Effect A Glycosidic Flavonol Isolated from Green Grass Jelly (Cyclea Barbata Miers) Leaves

A flavonoid was isolated from aqueous fraction of green grass jelly (Cyclea barbata Miers) leaf extract. On the basis of paper as well as thin layer chromatographic pattern, acid hydrolysis, and ultraviolet-visible spectrophotometric analysis, the isolate was confirmed as a 3-O-glycosidic flavonol with a hydroxyl group at C-4’ and an o-di OH of A ring at position of either 6,7 or 7,8.
