青钱柳植物中三萜成分的研究

Studies on the Triterpenoids of Cyclocarya paliurus (Batal.)Iljinsk

从青钱柳植物中得到三个三萜类成分,经理化常数测定和光谱分析鉴定为齐墩果酸、乌苏酸和epika-tonicacid,均系首次从该植物中分离得到。

Three triterpenes (Ⅰ～Ⅱ) were obtained from the leaves of Cyclocarya paliurus (Batal.)Iljinsk.By means of physicochemical and spectral methods,the structures of the three triterpenes were identified as oleanolic acid(Ⅰ),ursolic acid(Ⅱ)and epikatonic acid (Ⅲ) respectively.All of the three triterpenes were isolated for the first time from the plant of Cyclocarya paliurus (Batal.)Iljinsk.
