New triterpenoid saponins from fruit specimens of Panax japonicus collected in Toyama prefecture and Hokkaido (2).
Four new dammarane-type triterpenoid saponins, chikusetsusaponin FT(1) (1), chikusetsusaponin FT(2) (2), chikusetsusaponin FT(3) (3), chikusetsusaponin FT(4) (4), and six known triterpenoid saponins, chikusetsusaponin FK(4) (8), chikusetsusaponin FK(5) (9), chikusetsusaponin FK(2) (10), chikusetsusaponin FK(3) (11), chikusetsusaponin LN(4) (12), and chikusetsusaponin IVa (14), were isolated from the fruits of Panax japonicus C. A. MEYER, collected in Toyama prefecture, Japan, and five new dammarane-type triterpenoid saponins, chikusetsusaponin FT(1) (1), chikusetsusaponin FT(3) (3), chikusetsusaponin FT(4) (4), chikusetsusaponin FH(1) (5), chikusetsusaponin FH(2) (6), and eight known triterpenoid saponins, ginsenoside Re (7), chikusetsusaponin FK(5) (9), chikusetsusaponin FK(2) (10), chikusetsusaponin FK(3) (11), chikusetsusaponin LN(4) (12), 28-desglucosylchikusetsusaponin IVa (13), chikusetsusaponin IVa (14), and chikusetsusaponin V (15), were isolated from the fruits of P. japonicus C. A. MEYER, collected in Hokkaido, Japan. The structures of new chikusetsusaponins were elucidated on the basis of chemical and physicochemical evidences.
