Abstract:
AIM To study the chemical constituents from twigs of Trigonostemon lutescens Y.T.Chang et J.Y.Liang.METHODS The ethyl acetate fraction of 95% ethanol extract from T.lutescens twigs was isolated and purified by silica,Sephadex LH-20 and MCI column,then the structures of obtained compounds were identified by physicochemical properties and spectral data.RESULTS Ten compounds were isolated and elucidated as 3-O-acetyloleanolic acid (1),methyl 3-acetoxy-12-enly-oleanen-28-oate (2),taraxerone (3),spiciflorin (4),simiarenol (5),β-sitosterol palmitate (6),3,3',4-tri-O-methylellagic acid (7),β-sitosterol (8),stigamasterol (9),palmitic acid (10).CONCLUSION Compounds 1-6 are isolated from genus Trigonostemon for the first time,compounds 7 and 9 are first obtained from this plant.
