Two minor compounds isolated from the leaves of Panax ginseng C. A. Meyer were characterized as 20(R)-protopanaxadiol(I) and 3.beta.,6.alpha.,12.beta.-trihydroxydammar-20 (22),24-diene-6-O-.alpha.-L-rhamnosyl-(1 .fwdarw. 2)-.beta.-D-glucopyranoside (II) on the basis of spectral analysis and chemical evidences. I was isolated for the first time from the leaves; II was shown to be a new saponin and was named as ginsenoside-Rg4.
