从异叶三宝木(Trigonostemon flavidus)叶中分离得到9个化合物,经波谱数据分析鉴定为robustic acid(1),1-[6-hydroxy-2-methoxy-2″,2″-dimethylpyrano-(5″,6″:3,4)]-2-(4’-methoxyphenyl)-1,2-ethanedione(2),3β-ursolic acid(3),(6S,7E)-6-hydroxy-4,7-megastigmadien-3,9-dione(4),3(-hydroxy-5,6-epoxy-7-megastigmen-9-one(5),(3R,6R,7E)-3-hydroxy-4,7-megastigmadien-9-one(6),loliolide(7),methyl P-coumarate(8),和methyl si-napate(9)。化合物1～7和9为首次从三宝木属(Trigonostemon)植物中分离得到。
Nine compounds were isolated from the leaves of Trigonostemon flavidus and identified as robustic acid (1), 1- [6-hydroxy-2-methoxy-2 “, 2” -dimethylpyrano- “6”: 3,4)] - 2- (4’-methoxyphenyl) -1,2-ethanedione (2), 3β-ursolic acid -megastigmadien-3,9-dione (4), 3 (-hydroxy-5,6-epoxy-7-megastigmen-9- one (5), (3R, 6R, 7E) -3-hydroxy- megastigmadien-9-one (6), loliolide (7), methyl P-coumarate (8) and methyl si-napate (9) .Compounds 1-7 and 9 were isolated from Trigonostemon for the first time .
