中药云前胡的化学成分研究

STUDIES ON THE CHEMICAL CONSTITUENTS OF THE TRADITIONAL CHINESE MEDICINE "YUN QIAN- HU" (PEUCEDANUM RUBRICAULE SHAN ET SHCH.)

摘要: 从云前胡(Peucedanum rubricaule Shan et Shch)的乙醇提取物中分离鉴定了二十个成分,有十三个是香豆素化合物,其中化合物ⅩⅤ是一个新的香豆素配糖体,命名为云前胡甙(rubr icauloside),经光谱测定及化学降解确定其结构为:5,7-二甲氧基-8-2′-羟基-3′-甲基,3′-O-β-D-呋喃芹糖基(1→6)-β-D-吡喃葡萄糖基-丁基-香豆素。

Abstract: A new coumarin-glycoside and twelve known coumarins together with seven other known compounds have been isolated from the roots of Peucedanum rubricaule Shan et Shch. (Umbelliferae). The new coumarin-glycoside named rubricauloside, has been elucidated as 5, 7-dimethoxy-8-2′-hydroxy-3′-methyl, 3′-O-β-Dapiofuranosyl (1→6)-β-D-glucopyranosyl-butyl-coumarin by means of spectral and chemical analysis.
