摘要:

采用多种分离技术和波谱方法研究耳叶牛皮消中化学成分,从中分离鉴定13个化合物,包括C21-甾体类化合物5个:告达亭(1)、青阳参苷元(2)、萝藦苷元(3)、加加米宁(4)和开德苷元(5),苯乙酮类化合物6个:3-羟基苯乙酮(6)、4-羟基苯乙酮(7)、2,4-二羟基苯乙酮(8)、2,5-二羟基苯乙酮(9)、3,4-二羟基苯乙酮(10)和白首乌二苯酮(11),木脂素类化合物2个:(+)-松脂醇(12)和(-)-表丁香脂素(13)。化合物1213在耳叶牛皮消中为首次报道。清除DPPH和ABTS自由基活性研究表明,化合物10具有显著清除DPPH和ABTS自由基活性,其IC50分别为0.58和1.82 μg/mL。

Abstract:

Thirteen compounds isolated from the roots of Cynanchum auriculatum,which structures were determined as caudatin (1),qingyangshengenin (2),metaplexigenin (3),gagamine (4),kidjoranin (5),3-hydroxyacetophenone (6),4-hydroxyacetophenone (7),2,4-dihydroxyacetophenone (8),2,5-dihydroxyacetophenone (9),4-acetocatechol (10),baishouwubenzophenone (11),(+)-pinoresinol (12) and (-)-episyringaresinol (13) by comparison their NMR and ESI-MS data with the literature reported data.Among them,compounds 12 and 13 were isolated from this plant for the first time.All isolates were evaluated the scavenging activities on DPPH and ABTS.The results indicated that compound 10 had significant scavenging activities on DPPH and ABTS (IC50 = 0.58 and 1.82 μg/mL,respectively).
