岗梅根中一个新的三萜皂苷

摘要

目的:研究岗梅根的化学成分.方法:采用硅胶、反相硅胶、Sephadex LH-20等柱色谱法对岗梅根的化学成分进行分离纯化,应用谱学技术和化学方法鉴定化合物的结构.结果:从岗梅根中分离并鉴定了4个三萜苷类化合物:(3β)-19-hydroxy-28-oxours-12-en-3-yl β-D-glucopyranosiduronic acid n-butyl ester (1),ilexasoside A(2),Monepaloside F(3)和ilexoside A(4).结论:化合物1为新化合物,化合物3和4为首次从该植物中分离得到.%AIM:To study the chemical constituents of the roots ofIlex asprella Champ.ex Benth.METHODS:Compounds were isolated by silica gel,ODS,and Sephadex LH-20 column chromatography,and their structures were elucidated on the basis of physicochemical properties and spectroscopic analysis.RESULTS:Four triterpenoid glycosides were isolated and identified as (3β)-19-hydroxy-28-oxours-12-en-3-yl β-D-glucopyranosiduronic acid n-butyl ester (1),ilexasoside A (2),monepaloside F (3),and ilexoside A (4).CONCLUSION:Compound 1 is a new triterpenoid glycoside,and compounds 3 and 4 were isolated fiom this plant for the first time.
