• Six new minor saponins, together with known ginsenosides, were isolated from the leaves of Panax ginseng. The new saponins were named as ginsenoside-Rh_5, -Rh_6, -Rh_7, -Rh_8, -Rh_9, and -Rg_7, and their structures were elucidated on the basis of chemical and physicochemical evidence to be as follows : ginsenoside-Rh_5 : 3β, 6α, 12β, 24ζ-tetrahydroxy-dammar-20(22), 25-diene 6-O-β-_D-glucopyranoside(1), -Rh_6 : 3β, 6α, 12β, 20(S)-tetrahydroxy-25-hydroperoxy-dammar-23-ene 20-O-β-_D-glucopyranoside(2), -Rh_7 : 3β, 7β, 12β, 20(S)-tetrahydroxy-dammar-5, 24-diene 20-O-β-_D-glucopyranoside(3), -Rh_8 : 3β, 6α, 20(S)-trihydroxy-dammar-24-ene 20-O-β-_D-glucopyranoside(4), -Rh_9 : 3β, 6α, 20(S)-trihydroxy-12β, 23-epoxy-dammar-24-ene 20-O-β-_D-glucopyranoside(5)and -Rg_7 : 3-O-β-_D-glucopyranosyl 3β, 12β, 20(S), 24(R)-tetrahydroxy-dammar-25-ene 20-O-β-_D-glucopyranoside(6).
