salvianolic acid b/ginkgo

OBJECTIVE To investigate and compare the antioxidant activities of salvianolic acid B (SalB) and Ginkgo biloba extract (EGb 761) in aqueous solution, rat microsomes and the cellular system. METHODS Superoxide anion (O2-.) was generated using xanthine/xanthine oxidase system and phenazine

OBJECTIVE To compare the effects of salvianolic acid B (Sal B) and Ginkgo biloba extract EGb 761 on beta-amyloid peptide (beta-AP) fibril formation and cytotoxicity to PC12 cells. METHODS The inhibitory effects of Sal B and EGb 761 on beta-AP1-40 fibril formation were determined by using

Six flavonoid constituents (quercetin, isorhamnetin, kaempferol, bilobetin, ginkgetin and sciadopitysin) were isolated from Ginkgo biloba leaves and determined by reversed phase HPLC using salvianolic acid B as internal standard. The column employed was Zorbax ODS (150 mm x 4 mm ID, 5 microns). The
