摘　　要：目的研究拟缺香茶菜Rabdosia excisoides的化学成分。方法利用硅胶柱色谱法进行分离和纯化,通过谱学分析鉴定单体化合物结构。结果从拟缺香茶菜分离鉴定2个化合物,化合物Ⅰ命名为拟缺香茶菜甲素(excisoidesinA);化合物Ⅱ鉴定为齐墩果酸。结论化合物Ⅰ为首次发现的新二萜成分。Objective To study the chemical components in Rabdosia excisoides. Methods The isola-tion and purification were carried out on silica gel column chromatography, the chemical structures were determind by physico-chemical properties and spectral analysis. Results Two compounds were isolated from R. excisoides and their structures were identified, one was named as excisoidesin A （I）, a new diterpenoid and the other was a known compound, oleanolic acid （Ⅱ）. Conclusion Excisoidesin A is a new diterpenoid.
