目的研究伞花木Eurycorymbus cavaleriei茎的化学成分。方法采用硅胶、大孔树脂、RP-C18、MCI凝胶、SephadexLH-20、半制备高效液相色谱等手段对伞花木茎中的化学成分进行分离纯化,并通过波谱方法鉴定其结构。目的从伞花木茎中分离得到9个化合物,分别为(-)-lyoniresinol 3a-O-β-D-glucopyranoside(1)、(-)-异落叶松脂醇3a-O-β-D-葡萄糖苷(2)、5′-demethyl aquillochin(3)、(-)-丁香酯素(4)、水杨酸甲酯(5)、水杨酸乙酯(6)、β-谷甾醇(7)、香草醛(8)和3-oxotirucalla-7,24-dien-21-oic acid(9)。结论化合物1、2、4~9均为首次从该属植物中分离得到。
