直立百部的非生物碱化学成分研究(英文)

Non-alkaloid Constituents from Stemona sessilifolia

从直立百部(Stemona sessilifolia)根中首次分离到十四个非生物碱成分。依据波谱数据,它们鉴定为豆甾醇(1)、4-甲氧基苯甲酸(2)、苯甲酸(3)、3,4-二甲氧基苯酚(4)、4-甲氧基苯甲酸(5)、4-羟基苯甲酸(6)、4-羟基-3-甲氧基苯甲酸(7)、4-羟基-3,5-二甲氧基苯甲酸(8)、3,3′-bis(3,4-dihydro-4-hydroxy-6-methoxy)-2H-1-benzo-pyran(9)、4-羟基-3-甲氧基苯甲醛(10)、羽扇豆烷-3-酮(11)、绿原酸(12)、胡萝卜苷(13),3-feruoyl-chinasueure(14)。化合物5~14为首次从百部属植物中分离得到。

Fourteen non-alkaloid constituents were firstly isolated from the roots of Stemona sessilifolia.On the basis of the spectral data,they were determined as stigmasterol (1),4-methoxy benzoic acid (2),benzoic acid (3),3,4-dimethoxyphenol (4),4-methyl benzoic acid (5),4-hydroxy benzoic acid (6),4-hydroxy-3-methoxy benzoic acid (7),4-hydroxy-3,5-dimethoxy benzoic acid (8),3,3′-bis(3,4-dihydro-4-hydroxy-6-methoxy)-2H-1-benzopyran (9),4-hydroxy-3-methoxy benzaldehyde (10),lupan-3-one (11),chlorogenic acid (12),dau...
