BACKGROUND EGb761, a standardized Ginkgo biloba extract, has antioxidant and antiplatelet aggregation and thus might protect against atherosclerosis. However, molecular and functional properties of EGb761 and its major subcomponents have not been well characterized. We investigated the effect of EGb761 and its major subcomponents (bilobalide, kaemferol, and quercetin) on preventing atherosclero...

two new prenylated flavonoids, named scariosin (1) and isorhynchospermin (2) were isolated from the leaves of paracalyx scariosa together with kaempferol, quercetin, kaempferol 3-o- rutinoside and rutin. the structures of (1) and (2) were characterized as 8-c- prenyl- taxifolin 7,3'-dimethylether and 6-c-prenylquercetin 7,4'-dimethylether by their chemical and spectra data, respectively.
