喙果皂帽花根的化学成分研究

摘要

为了解喙果皂帽花(Dasymaschalon rostratum)根的化学成分,采用多种色谱技术从其根的乙醇提取物中分离得到8个化合物.通过波谱数据分析,分别鉴定为:花旗松素 (1)、(+)-儿茶素 (2)、毛蕊异黄酮 (3)、(-)-丁香树脂酚 (4)、(-)-皮树脂醇 (5)、lirioresinol A (6)、N-反式肉桂酸酰对羟基苯乙胺 (7)和羟基酪醇 (8).所有化合物均为首次从该植物中获得.化合物1~8均无明显抗菌活性.%To understand the chemical constituents from Dasymaschalon rostratum, eight compounds were obtained from its roots by multiple chromatographic separation techniques. On the basis of spectral data, their structures were identified as (+)-taxifolin (1), catechin (2), calycosin (3), (-)-syringaresinol (4), (-)-medioresinol (5),lirioresinol A(6),N-trans-cinnamoyltyramine(7),and hydroxytyrosol(8).All of the compounds were isolated from this plant for the first time. Compounds 1-8 showed no obvious antibacterial activites.
