| 摘 要： | <正> 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-Rh_2 (5), respectively, on the basis of spectral analyses and chemical evidence. The two new saponins, 3 and 4, were named as ginsenoside-Rh_3 and 20(R)-ginsenoside-Rh_2.Nine other major saponins obtained simultaneously were identical with ginsenoside-Rh_1(6),-Rg_3 (7), -Rg_2 (8), -Rg_1 (9),-Re(10),-Rd (11), -Rc (12), -Rb_2(13) and Rb_1 (14), respectively.
