【摘要】 目的:研究桑科柘属植物构棘Cudrania cochinchinensis干燥根的化学成分。方法:利用各种硅胶、聚酰胺柱色谱技术进行分离纯化,根据NMR,MS等波谱分析和理化性质鉴定其化学结构。结果:从构棘95%乙醇提取物的醋酸乙酯部分分离得到6个黄酮类化合物。分别为3,5,7,4′-四羟基黄酮-7-O-(6″-乙酰基)-葡萄糖苷(1),3,5,7,4′-四羟基黄酮-7-O-葡萄糖苷(2),6-异戊烯基-5,7,2′,4′-四羟基二氢黄酮(3),6-异戊烯基-5,7,4′-三羟基异黄酮(4),1,3,5,6-四羟基酮(5),2,4,3′,5′-四羟基二苯乙烯(6)。结论:化合物1为首次从本属植物中分得,4,5为首次从本植物中分得。更多还原

【Abstract】 Objective: To study the chemical constituents from the roots of Cudrania cochinchinensis.Method: The chemical constituents of C.cochinchinensis were isolated and purified by silica gel,polyamide column chromatography,Their structures were identified on the basis of spectroscopic data.Result: Six compounds were isolated and identified.Their structures were established as 3,5,7,4″-tetrahydroxyflavanone-7-O-(6″-acetyl)-glucoside(1), 3,5,7,4′-tetra hydroxyflavanone-7-O-glucoside(2), 2′,4′,5,7-tetrahydroxy-6-prenyldihydroflavanone(3),5,7,4′-trihysdroxy-6-prenylisoflavanone(4), 1,3,5,6-tetrahydroxyxanthone(5),stilbene-2,4,3′,5′-tetraol(6).Conclusion: Compound 1 was isolated from this genus,while compounds 4 and 5 were isolated from this plant for the first time.更多还原
