Abstract: | Chikusetsusaponin II and IVc, the minorsaponins of Panacis japonici rhizoma (rhizome of Panax japonicum C.A. MEYER) have been isolated. The structure of these saponins were established as being oleanolic acid-(3)-β-D-glucopyranosyl (1→6)]-β-D-glucuronopyranoside and 20S-protopanaxatriol-6-(O-α-L-rhamnopyranosyl (1→2)-β-D-glucopyranoside]-20-O-β-D-glucopyranoside. Chikusetsusaponin II is a new structure, while chikusetsusaponin IVc is identical with ginsenoside-Re, isolated from P. ginseng C. A. MEYER. |
