C-glucoside flavonoids from the leaves ofCrataegus pinnatifidaBge. var.majorN.E.Br.

Two new acetyl C-glucoside flavonoids, 8-C-beta-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.
