South Khorasan Province, Iran the largest Producer of Berberis vulgaris in the world: Investigation of Tannin Content in the Fruit
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 7, Issue 6
Abstract
South Khorasan province which is located in South East of Iran, possesses a vast variety of plants enriched of pharmacological components. One of these valuable plant is barberry (Berberis vulgaris. family Berberidaceae). Considering the importance of plant Berberis vulgaris in popular medicine, we have extensively studied fruit of this plant, concentrating on tannins in this article due to biological effects such as anti-bacterial, anti-tumor and inhibitor of HIV replication. Twenty sample of barberry fruit were collected from different regions in South Khorasan Province, Iran. Total amount of tannins, condensed tannins and total phenols of twenty sample were measured. Total tannins, measured by Folin & Ciocalteu method, and the amount of the total phenols were recorded to tannic acid mg/g of extract. Total condensed phenolics content also was analysed by butanol-HCl assay. Then Statistical analysis was performed and all determinations were made in the triplicate and the values were averaged and reported along with the standard deviation. Results showed that the average rainfall has direct correlation with the amount of tannin for the time interval from March 2013 to July 2013. Meanwhile, our results showed negative correlation between average temperatures and the content of tannin for the period.
