A. M EYER , collected in Kumamoto prefecture, Japan, and two new dammarane-type triterpenoid saponin, chikusetsusaponin FK5 ( 5 ) and chikusetsusaponin FM1 ( 8 ), and five known triterpenoid saponins, ginsenoside Rb3 ( 9 ), ginsenoside Rc ( 10 ), ginsenoside Re ( 12 ), ginsenoside Rg1 ( 13 ), and floralquinquenoside E ( 16 ), were isolated from the fruits of P. japonicus C. A. M EYER , collected in Miyazaki prefecture, Japan. The structures of new chikusetsusaponins were elucidated on the basis of chemical and physicochemical evidences.
