楤木根皮中皂甙化学成分的研究

STUDIES ON THE SAPONINS FROM THE ROOT BARK OF ARALIA CHINENSIS L.

摘要: 楤木根皮中的主要成分是皂甙。将总皂甙以柱层析分离,得到三个化合物(Ⅰ～Ⅲ),经光谱分析和化学方法证明,Ⅰ为楤木皂甙A(araloside A);Ⅱ为银莲花甙(narcissiflorine);Ⅲ是3-O-β-D-吡喃葡萄糖-(1→2)-β-D-吡喃木糖-(1→)2)-α-L-阿拉伯糖-齐墩果酸。Ⅲ为一新皂甙,命名为楤木皂甙D(araloside D)。

Abstract: Six saponins were isolated from the root bark of Aralia chinensis L.. The three saponins Ⅰ, Ⅱ and Ⅲ were identified as araloside A (Ⅰ), narcissiflorine (Ⅱ) and oleanolic acid 3-O-β-D-glucopyranosyl-(1-2)-β-D-xylopyranosyl-(1-2)-α-L-arabinopyranoside (Ⅲ). Saponin Ⅲ was found to be a new compound and was named as araloside D.
