A new saponin, malonylginsenoside Ra3, was isolated from the fresh root of Panax ginseng, along with four known ginsenosides. The new compound was identified as (20S)-protopanaxadiol-3-O-(6-O-malonyl-beta-D-glucopyranosyl(1-->2)-beta-D-glucopyranoside-20-O-beta-D-xylopyranosyl(1-->3)-beta-D-glucopyranosyl(1-->6)-beta-D-glucopyranoside on the basis of extensive 1D and 2D NMR as well as HRESI-MS spectroscopic data analysis.
一种新的甾体皂苷，丙二酰基 Ginsenoside Ra3，从新鲜的人参根中分离出来，与四个已知的人参皂苷一起。新化合物被鉴定为（20S）-原人参二醇-3-O-（6-O-丙二酰基-β-D-吡喃葡萄糖基（1-->2）-β-D-吡喃葡萄糖苷-20-O-β-D-吡喃木糖基（1-->3）-β-D-吡喃葡萄糖苷-（1-->6）-β-D-吡喃葡萄糖苷，基于广泛的 1D 和 2D NMR 以及 HRESI-MS 光谱数据分析。
