Abstract

Abstract A new triterpenoid 21α‐methylmelianol(21R,23R)epoxy‐24‐hydroxy‐21α‐methoxyl]triucalla‐7,25‐dien‐3‐one (1), was obtained from the fruit of Phellodendron chinense var. glabriusculum Schneid and elucidated by means of spectroscopic analysis. Niloticin and melianone type tirucallane triterpenoids were major constituents in the EtOAc fraction of crude extract of the the fruit of Phellodendron chinense var. glabriusculum Schneid.
