, only five (tea tree, cassia, clove, anise (Anisum vulgare), and Japanese star anise (Illicium anisatum) oils) of the eight test botanical substances were active against lice. At the same time, KT50 and KT95 showed 1.5-5-fold increases. Citronella and anise oils had incomplete ovicidal activity. Since the lice were permethrin-resistant, the efficacy of preparations based on essential oils was much higher than permethrin. PMID:25296426

    Essential oils (EO) possess antimicrobial, anti-inflammatory, insect repellent, anti-cancer, and antioxidant properties, among others. In the present work, the antioxidant, anti-inflammatory and anti-proliferative activities of Moroccan commercial EOs (Citrus aurantium, C. limon, Cupressus sempervirens, Eucalyptus globulus, Foeniculum vulgare and Thymus vulgaris) were evaluated and compared with their main constituents. T. vulgaris EO showed the best free radicals scavenging capacity. This EO was also the most effective against lipid peroxidation along with C. limon and F. vulgare EOs. C. sempervirens EO was the most effective in scavenging NO free radicals, whereas C. limon EO showed the best chelating power. Not all of the major compounds of the EO were responsible for the whole activity of the EOs. T. vulgaris EO showed the best anti-proliferative activity against THP-1 cells in contrast to that of F. vulgare. The antioxidant and anti-inflammatory activities of the EOs were plant species dependent and not always attributable to the EOs main components. Nevertheless, the EOs anti-proliferative activities were more related to their main components, as with T. vulgaris, C. limon, E. globulus and C. sempervirens. PMID:24868891

    Thirteen elements (Na, K, Ca, Mg, Fe, Mn, Cu, Zn, Cr, Co, Cd, Ni and Pb) in 11 different wild edible plants (WEP) (Amaranthus retroflexus, Foeniculum vulgare, Cichorium intybus, Glebionis coronaria, Sonchus spp., Borago officinalis, Diplotaxis tenuifolia, Sinapis arvensis, Papaver rhoeas, Plantago lagopus and Portulaca oleracea) collected from countryside and urban areas of Bari (Italy) were determined. B.officinalis and P.rhoeas could represent good nutritional sources of Mn and Fe, respectively, as well as A.retroflexus and S.arvensis for Ca. High intake of Pb and Cd could come from P.lagopus and A.retroflexus (1.40 and 0.13 mg kg(-1) FW, respectively). WEP may give a substantial contribution to the elements intake for consumers, but in some cases they may supply high level of elements potentially toxic for human health. Anyway, both ANOVA and PCA analyses have highlighted the low influence of the harvesting site on the elements content. PMID:25660854

    It was recently discovered that exposure to small concentrations of the essential oils of sweet fennel (Foeniculum vulgare Mill) or pignut [Hyptis suaveolens (L.) Poit] can be used to control aphids. What is not known is whether these oils also influence honeybee behavior. Experiments using both harnessed and free-flying foragers at concentrations used to control aphids showed that bees readily associated the odors with a reward, discriminated between them, and were not repelled. Honeybees, however, would not consume the oils when mixed with sucrose to create an unconditioned stimulus. An experiment in which harnessed bees consumed various concentrations showed that concentrations greater than 50% were detrimental. The experiments reported here provide further evidence supporting the use of conditioning techniques to evaluate the use of essential oils on honey bee behavior. (author)

    Cultivated and wild growing samples of fennel (Foeniculum vulgare Mill., Apiaceae) from R. Macedonia were studied for their volatiles and fatty acid composition. The main essential oil components isolated via hydrodistillation were: trans-anethole (>80%), estragole (hexane and dichloromethane (3:1, v/v) in a Soxhlet extraction followed by transesterification. The obtained extracts were then characterized and the dominant fatty acid was 18:1 (petroselinic and oleic acid) 75.0-82.8%, followed by 18:2 (linoleic acid) 10.8-16.2% and other fatty acids: palmitic (4.3-6.9%), stearic (1.2-1.7%) and myristic (0-2.9%). The results for the volatile fraction after Soxhlet extraction and transesterification did not significantly differ from results obtained after hydrodistillation, especially for the main components (trans-anethole, estragole, fenchone and limonene), implying that the developed method can be used for simultaneous determination of volatiles and fatty acids.

    International Nuclear Information System (INIS)

    In order to evaluate the effects of radioactivity on active vegetal substances, samples of Fennel (Foeniculum vulgare Miller., fructus), Guarana (Paulinia cupana, Kunth, semen), Gingko (gingko biloba, L., folium), and Kawa-Kawa (Piper methysticum G. Forst, rhizoma), were treated with scaling doses (0 to 25 KGy) of gamma radiation (Co60). The 'blind test' methodology was used. The active substances from each sample were analysed by qualitative and quantitative methods after radiation. There were no significant differences seen between the control sample (0 KGy) and the irradiated samples. Microbe contamination was significantly reduced, about 10000 CFU/g, with the initial 5 KGy dose. It was concluded that gamma radiation can be used as an alternative procedure to reduce microbiologic contamination in medicinal plants. Before this procedure can be extended to other medicinal plants, more specific analytical methods are recommended to verify possible structural alterations in active vegetal molecules. (author)

    Consumers demand more and more so-called "natural" products and, therefore, the aim of this work was to compare the effects of natural versus synthetic antioxidant preservatives in yogurts. Matricaria recutita L. (chamomile) and Foeniculum vulgare Mill. (fennel) decoctions were tested as natural additives, while potassium sorbate (E202) was used as a synthetic additive. The fortification of yogurts with natural and synthetic antioxidants did not cause significant changes in the yoghurt pH and nutritional value, in comparison with control samples (yogurt without any additive). However, the fortified yogurts showed higher antioxidant activity, mainly the yogurts with natural additives (and among these, the ones with chamomile decoction). Overall, it can be concluded that plant decoctions can be used to develop novel yogurts, by replacing synthetic preservatives and improving the antioxidant properties of the final product, without changing the nutritional profile.

    Globally, there is a trend for healthy food products, preferably incorporating natural bioactive ingredients, replacing synthetic additives. From previous screening studies, extracts of Foeniculum vulgare Mill. (fennel) and Matricaria recutita L. (chamomile) maintained nutritional properties and improved the antioxidant activity of cottage cheese. Nevertheless, this effect was limited to 7 days. Accordingly, aqueous extracts of these plants were microencapsulated in alginate and incorporated into cottage cheese to achieve an extended bioactivity. Plain cottage cheese, and cheese functionalized by direct addition of free decoctions, were prepared and compared. Independently of plant species, "functionalization type" factor did not show a significant effect on the nutritional parameters, as also confirmed in the linear discriminant analysis, where these parameters were not selected as discriminating variables. Furthermore, samples functionalized with microencapsulated extracts showed higher antioxidant activity after the 7th day, thereby demonstrating that the main purpose of this experimental work was achieved.

    Full Text Available Croatia is a country of diverse plant use traditions, which are still insufficiently documented. The aim of this study was to document local traditions of using wild food plants around Lake Vrana (northern Dalmatia, Zadar region.  We interviewed 43 inhabitants of six traditional villages north of Lake Vrana. On average 12 species were listed, which in total produced an inventory of 55 food plants and 3 fungi taxa. Wild vegetables were most widely collected, particularly by older women who gathered the plants mainly when herding their flocks of sheep. Wild fruits and mushrooms were rarely collected. The former used to be an important supplementary food for children, or for everyone during times of food shortage, and the latter were relatively rare due to the dry climate and shortage of woods. The most commonly collected plants are wild vegetables: Cichorium intybus, Foeniculum vulgare, Sonchus oleraceus, Asparagus acutifolius, Papaver rhoeas, Rumex pulcher, Daucus carota, Allium ampeloprasum and Silene latifolia.

    Full Text Available The commercial essential oils of Citrus aurantium L., Cupressus sempervirens L., Eucalyptus globulus Labill., Foeniculum vulgare Mill. and Thymus vulgaris L., isolated by steam distillation by a company of Morocco were evaluated in terms of in vitro antioxidant activity through several methods. In vitro acetylcholinesterase inhibitory activity was also determined. Citrus limon (L. Burm. f. oil was also studied, but it was obtained by peel expression. The best antioxidant was T. vulgaris oil, independent of the method used, mainly due to the presence of the phenolic monoterpenes thymol and carvacrol, which when studied as single compounds also presented the best activities. Concerning the acetylcholinesterase inhibition activity, E. globulus was the most effective. Nevertheless its main components 1,8-cineole and limonene were not the most active, a feature that corresponded to d-3-carene.

    International Nuclear Information System (INIS)

    A reliable protocol for regenerating barley from seedling explants, including leaf bases with a complete apical meristem, has been developed at the Institute of Genetic Engineering. The system was established with Bulgarian barley cultivars (Ruen, Karnobat, Obzor and Yubilei) and reconstructed genotypes (K. Gecheff IG). Pretreatment of the mature embryos with a high concentration of 2.4D generated valuable and stable genetic deviations in the regenerants. The brewery cultivar Ruen was selected as the model genotype. It has been demonstrated that genetic variations, such as higher yield, earlier maturation and lower protein content, have been induced and maintained for 5 years. Comparative experiments, including treatment of barley mature seeds with 60Co gamma rays (10 and 20 krad) and sodium azide (1.10-3 M and 5 x 10-4 M), were also carried out. The results obtained showed that both treatments stimulated calusogenesis and regeneration of the plants. Molecular markers such as proteins, restriction fragment length polymorphisms (RFLPs) and random amplified polymorphic DNAs (RAPDs) were applied in studies on the mutagenic effects of 2.4D, gamma rays and sodium azide, and a combination threof, on the quality and quantity of the genetic diversification generated in tissue culture of the Bulgarian barley cultivars Ruen, Karnobat, Obzor and Yubilei and the reconstructed genotypes

    Full Text Available BACKGROUND: Endogenous phytase plays a crucial role in phytate degradation and is thus closely related to nutrient efficiency in barley products. The understanding of genetic information of phytase in barley can provide a useful tool for breeding new barley varieties with high phytase activity. METHODOLOGY/PRINCIPAL FINDINGS: Quantitative trait loci (QTL analysis for phytase activity was conducted using a doubled haploid population. Phytase protein was purified and identified by the LC-ESI MS/MS Shotgun method. Purple acid phosphatase (PAP gene was sequenced and the position was compared with the QTL controlling phytase activity. A major QTL for phytase activity was mapped to chromosome 5 H in barley. The gene controlling phytase activity in the region was named as mqPhy. The gene HvPAP a was mapped to the same position as mqPhy, supporting the colinearity between HvPAP a and mqPhy. CONCLUSIONS/SIGNIFICANCE: It is the first report on QTLs for phytase activity and the results showed that HvPAP a, which shares a same position with the QTL, is a major phytase gene in barley grains.

    Plant essential oils from 40 plant species were tested for their insecticidal activities against larvae of Lycoriella ingénue (Dufour) using a fumigation bioassay. Good insecticidal activity against larvae of L. ingenua was achieved with essential oils of Chenopodium ambrosioides L., Eucalyptus globulus Labill, Eucalyptus smithii RT Baker, horseradish, anise and garlic at 10 and 5 microL L(-1) air. Horseradish, anise and garlic oils showed the most potent insecticidal activities among the plant essential oils. At 1.25 microL L(-1), horseradish, anise and garlic oils caused 100, 93.3 and 13.3% mortality, but at 0.625 microL L(-1) air this decreased to 3.3, 0 and 0% respectively. Analysis by gas chromatography-mass spectrometry led to the identification of one major compound from horseradish, and three each from anise and garlic oils. These seven compounds and m-anisaldehyde and o-anisaldehyde, two positional isomers of p-anisaldehyde, were tested individually for their insecticidal activities against larvae of L. ingenua. Allyl isothiocyanate was the most toxic, followed by trans-anethole, diallyl disulfide and p-anisaldehyde with LC(50) values of 0.15, 0.20, 0.87 and 1.47 microL L(-1) respectively. PMID:16786497

    The effect of aromatic plants on number of twospotted spider mite (TSSM), Tetranychus urticae Koch, when intercropped with strawberry were assessed in the field. During the first year, chives (Allium schoenoprasum L.), coriander (Coriandrum sativum L.), fennel (Foeniculum vulgare Mill.), garlic (Allium sativum L.), oregano (Origanum vulgare L.), or sweet marjoram (Origanum majorana L.) were intercropped with strawberry. Assessments were performed on TSSM populations by taking six samples from July 20 to September 20, 2012. During the second year, garlic plants were intercropped between rows of strawberry at three densities in greenhouse and field. Mobile forms and eggs numbers (only in field) of TSSM were evaluated from April 18 to June 05 (greenhouse) and June 06 to August 14, 2013 (field). It was found that intercropping with garlic caused a greater reduction of TSSM (up to 52 %) in strawberry plants when higher populations of TSSM occurred in the field. TSSM reduction was found in one sample when fennel and chives were intercropped with strawberries (42 and 50 % reduction, respectively); this also occurred when populations of TSSM were higher. The three densities of garlic plants (one, two and three rows among the strawberry rows) reduced TSSM mobile forms by 49, 53 and 60 % (greenhouse) and 44, 51 and 65 % (field), and eggs by 38, 43 and 64 % (field), respectively. The results suggest that intercropping garlic plants between strawberry rows is a promising strategy to reduce TSSM populations. PMID:27085718

    The ethnopharmacology for treatment of parasitic infections facilitates and directs the search for new chemical entities. In this direction, this study evaluated the cytotoxicity in vitro, against trophozoites of Giardia lamblia, of aqueous extracts of leaves Achyrocline satureioides (Lam.) DC., barks of Eugenia uniflora L., aerial parts of Foeniculum vulgare Miller, and barks of Psidium guajava L. These plants are traditionally used for the treatment of diarrhea by the indigenous population Mbyá-Guarani, located at the Lomba do Pinheiro, Porto Alegre, Rio Grande do Sul, Brazil. The in vitro susceptibility qualitative analysis of G. lamblia to aqueous extracts was performed in serial dilutions from 2.5 to 0.02 mg/mL. Results revealed the minimal inhibitory concentrations: 0.313 mg/mL for A. satureioides and E. uniflora, 0.02 mg/mL for P. guajava, and F. vulgare did not present any cytotoxic effect. Quantitative assays of viable trophozoites, showed that A. satureioides presented the highest cytotoxic effect (93.5%), followed by P. guajava (82.2%), and E. uniflora (67.3%). Indigenous Guarani use mainly A. satureioides for the treatment of diarrhea, revealing the conformity with results obtained in vitro. Bioguided assays are necessary to identify the compounds responsible for the activity of the aqueous extract of A. satureioides. PMID:19153765

    The zoophilic dermatophyte Microsporum canis has cats as natural reservoir, but it is able to infect a wide range of hosts, including humans, where different clinical features of the so-called ringworm dermatophytosis have been described. Human infections are increasingly been reported in Mediterranean countries. A reliable control program against M. canis infection in cats should include an antifungal treatment of both the infected animals and their living environment. In this article, a herbal mixture composed of chemically defined essential oils (EOs) of Litsea cubeba (1%), Illicium verum, Foeniculum vulgare, and Pelargonium graveolens (0.5% each) was formulated and its antifungal activity assessed against M. canis arthrospores which represent the infective environmental stage of M. canis. Single compounds present in higher amounts in the mixture were also separately tested in vitro. Litsea cubeba and P. graveolens EOs were most effective (minimum inhibitory concentration (MIC) 0.5%), followed by EOs of I. verum (MIC 2%) and F. vulgare (MIC 2.5%). Minimum fungicidal concentrations (MFC) values were 0.75% (L. cubeba), 1.5% (P. graveolens), 2.5% (I. verum) and 3% (F. vulgare). MIC and MFC values of the mixture were 0.25% and 0.5%, respectively. The daily spray of the mixture (200 μL) directly onto infected hairs inhibited fungal growth from the fourth day onwards. The compounds present in higher amounts exhibited variable antimycotic activity, with MIC values ranging from >10% (limonene) to 0.1% (geranial and neral). Thus, the mixture showed a good antifungal activity against arthrospores present in infected hairs. These results are promising for a further application of the mixture as an alternative tool or as an adjuvant in the environmental control of feline microsporosis. PMID:25854840

    Full Text Available A preliminary study on larvicidal activity against laboratory-colonized Anopheles cracens mosquitos revealed that five of ten plant oils at concentration of 100 ppm showed 95–100% larval mortality. The essential oils of five plants, including Piper sarmentosum, Foeniculum vulgare, Curcuma longa, Myristica fragrans, and Zanthoxylum piperitum, were then selected for chemical analysis, dose-response larvicidal experiments, and combination-based bioassays. Chemical compositions analyzed by gas chromatography coupled to mass spectrometry demonstrated that the main component in the oil derived from P. sarmentosum, F. vulgare, C. longa, M. fragrans, and Z. piperitum was croweacin (71.01%, anethole (63.00%, ar-turmerone (30.19%, safrole (46.60%, and 1,8-cineole (21.27%, respectively. For larvicidal bioassay, all five essential oils exerted promising efficacy in a dose-dependent manner and different performances on A. cracens after 24 hours of exposure. The strongest larvicidal potential was established from P. sarmentosum, followed by F. vulgare, C. longa, M. fragrans, and Z. piperitum, with LC50 values of 16.03, 32.77, 33.61, 40.00, and 63.17 ppm, respectively. Binary mixtures between P. sarmentosum, the most effective oil, and the others at the highest ratio were proved to be highly efficacious with a cotoxicity coefficient value greater than 100, indicating synergistic activity. Results of mixed formulations of different essential oils generating synergistic effects may prove helpful in developing effective, economical, and ecofriendly larvicides, as favorable alternatives for mosquito management.

    Helicobacter pylori is the major etiologic agent of such gastric disorders as chronic active gastritis and gastric carcinoma. Over the past few years, the appearance of antibiotic-resistant bacteria has led to the development of better treatments, such as the use of natural products. This study evaluated the anti-H. pylori activity of 17 Mexican plants used mainly in the northwestern part of Mexico (Sonora) for the empirical treatment of gastrointestinal disorders. The anti-H. pylori activity of methanolic extracts of the plants was determined by using the broth microdilution method. The 50% minimum inhibitory concentrations ranged from less than 200 to 400 μg/mL for Castella tortuosa, Amphipterygium adstringens, Ibervillea sonorae, Pscalium decompositum, Krameria erecta, Selaginella lepidophylla, Pimpinella anisum, Marrubium vulgare, Ambrosia confertiflora, and Couterea latiflora and were greater than 800 μg/mL for Byophyllum pinnatum, Tecoma stans linnaeus, Kohleria deppena, Jatropha cuneata, Chenopodium ambrosoides, and Taxodium macronatum. Only Equisetum gigantum showed no activity against H. pylori. This study suggests the important role that these plants may have in the treatment of gastrointestinal disorders caused by H. pylori. The findings set the groundwork for further characterization and elucidation of the active compounds responsible for such activity. PMID:21663492

    We have tested acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory activities of nineteen essential oils obtained from cultivated plants, namely one from Anethum graveolens L. (organic fertilizer), two from Foeniculum vulgare Mill. collected at fully-mature and flowering stages (organic fertilizer), two from Melissa officinalis L. (cultivated using organic and chemical fertilizers), two from Mentha piperita L. and M. spicata L. (organic fertilizer), two from Lavandula officinalis Chaix ex Villars (cultivated using organic and chemical fertilizers), two from Ocimum basilicum L. (green and purple-leaf varieties cultivated using only organic fertilizer), four from Origanum onites L., O. vulgare L., O. munitiflorum Hausskn., and O. majorana L. (cultivated using organic fertilizer), two from Salvia sclarea L. (organic and chemical fertilizers), one from S. officinalis L. (organic fertilizer), and one from Satureja cuneifolia Ten. (organic fertilizer) by a spectrophotometric method of Ellman using ELISA microplate-reader at 1 mg/ml concentration. In addition, a number of single components widely encountered in most of the essential oils [gamma-terpinene, 4-allyl anisole, (-)-carvone, dihydrocarvone, (-)-phencone, cuminyl alcohol, cumol, 4-isopropyl benzaldehyde, trans-anethole, camphene, iso-borneol, (-)-borneol, L-bornyl acetate, 2-decanol, 2-heptanol, methyl-heptanol, farnesol, nerol, iso-pulegol, 1,8-cineole, citral, citronellal, citronellol, geraniol, linalool, alpha-pinene, beta-pinene, piperitone, iso-menthone, menthofurane, linalyl oxide, linalyl ester, geranyl ester, carvacrol, thymol, menthol, vanilline, and eugenol] was also screened for the same activity in the same manner. Almost all of the essential oils showed a very high inhibitory activity (over 80%) against both enzymes, whereas the single components were not as active as the essential oils. PMID:18810999

    Twelve medicinal plants and a commercially used drug Ivermectin were examined for insecticidal activity against Melophagus ovinus sheep ked at different time intervals using in vitro adult immersion test. The findings show that at 3.13 µL/mL, 6.25 µL/mL and 12.5 µL/mL concentration of Cymbopogon citratus, Foeniculum vulgare and Eucalyptus globulus essential oils respectively, recorded 100% mortalities against M. ovinus within 3 hour of exposure. Significantly higher insecticidal activity of essential oils was recorded (P = 0.00) when compared to 10  μ g/mL Ivermectin after 3-hour exposure of M. ovinus at a concentration of ≥1.57  μ L/mL, ≥3  μ L/mL, and ≥12.7  μ L/mL essential oils of C. citratus, F. vulgare, and E. globulus, respectively. Among essential oils, C. citratus has showed superior potency at a three-hour exposure of the parasite (P = 0.00) at a concentration of ≥0.78  μ L/mL. Strong antiparasitic activity was recorded by aqueous extract of Calpurnia aurea (80% mortality) at a concentration of 200 mg/mL within 24 h among aqueous extracts of 9 medicinal plants. The results indicated all the four medicinal plants, particularly those tested essential oils, can be considered as potential candidates for biocontrol of M. ovinus sheep ked. PMID:24649357

    The Citadel, part of the pre-Hispanic city of Teotihuacan and listed as a World Heritage Site, harbors irreplaceable archaeological walls and murals. This city was abandoned by the 7th century and its potential deterioration represents a noteworthy loss of the world's cultural heritage. This research consisted of isolation and identification of bacteria and fungi contributing to this deterioration from walls of a pre-Hispanic city. In addition, silver nanoparticles (AgNP) produced, using a green synthesis method, were tested as potential inhibitors of microbes. AgNP of different sizes and concentrations were tested using in situ assays. Leaf aqueous extracts from two plants species (Foeniculum vulgare and Tecoma stans) and two extraction procedures were used in the NP synthesis. The potential of AgNP as preventive/corrective treatments to protect stucco materials from biodeterioration, as well as the microbial inhibition on three stone materials (stucco, basalt and calcite) was analyzed. Twenty-three bacterial species belonging to eight genera and fourteen fungal species belonging to seven genera were isolated from colored stains, patinas and biofilms produced on the surfaces of archaeological walls from the pre-Hispanic city, Teotihuacan. AgNP from F. vulgare were more effective for in vitro microbial growth inhibition than those from T. stans. Bacteria were less sensitive to AgNP than fungi; however, sensitivity mainly depended on the microbial strain and the plant extract used to prepare AgNP. The use of AgNP as a preventive or corrective treatment to decrease microbial colonization in three kinds of stone used in historical walls was successful. Calcite was more colonized by Alternaria alternata, but less by Pectobacterium carotovorum. This is the first study at different scales (in vitro and tests on different stone types) of inhibition of biodeterioration-causing microorganisms isolated from an archaeological site by green synthesized AgNP.

    Two extraction methods for subsequent gas chromatographic (GC) determination of volatiles from freshly harvested and aged fennel fruit samples (Foeniculum vulgare Mill.,ssp. vulgare var. dulce) have been compared. Hydrodistillation followed by GC-FID and GC-MS analysis was used as a standard method for essential oil characterization, while static headspace followed by GC (SHS-GC-FID) was used as a comparative method for determination of volatile components. As the fennel fruit ages, there is a gradual loss of the volatile components as indicated by the lower yield of essential oil and lower content of volatiles, as indicated by the alternative SHS-GC-FID analysis. Slight differences observed for the main components (trans-anethole, estragole, fenchone, and limonene) using the two methods are negligible, indicating that these volatiles did not undergo chemical transformation during the sample preparation procedures. A difference in anisaldehyde content was observed when the composition of the hydrodistilled essential oil was compared with the SHS-GC-FIDanalysis of volatiles and explanation for the variation of anisaldehyde content and the origin of other compounds was suggested. Comparison of the obtained results showed that limonene oxides, carvone and carveolare detectable in SHS-GC-FID analysis of the aged fennel fruits, while in hydrodistilled samples analyzed by GC-FID they were not present. Another observed difference was the appearance of products in significant amounts with higher retention times than trans-anethole, namely threo- and erythro-anethole β-hydroxymethylether and anethole glycol that are not detectable in the essential oil obtained by hydrodistillation. So, the relative abundance of the major components is comparable between these two methods for fennel seed up to 3 years from harvest and they can be used interchangeably depending on the purpose and amount of material. Furthermore, SHS-GC-FID can be used for assessment of maximum storage time

Methods: The amount, diversity and composition of Lactobacilli in rat colon and rectum were analyzed with Ribotype abundance ( S) , Shannon diversity index ( H) , Evenness index and Jacaard similarity index by using the technique of terminal- restriction fragment length polymorphism after the aqueous extracts of six materials were orally administrated into rats for one month. Results : The results showed that the aqueous extracts of six materials had different effects on Lactobaciili in rat colon,but presented to inhibit them in rectum. However, all of these extracts enhanced the diversity and distribution evenness of Lactobacilli in colon except for that of Syzygium aromatieum and Foeniculum vulg are Mill. Foeniculum vulgare Mill reduced the diversity and distribution evenness of Lactobacilli in rectum. Conclusion : These extracts exerted a heavy impact on the composition of Lactobacilli in both colon and rectum. The functional mechanism of these materials on the dysfunction of digestive system might be relative with the shared and different effects on gut Lactobacilli.%目的:观察肉桂、干姜、丁香、小茴香、胡椒和花椒等六种香辛料水提取物对消化系统功能紊乱的积极作用.方法:本研究采用末端限制性片段长度多态性分析技术,再用总峰面积、Ribotype丰富度(S)、Shannon多样性指数(H)、均匀度指数(E)以及Jacaard相似性指数等指标,针对六种常见香辛料的水提取物对大鼠结肠和直肠中乳酸菌群的数量、多样性及结构进行了分析. 结果:六种香辛料的水提取物对结肠中乳酸菌群生长的影响存在差异,但均抑制了直肠中乳酸菌的生长;然

    The exposure to ultraviolet radiations (UVR) is the key source of skin sunburn; it may produce harmful entities, reactive oxygen species (ROS), leading to aging. The skin can be treated and protected from the injurious effects of ROS by using various pharmaceutical formulations, such as cream. Cream can be loaded with antioxidants to quench ROS leading to photo-protective effects. Moreover, modern medicines depend on ethnobotanicals for protection or treatment of human diseases. This review article summarizes various in vivo antioxidant studies on herbal creams loaded with phyto-extracts. These formulations may serve as cosmeceuticals to protect skin against injurious effects of UVR. The botanicals studied for dermatologic use in cream form include Acacia nilotica, Benincasa hispida, Calendula officinalis, Camellia sinensis, Camellia sinensis, Nelumbo nucifera, Capparis decidua, Castanea sativa, Coffea arabica, Crocus sativus, Emblica officinalis Gaertn, Foeniculum vulgare, Hippophae rhamnoides, Lithospermum erythrorhizon, Malus domestica, Matricaria chamomilla L., Moringa oleifera, Morus alba, Ocimum basilicum, Oryza sativa, Polygonum minus, Punica granatum, Silybum marianum, Tagetes erecta Linn., Terminalia chebula, Trigonella foenum-graecum, and Vitis vinifera. The observed anti-aging effects of cream formulations could be an outcome of a coordinating action of multiple constituents. Of numerous botanicals, the phenolic acids and flavonoids appear effective against UVR-induced damage; however the evidence-based studies for their anti-aging effects are still needed. PMID:26448818

    Full Text Available One hundred and eighty 7-week-old laying quail were fed various diets over a 12-week period. The diets included a control diet (without essential oil mixture (EOM or antibiotics (ANTs, a basal diet including EOM (24 mg/kg feed, and a basal diet including an ANT (avilamycin, 10 mg/kg feed. Each treatment comprised 4 replications with 4 cages (15 quail per cage, amounting to 60 quail per treatment group. Diets (in mash form and water were provided for ad libitum consumption. EOM consisted of 6 different essential oils derived from the following herbs: oregano (Origanum sp., laurel leaf (Laurus nobilis L., sage leaf (Salvia triloba L., myrtle leaf (Myrtus communis, fennel seeds (Foeniculum vulgare, and citrus peel (Citrus sp.. In comparison with the control diet, adding supplements such as EOM and ANTs to the basal diet increased egg production in quail (P<0.001. However, egg production was similar between EOM and ANT treatment groups. Moreover, there were no differences between the treatment groups with regard to egg weight. Feed intake was not affected by EOM or ANT supplementation, whereas feed conversion ratio was significantly improved by EOM and ANT supplementation. Thus, we concluded that EOM has beneficial effects as a dietary supplement on egg production and feed conversion ratio.

    Fennel (Foeniculum vulgare Mill.) mature fruit (commonly known as seeds) and essential oil of fennel are widely used as flavoring agents in food products such as liqueurs, bread, cheese, and an ingredient of cosmetics and pharmaceutical products. Moreover fennel infusions are the classical decoction for nursing babies to prevent flatulence and colic spasm. Traditionally in Europe and Mediterranean areas fennel is used as antispasmodic, diuretic, anti-inflammatory, analgesic, secretomotor, secretolytic, galactagogue, eye lotion, and antioxidant remedy and integrator. Topically, fennel powder is used as a poultice for snake bites. In Asian cultures fennel was ingested to speed the elimination of poisons. As one of the ancient Saxon people's nine sacred herbs, fennel was credited with the power to cure. Fennel was also valued as a magic herb: in the Middle Ages it was draped over doorways on Midsummer's Eve to protect the household from evil spirits. Recently because of estragole carcinogenicity, fennel has been charged to be dangerous for humans especially if used as decoction for babies. But this allegation do not consider the remedy is prepared as a matrix of substances, and recent researches confirm that pure estragole is inactivated by many substance contained in the decoction.

    Full Text Available Amenorrhea is described as complete absence or cessation of menstruation. Besides conventional treatment approaches, traditional and complementary medical systems have suggested numerous natural medications for management of amenorrhea. Current study aimed to compile the pharmacological reports on amenorrhea from the standpoints of early Persian scholars. Medical and pharmaceutical manuscripts of Persian medicine from 9th to 18th centuries A.D. have been reviewed to extract the critical points and natural remedies. Based on Traditional Persian Medicine (TPM, impairment in uterus, brain and circulation are main causes of amenorrhea. Any obstruction, either anatomical or functional, in uterus and allied organs or tissues may lead the body to this disorder. Concerning herbal therapy of amenorrhea in TPM, 71 medicinal plants related to 35 families were found. The most prevalent families were Apiaceae, Asteraceae, Lamiaceae and Fabaceae, respectively. Usual routes of administration were oral, vaginal and topical. However, there was one report on a medicament, spoken to be effective nasally. Traditionally, emmenagogue medicines should possess diuretic activity to be effective for amenorrhea. All reported remedies were known as diuretic agents. However, this description is not corresponded with what is now accepted as diuretic. On the other hand, only Foeniculum vulgare showed therapeutic effects on amenorrhea in a randomized placebo-controlled trial. Despite lack of novel information on emmenagogue activity of these remedies, design and conducting evidence-based animal or human studies may be beneficial for new drug discovery from traditional knowledge.

    Laūq is a pharmaceutical dosage form that had been mainly used for the treatment of various respiratory disorders in traditional Persian medicine. It is important from 2 aspects: a dosage form with efficient and optimum delivery of drugs to the respiratory tract and biological effects of its ingredients. Natural medicine in laūq has been demonstrated to act in respiratory disorders by their antitussive, antiallergic, anti-inflammatory, antioxidant, spasmolytic, and antibacterial activities. Some of these natural remedies act by most of the mentioned mechanisms such as Cydonia oblonga, Glycyrrhiza glabra, Crocus sativus, Hyssopus officinalis, Foeniculum vulgare, and honey. However, the evidence is limited including Cassia fistula, Papaver somniferum, and Drimia maritima. According to positive pharmacokinetic and pharmacodynamic aspects of laūqs, they may be considered as efficient dosage forms for delivery of drugs to the respiratory tract. For better compatibility of patients, it could be substituted laūqs with newer drug delivery systems like lozenges. PMID:26008751

    Full Text Available The antifungal activity of essential oils of fennel (Foeniculum vulgare Mill., Apiaceae, ginger (Zingiber officinale Roscoe, Zingiberaceae, mint (Mentha piperita L., Lamiaceae and thyme (Thymus vulgaris L., Lamiaceae was evaluated against mycotoxin producers Aspergillus flavus and A. parasiticus. High Resolution Gas Chromatography was applied to analyze chemical constituents of essential oils. The effect of different concentrations of essential oils was determined by solid medium diffusion assay. Mycelial growth and sporulation were determined for each essential oil at the concentrations established by solid medium diffusion assay. At the fifth, seventh and ninth days the mycelial diameter (Ø mm and spore production were also determined. FUN-1 staining was performed to assess cell viability after broth macrodilution assay. Trans-anethole, zingiberene, menthol and thymol are the major component of essential oils of fennel, ginger, mint and thyme, respectively. The effective concentrations for fennel, ginger, mint and thyme were 50, 80, 50 and 50% (oil/DMSO; v/v, respectively. The four essential oils analysed in this study showed antifungal effect. Additionally, FUN-1 staining showed to be a suitable method to evaluate cell viability of potential mycotoxigenic fungi A. flavus and A. parasiticus after treatment with essential oils.

    Herbal infusions and decoctions in water are some of the most commonly consumed beverages in the world. Although water is not a good solvent for many of the active components in herbs, liquid preparations are rich in several bioactive compounds. Most of them have powerful antioxidant activity and have been related to medicinal herbs' properties. Herein, decoctions and infusions in water of lemon-verbena (Aloysia citrodora) aerial parts and leaves, fennel (Foeniculum vulgare), pennyroyal (Mentha pulegium) and spearmint (Mentha spicata) aerial parts with different periods of storage (0, 30, 60 and 120 days), were prepared. The effects of the method of preparation and storage period on their antioxidant properties were analysed. For all the analysed species, infusions gave better results than the corresponding decoctions. Spearmint infusions showed the highest antioxidant properties, at all the storage periods, probably due to the highest levels and synergy between phenolics, flavonoids and ascorbic acid found in this sample. Linear discriminant analysis confirmed that the length of storage period has a significant influence on the antioxidant activity and antioxidant content. Flavonoids and reducing sugars proved to be the parameters that most highly contributed to cluster individual groups according to different periods of storage. PMID:20740475

    Infusions (herbal teas) and decoctions are used frequently to administer oral doses of herbs. Although some herbs are used as single ingredients, they are often prepared as mixtures, as reported by numerous ethnobotanical surveys. The present work was carried out to identify the different types of interaction (synergistic, additive and antagonistic effects) which may be found in the antioxidant activity of preparations from mixtures of the popular herbs Aloysia citrodora (lemon verbena), Foeniculum vulgare (fennel) and Mentha spicata (spearmint). Herbs were prepared using traditional methods, and the effects after different periods of storage, up to 120 days, were also evaluated. Antioxidant activity was evaluated using DPPH radical scavenging activity, reducing power and inhibition of lipid peroxidation by the β-carotene - linoleate system and the TBARS assay. Known antioxidant compounds such as total phenolics, flavonoids, ascorbic acid and reducing sugars were also determined. Spearmint was found to be present in the herb mixtures with the greatest antioxidant activity and these also had the highest flavonoid content. The most potent antioxidant activity was found in combinations of different herbs, suggesting synergistic effects. PMID:21308820

    Full Text Available An overview of the studies carried out in our laboratories on supercritical fluid extraction (SFE of volatile oils from seven aromatic plants: pennyroyal (Mentha pulegium L., fennel seeds (Foeniculum vulgare Mill., coriander (Coriandrum sativum L., savory (Satureja fruticosa Béguinot, winter savory (Satureja montana L., cotton lavender (Santolina chamaecyparisus and thyme (Thymus vulgaris, is presented. A flow apparatus with a 1 L extractor and two 0.27 L separators was built to perform studies at temperatures ranging from 298 to 353 K and pressures up to 30.0 MPa. The best compromise between yield and composition compared with hydrodistillation (HD was achieved selecting the optimum experimental conditions of extraction and fractionation. The major differences between HD and SFE oils is the presence of a small percentage of cuticular waxes and the relative amount of thymoquinone, an oxygenated monoterpene with important biological properties, which is present in the oils from thyme and winter savory. On the other hand, the modeling of our data on supercritical extraction of volatile oil from pennyroyal is discussed using Sovová’s models. These models have been applied successfully to the other volatile oil extractions. Furthermore, other experimental studies involving supercritical CO2 carried out in our laboratories are also mentioned.

    Full Text Available Twenty two plants were collected from Taif Governorate and identified as: Aerva lanata, Arnebia hispidissima, Artemisia judaica, Artemisia monosperma, Asphodelus aestives, Avena barbata, Capparis dcidua, Eucalyptus globulus, Euphorbia glomerifera, Foeniculum vulgare, Forsskaolea tenacissima, Juniperus procera, Launaea mucronata, Launaea sonchoides, Medicago sativa, Opuntia ficus, Phagnalon sinaicum, Prunus persica, Pulicaria crispa, Punica granatum, Rumex dentatus and Trichodesma calathiforme. Pathogenic fungi were isolated from some of these plants and identified as Alternaria alternata, Cephalosporium madurae, Cladosporium herbarum, Fusarium oxysporum, Humicola grisea, Penicillium chrysogenum and Ulocladium botrytis. Four antagonistic isolates were tested, 2 from Gliocladium fungus and 2 from Trichoderma fungus. We found that all the four antagonistic isolates (G. deliquescens, G. virens, T. viride and T. hamatum significantly inhibited the radial growth of the pathogenic fungi tested, with different ratios. The results indicated that the antibiotics produced by the antagonists were more effective than the fungus itself and differ with different fungi. Coating plant stems with antagonists or with antagonist extracts reduce the severity of the disease but not prevent it in all tested pathogens.

    Full Text Available The exposure to ultraviolet radiations (UVR is the key source of skin sunburn; it may produce harmful entities, reactive oxygen species (ROS, leading to aging. The skin can be treated and protected from the injurious effects of ROS by using various pharmaceutical formulations, such as cream. Cream can be loaded with antioxidants to quench ROS leading to photo-protective effects. Moreover, modern medicines depend on ethnobotanicals for protection or treatment of human diseases. This review article summarizes various in vivo antioxidant studies on herbal creams loaded with phyto-extracts. These formulations may serve as cosmeceuticals to protect skin against injurious effects of UVR. The botanicals studied for dermatologic use in cream form include Acacia nilotica, Benincasa hispida, Calendula officinalis, Camellia sinensis, Camellia sinensis, Nelumbo nucifera, Capparis decidua, Castanea sativa, Coffea arabica, Crocus sativus, Emblica officinalis Gaertn, Foeniculum vulgare, Hippophae rhamnoides, Lithospermum erythrorhizon, Malus domestica, Matricaria chamomilla L., Moringa oleifera, Morus alba, Ocimum basilicum, Oryza sativa, Polygonum minus, Punica granatum, Silybum marianum, Tagetes erecta Linn., Terminalia chebula, Trigonella foenum-graecum, and Vitis vinifera. The observed anti-aging effects of cream formulations could be an outcome of a coordinating action of multiple constituents. Of numerous botanicals, the phenolic acids and flavonoids appear effective against UVR-induced damage; however the evidence-based studies for their anti-aging effects are still needed.

    One hundred and eighty 7-week-old laying quail were fed various diets over a 12-week period. The diets included a control diet (without essential oil mixture (EOM) or antibiotics (ANTs)), a basal diet including EOM (24 mg/kg feed), and a basal diet including an ANT (avilamycin, 10 mg/kg feed). Each treatment comprised 4 replications with 4 cages (15 quail per cage), amounting to 60 quail per treatment group. Diets (in mash form) and water were provided for ad libitum consumption. EOM consisted of 6 different essential oils derived from the following herbs: oregano (Origanum sp.), laurel leaf (Laurus nobilis L.), sage leaf (Salvia triloba L.), myrtle leaf (Myrtus communis), fennel seeds (Foeniculum vulgare), and citrus peel (Citrus sp.). In comparison with the control diet, adding supplements such as EOM and ANTs to the basal diet increased egg production in quail (P < 0.001). However, egg production was similar between EOM and ANT treatment groups. Moreover, there were no differences between the treatment groups with regard to egg weight. Feed intake was not affected by EOM or ANT supplementation, whereas feed conversion ratio was significantly improved by EOM and ANT supplementation. Thus, we concluded that EOM has beneficial effects as a dietary supplement on egg production and feed conversion ratio. PMID:24587729

    Campylobacter jejuni is one of the most common bacterial causes of diarrhoea in the industrialized world, being associated with the occurrence of Guillain-Barré Syndrome, and inducing diseases partially through intestinal adherence. With increasing reports of C. jejuni drug resistance against standard antibiotics, investigations into antiadhesive agents for the prevention of bacterial infection are highly significant. Given the consumer-driven development towards holistic and integrative healthcare, research into additional anti-Campylobacter effects of herbal medicines that are already used for their beneficial effects on bowel and digestive functions is important. Twenty-one herbal extracts were screened for antiadhesive activity against C. jejuni using modifications of previously published antiadhesion assays. Antiadhesion effects with IC(50) values 35 mg/mL) was found for Agrimonia eupatoria (agrimony), Andrographis paniculata (andrographis), Matricaria recutita (chamomile), Foeniculum vulgare (fennel), Filipendula ulmaria (meadowsweet) and Artemisia absinthium (wormwood) extracts. This study provides evidence for additional beneficial effects of marketed herbal medicines in gastrointestinal disorders. PMID:21280113

    The prevalence of gastric diseases is increasing with H. pylori, the causative agent of acute and chronic gastritis, being a major predisposing factor for peptic ulcer disease and gastric carcinoma. C. jejuni is the most common cause of enteric infections, particularly among children, resulting in severe diarrhoea. Increasing drug resistance of these bacteria against standard antibiotics, and the more widespread use of herbal medicines, favours investigations into additional anti-Helicobacter and anti-Campylobacter effects of phytotherapeutics that are already used for their beneficial effects on bowel and digestive functions. Twenty-one hydroethanol herbal extracts and four essential oils were screened for antibacterial activity using a modification of a previously described micro-dilution assay and compared with the inhibitory effects of antibiotics. The herbal extracts showing the highest growth inhibition of C. jejuni were Calendula officinalis, Matricaria recutita, Zingiber officinale, Salvia officinalis, Foeniculum vulgare and Silybum marianum. Agrimonia eupatoria, Hydrastis canadensis, Filipendula ulmaria and Salvia officinalis were the most active herbal extracts in inhibiting the growth of H. pylori. This study provides evidence for additional beneficial effects of phytotherapeutics marketed for their gastrointestinal effects and identifies new beneficial antibacterial effects for some herbal medicines not currently recommended for gastrointestinal problems.

    Several studies have shown that manipulating flowering weeds within an agroecosystem can have an important role in pest control by natural enemies, by providing them nectar and pollen, which are significant sources of nutrition for adults. The aim of this study was to assess if the olive moth, Prays oleae (Bernard, 1788) (Lepidoptera: Praydidae), and five of its main natural enemies, the parasitoid species Chelonus elaeaphilus Silvestri (Hymenoptera: Braconidae), Apanteles xanthostigma (Haliday) (Hymenoptera: Braconidae), Ageniaspis fuscicollis (Dalman) (Hymenoptera: Encyrtidae) and Elasmus flabellatus (Fonscolombe) (Hymenoptera: Eulophidae), as well as the predator Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae), can theoretically access the nectar from 21 flowering weeds that naturally occur in olive groves. Thus, the architecture of the flowers as well as the mouthpart structure and/or the head and thorax width of the pest and its enemies were analyzed. The results suggested that all beneficial insects were able to reach nectar of the plant species from Apiaceae family, i.e. Conopodium majus (Gouan) Loret, Daucus carota L. and Foeniculum vulgare Mill., as well as Asparagus acutifolius L., Echium plantagineum L., Capsella bursa-pastoris (L.)

    Full Text Available An experiment was conducted to induce tetraploidy in three diploid barley varieties (Martin, Rihane and Manel through different colchicines treatments. Colchicine was added for three different concentrations at three different stages of plant development i.e. on seed (0.05% for 48 hours, on pre-germinated seeds (0.1% for 2 hours and on three leaf stage (0.1% for 16 hours. Colchicine application reduced significantly germination percentage and viability of plants. Seed germination was completely inhibited in Martin, while a reduction of 20% and 30% for germination percentage compared to control was recorded in varieties Manel and Rihane, respectively at 0.1% colchicine concentration. Ploidy evaluation showed no tetraploidy in all the three tested varieties by colchicine application of 0.05% for 48 hours on seeds and 0.1% for 2 hours on pre-germinated seeds. However, tetraploid plants were produced only by treatment with 0.1% for 16 hours of seedlings. The percentages of plants were 40%, 44% and 100% for Rihane, Manel and Martin, respectively. Cytological analyses showed the increase of chromosome numbers from 2n=2x=14 to 2n=4x=28. The increase of ploidy levels caused major changes in some morphological traits. In fact, the induced tetraploids in barley was accompanied by significant (P<0.01 decrease in plant height, tiller height, leaf number and leaf length compared to diploid control plants. colchicine treatment induce successfully the production of tetraploid barley plants and could be used in breeding programs.

    2009-01-01

    Full Text Available The presence of two maternal chromosome sets in triploid barley endosperm allows the distinction of maternal and paternal hordein bands in an electrophoregram: the maternal bands are stronger due to the higher gene dose. In the F1 generation there are differences between reciprocal crosses and in the F2 generation all 16 classes that are theoretically possible for a pair of polymorphic loci can be distinguished. This full classification is rarely possible in genetic studies, and allows more accurate estimates of recombination rates. Two hordein gene clusters (Hor1 and Hor2, corresponding to hordein C and hordein B respectively were analyzed in hybrids obtained by crossing two winter barley cultivars Partizan and HWV-247. Hordein separation was performed by acid-polyacrylamide gel electrophoresis at pH 3.2 (A-PAGE. A set of most informative bands of B and C hordeins was selected in each cross by two criteria: (1 presence or absence of bands in the parents and (2 signal strength to allow doses scoring. The average genetic distance between Hor1 and Hor2 loci was 11 cM. Distances in male and female maps were not significantly different, suggesting a similar recombination rate in male and female meiosis.

    Starch gel electrophoresis has been used to study the polymorphism of hordeins encoded by the Hrd A, Hrd B, and Hrd F loci in 93 landrace specimens of barley assigned to 17 ancient provinces located in modem Turkey. Forty-five alleles of Hrd A with frequencies of 0.11-29.34%, 51 alleles of Hrd B with frequencies of 0.11-8.07%, and 5 alleles of Hrd F with frequencies of 0.75-41.29% have been detected. Cluster analysis of the matrix of allele frequencies has demonstrated that barley populations from different old provinces of Turkey are similar to one another. Cluster structure of local barley populations has been found, most populations (82%) falling into three clusters. The first cluster comprises barley populations from six provinces (Thracia, Bithynia, Pontus, Lydia, Cappadocia, and Armenia); the second cluster, populations from five provinces (Paphlagonia, Galatia, Lycaonia, Cilicia, and Mesopotamia); and the third one, populations from three provinces (Phrygia, Karia, and Lycia). Barley populations from Mysia, Pamphlya, and Syria do not fall in any cluster. PMID:18186193

    International Nuclear Information System (INIS)

    A system of high-volume wheat and barley plant breeding from somatic cells cultivated in vitro is developed. The frequency of morphogenetic cell line formation is a very important factor characterizing the morphogenetic properties of plants, introduced in the culture in vitro. This value reflects the possibility of regeneration of a certain number of plants in vitro. Statistic analysis of the cell line induction frequencies and frequencies of morphogenetic line occurrence shows, that both processes are explained genetically. The data exist which point to increasing morphological potentials of cell cultures after irradiation with certain radiation doses

    Rust pathogens within the genus Puccinia cause some of the most economically significant diseases of crops. Different formae speciales of P. graminis have co-evolved to mainly infect specific grass hosts; however, some genotypes of other closely related cereals can also be infected. This study investigated the inheritance of resistance to three diverse pathotypes of the oat stem rust pathogen (P. graminis f. sp. avenae) in the 'Yerong' ✕ 'Franklin' (Y/F) barley doubled haploid (DH) population, a host with which it is not normally associated. Both parents, 'Yerong' and 'Franklin', were immune to all P. graminis f. sp. avenae pathotypes; however. there was transgressive segregation within the Y/F population, in which infection types (IT) ranged from complete immunity to mesothetic susceptibility, suggesting the presence of heritable resistance. Both QTL and marker-trait association (MTA) analysis was performed on the Y/F population to map resistance loci in response to P. graminis f. sp. avenae. QTL on chromosome 1H ('Yerong' Rpga1 and Rpga2) were identified using all forms of analysis, while QTL detected on 5H ('Franklin' Rpga3 and Rpga4) and 7H (Rpga5) were only detected using MTA or composite interval mapping-single marker regression analysis respectively. Rpga1 to Rpga5 were effective in response to all P. graminis f. sp. avenae pathotypes used in this study, suggesting resistance is not pathotype specific. Rpga1 co-located to previously mapped QTL in the Y/F population for adult plant resistance to the barley leaf scald pathogen (Rhynchosporium secalis) on chromosome 1H. Histological evidence suggests that the resistance observed within parental and immune DH lines in the population was prehaustorial and caused by callose deposition within the walls of the mesophyll cells, preventing hyphal penetration.

    A pot experiment was conducted to study the uptake of 137Cs by wheat grown in five representative soils of Bangladesh having different soil characteristics. Artificial application of 137Cs increased the activity in soils up to 45.9 Bq/kg soil, measured at the end of the harvest of wheat crop. Different plant parts had different ability to accumulate 137Cs. Grains had the least activity and transfer factor, while the highest activity and lowest transfer factor were measured in roots, which restricted translocation of 137Cs to wheat straw. The result showed that the transfer factors (mean value) varied from 0.05 to 0.114 in wheat straw, 0.066-0.133 in roots and 0.011-0.043 in wheat grains. The activity and transfer factor of radioactive cesium in wheat plants were found to be greatly influenced by soil properties, i.e. clay content, K, organic matter, CEC, pH, exchangeable ions, etc. Cation exchange capacity and calcium in soils influenced positively, while clay minerals, exchangeable K and organic matter, negatively affected the 137Cs activity concentrations in wheat plants.

    Full Text Available INTRODUCTION: Salinity and waterlogging are two major abiotic stresses severely limiting barley production. The lack of a reliable screening method makes it very hard to improve the tolerance through breeding programs. METHODS: This work used 188 DH lines from a cross between a Chinese landrace variety, TX9425 (waterlogging and salinity tolerant, and a Japanese malting barley, Naso Nijo (waterlogging and salinity sensitive, to identify QTLs associated with the tolerance. RESULTS: Four QTLs were found for waterlogging tolerance. The salinity tolerance was evaluated with both a hydroponic system and in potting mixture. In the trial with potting mixture, only one major QTL was identified to associate with salinity tolerance. This QTL explained nearly 50% of the phenotypic variation, which makes it possible for further fine mapping and cloning of the gene. This QTL was also identified in the hydroponic experiment for different salt-related traits. The position of this QTL was located at a similar position to one of the major QTLs for waterlogging tolerance, indicating the possibility of similar mechanisms controlling both waterlogging and salinity tolerance. CONCLUSION: The markers associated with the QTL provided a unique opportunity in breeding programs for selection of salinity and waterlogging tolerance.

    Elevated atmospheric CO2 treatments stimulated biomass production in Fe-sufficient and Fe-deficient barley plants, both in hydroponics and in soil culture. Root/shoot biomass ratio was increased in severely Fe-deficient plants grown in hydroponics but not under moderate Fe limitation in soil culture. Significantly increased biomass production in high CO2 treatments, even under severe Fe deficiency in hydroponic culture, indicates an improved internal Fe utilization. Iron deficiency-induced secretion of PS in 0.5 to 2.5 cm sub-apical root zones was increased by 74% in response to elevated CO2 treatments of barley plants in hydroponics but no PS were detectable in root exudates collected from soil-grown plants. This may be attributed to suppression of PS release by internal Fe concentrations above the critical level for Fe deficiency, determined at final harvest for soil-grown barley plants, even without additional Fe supply. However, extremely low concentrations of easily plant-available Fe in the investigated soil and low Fe seed reserves suggest a contribution of PS-mediated Fe mobilization from sparingly soluble Fe sources to Fe acquisition of the soil-grown barley plants during the preceding culture period. Higher Fe contents in shoots (+52%) of plants grown in soil culture without Fe supply under elevated atmospheric CO2 concentrations may indicate an increased efficiency for Fe acquisition. No significant influence on diversity and function of rhizosphere-bacterial communities was detectable in the outer rhizosphere soil (0-3 mm distance from the root surface) by DGGE of 16S rRNA gene fragments and analysis of marker enzyme activities for C-, N-, and P-cycles.

    Full Text Available The amplified fragment length polymorphism (AFLP assay is an efficient method for the identification of molecular markers, useful in the improvement of numerous crop species. Bulked Segregant Analysis (BSA was used to identify AFLP markers associated with water-stress tolerance in barley, as this would permit rapid selection of water-stress tolerant genotypes in breeding programs. AFLP markers linked to water-stress tolerance was identified in two DNA pools (tolerant and sensitive, which were established using selected F2 individuals resulting from a cross between water-stress-tolerant and sensitive barley parental genotypes, based on their paraquat (PQ tolerance, leaf size, and relative water content (RWC. All these three traits were previously shown to be associated with water-stress tolerance in segregating F2 progeny of the barley cross used in a previous study. AFLP analysis was then performed on these DNA pools, using 40 primer pairs to detect AFLP fragments that are present/absent, respectively, in the two pools and their parental lines. One separate AFLP fragment, which was present in the tolerant parent and in the tolerant bulk, but absent in the sensitive parent and in the sensitive bulk, was identified. Polymorphism of the AFLP marker was tested among tolerant and sensitive F2 individuals. The presence of this marker that is associated with water-stress tolerance will greatly enhance selection for paraquat and water-stress tolerant genotypes in future breeding programs.

    The effect of microgravitation (simulated by clinorotation) on the organization and functioning of chloroplasts, isolated from barley plants, is studied with the use SDS-electrophoresis, spectrophotometric and polarography methods. The relative content of monomeric forms of light harvesting complex of photosystem II (LHCII) increases at the expense of its oligomeric forms under clinorotation conditions. The decrease of the portion of the entire complex of photosystem I (PSI) as well as of the sum of the PSI complexes and the complex CPa (related to PSII) was observed in experimental variants. Clinorotation induced the decrease in PSI, PSII and full electron transport activity, and the extent of the reduction depended on the light intensity during plant growth. The ATP synthesis coupled with cyclic, noncyclic and linear electron transport was inhibited under the simulated microgravitation.

  9. Diversity for seedling vigor in wild barley (hordeum vulgare L. subs. simpatina) germplasm

    International Nuclear Information System (INIS)

    Seedling vigor is important for improving stand establishment of barley crops, particularly in arid regions and areas where the soil temperature is low at sowing time. Three hundred and fifteen wild barley accessions from the Wild Barley Diversity Collection (WBDC) were evaluated for nine seedling vigor traits in a poly house and growth chamber under hydroponic conditions. The accessions exhibited significant differences for all traits investigated. Traits showing greatest phenotypic variation were seedling visual score, plant height, shoot fresh weight, shoot dry weight and shoot length. Seed weight exhibited the least variation. Seed weight was significantly correlated with visual seedling score and shoot and seedling fresh and dry weight. Correlation analysis showed that the visual seedling score was a reliable method for estimating seedling vigor in wild barley. The first three principal components (PC) explained 82.3% of the variation present in the WBDC with PC1(54.0%) associated with shoot fresh weight, shoot dry weight, seedling dry weight, seedling fresh weight, shoot length and seedling length. Accessions from the southwest portion of the Fertile Crescent, like WBDC020 (Turkey), WBDC238 (Jordan) and WBDC244 (Jordan) exhibited the highest positive values for most of the plant vigor traits investigated. These wild barley accessions likely carry alleles that will be useful for the improvement of plant vigor traits in cultivated barley. (author)

  10. Effect of nitrogen application on yield and yield components of barley (hordeum vulgare l.)

    International Nuclear Information System (INIS)

    The present research was aimed to study the effect of different levels of inorganic fertilizer N on the yield and yield components of barley varieties at KPK Agricultural University, Peshawar, Pakistan. The experiment was laid out in randomized complete block design with split plot arrangements. Barley varieties (local and sterling) were sown in the main plots whereas different nitrogen levels (i.e. 0, 20, 40, 60, 80 and 100 kg ha/sup -1/) were allotted to sub-plots. The results showed that different varieties and nitrogen levels had significantly (p<0.05) affected plant height, 1000 grains weight, grains spike/sup -1/, straw yield, grain yield, biological yield, grain and plant N. Maximum grain spike/sup -1/ , thousand grain weight and grain yield was recorded in sterling. Taller plants, highest biological yield, straw yield, grain and plant N was observed in local variety. Nitrogen applied at the rate of 60 kg ha/sup -1/ resulted in maximum grain spike/sup -1/, thousand grain weight, biological yield, grain yield, grain and plant N. (author)

  11. Effect of low doses of gamma radiation on barley's (Hordeum Vulgare L.) susceptibility to cochliobolus sativus

    International Nuclear Information System (INIS)

    Two barley genotypes (Tadmor, W12291), and one promising line selected in AECS (76) were exposed to 60 cobalt gamma radiation. The doses used were: 0, 10, 15, 20, 30, 40 and 50 Gy. Susceptibility assessments were scored using a rating scale extending from 1 (highly resistant) to 5 (very susceptible) according to the percentage of infected area at subcrown interodes. In general, doses of 10, 15, 20 and 30 Gy increased the resistance to the pathogen Cochliobolus sativus by 56.29%, 58.29%, 54.57% and 49.71% respectively. The genotypes did not response similarly to the irradiation. The best response was obtained with c.v Tadmor. (author)

    Yield, 1000 grain weight and other agronomical traits were studied under the rain fed condition. Nineteen pure lines (doubled haploid) and mutants and two controls were grown in the field. Net blotch resistance in 150 (Dh), mutants, and their parental genotype were used to determine their resistance level against three strains of net bloch. Differences were found among the genotypes. Five lines (Dh) and mutants resistant to net blotch with good agronomic performance were selected for further investigation. (author)

  13. Durable resistance to net blotch and agronomic performance in some barley mutants [Hordeum vulgare L.; Syria

    International Nuclear Information System (INIS)

    Seeds from the net blotch (Pyrenophora teres) susceptible cultivar Thibaut were treated by gamma ray radiation and subsequently evaluated for reaction to the pathogen in the M2-M5 generations. Grain yield and agronomic characteristics of putative mutants were compared with Thibaut in two different locations. Genetic variation among some mutant lines/cv Thibaut was estimated using Amplified Fragment Length Polymorphism (AFLP) markers. Sixteen mutant lines and their mother cultivar Thibaut were analyzed with 14 EcoR1-Mse1 primer combinations. A total number of 504 AFLP bands were analyzed for each pair mutant/Thibaut. Narrow genetic variation among all genotypes was detected with an average of genetic similarity of 0.96. Cluster analysis with the entire AFLP data divided all genotypes into two major groups. The resistant mutant lines were grouped in one subcluster with 0.98 similarity index. Some resistant mutant lines to net blotch with good agronomic performances were produced

  14. Study of variation in radiosensitivity of barley (Hardeum Vulgare) as a function of seed water content

    International Nuclear Information System (INIS)

    The study of the sorption curve representing the development of water content versus relative humidity, in barley seeds (CV. Thibaut), shows that water is present in three different states: Constitutive water at less than 8.1%, absorption water between 8.1 and 10.9%, and free water at more than 10.9%. Along with these states, radiosensitivity is respectively high, low, and high. The seeds detached from the rachis have less radioresistance than the attached ones. However, this difference in behaviour is reduced when the water content is high (presence of free water). We also observed that growth was stimulated by weak doses of irradiation (20 Gy), whatever the water content was. (author). 35 refs., 4 figs., 1 tab

  15. The effect of irradiating barley seeds (Hordeum Vulgare) on plantlet growth and net blotch resistance

    International Nuclear Information System (INIS)

    Barley seeds of two cultivars (Smash and Thibaut) and one line (74-F-6) with water contents adjusted between 12.8 and 13.3%, were irradiated with various doses (1-sup 1 sup 6 sup 0 Gy) of sup 6 sup 0 Co γ rays. Doses of 1-sup 4 sup 0 Gy favored an increases length of the first leaf. In general, doses of 15 and sup 2 sup 0 Gy decreased barley susceptibility to Drechrlera teres f. maculata by 25 and 21%, respectively. This reduction was a function of the line or cultivar used. The best response was obtained with cv. Smash. Seedling growth stimulation and host susceptibility to D. teres were significantly correlated (r= -0.68). The stimulatory effect of γ rays on growth could be used at low levels, to provide adequate field resistance to net blotch caused by D. teres f. maculata. (author). 28 refs., 3 tabs

    This paper provides a rejoinder to Colander, Holt and Rosser (2010) strategy to win friends and influence mainstream economics. It is suggested that their strategy is counter-productive, and while it might gain them friends, it will not lead to increased influence of heterodox ideas within what they term the cutting edge of the profession. It is argued that their failure to understand the nature of heterodoxy, and the reason for the eclecticism of the mainstream, associated to the rise of vul...

    During germination of barley seeds, mobilization of protein is essential and cysteine proteases accounts for more than 90 % of the total proteolytic activity in the degradation of barley seed storage proteins. Cysteine proteases exist as pro-enzyme and is activated through reduction of the active...... site cysteines and by removal of the pro-domain. The complement of cysteine proteases is comprehensive and for detailed studies of the individual components of this complement, a fast and efficient eukaryotic expression platform is highly desirable.

    In order to preserve environmental quality, alternative strategies to chemical-intensive agriculture are strongly needed. In this study, we characterized in vitro the potential plant growth promoting (PGP) properties of a gamma-proteobacterium, named MIMR1, originally isolated from apple shoots in micropropagation. The analysis of the 16S rRNA gene sequence allowed the taxonomic identification of MIMR1 as Luteibacter rhizovicinus. The PGP properties of MIMR1 were compared to Pseudomonas chlororaphis subsp. aurantiaca DSM 19603(T), which was selected as a reference PGP bacterium. By means of in vitro experiments, we showed that L. rhizovicinus MIMR1 and P. chlororaphis DSM 19603(T) have the ability to produce molecules able to chelate ferric ions and solubilize monocalcium phosphate. On the contrary, both strains were apparently unable to solubilize tricalcium phosphate. Furthermore, the ability to produce 3-indol acetic acid by MIMR1 was approximately three times higher than that of DSM 19603(T). By using fluorescent recombinants of strains MIMR1 and DSM 19603(T), we also demonstrated that both bacteria are able to abundantly proliferate and colonize the barley rhizosphere, preferentially localizing on root tips and in the rhizoplane. Finally, we observed a negative effect of DSM 19603(T) on barley seed germination and plant growth, whereas MIMR1, compared to the control, determined a significant increase of the weight of aerial part (+22 %), and the weight and length of roots (+53 and +32 %, respectively). The results obtained in this work make L. rhizovicinus MIMR1 a good candidate for possible use in the formulation of bio-fertilizers. PMID:23653264

Whenever a translator is confronted with swearing expressions he is faced with the dilemma of what exactly to do, because there is no possibility to look up such expressions in a bilingual dictionary. He has to rely on himself and in the process the translation may become a subjective piece of work resulting in a certain deviation from the original. Furthermore, swearw...
