A novel dammarane-type triterpene oligoglycoside, named ginsenoside-Rg₆, 3, was isolated from the stem-leaves of Panax ginseng C. A. Mey., together with two known ones. 20(S)-ginsenoside-Rg₂ 1 and 20(R)-ginsenoside-Rg₂ 2. On the basis of chemical and physicochemical evidence. the structure of ginsenoside-Rg₆ have been elucidated as 6-O-α-L-rhamnosyl-(1→2)-β-D-glucopyranosyl-dammarane-(E)-20(22), 24-diene-3β. 6α, 12β-triol.
