Abstract

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-β-D-glucopyranosyl(1→2)-β-D-glucopyranoside-20-O-β-D-xylopyranosyl(1→3)-β-D-glucopyranosyl(1→6)-β-D-glucopyranoside on the basis of extensive 1D and 2D NMR as well as HRESI-MS spectroscopic data analysis.
Keywords: Panax ginseng; ginsenoside; malonyl-ginsenoside Ra3 Panax ginseng; ginsenoside; malonyl-ginsenoside Ra3
