摘要
为了寻找长白楤木嫩芽中的皂苷活性单体,采用70%乙醇提取,AB-8大孔吸附树脂纯化,硅胶柱层析、凝胶柱层析和制备液相进行分离,利用NMR波谱法鉴定化合物的结构。结果分离得到一个皂苷单体,经鉴定为刺龙芽皂苷C。
A saponin monomer was obtained from the young sprouts of Aralia continentalis through extraction with 70% aqueous ethanol solution,sequential purification by AB-8 macroporous resin adsorption,silica gel column chromatography and Sephadex LH-20 column chromatography and preparative HPLC separation.The compound was structurally identified by NMR spectroscopy as congmuyanoside C.
