喙果皂帽花根的化学成分研究

Chemical Constituents from the Roots of Dasymaschalon rostratum

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。

Abstract:

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.
