    Berberine is an isoquinoline alkaloid present in several plants, including Coptis sp. and Berberis sp. Berberine is a customary component in Chinese medicine, and is characterized by a diversity of pharmacological effects. An extensive search in electronic databases (PubMed, Scopus, Ovid, Wiley, ProQuest, ISI, and Science Direct) were used to identify the pharmacological and clinical studies on Berberis vulgaris and berberine, during 2008 to 2015, using 'berberine' and 'Berberis vulgaris' as search words. We found more than 1200 new article studying the properties and clinical uses of berberine and B. vulgaris, for treating tumor, diabetes, cardiovascular disease, hyperlipidemia, inflammation, bacterial and viral infections, cerebral ischemia trauma, mental disease, Alzheimer disease, osteoporosis, and so on. In this article, we have updated the pharmacological effects of B. vulgaris and its active constituent, berberine. Copyright © 2016 John Wiley & Sons, Ltd.

    Full Text Available The genus Berberis (Berberidaceae includes about 500 species worldwide, some of which are widely cultivated in the north-eastern regions of Iran. This genus consists of spiny deciduous evergreen shrubs, characterized by yellow wood and flowers. The cultivation of seedless barberry in South Khorasan goes back to two hundred years ago. Medicinal properties for all parts of these plants have been reported, including: Antimicrobial, antiemetic, antipyretic, antioxidant, anti-inflammatory, anti-arrhythmic, sedative, anti-cholinergic, cholagogic, anti-leishmaniasis, and anti-malaria. The main compounds found in various species of Berberis, are berberine and berbamine. Phytochemical analysis of various species of this genus revealed the presence of alkaloids, tannins, phenolic compounds, sterols and triterpenes. Although there are some review articles on Berberis vulgaris (as the most applied species, there is no review on the phytochemical and pharmacological activities of other well-known species of the genus Berberis. For this reason, the present review mainly focused on the diverse secondary metabolites of various species of this genus and the considerable pharmacological and biological activities together with a concise story of the botany and cultivation.

    Full Text Available Premise of the study: Southern barberry or calafate (Berberis microphylla is a shrub species endemic to the Patagonian region of South America that is used for human consumption. The fruit is very rich in vitamin C and anthocyanins and has a very high antioxidant capacity. There have been only a few genetic studies of this and other closely related species. Methods and Results: Here we present the first 18 microsatellite markers of B. microphylla that were characterized using 66 accessions of calafate from Patagonia. On average, they had 7.6 alleles per marker, with an expected heterozygosity of 0.688. The informativeness of these markers was also evaluated in another 15 Berberis species, including most of the native and endemic Chilean species. Conclusions: The results confirm that these new simple sequence repeat markers are very polymorphic and potentially useful in genetic studies in any species of the genus Berberis.

    Background Bacterial vaginosis is one of the most prevalent complications among reproductive-aged women. Antibacterial and antifungal effects of Berberis vulgaris have been demonstrated in vitro and in vivo. Objectives This study aimed to compare the therapeutic effects of the vaginal gel of Berberis vulgaris 5% (in metronidazole base) with metronidazole vaginal gel 0.75% on bacterial vaginosis on 80 patients referred to the Hajar Hospital from January 2012 to April 2013. Methods This study was a randomized clinical trial research on 80 women affected by bacterial vaginosis, who were randomly divided into two groups of 40 participants. Diagnostic criteria were Amsel’s criteria and Gram stain. Berberis vulgaris 5% (in metronidazole gel base) or metronidazole vaginal gel for five-night usage was prescribed to each group, and after two to seven days therapeutic effects and Amsel criteria were assessed. Data analysis was performed by SPSS 16 using Student t-test, chi-square, and ANOVA tests. Results Findings of the study showed a statistically significant difference with regard to treatment response between the study groups (p<0.001), and the Berberis vulgaris group had a better response than the metronidazole gel group. The patients in groups of Berberis vulgaris in a metronidazole gel base did not experience any relapse, but, in the metronidazole group, 30% of patients experienced relapse during three weeks’ follow-up. Conclusions Findings of the study showed that adding Berberis vulgaris fruit extract on metronidazole improve the efficacy of bacterial vaginosis therapy. Clinical trial registration The trial was registered at the Iranian Registry of Clinical Trials (http://www.irct.ir) with the IRCT ID: IRCT201411102085N13.

    Full Text Available Testing plant extracts for controlling fungal diseases is a main biocontrol method. More interesting is to see what happens to the fungus treated with the plant extract. Therefore, the aim of the study was to evaluate the antifungal activity of Berberis vulgaris extract on Botrytis cinerea and to examine the ultrastructural changes in B. cinerea conidia caused by the minimum inhibitory concentration (MIC, using SEM and TEM. The antifungal activity of B. vulgaris bark extract was investigated using agar dilution method, and compared to that of berberine. Fluconazole was used as the positive antimycotic control. It was found that (1 B. vulgaris bark extract had significant antifungal activity against B. cinerea, and its effect was stronger than that of pure berberine. It was also noted that (2B. vulgaris MIC caused severe structural changes of the conidia, comparable with berberine MIC effect; therefore (3 B. vulgaris bark extract might be recommended to be tested as a biocontrol agent against B. cinerea.

    Sribash Roy

    Full Text Available BACKGROUND: The concept of DNA barcoding for species identification has gained considerable momentum in animals because of fairly successful species identification using cytochrome oxidase I (COI. In plants, matK and rbcL have been proposed as standard barcodes. However, barcoding in complex genera is a challenging task. METHODOLOGY AND PRINCIPAL FINDINGS: We investigated the species discriminatory power of four reportedly most promising plant DNA barcoding loci (one from nuclear genome--ITS, and three from plastid genome--trnH-psbA, rbcL and matK in species of Indian Berberis L. (Berberidaceae and two other genera, Ficus L. (Moraceae and Gossypium L. (Malvaceae. Berberis species were delineated using morphological characters. These characters resulted in a well resolved species tree. Applying both nucleotide distance and nucleotide character-based approaches, we found that none of the loci, either singly or in combinations, could discriminate the species of Berberis. ITS resolved all the tested species of Ficus and Gossypium and trnH-psbA resolved 82% of the tested species in Ficus. The highly regarded matK and rbcL could not resolve all the species. Finally, we employed amplified fragment length polymorphism test in species of Berberis to determine their relationships. Using ten primer pair combinations in AFLP, the data demonstrated incomplete species resolution. Further, AFLP analysis showed that there was a tendency of the Berberis accessions to cluster according to their geographic origin rather than species affiliation. CONCLUSIONS/SIGNIFICANCE: We reconfirm the earlier reports that the concept of universal barcode in plants may not work in a number of genera. Our results also suggest that the matK and rbcL, recommended as universal barcode loci for plants, may not work in all the genera of land plants. Morphological, geographical and molecular data analyses of Indian species of Berberis suggest probable reticulate evolution and thus

    Full Text Available In order to evaluate the effect of Berberis vulgaris extract on the experimental ulcers of cutaneous leishmaniasis (CL on Balb/c mice, a study was undertaken over a 12 months period. Forty Balb/c mice were divided into 2 main groups A and B. Each main group in turn was divided into 5 sub groups of 4 mice and each sub group were inoculated subcutaneously by 0.1ml liquid phase culture containing promastigotes of Leishmania major. After 2-3 weeks, nodules and ulcers appeared on 37 of 40 inoculated mice. Ethanol extract of the stem and leaves as well as roots of Berberis vulgaris in different concentrations, were used topically on CL lesions of 4 sub groups A and B, respectively. Ethanol alone was used on the lesions of control mice. The surface area of lesions were measured before and 1-2 weeks after treatment. Direct Geimsa stained smear prepared 20 days after treatment. The results showed that after 2 weeks, a statistically significant decrease of ulcer size of treated mice observed, while in the control group the lesion growth continued. The examinations showed that using higher concentration of the extract caused more decrease in surface area of CL lesions on day 15 and negative direct smear on day 20. Alcoholic extract of B.vulgaris root was more effective than leaves and stem extract. Alcoholic extract of B vulgaris might be further used in animal model.

  11. Male function for ensuring pollination and reproductive success in Berberis lycium Royle: A novel mechanism

    Supriya Sharma; Verma Susheel

    2016-03-01

    In Berberis lycium anthers on alternate stamens dehisce, thus prolonging the male function so that pollination is affected and reproduction is ensured. The large pollen sac of each bithecous anther after the appearance of longitudinal dehiscence slit moves away from the filament while remaining attached at the tip of the connective and then orients in such a way that pollen-laden surface faces the stigma. No pollen is available to receptive stigma as pollen grains remain stuck to the anther sac. They do not get dispersed even by wind. Pollination and consequently reproduction is ensured through the intervention of insect, which does not affect pollen transfer to the stigma directly but by touching the base of the staminal filament while foraging nectar secreted by nectaries at the base of corolla, thus leading to staminal movement. This makes the dehisced anthers stick to the stigma and deposit pollen there.

    Predictive distribution modelling of Berberis aristata DC, a rare threatened plant with high medicinal values has been done with an aim to understand its potential distribution zones in Indian Himalayan region. Bioclimatic and topographic variables were used to develop the distribution model with the help of three different algorithms viz. Genetic Algorithm for Rule-set Production (GARP), Bioclim and Maximum entropy (MaxEnt). Maximum entropy has predicted wider potential distribution (10.36%) compared to GARP (4.63%) and Bioclim (2.44%). Validation confirms that these outputs are comparable to the present distribution pattern of the B. aristata. This exercise highlights that this species favours Western Himalaya. However, GARP and MaxEnt's prediction of Eastern Himalayan states (i. e. Arunachal Pradesh, Nagaland and Manipur) are also identified as potential occurrence places require further exploration.

    Many herbaceous plants contain compounds that have biological effects in addition to their medicinal properties. They have compounds with numerous properties, including hypo lipidemic, hypoglycemic, antioxidant, and hepato protective ones, which have been analyzed at different levels. One of these plants, with the scientific name of Berberis vulgaris, is barberry. The most important compounds identified in this plant are berberine, oxycontin, palmatine, bervulcine, berbamine, columbamine, jatrorrhizine, coptisine, and berbamine. In addition to alkaloids, organic acids such as chelidonic acid, citric acid, malic acid, resin, tannin, pectinic, and mucilagic substances are among the ingredients of barberry. In this paper, it was attempted to determine the role and effect of the extract of barberry on various body organs. The results showed that berberine actually increases insulin sensitivity and is capable of inhibiting alpha glucosidase, adipogenesis, and thus acts as an anti-obesity and hypoglycemic agent. Berberine reduces the density of serum cholesterol and triglycerides and can improve the function of liver enzymes, therefore, it can be suggested as a hypo lipidemic and hepato protective plant extract. The hepato protective effects of this extract are probably due to its antioxidant properties. Studies showed that barberry have numerous health benefits, including anti-inflammatory ones. Moreover, it can be used as a medicinal herb to treat a variety of disorders, such as diabetes, liver disease, gallbladder pain, digestive, urinary tract diseases, and gallstones. However, more studies on this issue and doing more focused and intensive researches in this field are recommended.

    High-pressure extraction and ultrasonification extraction techniques were employed to extract bioactive compounds from Berberis koreana. This study aimed to determine the effect of ultrasonification in a high pressure process on the extraction yield, and the anticancer and antioxidant activities of the B. koreana bark extract. The effect of high-pressure extraction time when carried out for 5 and 15 min (HP5 and HP15) was also investigated. The best extraction yield with maximum percentage of phenolic compounds was obtained using high pressure with sonification (HPWS) extraction method. Experimental results indicated that HPWS altered the antioxidant activities, including the scavenging capacity of diphenylpicrylhydrazyl (DPPH) and xanthine oxidase. HP5 and HP15 with conventional extraction have almost similar bioactivity, but showed lower antioxidant and anticancer activities compared to HPWS. The results showed that the application of ultrasonification improved the extraction efficiency for bioactive compounds and, as deduced from chromatographic profiles, it may have allowed the release of new compounds. The scanning electron microscope (SEM) showed evidence of rupturing of the tissue surface treated with HPWS, in contrast to conventional extraction, HP5, and HP15. The HPWS extraction was not only more efficient but also convenient for the recovery and purification of the active compounds of hard plant tissues.

    Background Berberine is an isoquinoline alkaloid widely used to improve the glucidic and lipidic profiles of patients with hypercholesterolemia, metabolic syndrome, and type 2 diabetes. The limitation of berberine seems to be its poor oral bioavailability, which is affected by the presence, in enterocytes, of P-glycoprotein – an active adenosine triphosphate (ATP)-consuming efflux protein that extrudes berberine into the intestinal lumen, thus limiting its absorption. According to some authors, silymarin, derived from Silybum marianum, could be considered a P-glycoprotein antagonist. Aim The study aimed to evaluate the role played by a possible P-glycoprotein antagonist (silymarin), when added to a product containing Berberis aristata extract, in terms of benefits to patients with type 2 diabetes. Methods The study enrolled 69 patients with type 2 diabetes in suboptimal glycemic control who were treated with diet, hypoglycemic drugs, and in cases of concomitant alterations of the lipid profile, hypolipidemic agents. The patients received an add-on therapy consisting of either a standardized extract of Berberis aristata (titrated in 85% berberine) corresponding to 1,000 mg/day of berberine, or Berberol®, a fixed combination containing the same standardized extract of Berberis aristata plus a standardized extract of Silybum marianum (titrated as >60% in silymarin), for a total intake of 1,000 mg/day of berberine and 210 mg/day of silymarin. Results Both treatments similarly improved fasting glucose, total cholesterol, low-density lipoprotein (LDL) cholesterol, triglyceride, and liver enzyme levels, whereas glycosylated hemoglobin (HbA1c) values were reduced to a greater extent by the fixed combination. Conclusion The association of berberine and silymarin demonstrated to be more effective than berberine alone in reducing HbA1c, when administered at the same dose and in the form of standardized extracts in type 2 diabetic patients.

    Full Text Available Cancer stem cells (CSCs, including those of advanced prostate cancer, are a suggested reason for tumor resistance toward conventional tumor therapy. Therefore, new therapeutic agents are urgently needed for targeting CSCs. Despite the minimal understanding of their modes of action, natural products and herbal therapies have been commonly used in the prevention and treatment of many cancers. Berberis libanotica Ehrenb (BLE is a plant rich in alkaloids which may possess anti-cancer activity and a high potential for eliminating CSCs. We tested the effect of BLE on prostate cancer cells and our data indicated that this extract induced significant reduction in cell viability and inhibited the proliferation of human prostate cancer cell lines (DU145, PC3 and 22Rv1 in a dose- and time-dependent manner. BLE extract induced a perturbation of the cell cycle, leading to a G0-G1 arrest. Furthermore, we noted 50% cell death, characterized by the production of high levels of reactive oxidative species (ROS. Inhibition of cellular migration and invasion was also achieved upon treatment with BLE extract, suggesting a role in inhibiting metastasis. Interestingly, BLE extract had a major effect on CSCs. Cells were grown in a 3D sphere-formation assay to enrich for a population of cancer stem/progenitor cells. Our results showed a significant reduction in sphere formation ability. Three rounds of treatment with BLE extract were sufficient to eradicate the self-renewal ability of highly resistant CSCs. In conclusion, our results suggest a high therapeutic potential of BLE extract in targeting prostate cancer and its CSCs.

    Bioassay-guided isolation and fractionation of Berberis jaeschkeana Schneid var. jaeschkeana stem resulted in the isolation and characterisation of a new long chain hydroxy ester named as berberinol (1) along with six known compounds (2-7). All the structures were established from 1D and 2D spectroscopic data. Crude extract, sub-fractions and all the isolated compounds were evaluated for their anti-fungal and urease enzyme inhibition properties. All of the sub-fractions and compounds showed good anti-fungal and urease enzyme inhibition properties. Minimum inhibitory concentrations (MICs) were calculated for all active samples in case of urease enzyme inhibition. MICs values were found to be in the range of 39.03-49.78 μg/mL for urease enzyme inhibition.

    Full Text Available Introduction This study was intended to evaluate the nutritional value, phenolic compounds and digestibility coefficients of barberry leaves. Berberis vulgaris is one of the major crops in the province. The province has more than 70 percent and 95 percent of the total area under cultivation of barberry. Waste and foliage of barberry harvest traditionally used to feed livestock Tannin concentration greater than 3 to 4 percent in food, can have negative effects on digestibility in ruminants and in particular to reduce the absorption of dietary protein. So it can be expected that high amounts of tannins within waste foliage of barberry reduce its efficiency in ruminants to be fed. Several studies have shown that the addition of certain compounds such as urea, polyethylene Due to the high volume of barberry foliage that remains after harvesting and the possibility of its use in animal nutrition, this study tried to determine some nutrient compounds, phenolic compounds and degradation parameters were barberry leaves. In addition, in this study to determine the best additives are effective in reducing the concentration of tannins and phenolic compounds, urea, polyethylene glycol, sodium hydroxide and calcium hydroxide were compared. Materials and method As the samples were dried by the sun for 6 days. The amount of 5% by weight (dry matter basis urea, polyethylene glycol, sodium hydroxide or calcium hydroxide that was prepared with distilled water, was sprayed on 5 kg of the sample and thoroughly mixed. Each of the treatments were prepared in triplicate. Treatments include: 1 control (foliage without additives, 2 foliage with 5% solution of urea, 3 foliage with 5% polyethylene glycol, 4 foliage with 5% sodium hydroxide, 5 with 5% calcium hydroxide was foliage. The sample were kept in anaerobic plastic containers for 3 days and then opened and dried at room temperature. Samples were analyzed for crude protein, neutral detergent fiber, acid detergent

    Full Text Available Diabetes mellitus is a complex endocrine disorder. There is a serious attempt to identify antidiabetic compounds from natural sources to use with other drugs for reduction of diabetes complications. Present study is based on the investigation of antihyperglycemic effect of anthocyanin fraction of Berberis integerrima Bunge (AFBI fruits on some physiological parameters (glucose level, glycogen content, and body weight in normal and streptozotocin-induced (STZ-induced diabetic rats and evaluation of synergic effect of this fraction with metformin and glibenclamide. Male Sprague dawley rats were divided into nine groups: healthy control group, diabetic control group, diabetic groups treated with anthocyanin fraction (200, 400 and 1000 mg/kg, respectively; diabetic groups treated with glibenclamide and metformin separately, diabetic groups treated with glibenclamide + anthocyanin fraction (1000 mg/kg, metformin + anthocyanin fraction (1000 mg/kg. Treatment of diabetic rats with AFBI (400, 1000mg/kg significantly decreased blood glucose as compared with control. Moreover, AFBI (400, 1000mg/kg significantly increased liver glycogen and body weight compared to control. Nevertheless, there were no synergistic effects between anthocyanin fraction and metformin or glibenclamide on blood glucose, liver glycogen, and body weight. The results of this study indicate that AFBI possesses hypoglycemic effects and may be considered for evaluation in future diabetes clinical studies.

    Full Text Available Berberis aetnensis C. Presl (Berberidaceae is a bushy-spiny shrub common on Mount Etna (Sicily. We demonstrated that the alkaloid extract of roots of B. aetnensis C. Presl contains prevalently berberine and berbamine, possesses antimicrobial properties, and was able to counteract the upregulation evoked by glutamate of tissue transglutaminase in primary rat astroglial cell cultures. Until now, there are no reports regarding antioxidant properties of B. aetnensis C. Presl collected in Sicily. Air-dried, powdered roots of B. aetnensis C. Presl were extracted, identified, and quantified by HPLC. We assessed in cellular free system its effect on superoxide anion, radicals scavenging activity of antioxidants against free radicals like the 1,1-diphenyl-2-picrylhydrazyl radical, and the inhibition of xanthine oxidase activity. In primary rat astroglial cell cultures, exposed to glutamate, we evaluated the effect of the extract on glutathione levels and on intracellular production of reactive oxygen species generated by glutamate. The alkaloid extract of B. aetnensis C. Presl inhibited superoxide anion, restored to control values, the decrease of GSH levels, and the production of reactive oxygen species. Potent antioxidant activities of the alkaloid extract of roots of B. aetnensis C. Presl may be one of the mechanisms by which the extract is effective against health disorders associated to oxidative stress.

    The chemiluminescence of luminol, a measure of oxidative stress, increased immediately as a consequence of reactive oxygen species (ROS) stimulated by this antibiotic. The effect of Ch was dose dependent with maximum stimulus at 8 mg/ml (Vmax); above this concentration the cells began to reduce the production of ROS. The oxidative injury of Ch was counteracted by water extracts of Berberis buxifolia lam, Zizyphus mistol Griseb and Prosopis alba, indigenous fruits from Argentina. The relatively light units (RLU) emitted decreased immediately as a consequence of a protective effect exerted by the extracts of these fruit extracts on blood cells. The three indigenous fruit extracts reduced to a different extent the oxidative injury caused by Ch. B.buxifolia lam exhibited the highest antioxidant capacity followed by Z.mistol Griseb. Water extracts of both fruit extracts were the most effective against the oxidative stress, while P.alba presented better antioxidant capacity in the ethanolic fraction obtained. Hexane extracts showed low protective action on blood cells, with little reduction of area under curve (AUC) of RLU plotted versus time. Leukocytes remained viable in blood samples incubated for 3h with Ch and water extracts of B. buxifolia lam or Z. mistol Griseb (97.1% and 92.5% viability by Trypan blue exclusion, respectively); whereas with Ch only the cells were stressed and viability decreased to 30%. The three fruit extracts protected the viability of leukocytes in parallel with the decrease of ROS. Erythrocytes were not lysed in the presence of Ch.

    Here we conduct research to understand the evolutionary history of a shrubby species known as Agarito (Berberis trifoliolata), an endemic species to the Chihuahuan Desert. We identify genetic signatures based on plastid DNA and AFLP markers and perform niche modelling and spatial connectivity analyses as well as niche modelling based on records in packrats to elucidate whether orogenic events such as mountain range uplift in the Miocene or the contraction/expansion dynamics of vegetation in response to climate oscillations in the Pliocene/Pleistocene had an effect on evolutionary processes in Agarito. Our results of current niche modelling and palaeomodelling showed that the area currently occupied by Berberis trifoliolata is substantially larger than it was during the Last Interglacial period and the Last Glacial Maximum. Agarito was probably confined to small areas in the Northeastern and gradually expanded its distribution just after the Last Glacial Maximum when the weather in the Chihuahuan Desert and adjacent regions became progressively warmer and drier. The most contracted range was predicted for the Interglacial period. Populations remained in stable areas during the Last Glacial Maximum and expanded at the beginning of the Holocene. Most genetic variation occured in populations from the Sierra Madre Oriental. Two groups of haplotypes were identified: the Mexican Plateau populations and certain Northeastern populations. Haplogroups were spatially connected during the Last Glacial Maximum and separated during interglacial periods. The most important prediction of packrat middens palaeomodelling lies in the Mexican Plateau, a finding congruent with current and past niche modelling predictions for agarito and genetic results. Our results corroborate that these climate changes in the Pliocene/Pleistocene affected the evolutionary history of agarito. The journey of agarito in the Chihuahuan Desert has been dynamic, expanding and contracting its distribution

    The kidneys are important organs which have many functions in the body, including the production of hormones, absorbtion of minerals and the filtration of blood, producing urine. Their failure can be fatal, therefore, to focus the study of such herbs which may be useful in treating renal disease is the need of hour. In Pakistan, Cucumis melo and Berberis vulgaris has been commonly used for renal problems. In both of these plants were found flavonoids, alkaloids and terpenes, which may stand for their renal protective properties. Their reported vitamin E contents and antioxidant potentials also provide a base for their defensive mechanism, may be due to their free radical scavenging properties. Further, their diuretic and urinary tract anti-ulcer properties also support their traditional use in renal diseases. Their anti-histaminic and anti-cholinergic properties also provide symptomatic treatment by decreasing prostaglandin level and due to antispasmodic properties. Concluding, both of these plants can be used for renal problems, especially Cucumis melo, which have both the nutritive and medicinal properties. Therefore, the renal disease patients are advised to take much of this particular fruit, especially their seeds to make their kidneys healthy.

    DIG, a liquid herbal preparation made from a mixture of diluted mother tinctures of Berberis vulgaris, Taraxacum officinale and Arctium lappa, was assessed for its antimutagenic properties against mitomycin C. The micronucleus assay on Chinese hamster ovary (CHO)-K1 cells was used to evaluate the in vitro anticlastogenic activity of DIG compared to those of separately diluted mother tinctures. The micronucleus assay was performed on mouse erythrocytes and the comet assay was performed on mouse liver, kidney, lung, brain and testicles to assess the protective effects of DIG (0.2 and 2 % at libitum) against an intraperitoneal injection of mitomycin C (1 mg Kg(-1)) in mice. DIG exerted a powerful anticlastogenic activity, under both pretreatment and simultaneous treatment conditions as assessed by the micronucleus assay in CHO-K1 cells. Its protective activity was greater than that observed for each mother tincture. DIG reduced micronuclei levels in mouse erythrocytes and suppressed >80 % of DNA strand breaks in the liver, kidney, lung, brain and testicles of mice exposed to mitomycin C.

Metformin was used as positive control drug. Food intake, body weight, plasma glucose, oral glucose tolerance test, insulin tolerance test, insulin, and blood-lipid content were measured. The effects of BJSME on the glucose transporter 4 (GLUT4 translocation in L6 myotubes and the GLUT4 protein expression in skeletal muscle as well as phosphorylation of the AMP-activated protein kinase (AMPK in liver and muscle were examined. In vitro and in vivo results indicate that BJSME increased GLUT4 translocation by 1.8-fold and BJSME significantly improved the oral glucose tolerance and low density lipoprotein cholesterol (LDL-C of serum and reduced body weight, glucose, and other related blood-lipid contents. The BJSME treatment also stimulated the phosphorylation of AMPK. Thus, BJSME seems to possess promising beneficial effects for the treatment of T2DM with the possible mechanism via stimulating AMPK activity.

    This research was conducted to investigate two main aims; the first aim was to find if there is a relationship between insulin resistance (IR) and retinol binding protein 4 (RBP4). The second aim was to use berberis vulgaris extract and vitamin A as protective and/or curative agents against insulin resistance. IR was developed by feeding the female rats a high fat diet (HFD) for six weeks then treating or protecting them with b. vulgaris extract (0.2 g/Kg body weight) or vitamin A (12.8μg/Kg/day) for two weeks. HFD intake elevated insulin level and RBP4 expression that associated with hyperglycemia and hyperlipidemia. Co-administration of vitamin A and B. vulgaris extracts reduced blood glucose level, insulin, body weight and RBP4 expression before, during and after HFD. Furthermore, vitamin A reduced the blood glucose, triglycerides (TG) and cholesterol levels. IR syndrome associated with the RBP 4 alteration that gives high indication about the role of RBP4 expression in the IR progression and development. Furthermore, the treatment with vitamin A and/or b. vulgaris alleviated the IR syndrome through the action on RBP4 and Insulin secretion. On the other hand, vitamin A must be avoided for the predisposed IR and prediabetic patients.

    Berberine, palmatine and dehydrocoreximine are end products of protoberberine biosynthesis. These quaternary protoberberines are elicitor inducible and, like other phytoalexins, are highly oxidized. The oxidative potential of these compounds is derived from a diverse array of biosynthetic steps involving hydroxylation, intra-molecular C-C coupling, methylenedioxy bridge formation and a dehydrogenation reaction as the final step in the biosynthesis. For the berberine biosynthetic pathway, the identification of the dehydrogenase gene is the last remaining uncharacterized step in the elucidation of the biosynthesis at the gene level. An enzyme able to catalyze these reactions, (S)-tetrahydroprotoberberine oxidase (STOX, EC 1.3.3.8), was originally purified in the 1980s from suspension cells of Berberis wilsoniae and identified as a flavoprotein (Amann et al. 1984). We report enzymatic activity from recombinant STOX expressed in Spodoptera frugiperda Sf9 insect cells. The coding sequence was derived successively from peptide sequences of purified STOX protein. Furthermore, a recombinant oxidase with protoberberine dehydrogenase activity was obtained from a cDNA library of Argemone mexicana, a traditional medicinal plant that contains protoberberine alkaloids. The relationship of the two enzymes is discussed regarding their enzymatic activity, phylogeny and the alkaloid occurrence in the plants. Potential substrate binding and STOX-specific amino acid residues were identified based on sequence analysis and homology modeling.

    Adulteration or substitution of commercial Berberis aristata and its herbal products with inferior-quality substituents is very common. Metabolic profiling of B. aristata, along with its common adulterants/contaminants/substituents such as B. asiatica, Mahonia borealis and Coscinium fenestratum, was rapidly carried out using direct analysis in real-time mass spectrometry (DART MS) to generate the chemical fingerprints for the differentiation of these species. Phytochemical analysis showed the presence of mainly alkaloids. The identified alkaloids were berberrubine, berberine, jatrorrhizine, ketoberberine, palmatine, dihydropalmatine or 7,8-dihydro-8-hydroxyberberine, berbamine and pakistanamine. Berberine, which was mainly reported from the root and stem bark of B. aristata, was also identified in the leaf along with chlorogenic acid. The DART MS data have been subjected to principal component analysis (PCA). The resulting score plots showed clustering and clear differentiation of the species and plant parts. It is thus apparent that the technique of DART MS followed by PCA is a quick and reliable method for the direct profiling of B. aristata and its adulterant plants and plant parts. The study reports the rapid analytical method to identify the possibility of illegal adulteration/contamination/substitution in potential plant materials and herbal extracts.

    Aedes albopictus is an important arbovirus vector, including dengue. Currently, there is no specific treatment for dengue. Its prevention solely depends on effective vector control measures. In this study, silver nanoparticles (AgNPs) were biosynthesized using a cheap leaf extract of Berberis tinctoria as reducing and stabilizing agent and tested against Ae. albopictus and two mosquito natural enemies. AgNPs were characterized by using UV–vis spectrophotometry, X-ray diffraction, and scanning electron microscopy. In laboratory conditions, the toxicity of AgNPs was evaluated on larvae and pupae of Ae. albopictus. Suitability Index/Predator Safety Factor was assessed on Toxorhynchites splendens and Mesocyclops thermocyclopoides. The leaf extract of B. tinctoria was toxic against larval instars (I–IV) and pupae of Ae. albopictus; LC50 was 182.72 ppm (I instar), 230.99 ppm (II), 269.65 ppm (III), 321.75 ppm (IV), and 359.71 ppm (pupa). B. tinctoria-synthesized AgNPs were highly effective, with LC50 of 4.97 ppm (I instar), 5.97 ppm (II), 7.60 ppm (III), 9.65 ppm (IV), and 14.87 ppm (pupa). Both the leaf extract and AgNPs showed reduced toxicity against the mosquito natural enemies M. thermocyclopoides and T. splendens. Overall, this study firstly shed light on effectiveness of B. tinctoria-synthesized AgNPs as an eco-friendly nanopesticide, highlighting the concrete possibility to employ this newer and safer tool in arbovirus vector control programs.

    Anthocyanins are of interest to the food industry because of their antioxidant power, attractive color, and stability in high acid foods. Powder from the Peruvian berry Berberis boliviana Lechler, rich in nonacylated anthocyanins (7% to 8% dry weight), was incorporated into yogurt samples containing 3 different fat levels. Color (CIE L, a, b, chroma, and hue angle), pigment (monomeric anthocyanin and polymeric color), and total phenolics were monitored over 8 wk of storage and compared to yogurt treatments containing purple carrot acylated anthocyanins, red beet betalaines, or FD&C Red nr 40. Anthocyanin profiles were analyzed by HPLC coupled to photodiode array and mass detectors. Color of yogurt containing B. boliviana anthocyanins at 20 mg cyanidin-3-glucoside (cy-3-glu) equivalents/100 g yogurt (L*= 65, chroma = 14, and hue angle = 335 degrees ) was similar to commercial blueberry yogurt (L*= 65, chroma = 10.5, and hue angle = 341 degrees ). High color, pigment, and phenolic stability were observed in yogurts colored with B. boliviana, independent of the fat matrix. Acylated anthocyanins from purple carrot extracts exhibited increased stability with higher fat content. Anthocyanin degradation followed 1st-order kinetics. Pigment half-lives were 125 and 104 d for nonacylated anthocyanins at 10 and 20 mg cy-3-glu equivalents/100 g yogurt and 550.2, 232.6, and 128.9 d for acylated anthocyanins at 20 mg of cy-3-glu equivalents/100 g of 4%, 2%, and 0% fat yogurt. Addition of B. boliviana whole berry powder to yogurt matrices produced an attractive, stable anthocyanin-rich product, eliminating the need for industrial colorant extraction.

    Berberis lycium Royle (Berberidacea) from Pakistan and its alkaloids berberine and palmatine have been reported to possess beneficial pharmacological properties. In the present study, the anti-neoplastic activities of different B. lycium root extracts and the major constituting alkaloids, berberine and palmatine were investigated in p53-deficient HL-60 cells. The strongest growth inhibitory and pro-apoptotic effects were found in the n-butanol (BuOH) extract followed by the ethyl acetate (EtOAc)-, and the water (H{sub 2}O) extract. The chemical composition of the BuOH extract was analyzed by TLC and quantified by HPLC. 11.1 {mu}g BuOH extract (that was gained from 1 mg dried root) contained 2.0 {mu}g berberine and 0.3 {mu}g/ml palmatine. 1.2 {mu}g/ml berberine inhibited cell proliferation significantly, while 0.5 {mu}g/ml palmatine had no effect. Berberine and the BuOH extract caused accumulation of HL-60 cells in S-phase. This was preceded by a strong activation of Chk2, phosphorylation and degradation of Cdc25A, and the subsequent inactivation of Cdc2 (CDK1). Furthermore, berberine and the extract inhibited the expression of the proto-oncogene cyclin D1. Berberine and the BuOH extract induced the acetylation of {alpha}-tubulin and this correlated with the induction of apoptosis. The data demonstrate that berberine is a potent anti-neoplastic compound that acts via anti-proliferative and pro-apoptotic mechanisms independent of genotoxicity.

    Background Berberis aristata, because of its berberine content, and Monascus purpureus fermented rice, because of the presence of monacolins (naturally derived statins), are widely investigated food-grade ingredients used to formulate cholesterol-lowering supplements. Although they are extensively used, berberine is poorly absorbed and monacolins are poorly chemically characterized, not standardized, and possibly contaminated with toxic compounds. Silymarin is reported to enhance berberine absorption, while Monakopure™-K20 (MK-20) is a highly standardized red yeast rice containing monacolins K and KA in the ratio of 1:1 but not secondary monacolins, dehydromonacolins, or citrinin. Aim The effects of a cholesterol-lowering supplement (Berberol®K) containing berberine, silymarin, and MK-20 (BSM) in patients with dyslipidemia were clinically analyzed. Methods The clinical role of BSM in naïve and in statin-intolerant patients was retrospectively evaluated and the effects observed were compared with those obtained in patients without treatment or treated with lovastatin. Results Total cholesterol, low density lipoprotein, and triglyceride levels were approximately 4%, 6%, and 11% lower, respectively, and the creatine phosphokinase increase was reduced in patients treated with BSM compared to those treated with lovastatin. Similar results were also obtained in statin-intolerant subjects where BSM was administered as add-on therapy to ezetimibe or fenofibrate. Conclusion BSM is a food supplement potentially useful 1) as a primary intervention in low-cardiovascular-risk subjects with dyslipidemia; 2) as add-on therapy in mildly statin-intolerant patients; and 3) in dyslipidemic patients with a negative perception of statins who prefer a treatment seen as natural.

    In present study, the anthocyanin composition and content of the fruit of B. heteropoda Schrenk were determined for the first time. The total anthocyanins were extracted from the fruit of B. heteropoda Schrenk using 0.5% HCl in 80% methanol and were then purified using an AB-8 macroporous resin column. The purified anthocyanin extract (PAE) was evaluated by high-performance liquid chromatography with a diode array detector (HPLC-DAD) and HPLC-high resolution-electrospray ionization-mass spectrometry (HPLC-HR-ESI-MS) under the same experimental conditions. The results revealed the presence of seven different anthocyanins. The major anthocyanins purified by preparative HPLC were confirmed to be delphinidin-3-O-glucopyranoside (30.3%), cyanidin-3-O-glucopyranoside (33.5%), petunidin-3-Ο-glucopyranoside (10.5%), peonidin-3-O-glucopyranoside (8.5%) and malvidin-3-O-glucopyranoside (13.8%) using HPLC-HR-ESI-MS and NMR spectroscopy. The total anthocyanin content was 2036.6 ± 2.2 mg/100 g of the fresh weight of B. heteropoda Schrenk fruit. In terms of its total reducing capacity assay, DPPH radical-scavenging activity assay, ferric-reducing antioxidant power (FRAP) assay and ABTS radical cation-scavenging activity assay, the PAE also showed potent antioxidant activity. The results are valuable for illuminating anthocyanins composition of B. heteropoda Schrenk and for further utilising them as a promising anthocyanin pigment source. This research enriched the chemical information of B. heteropoda Schrenk.

    Full Text Available In an investigation on kinetics of seedless barberry drying at 35, 45 and 55°C in vacuum and with water vapor and citric acid pre-treatments, the value of effective moisture Diffusivity (Deff was calculated using the second Fick's diffusion equation, activation energy was determined and drying process was simulated by 10 common mathematical equations of thin layer-drying models. Results which were obtained from regression analysis of studied models showed that approximation of diffusion model had the best fitting for vacuum-drying of barberries through available data. Drying barberry took place in the falling rate drying period and pre-treated samples had higher drying rate. The effective diffusivity coefficient for vacuum-drying of barberry fruits was evaluated between 0.022810-10 and 0.253810-10m2/s, which increased along with temperature rise. An Arrhenius equation for drying of seedless barberry with activation energy values ranged from 27.618 to 92.493 kJ/mol expressed the effect of temperature on moisture diffusivity.

The trend is towards a positive transgression of previous boundaries, and scholars have shifted attention from the disciplinary approach to the transdisciplinaryand inter-disciplinary research. However, elements and trends of the past still influence the relationship between Berber literary studies and African literary studies in Italy. This paper offers a first reflection on the long-term relationships between Africanist studies and studies on Berber literature by taking into account conjunctures and disjunctures in the complex construction of thegeographical and cultural notions of (and divide between ‘Africa’ and ‘North Africa’.The aim is to understand specificity and continuity of the relationship betweenBerber studies and Africanist studies in Italy when compared to international studies.Looking at the Italian studies of Berber literature, one finds a strong influence of the linguistic and philological approaches. Moreover, one recognizes the tendency of thestudies to look ‘East’ rather than ‘South’ in establishing their cultural and political framework of reference. On the other hand, studies that give attention to new developments in Berber written literature spring usually from African 'post-colonial' literary studies. However, the situation is also evolving in the specific field of Italian Berber studies.

    Full Text Available In this study, the drying kinetics of seedless barberry fruit was studied at 55, 65 and 75˚C air temperatures and 1±0.2 m/s air velocity in a laboratory thin layer dryer with forced convection. Samples were subjected to two different pretreatments (citric acid and vapor. The drying of seedless barberry fruit took place in the falling rate drying period. Ten thin layer-drying models were fitted to the experimental moisture ratio. Compared with other models the Midilli et al. (2002 drying model was found to satisfactorily describe the drying curves of barberry with highest amounts of coefficient of determination (r2 and lowest amounts of reduced chi-square(x2, Mean Bias Error (MBE and Root Mean Square Error (RMSE. The effective moisture diffusivity (Deff of barberry increased as the drying air temperature increased. An Arrhenius relation with activation energy values of 45.577 kJ/mol (citric acid pretreatment expressed the effect of temperature on the diffusivity.

    Background Statin intolerance is a medical condition often leading patients to nonadherence to the prescribed therapy or to a relevant reduction of the statin dosage. Both situations determine a totally or partially uncontrolled lipid profile, and these conditions unquestionably increase the risk of cardiovascular events. Methods We enrolled hypercholesterolemic, type 2 diabetic patients complaining of intolerance to statins. Some of them had reduced the statin dose ‘until the disappearance of symptoms’; others had opted for treatment with ezetimibe; and yet others were not undergoing any treatment at all. All patients of the three groups were then given a fixed combination of berberine and silymarin (Berberol®), known from previous papers to be able to control both lipidic and glycemic profiles. Results The tested product both as a single therapy and as add-on therapy to low-dose statin or to ezetimibe reduced triglycerides, low-density lipoprotein cholesterol, fasting blood glucose, and glycosylated hemoglobin in a significant manner without inducing toxicity conditions that might be somehow ascribed to a statin-intolerant condition. Conclusion Our study demonstrates that use of Berberol®, administered as a single or add-on therapy in statin-intolerant subjects affected by diabetes and hypercholesterolemia is a safe and effective tool capable of improving the patients’ lipidic and glycemic profiles.

    The present paper represents the ethnopharmacological survey of Sudhan Gali, Kashmir, Pakistan. The study revealed that 12 plant species belonging to 11 famihes were used for the treatment of stomach, diabetes and ophthalmic diseases by the local people in Sudhan GaB. Achillea millefolium, Aconitun heterophyllum, Berberis lycium, Polygonum amplexicaule, Mentha longifolia, Paeonia emodi, Plantago lanceolata were locally used for stomach related problemstreatment; Berberis lycium, Skimmia lareola, Solanum dulcamara for diabetes and Geranium wallichianum, Artemisia vulgaris, Solanum dulcamara, and Corydalis crassifolia used for the treatment of ophthalmic diseases. Two species Berberis lycium and Solanum dulcamara have multipurpose value. Former is used to treat stomach as well as diabetes while latter is used to treat not only to diabetes but also ophthalmic diseases. According to IUCN categories, out of these 12 plant species collected and marketed, Polygonum amplexicaule and Paeonia emodi are endangered, Aconitum heterophyllum; Berberis lycium species are vulnerable while Plantago lanceolata and Skimmia lareola species are rare.The availability of these medicinal plants has decreased during the past 20 years and these are facing a drastic biotic pressure due to their extensive usage and non-scientific methods of collection. It is quite evident that these valuable native medicinal plants species are going to decline in number and ultimately will become extinct if no timely proper conservation strategies are adopted.

  20. Quality Evaluation of Ayurvedic Crude Drug Daruharidra, Its Allied Species, and Commercial Samples from Herbal Drug Markets of India

    Directory of Open Access Journals (Sweden)

    Sharad Srivastava

    2013-01-01

    Full Text Available Berberis aristata known as “Daruharidra” in Ayurveda is a versatile medicinal plant used singly or in combination with other medicinal plants for treating a variety of ailments like jaundice, enlargement of spleen, leprosy, rheumatism, fever, morning/evening sickness, snakebite, and so forth. A major bioactive marker of this genus is an alkaloid berberine, which is known for its activity against cholera, acute diarrhea, amoebiasis, and latent malaria and for the treatment of oriental sore caused by Leishmania tropica. Although the roots of B. aristata are considered as the official drug (Ayurvedic Pharmacopoeia of India, the study revealed that different species of Berberis, namely. B. asiatica, B. chitria, and B. lycium are also used under the name of Daruharidra in different parts of the country. Detailed physicochemical and phytochemical studies of subjects like total ash, acid insoluble ash, tannins, and total alkaloids were calculated from the shade dried powdered material according to the recommended procedures. Further, heavy metal studies and quantitative estimation of berberine through HPTLC have also been performed as per ICH guidelines. A detailed study of four Berberis species, namely B. aristata, B. asiatica, B. chitria, and B. lycium, which are implicated as Daruharidra and collected from wild and ten commercial samples procured from various important drug markets in India has been carried out, which may be useful to pharmaceutical industries for the authentication of the commercial samples and exploring the possibilities of using other species as a substitute of B. aristata.

    The incidence of fungal infections and, in particular, the incidence of fungal antibiotic resistance, which is associated with biofilm formation, have significantly increased, contributing to morbidity and mortality. Thus, new therapeutic strategies need to be developed. In this context, natural products have emerged as a major source of possible antifungal agents. Berberine is a protoberberine-type isoquinoline alkaloid isolated from the roots, rhizomes, and stem bark of natural herbs, such as Berberis aquifolium, Berberis vulgaris, Berberis aristata, and Hydrastis canadensis, and of Phellodendron amurense Berberine has been proven to have broad antibacterial and antifungal activity. In the present study, the potential antifungal effect of berberine against fluconazole-resistant Candida and Cryptococcus neoformans strains, as well as against the biofilm form of Candida spp., was assessed. The antifungal effect of berberine was determined by a broth microdilution method (the M27-A3 method of the Clinical and Laboratory Standards Institute) and flow cytometry techniques, in which the probable mechanism of action of the compound was also assessed. For biofilm assessment, a colorimetric 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay was used to determine the susceptibility of sessile cells. The isolates used in the study belonged to the Laboratory of Bioprospection and Experiments in Yeast (LABEL) of the Federal University of Ceará. After 24 and 72 h, fluconazole-resistant Candida and Cryptococcus neoformans strains showed berberine MICs equal to 8 μg/ml and 16 μg/ml, respectively. Cytometric analysis showed that treatment with berberine caused alterations to the integrity of the plasma and mitochondrial membranes and DNA damage, which led to cell death, probably by apoptosis. Assessment of biofilm-forming isolates after treatment showed statistically significant reductions in biofilm cell activity (P < 0.001).

    Full Text Available In this study, Berberine colorant extracted from berberis vulgaris root was applied on wool fiber using alum (aluminum potassium sulfate, copper sulfate and potassium dichromate as mordant. The effect of treatment variables such as amount of mordant, time and temperature on the color strength of dyed fibers was examined. The fastness properties of dyed wool against washing, light and wet rubbing were evaluated. the use of metal mordants increased the color strength of the dyed goods. Increase in dyeing time and temperature caused deeper shades. All mordants, increased the rub fastness and wash fastness of dyed samples, but the light fastness was increased except in case of alum. Berberine is a cationic dye and because of it's quaternary ammonium structure can act as an antibacterial agent. So, dyed samples were tested for antibacterial activity using AATCC test method 100-2004. The dyed wool represented a high level of antibacterial activity. The extract of the berberis vulgaris can be considered as a natural dye of acceptable fastness properties together with excellent antibacterial activity for woolen textiles.DOI: http://dx.doi.org/10.5755/j01.ms.18.3.2437

    Evidence obtained on the relation between the pH of the medium and the growth of intact stem sections is compatible with the acid-growth theory only if the proton conductance of the cuticle is an effective barrier to the entry or exit of protons from the tissue. By measuring the rate at which protons cross frozen-thawed epidermal strips of sunflower (Helianthus annus L.) and soybean hypocotyls (Glycine max Morr.) and enzymically isolated cuticles of Berberis aquifolium Persh. and tomato (Lycopersicum esculentum Mill.) fruit, we have now demonstrated the low proton conductance of the cuticular layer. Unless the conductance is enhanced by abrasion of the cuticle or by removal of the cuticular waxes, proton movement into and out of a tissue across the cuticle will be significant only over long time periods.

    Full Text Available Inhibition of acetylcholinesterase (AChE is a common treatment for early stages of the most general form of dementia, Alzheimer’s Disease (AD. In this study, methanol, dichloromethane and aqueous crude extracts from 80 Traditional Chinese Medical (TCM plants were tested for their in vitro anti-acetylcholinesterase activity based on Ellman’s colorimetric assay. All three extracts of Berberis bealei (formerly Mahonia bealei, Coptis chinensis and Phellodendron chinense, which contain numerous isoquinoline alkaloids, substantially inhibited AChE. The methanol and aqueous extracts of Coptis chinensis showed IC50 values of 0.031 µg/mL and 2.5 µg/mL, therefore having an up to 100-fold stronger AChE inhibitory activity than the already known AChE inhibitor galantamine (IC50 = 4.33 µg/mL. Combinations of individual alkaloids berberine, coptisine and palmatine resulted in a synergistic enhancement of ACh inhibition. Therefore, the mode of AChE inhibition of crude extracts of Coptis chinensis, Berberis bealei and Phellodendron chinense is probably due to of this synergism of isoquinoline alkaloids. All extracts were also tested for their cytotoxicity in COS7 cells and none of the most active extracts was cytotoxic at the concentrations which inhibit AChE. Based on these results it can be stated that some TCM plants inhibit AChE via synergistic interaction of their secondary metabolites. The possibility to isolate pure lead compounds from the crude extracts or to administer these as nutraceuticals or as cheap alternative to drugs in third world countries make TCM plants a versatile source of natural inhibitors of AChE.

    Full Text Available Anthropogenic disturbances often change ecological communities and provide opportunities for non-native species invasion. Understanding the impacts of disturbances on species invasion is therefore crucial for invasive species management. We used generalized linear mixed effects models to explore the influence of land-use history and distance to roads on the occurrence and abundance of two invasive plant species (Rosa multiflora and Berberis thunbergii in a 900-ha deciduous forest in the eastern U.S.A., the Powdermill Nature Reserve. Although much of the reserve has been continuously forested since at least 1939, aerial photos revealed a variety of land-uses since then including agriculture, mining, logging, and development. By 2008, both R. multiflora and B. thunbergii were widespread throughout the reserve (occurring in 24% and 13% of 4417 10-m diameter regularly-placed vegetation plots, respectively with occurrence and abundance of each varying significantly with land-use history. Rosa multiflora was more likely to occur in historically farmed, mined, logged or developed plots than in plots that remained forested, (log odds of 1.8 to 3.0; Berberis thunbergii was more likely to occur in plots with agricultural, mining, or logging history than in plots without disturbance (log odds of 1.4 to 2.1. Mining, logging, and agriculture increased the probability that R. multiflora had >10% cover while only past agriculture was related to cover of B. thunbergii. Proximity to roads was positively correlated with the occurrence of R. multiflora (a 0.26 increase in the log odds for every 1-m closer but not B. thunbergii, and roads had no impact on the abundance of either species. Our results indicated that a wide variety of disturbances may aid the introduction of invasive species into new habitats, while high-impact disturbances such as agriculture and mining increase the likelihood of high abundance post-introduction.

    Full Text Available Pharynx is a cross road between respiratory tract and alimentary canal and is a frequent site of inflammatory pathologies. Chronic pharyngitis is not a life threatening disorder but surely an incapacitating malady by virtue of its recalcitrant behaviour, frequent antibiotic consumption and compromised social output and quality of life and hence can not be nominated as innocuous disease by any stretch of imagination per se. Berberis aristata DC. (Family - Berberidaceae or Daru Haridra in Ayurveda is historically and time tested drug used primarily in inflammatory disorders. The usage of Berberis aristata is well documented in non healing wounds, infective disorders of the eye, hepatobiliary stimulation, chronic inflammatory mucosal disorders and skin diseases. Berberine which is chief phytochemical active constituent of Barberis aristata as has got proven action as an anti inflammatory, anti hyperplastic, immunomodulation, enhancement of delayed T cell mediated activity, anti oxidant, anti pyretic, analgesic and cytoprotective actions. Present randomized, single blind, prospective, unicenteral experimental clinical trial intends to compare to effectiveness of Barberis aristata extract as systemic administration and local application (oral rinse by ramifying clinically diagnosed 120 chronic pharyngitis patients into two trial groups. Paired ‘t’ test was used to evaluate the individual effectiveness of the trial drugs and also to compare the outcome of the two trial drugs administration as an inter group comparison. Statistical analysis conspicuously reflected the superior outcome in favour of systemic usage of Barberis aristata extract than that of oral rinse and the difference may be attributed to the fact that constant salivation had restricted the contact time of the drug on inflamed mucosa to a few minutes only and flushing is the end result of the locally applied drug invariably, but this incapacitation is bypassed by making the drug

    Full Text Available Peroxidase, polyphenol oxidase (PPO, phenolic compounds and total sugars (TS were investigated during root formation in cuttings of Berberis vulgaris var. asperma (BVA and Berberis thunbergii var. atropurpurea (BTA treated with indole-3-butyric acid (IBA and IBA+H2O2. Rooting was observed on BTA cuttings but not on BVA cuttings. The BTA cuttings treated with IBA and IBA+H2O2 showed higher rooting percentages, number of roots, and root length over the control. Those treated with IBA+H2O2 recorded the lowest peroxidase activity after planting. BTA cuttings treated with IBA+H2O2 showed the highest peroxidase activity at 50 d after planting; BVA cuttings under different treatments showed no significant difference for peroxidase activity at planting time or up to 80 d after planting. PPO activity for the BTA cuttings in the control treatment was lower than for other treatments during root formation. The cuttings in the IBA and IBA+H2O2 treatments showed increased PPO activity from 0 to 50 d after planting and a slight decrease in PPO activity from 60 to 80 d after planting. PPO activity for the BVA cuttings was significantly lower than for BTA during root formation. The BTA cuttings treated with IBA and IBA+H2O2 showed the highest phenolic compound content during root formation. The BVA cuttings displayed higher TS than BTA during the initial stage of root formation. A comparison of the anatomical structure of easy-to-root and difficult-to-root cuttings indicated that physical inhibitors did not affect the rooting capacity of BVA.

    Full Text Available There are a number of medicinal combinations in the Iranian traditional medicine which are commonly used as tonic for liver. In this review, we have introduced some medicinal plants that are used mainly for the treatment of liver disorders in Iranian folk medicine, with focus on their hepatoprotective effects particularly against CC14 agent. In this study, online databases including Web of Science, PubMed, Scopus, and Science Direct were searched for papers published from January 1970 to December 2013. Search terms consisted of medicinal plants, traditional medicine, folk medicine, hepatoprotective, Iran, liver, therapeutic uses, compounds, antioxidant, CC14, anti-inflammatory, and antihepatotoxic, hepatitis, alone or in combination. Allium hirtifolium Boiss., Apium graveolens L., Cynara scolymus, Berberis vulgaris L., Calendula officinalis, Nigella sativa L., Taraxacum officinale, Tragopogon porrifolius, Prangos ferulacea L., Allium sativum, Marrubium vulgare, Ammi majus L., Citrullus lanatus Thunb, Agrimonia eupatoria L. and Prunus armeniaca L. are some of the medicinal plants that have been used for the treatment of liver disorders in Iranian folk medicine. Out of several leads obtained from plants containing potential hepatoprotective agents, silymarin, β-sitosterol, betalain, neoandrographolide, phyllanthin, andrographolide, curcumin, picroside, hypophyllanthin, kutkoside, and glycyrrhizin have been demonstrated to have potent hepatoprotective properties. Despite encouraging data on possibility of new discoveries in the near future, the evidence on treating viral hepatitis or other chronic liver diseases by herbal medications is not adequate.

    Full Text Available Cardiovascular diseases are one of the leading causes of morbidity and mortality in women after menopause and 56% of all causes of death in Western European countries. Nowadays, with increasing life span, women spend approximately one-third of their life-time in postmenopausal state; therefore, the development of new strategies to improve the prevention and treatment of menopause-associated pathologies is important topic in clinical practice. The studies to assess the safety of hormone replacement therapy in women with estrogen deficiency have not been conclusive due to the relative contraindications; therefore, hormone replacement therapy is prescribed only in selected cases and for a limited time. For this reason, today women are encouraged to use naturally available compounds to prevent or to attenuate menopausal symptoms and correlated pathologies, with fewer side effects. Among these compounds, berberine, an isoquinoline alkaloid derived from plants of the generis Berberis, has been recognized as being capable of decreasing oxidative stress, LDL, triglycerides, and insulin resistance and of improving the mood. This review describes the cellular and clinical effects associated with the use of berberine, which suggest that this molecule could be an effective natural supplement to ensure a smooth peri- and postmenopausal transition.

    The aim of this study is to document the traditional knowledge on the utilization of Biofencing plants of Himachal Pradesh, Northwest Himalaya. The study was imperative because of dearth in the data pertaining to Biofencing plants in the study areas. The whole study area was stratified into three zones and a widespread field survey and random sampling method was adopted to assess the live fencing diversity of the region. The region occupies total 61 species. 10 (trees), 45 (shrubs), 4 (herbs) and 2 were climbers. These belong to the 25 families. Rosaceae, Fabaceae, Berberidaceae, Elaeagnaceae and Euphorbiaceae are dominant families. Among genera, Berberis and Rosa are dominant. Of the total, 55 species are medicinally important and among these 20% are used for stomach disorders; 17% (skin complaints), 14% (asthma), 11% (fever and joint pains), 3% (aphrodisiac and snake bite), 1% (anticancerous and nerve disorders). Ethnobotanical assessment showed that 33 of the recorded species are used as fuel, 20 (edible), 8 (fodder) and 4 (fiber and ornamental). This traditional knowledge of Biofencing plants contributes to the conservation of biodiversity and provides resource of economic and ecological interest and also decreasing the pressure on forests. So there is need to encourage the practice of using plant species for fencing in this region.

    Berberine is an isoquinoline alkaloid which is extracted from bark and roots of Berberis vulgaris plant. It has been used in ayurvedic medicine as it possess antimicrobial, antidiabetic, anticancer, antioxidant properties etc. But poor solubility of berberine leads to poor stability and bioavailability in medical formulations decreasing its efficacy. Hence nanoformulations of berberine can help in removing the limiting factors of alkaloid enhancing its utilization in pharmaceutical industry. Sodium alginate polymer was used to encapsulate berberine within nanoparticles by emulsion solvent evaporation method using tween 80 as a surfactant. Two factors and three level in central composite design was used to study the formulation. The optimized formulation (1% v/v of Tween 80 and 0.01% w/v of sodium alginate) of polymeric nanoparticles was taken for further evaluations. The size of synthesized nanoparticles was found to be 71.18 nm by particle size analysis (PSA). The berberine loaded polymeric nanoparticles showed better antibacterial activity compared to aqueous solution of berberine by well diffusion assay.

    Responses of plant functional traits to environmental variability are of enduring interest because they constrain organism performance and ecosystem function. However, most inferences regarding plant functional trait response to climatic variability have been limited to the modern period. To better understand plant functional response to long-term climate variability and how adjustments in leaf morphology may contribute to patterns of species establishment, persistence, or extirpation, we measured specific leaf area (SLA) from macrofossils preserved in ancient packrat middens collected along the Arizona/New Mexico border, USA. Our record spanned more than 32,000 years and included six woodland and Chihuahuan Desert species: Berberis cf. haematocarpa, Juniperus cf. coahuilensis, Juniperus osteosperma, Larrea tridentata, Prosopis glandulosa and Parthenium incanum. We predicted that regional climatic warming and drying since the late Pleistocene would result in intraspecific decreases in SLA. As predicted, SLA was positively correlated with midden age for three of the six species (L. tridentata, J. osteosperma, B. cf. haematocarpa). SLA was also negatively correlated with December (L. tridentata, J. cf. coahuilensis) or June (B. cf. haematocarpa, J. osteosperma) insolation. A unique record of vegetation community dynamics, plant macrofossils preserved in packrat middens also represent a rich and largely untapped source of information on long-term trends in species functional response to environmental change.

    Background Suboptimal glycemic control is a common situation in diabetes, regardless of the wide range of drugs available to reach glycemic targets. Basic research in diabetes is endeavoring to identify new actives working as insulin savers, use of which could delay the introduction of injectable insulin or reduce the insulin dose needed. Commonly available as a nutraceutical, berberine is a potential candidate. Methods and results Because its low oral bioavailability can be overcome by P-glycoprotein inhibitors like herbal polyphenols, we have tested the nutraceutical combination of Berberis aristata extract and Silybum marianum extract (Berberol®) in type 2 diabetes in terms of its additive effect when combined with a conventional oral regimen for patients with suboptimal glycemic control. After 90 days of treatment, the nutraceutical association had a positive effect on glycemic and lipid parameters, significantly reducing glycosylated hemoglobin, basal insulin, homeostatic model assessment of insulin resistance, total and low-density lipoprotein cholesterol, and triglycerides. A relevant effect was also observed in terms of liver function by measuring aspartate transaminase and alanine transaminase. The product had a good safety profile, with distinctive gastrointestinal side effects likely due to its acarbose-like action. Conclusion Although further studies should be carried out to confirm our data, Berberol could be considered a good candidate as an adjunctive treatment option in diabetes, especially in patients with suboptimal glycemic control.

    The barberry (Berberis vulgaris) extract which is a rich source of anthocyanins was used for spray drying encapsulation with three different wall materials, i.e., combination of maltodextrin and gum Arabic (MD+GA), maltodextrin and gelatin (MD+GE), and maltodextrin (MD). Response Surface Methodology (RSM) was applied for optimization of microencapsulation efficiency and physical properties of encapsulated powders considering wall material type as well as different ratios of core to wall materials as independent variables. Physical characteristics of spray-dried powders were investigated by further analyses of moisture content, hygroscopicity, degree of caking, solubility, bulk and absolute density, porosity, flowability and microstructural evaluation of encapsulated powders. Our results indicated that samples produced with MD+GA as wall materials represented the highest process efficiency and best powder quality; the optimum conditions of microencapsulation process for barberry anthocyanins were found to be the wall material content and anthocyanin load of 24.54% and 13.82%, respectively. Under such conditions, the microencapsulation efficiency (ME) of anthocyanins could be as high as 92.83%.

    Full Text Available Berberis hartwegii Benth., Berberidaceae, Hamelia patens Jacq., Rubiaceae, Dendropanax arboreus (L. Decne & Planch., Araliaceae, Erythrina herbacea L., Fabaceae, and Zanthoxylum caribaeum Lam., Rutaceae, acetone extracts were selected on the basis of their use in traditional Mexican medicine to treat scabies or skin diseases. Anti-dermatophyte activity in vitro was evaluated using the agar dilution assay, and the therapeutic efficacy of B. hartwegii and Z. caribaeum were tested against experimental tinea pedis. The infected animals were treated intragastrically daily for seven days with 2.5 and 5 mg/kg of acetone extracts. The acetone extract of H. patens exhibited 100% growth inhibition against T. mentagrophytes and E. floccosum at 100.0 and 50.0 µg/ml, respectively, and B. hartwegii inhibited growth of M. canis and T. mentagrophytes at 100.0 µg/ml. Effective treatments with 2.5 mg/kg of Z. caribaeum and B. hartwegii extract were comparable with 1 mg/kg of clotrimazole in mice. Liver profile tests and histological analyses did not exhibit any signs of toxicity and the Ames test indicated that both extracts were safe when evaluated in strains TA98, TA100 and TA102. Our results suggest the potential for the future development of new antifungal drugs from B. hartwegii or Z. caribaeum.

    We identified the winter plant species consumed by red panda in the Dhorpatan Hunting Reserve of eastern Nepal and compared this to the early-summer diet which was determined previously by Panthi et al. (2012). In addition, we estimated the proximate nutritional content of the leaves identified in red panda diet for both seasons, and we used nutritional geometry to explore macronutrient balance of leaves from the two different sampling periods. We identified six different plants in winter scats, which were the same as found in the previously determined early-summer diet. Arundinaria spp. bamboos were the main species found (82.1 % relative frequency), followed by Acer spp. (6.3 %), Betula utilis (4.6 %), Quercus semicarpifolia (3.7 %), Berberis spp. (1.3 %), and lichens (1.0 %), leaving 2.0 % unidentified. Geometric analysis suggested that the macronutrient balance of seasonal diets were similar in nutrient balance to the most frequently consumed Arundinaria spp. Differences in macronutrient balance may indicate seasonal nutrient preferences, such as increased carbohydrate intake in winter for thermogenesis, and increased protein and lipid intake in early summer to support reproduction and lactation; however, these differences may also indicate differences in resource availability. Habitat conserved for red panda in the region should include sufficient Arundinaria spp. as well as lesser consumed plants which may serve as complimentary foods.

    The antiamoebic effect of a crude drug formulation against Entamoeba histolytica was studied. In the traditional system of medicine in India, the formulation has been prescribed for intestinal disorders. It comprises of five medicinal herbs, namely, Boerhavia diffusa, Berberis aristata, Tinospora cordifolia, Terminalia chebula and Zingiber officinale. The dried and pulverized plants were extracted in ethanol together and individually. In vitro amoebicidal activity was studied to determine the minimal inhibitory concentration (MIC) values of all the constituent extracts as well as the whole formulation. The formulation had a MIC of 1000 micrograms/ml as compared with 10 micrograms/ml for metronidazole. In experimental caecal amoebiasis in rats the formulation had a curative rate of 89% with the average degree of infection (ADI) reduced to 0.4 in a group dosed with 500 mg/kg per day as compared with ADI of 3.8 for the sham-treated control group of rats. Metronidazole had a cure rate of 89% (ADI = 0.4) at a dose of 100 mg/kg per day and cured the infection completely (ADI = 0) when the dosage was doubled to 200 mg/kg per day. There were varying degrees of inhibition of the following enzyme activities of crude extracts of axenically cultured amoebae: DNase, RNase, aldolase, alkaline phosphatase, acid phosphatase, alpha-amylase and protease.

    The main goal of present study was the development, optimization and application of different extraction protocols, especially those employing green technologies, in order to obtain from Berberis cretica extracts with high antioxidant capacity. For this purpose, the applied methods: maceration, ASE and SFE coupled with ASE were incorporated. The antioxidant assessment was carried out using DPPH and total phenolic content (Folin-Ciocalteu) assays. Major constituents were elucidated using HPLC-DAD and UHPLC-HRMS/MS (hybrid IT-Orbital trap spectrometer) equipped with an ESI probe. The chromatographic and spectral data revealed the presence of several simple phenolic acids, derivatives of both caffeic and benzoic acids, and flavonoids in the produced extracts. It was clearly evidenced that the extraction method and solvents used affected both the activity and the chemical content of the results, significantly. The most beneficial conditions were calculated for methanol and water:ethanol (50:50) extracts derived from the combination of SFE and ASE methodologies. Obtained results classify Cretan barberry as a strong antioxidant agent.

    The excessive production of reactive oxygen species in nervous tissues is considered one of the major risk factors of neurodegenerative diseases. During the last two decades, much attention has been paid to the antioxidant and anti-inflammatory activity of natural products and compounds isolated from natural products which are often characterized by high efficacy and low adverse effects. Berberine is an isoquinoline alkaloid, widely present in different medicinal herbs, especially in the genus Berberis. It is mainly used as antidiarrhoeal, antibacterial, antifungal, and antiprotozoal agent. However, current research has focused on its beneficial role in neurodegenerative diseases, mainly due to its powerful antioxidant effect. The therapeutic potential of Berberine in different neurodegenerative diseases such as Alzheimer, Parkinson and Huntington disease has been brought to evidence by numerous studies. However, a limited number of reviews focus on the beneficial role of Berberine against neurodegeneration. The main objective of this review is to discuss the role of oxidative stress in neurodegeneration and the potential role of antioxidant compounds, in particular Berberine which is analyzed in its chemical structure, source, bioavailability, therapeutic potential, with special attention to its mechanism of action at a molecular level.

    Galangin is an active pharmacological ingredient from propolis and Alpinia officinarum Hance, and has been reported to have anti-cancer and antioxidative properties. Berberine, a major component of Berberis vulgaris extract, exhibits potent anti-cancer activities through distinct molecular mechanisms. However, the anticancer effect of galangin in combination with berberine is still unknown. In the present study, we demonstrated that the combination of galangin with berberine synergistically resulted in cell growth inhibition, apoptosis and cell cycle arrest at G2/M phase with the increased intracellular reactive oxygen species (ROS) levels in oesophageal carcinoma cells. Pretreatment with ROS scavenger promoted the apoptosis dramatically induced by co-treatment with galangin and berberine. Treatment with galangin and berberine alone caused the decreased expressions of Wnt3a and β-catenin. Interestingly, combination of galangin with berberine could further suppress Wnt3a and β-catenin expression and induce apoptosis in cancer cells. Additionally, in nude mice with xenograft tumors, the combinational treatment of galangin and berberine significantly inhibited the tumor growth without obvious toxicity. Overall, galangin in combination with berberine presented outstanding synergistic anticancer role in vitro and in vivo, indicating that the beneficial combination of galangin and berberine might provide a promising treatment for patients with oesophageal carcinoma.

    Berberine is a quaternary ammonium salt from the protoberberine group of isoquinoline alkaloids found in such plants as gender Berberis. Berberine is recognised to improve glucose and lipid metabolism disorders and preliminary clinical evidences suggest the ability of berberine to reduce endothelial inflammation improving vascular health, even in patients already affected by cardiovascular diseases, suggesting a possible interesting role of berberine and its metabolites in clinical practice. However, its physicochemical properties, pharmacokinetic, and metabolism are not fully elucidated and contradictory data have been reported. This review provides a summary regarding the pharmacological and biological features of berberine, with a focus on berberine as well as their pharmacologically active metabolites and the different mechanisms underlying their activities in order to clarify the correct use of berberine supplementation, alone or in association with other nutraceuticals, for the management of metabolic disorders associated to increased cardiovascular disease risk. A particular attention has also been given to the available clinical trials assessing its short- and middle- term use tolerability, safety and efficacy in various conditions, such as dyslipidaemia, impaired fasting glucose, metabolic syndrome and type 2 diabetes.

    Effects of grazing disturbance on the soil carbon contents and active components in the four vegetations, i.e., artificial Robinia pseudoacacia plantation, artificial poplar plantation, Berberis aggregate shrubland and grassland, were studied in the mountain forest-arid valley ecotone in the upper Minjiang River. Soil organic carbon and active component contents in 0-10 cm soil layer were greater than in 10-20 cm soil layer at each level of grazing disturbance. With increasing the grazing intensity, the total organic carbon (TOC), light fraction organic carbon (LFOC), particulate organic carbon (POC) and easily oxidized carbon (LOC) contents in 0-10 cm soil layer decreased gradually in the artificial R. pseudoacacia plantation. The LFOC content decreased, the POC content increased, and the TOC and LOC contents decreased initially and then increased with increasing the grazing intensity in the artificial poplar plantation. The POC content decreased, and the TOC, LFOC and LOC contents decreased initially and then increased with increasing the grazing intensity in the B. aggregate shrubland. The POC and TOC contents decreased, and the LFOC and LOC contents decreased initially and then increased with increasing the grazing intensity in the grassland. The decreasing ranges of LOC, LFOC and POC contents were 0.1-7.9 times more than that of TOC content. There were significant positive relationships between TOC and LOC, LFOC and POC, suggesting that the active organic carbon components could reflect the change of soil total carbon content.

    Full Text Available Abstract Traditional plant use in Nepal has been documented for millennia. The importance of plants as medicine has not diminished in any way in recent times, and traditional medicines are still the most important health care source for the vast majority of the population. This paper examines the ethnobotany and traditional use of plants extracted from the vulnerable alpine zone in the Dolpa, Humla, Jumla and Mustang districts of Nepal. The results of this ethnobotanical study indicate that a very large number of plant species is used as traditional medicines. There were 107, 59, 44 and 166 species of ethnomedicinal importance in surveyed areas of Dolpa, Humla, Jumla and Mustang district respectively. Of these, 84 common species, used at least in two districts, were selected to enumerate their ethnomedicinal properties. The 84 species belonged to 75 genera and 39 families. The commonest species in this pharmacopoeia were: Allium wallichii, Cordyceps sinensis, Dactylorhiza hatagirea, and Rheum australe. A total of 21 species were most common in three districts and 59 in two districts. The genera Aconitum, Allium, Arisaema, Berberis, Corydalis, Gentiana, Hippophae, Juniperus and Rhododendron each possessed two species with ethnomedicinal use. Labiatae was the most medicinally important family with five species used, followed by Araceae, Compositae, Liliaceae, Polygonaceae, Ranunculaceae, Scrophulariaceae and Umbelliferae, each contributing four species.

    The development of a fast hCCC method tailored to recover phenolics of Siberian barberry (Berberis sibirica, Berberidaceae) responsible for the observed strong antioxidant activity was performed. Initially, the optimization of extraction procedure was evaluated based on the antiradical potential assessment (DPPH and Folin-Ciocalteu assays). 100 °C methanol ASE extract exhibited the highest antiradical activity (IC50=60 ± 4 μg/mL), and a significant TPC (159 ± 2 mgGAE/g). Thorough determination of phenolic content by UHPLC-DAD-ESI(-)HRMS revealed the presence of 10 phenolics as major constituents, and several groups of alkaloids. pH-zone refining hCCC was chosen as the most promising method for the extract's fractionation due to the ionizable character of its constituents. For this purpose a MtBE-H2O (1:1) system with 10mM TEA and HCl was applied leading to a phenolic fraction, free of alkaloids, with higher antioxidant capacity (IC50=25 μg/mL, TPC=178 mg GAE/g). Additionally, fractionation of alkaloids was achieved resulting isolation of pharmacologically important alkaloids: magnoflorine and berberine.

    The multi-drug resistance offered by Carbapenem Resistant Escherichia coli (Family: Enterobacteriaceae; Class: Gammaproteobacteria) against third line antibiotics can be attributed towards its ability to develop biofilm. Such process involves adhesion and quorum-sensing induced colonization leading to biomass development. The present study explored the anti-adhesion, anti-quorum sensing and anti-biofilm potential of 05 pre-standardized potent herbals. Berberis aristata (PTRC-2111-A) exhibited maximum potential in all these activities i.e. 91.3% ± 0.05% (Anti-adhesion), 96.06% ± 0.05% (Anti-Quorum sensing) and 51.3% ± 0.07% (Anti-Biofilm formation) respectively. Camellia sinensis (PTRC-31911-A) showed both anti-adhesion (84.1% ± 0.03%) and anti-quorum sensing (90.0%) potential while Holarrhena antidysenterica (PTRC-8111-A) showed only anti-quorum sensing potential as compared to standards/antibiotics. These findings were in line with the molecular docking analysis of phytoligands against Lux S and Pilin receptors. Furthermore, the pairwise correlation analysis of the tested activities with qualitative, quantitative and bioactivity functional descriptors revealed that an increased content of alkaloid, moderate content of flavonoids and decreased content of tannins supported all the three activities. In addition, nitric oxide and superoxide scavenging activity were found to be correlated with anti-quorum sensing activity. The findings indicated clearly that B. aristata (Family: Berberidaceae) and C. sinensis (Family: Theaceae) were potent herbal leads with significant therapeutic potential which further needs to be explored at pre-clinical level in the future.

Basic research in diabetes is endeavoring to identify new actives working as insulin savers, use of which could delay the introduction of injectable insulin or reduce the insulin dose needed. Commonly available as a nutraceutical, berberine is a potential candidate.Methods and results: Because its low oral bioavailability can be overcome by P-glycoprotein inhibitors like herbal polyphenols, we have tested the nutraceutical combination of Berberis aristata extract and Silybum marianum extract (Berberol® in type 2 diabetes in terms of its additive effect when combined with a conventional oral regimen for patients with suboptimal glycemic control. After 90 days of treatment, the nutraceutical association had a positive effect on glycemic and lipid parameters, significantly reducing glycosylated hemoglobin, basal insulin, homeostatic model assessment of insulin resistance, total and low-density lipoprotein cholesterol, and triglycerides. A relevant effect was also observed in terms of liver function by measuring aspartate transaminase and alanine transaminase. The product had a good safety profile, with distinctive gastrointestinal side effects likely due to its acarbose-like action.Conclusion: Although further studies should be carried out to confirm our data, Berberol could be considered a good candidate as an adjunctive treatment option in diabetes, especially in patients with suboptimal glycemic control.Keywords: berberine, silymarin, glycosylated hemoglobin, diabetes

  7. Report details poverty-population-environment link.

    This summary reports on the state of environmental conditions in 1993 and is a reprint from an ICPD publication. This summary refers to a Roundtable Meeting held in November 1993, preliminary to the 1994 UN Conference on the Environment and Development, and an environmental report by Mary Berberis. The report identifies five regions with serious environmental degradation and resource depletion (the Bay of Bengal; the former forested uplands of Indonesia, Nepal, the Philippines, and Thailand; the forests of Central America; the arid regions of sub-Saharan Africa; and the small South Pacific island states). These regions are not just beset with environmental problems, but those problems are exacerbated by problems with land supply and use, poverty, waste, and lack of technology. The report emphasizes that a focus solely on population growth issues obscures the urgent demand for dealing with poverty alleviation, land reform, waste reduction, and improved technologies. Environmental degradation is also caused to a great extent by unsustainable patterns of consumption by affluent groups and by the processes of urban expansion, deforestation, and cultivation of marginal lands in both developed and developing countries. Mary Barberis in her summary of the literature on the causes of environmental conditions considers that the most serious environmental damage is generated by conditions of poverty and population pressure. Environmentally unsound practices are supported by inappropriate farming and soil management techniques, unequal access to resources, and government policies. The example of Bangladesh illustrates that urban population growth has occurred mostly in poor areas, and the problems of water supply, drainage, solid waste disposal, and sanitation are compounded by population growth. Rivers and marine fisheries is contaminated by urban discharges, untreated industrial waste, and fertilizers. Increased salinization degrades the land. Harvesting of wood depletes

    Citizen science is commonly cited as an effective approach to expand the scale of invasive species data collection and monitoring. However, researchers often hesitate to use these data due to concerns over data quality. In light of recent research on the quality of data collected by volunteers, we aimed to demonstrate the extent to which citizen science data can increase sampling coverage, fill gaps in species distributions, and improve habitat suitability models compared to professionally generated data sets used in isolation. We combined data sets from professionals and volunteers for five invasive plant species (Alliaria petiolata, Berberis thunbergii, Cirsium palustre, Pastinaca sativa, Polygonum cuspidatum) in portions of Wisconsin. Volunteers sampled counties not sampled by professionals for three of the five species. Volunteers also added presence locations within counties not included in professional data sets, especially in southern portions of the state where professional monitoring activities had been minimal. Volunteers made a significant contribution to the known distribution, environmental gradients sampled, and the habitat suitability of P. cuspidatum. Models generated with professional data sets for the other four species performed reasonably well according to AUC values (>0.76). The addition of volunteer data did not greatly change model performance (AUC > 0.79) but did change the suitability surface generated by the models, making them more realistic. Our findings underscore the need to merge data from multiple sources to improve knowledge of current species distributions, and to predict their movement under present and future environmental conditions. The efficiency and success of these approaches require that monitoring efforts involve multiple stakeholders in continuous collaboration via established monitoring networks.

    Full Text Available Herbal extracts have been successfully used in dentistry as tooth cleaning and antimicrobial plaque agents. The aim of this study was to evaluate the clinical effects of a dental gel containing barberry extracts (from Berberis vulgaris on gingivitis and microbial plaque control. A double blind clinical trial study was conducted in a dormitory on 45 boys aged 11-12 years having the same socioeconomic conditions. These students were divided into 3 groups; the first group (25 students using barberry gel, and the second group (10 students using placebo gel without active ingredient. To compare the activity of our gel with an active antiplaque, a third group of 10 students using Colgate® antiplaque toothpaste was also considered. At the beginning all subjects were examined for plaque index (PI and gingival index (GI. These tests were re-evaluated after 21 days of using the above mentioned dentifrices. The results showed that barberry gel has reduced the PI for about 56%. This reduction was 18.5% for placebo and 44% for Colgate® antiplaque groups. Considering means of PI (PI and GI (GI of different groups, there was significant difference between barberry and placebo gel’s groups and between placebo and Colgate® groups, but the difference between barberry and Colgate® groups was not significant. This study indicates that the barberry dental gel effectively controls microbial plaque and gingivitis in the school aged children; therefore, the use of barberry dental gel is strongly recommended.

    Berberine, an alkaloid derivative extracted from numerous plants of the general Berberis and Coptis, has been reported to have immunomodulatory effects against immune-mediated disorders in emerging studies. In this study, the effects of berberine and its underlying molecular mechanisms were investigated from the myosin-induced myocardial injury in rats. Lewis rats were immunized with porcine cardiac myosin to induce experimental autoimmune myocarditis (EAM), treated with berberine and specific JAK inhibitor AG490 as a positive control. Our data showed that both berberine and AG490 significantly reduced the impaired cardiac function and the pathophysiological severity, impeded high levels of anti-cardiac myosin antibody of EAM rats. Th17 and Th1 cells as well as their cytokines IL-17 and IFN-γ were up-regulated in EAM. However, the excessive increase of Th17/Th1 responses was restored by berberine and AG490. We also examined the expression level of phosphorylated proteins of JAK-STAT pathway which has a key role in the Th17 and Th1 lineage commitment. The phosphorylated (p)-STAT1,STAT3 and STAT4 increased significantly in EAM, while berberine notably attenuated their excessive expression. This effect of berberine was equivalent to that of AG490 blockade. Our current study demonstrated that berberine could ameliorate EAM and the underling mechanisms may be due to the fact that berberine differentially modulates the activities of p-STAT1, p-STAT3 and p-STAT4 to suppress Th17 and Th1 cell differentiation.

    Introduction: The incidence of cardiovascular diseases (CVDs) is very high in human societies and their prevention and treatment are the most important priority in many countries. Hypertension makes an important contribution to the development of CVDs. Objectives: This study aimed to collect the ethno-medicinal knowledge of the traditional healers of Shiraz on medicinal plants used in the treatment of hypertension. Materials and Methods: Ethno-medicinal data were collected from September 2012 to July 2013 through direct interview. Twenty-five healers were interviewed using semi-structured questionnaires and their traditional ethno-medicinal knowledge was recorded. Questionnaires were included apothecary personal information, plant local name, plant parts used, method of preparation, season of harvest and traditional use. Data collected from surveys and interviews were transferred to Microsoft Excel 2007 and analyzed. Results: Analysis of data showed that, 27 medicinal plants from 22 families are used for the treatment of hypertension. The families with most antihypertensive species were Apiaceae (8%), Rosaceae (8%) and Papaveraceae (8%). The most frequently used plant parts were leaves (36%) followed by fruits (30%), aerial part (17%) and branches (7%). The most frequently used preparation method was decoction (95%). Borago officinalis (51.85%), Berberis vulgaris (51.58%) had the highest frequency of mention. Conclusion: The ethno-medicinal survey of medicinal plants recommended by traditional healers for the treatment of hypertension provides new areas of research on the antihypertensive effect of medicinal plants. In the case of safety and effectiveness, they can be refined and processed to produce natural drugs. PMID:27689107

    have the signiifcant change, especially for Sorbaria kirilowii andBerberis diaphana. The former species has shorter grow season for later spring phenophase and earlier autumn phenophases, reaching 15.49 d ∙ a−1, and for the later species, the whole phenological period delay.Discussion The result of regional climate change in this research is similar with the former research result, namely have the same change tendency of increase in temperature and decrease in precipitation. However, because Xinglongshan National Natural Reserve is located at the Qinghai, Tibet and Mengxin Plateau, the coastal area of these plateaus, affected by the factors such as topography, its temperature change rate is a bit slow than the average rate in China. What is more, the research scope, Yuzhong County is located in the southeast of Lanzhou City, the southern part of Gansu Province, where is in the scale that arid and semi-arid move to south, and the annual precipitation decreased. The change pattern of phenophases is identical with the former research in northern part of China from 1982 — 1999. Sorbaria kirilowii andBerberis diaphana show different change tendency and response to regional climate change because its own characteristics, especially the cold tolerance of the later one.Conclusions The regional climate change in Xinglongshan National Natural Reserve have the tendency of increasing in temperature and decrease in precipitation, which is similar with most former study on relative area, and the change of phenophases of 14 observed plants, also the dominant plants in this study area, showing the tendency of delaying or in advance because of own characters. There are two plants, namelySorbaria kirilowii andBerberis diaphana, showing significant change among 14 observations. The former one has a shorter growing season caused by higher temperature and less precipitation, while the later one has the tendency of delaying on all kinds of phenophases because of its better resistant ability against cold.

    Full Text Available Exotic plant invasions and chronic high levels of herbivory are two of the major biotic stressors impacting temperate forest ecosystems in eastern North America, and the two problems are often linked. We used a 4-ha deer exclosure maintained since 1991 to examine the influence of a generalist herbivore, white-tailed deer (Odocoileus virginianus, on the abundance of four exotic invasive (Rosa multiflora, Berberis thunbergii, Rubus phoenicolasius and Microstegium vimineum and one native (Cynoglossum virginianum plant species, within a 25.6-ha mature temperate forest dynamics plot in Virginia, USA. We identified significant predictors of the abundance of each focal species using generalized linear models incorporating 10 environmental and landscape variables. After controlling for those predictors, we applied our models to a 4-ha deer exclusion site and a 4-ha reference site, both embedded within the larger plot, to test the role of deer on the abundance of the focal species. Slope, edge effects and soil pH were the most frequent predictors of the abundance of the focal species on the larger plot. The abundance of C. virginianum, known to be deer-dispersed, was significantly lower in the exclosure. Similar patterns were detected for B. thunbergii, R. phoenicolasius and M. vimineum, whereas R. multiflora was more abundant within the exclosure. Our results indicate that chronic high deer density facilitates increased abundances of several exotic invasive plant species, with the notable exception of R. multiflora. We infer that the invasion of many exotic plant species that are browse-tolerant to white-tailed deer could be limited by reducing deer populations.

    Phenotypic plasticity in morphophysiological leaf traits in response to wind was studied in two dominant shrub species of the Patagonian steppe, used as model systems for understanding effects of high wind speed on leaf water relations and hydraulic properties of small woody plants. Morpho-anatomical traits, hydraulic conductance and conductivity and water relations in leaves of wind-exposed and protected crown sides were examined during the summer with nearly continuous high winds. Although exposed sides of the crowns were subjected to higher wind speeds and air saturation deficits than the protected sides, leaves throughout the crown had similar minimum leaf water potential (ΨL). The two species were able to maintain homeostasis in minimum ΨL using different physiological mechanisms. Berberis microphylla avoided a decrease in the minimum ΨL in the exposed side of the crown by reducing water loss by stomatal control, loss of cell turgor and low epidermal conductance. Colliguaja integerrima increased leaf water transport efficiency to maintain transpiration rates without increasing the driving force for water loss in the wind-exposed crown side. Leaf physiological changes within the crown help to prevent the decrease of minimum ΨL and thus contribute to the maintenance of homeostasis, assuring the hydraulic integrity of the plant under unfavorable conditions. The responses of leaf traits that contribute to mechanical resistance (leaf mass per area and thickness) differed from those of large physiological traits by exhibiting low phenotypic plasticity. The results of this study help us to understand the unique properties of shrubs which have different hydraulic architecture compared to trees.

    In evergreen plants, old leaves may contribute photosynthate to initiation of shoot growth in the spring. They might also function as storage sites for carbohydrates and nitrogen (N). We hence hypothesized that whole-plant allocation of carbohydrates and N to storage in stems and roots may be lower in evergreen than in deciduous species. We selected three species pairs consisting of an evergreen and a related deciduous species: Mahonia aquifolium (Pursh) Nutt. and Berberis vulgaris L. (Berberidaceae), Prunus laurocerasus L. and Prunus serotina Ehrh. (Rosaceae), and Viburnum rhytidophyllum Hemsl. and Viburnum lantana L. (Adoxaceae). Seedlings were grown outdoors in pots and harvested on two dates during the growing season for the determination of biomass, carbohydrate and N allocation ratios. Plant size-adjusted pools of nonstructural carbohydrates in stems and roots were lower in the evergreen species of Berberidaceae and Adoxaceae, and the slope of the carbohydrate pool vs plant biomass relationship was lower in the evergreen species of Rosaceae compared with the respective deciduous species, consistent with the leading hypothesis. Pools of N in stems and roots, however, did not vary with leaf habit. In all species, foliage contained more than half of the plant's nonstructural carbohydrate pool and, in late summer, also more than half of the plant's N pool, suggesting that in juvenile individuals of evergreen species, leaves may be a major storage site. Additionally, we hypothesized that concentration of defensive phenolic compounds in leaves should be higher in evergreen than in deciduous species, because the lower carbohydrate pool in stems and roots of the former restricts their capacity for regrowth following herbivory and also because of the need to protect their longer-living foliage. Our results did not support this hypothesis, suggesting that evergreen plants may rely predominantly on structural defenses. In summary, our study indicates that leaf habit has

    The developmental activities, particularly the construction of hydroelectric projects are causing a great loss of biodiversity in the Indian Himalayan Region. The Himachal Pradesh, a part of IHR is well known for the development of hydroelectric projects.The Parbati H.E. Project is amongst the major projects of the State. The different stages of the project are all causing loss of biodiversity of the area.Stage Ⅲ of the Parbati H.E. Project is a run of the river scheme on the Sainj River downstream of Power House of Parbati H.E. Project Stage Ⅱ. The project shall utilize regulated discharge of Parbati H.E.Project Stage Ⅱ and inflow of River Sainj for power generation, and has been contemplated as a peaking station operating in tandem with Stage Ⅱ. The present study has been undertaken to see the impact of hydroelectric project on the biodiversity, particularly on medicinal plants. A total of 104 species of medicinal plants, belonging to different life forms, i.e.,trees (23 spp.), shrubs (22 spp.), herbs (57 spp.) and ferns (2 spp.) were recorded. The species have been analyzed and studied for their distribution,classification, altitudinal zones, part (s) used,indigenous uses, nativity, endemism and rarity.Different parts of these species, such as whole plants,roots (including rhizomes and tubers), leaves, flowers,fruits, seeds, stems, barks, spikes, nuts and insect galls are used by the inhabitants for curing various diseases and ailments. 30 species are native to the Himalayan region, 9 species native to the Himalayan region and adjacent countries also and 65 species are non-natives. 9 species are near endemics. Considering the whole Himalaya as a biogeographic unit (sensu lato),the near endemics are endemic to the Himalaya.Among these species, Zanthoxylum armatum is categorized as Endangered and Valeriana wallichii as Vulnerable.

    Ethnopharmacological relevance Berberine is an isoquinoline alkaloid isolated from the root and bark of plants such as goldenseal, Berberis, and Chinese goldthread. Berberine-containing crude drugs have been used as an antimicrobial remedy against gastrointestinal infections for thousands of years. It is also widely used in Asian countries for diabetes, hypertension, and hypercholesterolemia therapy. Aim of the Study Potential drug-drug interactions are of concern because of the wide usage of berberine. A few studies have reported interactions between berberine and cytochromes P450 (CYPs) in vitro, but little is known about whether berberine influences CYPs in vivo, especially after repeated administration. In this study, eight-week-old male C57BL/6 mice were given berberine orally (0,10, 30, 100, 300 mg/kg, i.g., daily for 14 days), and the effect of berberine on over 20 major Cyps and related nuclear receptors in mice livers were examined at both the mRNA and enzyme activity levels. Results In general, liver function of mice treated with various doses of berberine had no significant change, and repeated oral administration of the 3 lower doses of berberine for 14 days did not affect the expression of genes examined. However, after the highest dose of berberine (300 mg/kg), Cyp3a11 and Cyp3a25 mRNA decreased 67.6 and 87.4%, respectively, whereas Cyp1a2 mRNA increased 43.2%, and enzyme activities of Cyp3a11 and Cyp2d22 decreased 67.9 and 32.4%, respectively. Cyp2a4, 2b10 and Cyp2c29 were not altered at both mRNA and enzyme activity levels. Conclusions If studies in mice extrapolate to humans, lower doses of berberine appear to present a low risk of producing drug-drug interactions as a result of changed Cyp enzyme activity. However, high doses of berberine may suppress Cyp activities and result in drug-drug interactions. PMID:21920422

    A high degree of virulence diversity has been maintained in the population ofPuccinia graminis f. sp.tritici (Pgt) in northwestern United States. AlthoughBerberis vulgaris is present in the region andPgthas been isolated from aecial infections onB. vulgaris, the population is too diverse to be explained by the limited presence ofB. vulgaris alone. Since 2008, we have isolatedP. graminis from aecial infections on fruits ofMahonia repens andMahonia aquifolium from northwestern United States. These two native woody shrub species, widely distributed in western North America, were once classiifed as resistant to P. graminis based on artiifcial inoculations. By isolatingP. graminis from aecia, we established that M. repens andM. aquifolium along withB. vulgaris (albeit infrequent) serve as the alternate hosts ofP. graminis in the region. The isolates ofP. graminis from Mahonia of North America had diverse virulence patterns and most of the isolates could be differentiated on Morocco, Line E, Chinese Spring, Little Club, LMPG-6, Rusty, and other genotypes that are considered to be universally susceptible to mostPgt isolates. This discovery explained the persistence of virulence diversity ofPgt observed in isolates derived from uredinia on cereal crops in the region. In addition to cereal crops, uredinial stage of theP. graminis population is sustained by wild grasses, especiallyElymus glaucus, a native grass sharing the same habitat with the rusted Mahonia spp. Although virulence to some important stem rust resistance genes was observed in some isolates derived from Mahonia of North America when tested against single stem rust resistance gene stocks, the overall virulence is very limited in these isolates. This is likely a result of limited selection pressure on the rust population. In contrast to northwestern United Sates, thePgt population in east of the Rocky Mountains of North America has declined steadily with a single race, QFCSC, being predominant in the last

    Full Text Available Glioblastoma (GBM is the most common primary brain tumor, accounting for approximately 40% of all central nervous system malignancies. Despite standard treatment consisting of surgical resection, radiotherapy and/or chemotherapy, the prognosis for GBM is poor; with a median survival of 14.6 months. The cancer stem cell or cancer-initiating cell model has provided a new paradigm for understanding development and recurrence of GBM following treatment. Berbamine (BBM is a natural compound derived from the Berberis amurensis plant, and along with its derivatives, has been shown to exhibit antitumor activity in several cancers. Here, we reported that a novel synthetic Berbamine derivative, BBMD3, inhibits cell viability and induces apoptosis of cancer stem-like cells (CSCs in a time- and dose-dependent manner when the CSCs from four GBM patients (PBT003, PBT008, PBT022, and PBT030 were cultured. These CSCs grew in neurospheres and expressed CD133 and nestin as markers. Treatment with BBMD3 destroyed the neurosphere morphology, and led to the induction of apoptosis in the CSCs. Induction of apoptosis in these CSCs is dependent upon activation of caspase-3 and cleavage of poly (ADP-ribose polymerase (PARP. MicroRNA-4284 (miR-4284 was shown to be over-expressed about 4-fold in the CSCs following BBMD3 treatment. Furthermore, transfection of synthetic anti-sense oligonucleotide against human miR-4284 partially blocked the anticancer effects of BBMD3 on the GBM derived CSCs. BBMD3 also increased phosphorylation of the c-Jun N-terminal kinase (JNK/stress-activated protein kinase (SAPK, resulting in an increase expression of phosphorylated c-Jun and total c-Fos; the major components of transcriptional factor AP-1. The JNK-c-Jun/AP-1 signaling pathway plays an important role in the induction of apoptosis in response to UV irradiation and some drug treatments. Targeting glioblastoma stem-like cells with BBMD3 is therefore novel, and may have promise as an

    Full Text Available Introduction. Biologically active substances (BAS of barberry roots represented by alkaloids of isoquinoline group are perspective substances for development of preparations with multiple pharmacological activities. However, now manufacture of them in Ukraine is stopped. One of the reasons of this is out-of-date production technologies of alkaloids involving use of toxic and/or flammable solvents. In the article possibility for application of liquefied gases in technology of obtaining of alkaloids from barberry roots has been studied. Materials and methods. Initial raw herb drug were barberry (Berberis vulgaris roots harvested in spring on the territory of Southern Ukraine. Their moisture content was 11%, comminuting degree was 0,5-1,4 mm. At the first stage purification of raw herb drug from lipophilic impurities (defatting was made with use of some liquefied gases: tetrafluoroethane, isobutane, difluorochloromethane and difluoromethane. Extraction of the alkaloid sum was made with difluoromethane mixed with various quantities of liquid ammonia or diethylamine as alkaline agent. Crude extracts were exposed to two-level liquefied-gas purification. At first the alkaloid bases were transformed into saline forms with aqueous solutions of acids and purified from ballast impurities with liquefied freon-22. Then alkaloid salts were reextracted from aqueous phase in the base form with liquefied mixture of difluoromethane and ammonia. Mixing of liquid phases was provided by creation of alternate gradients of temperatures and, as consequence, pressures between separators feeding alternately cool water into jacket of one of them, and warm water – into jacket of another one. Quantity of lipophilic ballast impurities and also weight of extractives were determined gravimetrically. Quantitative analysis of the alkaloid sum was made by titrimetric method after sedimentation of alkaloids with volumetric solution of phosphomolybdic acid. Results and discussion

    Invasive plant species can have profound negative effects on natural communities by competively excluding native species. Berberis thunbergii (Japanese barberry), Frangula alnus (glossy or alder buckthorn) and Lythrum salicaria (purple loosestrife) are invasive species known to reduce native plant diversity and are thus of great concern to Acadia National Park. Pollinators visit them for nectar and pollen. The effects of invasive plant species on pollinator behavior were investigated by comparing pollinator visitation to co-flowering native and invasive species with visitation to native species growing alone. The effect of invasives on pollination of native plants was studied by comparing fruit set in patches of the native species growing near invasives with patches far from invasive species in Acadia National Park. The coflowering pairs were as follows: in the spring native Vaccinium angustifolium (lowbush blueberry) was paired with B. thunbergii; in early summer native Viburnum nudum (wild raisin) was paired with F. alnus ; in late summer native Spiraea alba (meadowsweet) was paired with L. salicaria. We investigated whether these invasives competed with native plants for pollinators in Acadia and thus negatively affected native plant reproduction. Our objectives were to determine: 1) the influence, if any, of each invasive on pollinator visitation to a co-flowering native species, 2) factors that might affect visitation, 3) invasive pollen transfer to native plants, and 4) whether invasives influence native plant reproduction (fruit set). Our findings indicate that at times the number of flower visitors to natives was lower or the species composition of visitors different when invasives were present, that invasives sometimes attracted more pollinators, that generally the invasives were more rewarding as far as nectar and pollen availability for pollinators, and that generally native plant fruit set and seed set was not significantly lowered in the presence of

    Background Clinical research encompasses a wide variety of disciplines. Traditional Chinese medicine (TCM) and natural product research have made great contributions to preventing and treating illness. The number and content of original research reports evaluating TCM and natural products have not previously been described. Information in this area will identify areas of relative strength and weakness in terms of knowledge gaps with respect to clinical conditions and natural product remedies.Methods Original research reports (i.e. original articles, brief reports, and research letters) published in the Chinese Medical Journal (CMJ) from January 2000 to December 2009 evaluating TCM and other natural products were reviewed.The United Kingdom Clinical Research Collaboration (UK-CRC) Health Research Classification System was used to analyze the type of health research conducted. Further analysis on the major illnesses addressed and the major herbal components utilized was conducted.Results One hundred and seventeen original research reports involving TCM or other natural products were identified,comprising 3.82% of the CMJ output in the period covered by this study. Of the different materia medica described in these reports, 74.4% were derived exclusively from plant material, 10.3% from animals, 3.4% from fungi, 1.7% from minerals, and 10.3% were of mixed (plant / animal / fungal / mineral) composition. Twelve herbs were investigated exclusively or were constituents of 66/87 (75.9%) of the plant-based materia medica investigated. Panax ginseng was the most commonly investigated herb or constituent (14/87, 16.1%), followed by Astragalus membranaceus (9/87, 10.3%),Coptis chinensis/Berberis spp. (7/87, 8.0%) and Rheum spp. (7/87, 8.0%). Four UK-CRC health categories accounted for the majority of TCM and other natural product research (cancer, 20.9%; cardiovascular, 19.2%; oral/gastrointestinal,9.8%; and inflammatory/immune, 9.0%). The most common research activity was

    gastro-intestinal, parasitic and hepatobiliary complaints (0.90). Berberis lycium Ajuga bracteosa, Prunella vulgaris, Adiantum capillus-veneris, Desmodium polycarpum, Pinus roxburgii, Albizia lebbeck, Cedrella serrata, Rosa brunonii, Punica granatum, Jasminum mesnyi and Zanthoxylum armatum were the most valuable plants with the highest UV, RFC and relative importance values. The Pearson correlation coefficient between UV and RFC (0.881) reflects a significant positive correlation between the use value and relative frequency of citation. The coefficient of determination indicated that 77% of the variability in UV could be explained in terms of RFC. Conclusion Systematic documentation of the medicinal plants in the Toli Peer National Park shows that the area is rich in plants with ethnomedicinal value and that the inhabitants of the area have significant knowledge about the use of such plants with herbal drugs commonly used to cure infirmities. The results of this study indicate that carrying out subsequent pharmacological and phytochemical investigations in this part of Pakistan could lead to new drug discoveries. PMID:28192466

    önemin tarihi, coğrafi ve sosyo-kültürel özelliklerini günümüze ulaştırması bakımından önemli işlevlere sahiptirler. Öte yandan, seyahat ya da seyyahlık, İslam kültüründe Müslümanların bilgi ve deneyimlerini genişletmeleri açından iyi bir gelenek olarak benimsenmiştir. Bu yüzden İslam dünyasında meşhur seyyahlar yetişmiştir. Bilindiği gibi Müslüman seyyahların en meşhuru, Şemseddin (1304–1368 olarak da bilinen İbn Battûta’dır. O, Berberi-Faslı Müslüman bir seyyahtır ve gezdiği yerleri seyahatnamesinde anlatmaktadır. İbn Battuta otuz yıllık bir süre içinde, İslam dünyasının pek çok yerini olduğu kadar, Müslüman olmayan yerleri de gezmiş, Kuzey Afrika, Batı Afrika, Güney Avrupa, Doğu Avrupa, Güney Asya, Orta Asya ve Çin’e değin pek çok yeri gezmiştir. Bu gezileriyle, yakın-çağdaşı Morco Polo’nun üç katı yere seyahat ederek onu geçmiştir. Bu yüzden İbn Battuta, tüm zamanların en büyük seyyahı olarak kabul edilir. Dindar bir kişi olarak İbn Battûta, seyahatleri boyunca, gittiği yerlerin dini özelliklerini ve dini grupları öğrenmeye büyük özen göstermiş; din adamları ve dini gruplarla sıkı ilişkiler kurmuş, ayrıca dini otoriteleri ziyaret ederek onlardan bilgiler aktarmıştır. Bunlarla da yetinmeyen İbn Battûta, gezdiği yerler hakkında Hz. Peygamber’den rivayet edilen hadisler var ise onları da zikretmiştir. Bu nedenle onun seyahatnamesi, dönemindeki ortaçağ İslam coğrafyasını, sosyo-kültürel ve ekonomik özelliklerini olduğu kadar, dönemin Müslümanlarının yaşamları, uygarlık düzeyleri ve Hz. Muhammed’in mekânlara, kişilere ve Müslüman yaşamına ilişkin olarak söylediği sözleri anlamamıza da katkılar sağlayacak niteliktedir. Şu halde, İbn Battuta’nın çalışmaları, hadis ve sünnet açısından da önemli bir kaynak durumundadır.

    Tibetan medicinal industry is one of six major pillar industries in Tibet autonomous region. The rare and endangered plants are increasingly and widely used in Tibetan medicinal industry; however, there has been lack of a clear understanding of these resources and their reasonable applications. In this study, the rare and endangered Tibetan medicinal plants distributed in the Linzhi region of Tibet were analyzed by the plot-quadrat method, walking and inquiry ways. In the investigation, 153 sample plots (30m×30m) and 1,377 quadrats (2m×2m) were set up in 51 typical sites, covering a total plot area of 137,700 m^2. Results show that there were 35 species of rare and endangered plants, pertaining to 23 families and 33 genera in the Linzhi region. The ratio of species was high, and it was an epitome of plants distribution in Tibet. The moisture content of aerial part was higher than that of underground part in many plants except for Codonopsis convolvulacea, Mirabilis himalaica, Polygonatum cirrhifolium, Asparagus filicinus, Pterocephalus hooked, Phlomis younghusbandii and Bupleurum marginatum var. stenophyllum. The mean biomass of Berberis Agricola was highest (1,800 g) and the lowest one was only 0.699 g for Polygonatum cirrhifolium. The biomass of aerial part was 14 times that of underground part for Herpetospermum pedunculosum, the ratio was the maximum, and the minimum ratio of them was 0.189 for Asparagus filicinus. Variations in biomass of aerial part, underground part, and the whole plant were similar for Polygonatum cirrhifolium, Halenia elliptica, Bupleurum marginatum var. stenophyllum and Veronica L. in the same latitude, but changes in the biomass showed different features, determined by plant height and density. The resources reserves of the rare and endangered plants were estimated to be 3,199.29 t in the Linzhi region. The biomass in unit area was closely related to altitude. Rare and endangered plants showed characteristics of abundant
