摘 要:Phytochemical investigation of the leaves of Premna microphylla Turcz led to the isolation of 13 known compounds. Based on spectroscopic and chemical evidences, their structures were identified as diosmetin (1), blumenol A (2), (3S,5R,6S,7E,9R)-5,6-epoxy-3,9-dihydroxy-7-megastigmene (3), 3β-hydroxy-5a,6a-epoxy-γ-megastigmen-9-one (4), ixerol B (5), (-)-dehydrovomifoliol (6), 3S,5R-dihydroxy-6S,7-megastigmadien-9-one (7), loliotide (8), (+)-dehydrololiolide (9), (+)-medioresinol (10), 4-oxopinoresinol (11), tormentic acid (12), and indole-3-carboxylic acid (13). Compounds 2-13 described above were isolated from this genus for the first time.对马鞭草科腐婢属植物豆腐柴的叶进行化学成分研究,从其乙醇提取物的氯仿萃取部位分离得到13个已知化合物。通过波谱手段、理化常数以及与文献对照的方法对其结构进行了鉴定,分别为香叶木素(1),布卢门醇A(2),(3S,5R,6S,7E,9R)-5,6-epoxy-3,9-dihydroxy-7-megastigmene(3),3β-hydroxy-5α,6α-epoxy-7-megastigmen-9-one(4),ixerol B(5),(–)-去氢催吐萝芙木醇(6),3S,5R-dihydroxy-6S,7-megastigmadien-9-one(7),黑麦草内酯(8),(+)-脱氢地芰普内酯(9),(+)-5'-甲氧基-松脂素(10),4-oxopinoresinol(11),委陵菜酸(12),3-吲哚-甲酸(13)。其中化合物2–13为首次从腐婢属植物中分离得到。
