摘要
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 known compounds were isolated from the leaves of Trigonostemon flavidus. On the basis of spectroscopic data, their structures were identified as robustic acid （ 1 ）, 1-[ 6-hydroxy-2-methoxy-2＂, 2＂-dimethylpyrano-（ 5＂, 6＂： 3, 4 ） ] -2- （4＇-methoxyphenyl） -1,2-ethanedione （2）, 3/3-ursolic acid （ 3 ）, （ 6S, 7E） -6 -hydroxy-4,7-megastigmadien-3,9 - dione （4）, 3/3-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）, and methyl sinapate （9）. Compounds 1-7 and 9 were obtained from the genus Trigonostemon for the first time.
