异叶三宝木叶的化学成分研究

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.
