裸花紫珠的化学成分

Chemical Constituents from Callicarpa nudiflora

摘要:

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。

Abstract:

Seven compounds, luteoloside(1), dracocephaloside(2), juncein(3), euscaphic acid(4), ursolic acid(5), 2a-hydroxyursolic acid(6), and oleanolic acid(7) were isolated from the air-dried herbs of Cephalomappa nudiflora. 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.
