Abstract:
Three active glycosides that afford protection to red blood cell membrane to resist hemolysis induced by a peroxyl radical initiator, 2,2'-azo-bis-(2-amidinopropane) dihydrochloride (AAPH) were isolated from the MeOH extract of Ligustrum sinense. The compounds are 10-hydroxyl-oleuropein (1), 3-O-alpha-L-rhamnopyranosyl-kaempferol-7-O-beta-D-glucopyranoside (4), and 8'-alpha-hydroxyl-lariciresinol-4'-O-beta-D-glucopyranoside (6). The structures of these glycosides were determined by 1D and 2D NMR spectral analysis.
