Abstract

Background: Ginkgo is a native plant to China which is recently cultivated in Iran. The extract of the Ginkgo leaves contains FLAVONOIDs and ginkgolids and has been used pharmaceutically for a while. FLAVONOIDs of Ginkgo have been shown to have several effects which could increase blood flow of brain and limit the damage associated with ischemia also they inhibit cyclo-oxygenases and lipoxygenases activities and show antioxidant effects. The researchers showed that Ginkgo leaves flavonol glycosides varies during different seasons.Objective: The aim of the present research is study on SEASONAL VARIATION of FLAVONOIDs of GINKGO BILOBA L.ave’s cultivated in Iran by HPLC method.Methods: In this study Ginkgo leaves from 5 years old trees collected in 2005 from North of Iran and evaluated. Plant leaves were dried, milled, and extracted with a suitable solvent. For analysis of FLAVONOID aglycones in the extract, flavonol glycosides were hydrolyzed in acid medium and identified by HPLC instrument and the peaks of standard material; QUERCETIN, Kaempferol and Isorhamnetin were obtained.Results: According to our findings, FLAVONOIDs vary in amount during seasons and upper most amount was found in June Month (5.5%w/w).Conclusion: Results of our study shows a mild variation of FLAVONOIDs content in Ginkgo tree leaves during different months, also we found a high concentration of FLAVONOIDs in young tree leaves that are very higher than pharmacopeia′s standard (0.5% w/w) and these leaves are suitable for preparing of standardized extracts.
