巧茶中木栓烷型三萜成分研究

Studies on Triterpenoid Constituents of Qiaocha (Catha exulis)

利用CO2超临界流体技术从海南产的卫矛科植物巧茶Cathaexulis茎叶中分得4个木栓烷型三萜化合物，结构都通过波谱方法进行鉴定。

Four triterpenoid with friedelane skeleton were isolated from the stems and leaves of Cathaexulis Forsk collected in Hainan Province,China. Their structures were deduced on the basis of spectroscopicdata. Supercritical CO2 fluid extraction was used in their separation.
