From the wood of n-hexane extract of Willughbeia cochinchinensis, perform column chromatography on a normal phase silica gel with n-hexane: ethyl acetate obtained in 8 fractions. From GD-D and GD-F fractions, multiple column chromatography on silica gel was performed in combination with normal and reverse phase thin-layer chromatography, four triterpene compounds as epifriedelanol (1), taraxeryl acetate (2), ambolic acid (3) and α- amyrin (4) were isolated. Their chemical structures were determined by spectrocopic methods as well as comparing with data in the literature. These compounds were isolated for the first time from Willughbeia cochinchinensis.
