Abstract:

A new malonylated dammarane-type triterpene oligoglycoside, named malonyl-notoginsenoside-R4(1), was isolated from the fresh root of Panax ginseng C. A. Mey. The structure of malonyl-notoginsenoside-R4 was determined as 3-O-[6-O-malonyl-β-D-glucopyranosyl(1→2)-β-D-glucopyranosyl]-20-O-[β-D-xylopyranosyl(1→6)-β-D-glucopyranosyl(1→6)-β-D-glucopyranosyl]-20(S) protopanaxadiol on the basis of physicochemical properties and spectral analysis.

Key words: Panax ginseng, Fresh ginseng radix, Triterpenoid, Malonyl-notoginsenoside-R4
