Abstract
Two new acetyl C-glucoside flavonoids, 8-C-β-D-(2″-O-acetyl)glucofuranosylapigenin and 3″-O-acetylvitexin, along with four known C-glucoside flavonoids, vitexin, 6″-O-acetylvitexin, 2″-O-acetylvitexin, and 2″-O-rhamnosylvitexin were isolated from the leaves of Crataegus pinnatifida Bge. var. major N.E.Br. Their structures were elucidated by spectroscopic means and chemical evidence.Keywords
