摘要
Five minor compounds isolated from the leaves of Panax ginseng C. A. Meyer were characterized as 20（R）-protopanaxatriol （1）, daucosterin （2）, 3β, 12β-dihydroxy-dammar-20 （22）, 24-diene-3-O-β-D-glucopyranoside （3）, 20 （R）-protopanaxadiol-3-O-β-D-glucopyranoside （4） and ginsenoside-Rh2 （5）, respectively, on the basis of spectral analyses and chemical evidence. The two new saponins, 3 and 4, were named as ginsenoside-Rh3 and 20（R）-ginsenoside-Rh2.Nine other major saponins obtained simultaneously were identical with ginsenoside-Rh1（6）,-Rg3 （7）, -Rg2 （8）, -Rg1 （9）,-Re（10）,-Rd （11）, -Rc （12）, -Rb2（13） and Rb1 （14）, respectively.
