摘要
目的:对民族药四方藤的化学成分进行研究。方法:采用硅胶柱层析对四方藤乙酸乙酯部位的化学成分进行分离,根据化合物的理化性质和波谱数据鉴定其结构。结果:从四方藤中的乙酸乙酯部位分离得到5个甾体类化合物和2个三萜类化合物,分别鉴定为:豆甾醇(1)、豆甾醇乙酸酯(2)、△5.22-豆甾醇-3—0-/3-D-葡萄糖苷(3)、β-谷甾醇(4)、胡萝b苷(5)、蒲公英赛酮(6)、齐墩果酸(7)。结论:除化合物4、5外,其余化合物均为首次从该植物中分离得到,其中,化合物1~3为首次从该属植物中分离得到。
Objective : To study the chemical constituents of ethnical drug Cissus pteroclada. Methods : Silica gel column chromatography was employed to separate the constituents from EtOAc extraction of Cissus pteroclada and their structures were identified by physi- cochemical properties as well as spectrum analysis. Results: Five steroidal compounds and 2 triterpenoid constituents were ob- tained. Their structures were identified as : stigmasterol ( 1 ), stigmasterol acetate ( 2 ), stigmasta-5, 22-dien-3-O-/3-D-glucopyranoside ( 3 ) , /3-sitosterol (4), daucousterol ( 5 ) , taraxerone (6), oleanolic acid ( 7 ). Conclusion : All the compounds are isolated from this plant for the first time except for compound 4 and 5. Compounds 1 - 3 are obtained from this genus for the first time.
