中文摘要：

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。

英文摘要：

AIM： To study the chemical constituents of the roots ofllex 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 phys- icochemical properties and spectroscopic analysis. RESULTS： Four triterpenoid glycosides were isolated and identified as （3β）-19-hydroxy-28-oxours-12-en-3-yl fl-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 from this plant for the first time.
