裸花紫珠的化学成分

Chemical Constituents from Callicarpa nudiflora

从裸花紫珠(Callicarpa nudiflora Hook.ex Arn.)地上部分的乙醇提取物中分离得到了7个化合物,经波谱分析确定其结构分别为:木犀草苷(1),木犀草素-3'-O-β-D-吡喃葡萄糖苷(2),木犀草素-4'-O-β-D-吡喃葡萄糖苷(3),2α,3α,19α-三羟基-乌索-12-烯-28-酸(4),乌索酸(5),2α-羟基-乌索酸(6)和齐墩果酸(7)。其中化合物2-7为首次从该植物中分离得到。

Seven compounds, luteoloside （1）, dracocephaloside （2）, juncein （3）, euscaphic acid （4）, ursolic acid （5）, 2α-hydroxyursolic acid （6）, and oleanolic acid （7） were isolated from the air-dried herbs of Collicarpa nudiflora Hook. ex Am.. Their structures were elucidated by spectroscopic evidence （IR, NMR, MS, etc） and comparison of their spectral data with those of the literatures. Compounds 2-7 were isolated from this species for the first time.
