摘要
Two new flavonoids,namely pinnatifida A (1) and pinnatifida B (2),along with four known compounds,vitexin(3),6″ O acetyl vitexin(4),2″ O acetyl vitexin (5) and 2″ O rhamnosyl vitexin (6),were isolated from the leaves of Crataegus pinnatifida Bge.var. major N.E.Br.Their structures were elucidated by the spectroscopic analysis and chemical evidence.Compound (4) and (5) were first isolated from the leaves of Crataegus pinnatifida Beg.var. major N.E.Br.
