  摘要：

  On the basis of chemical and physicochemical evidence, the structures of four dammarane triterpene glycosides, named Kizuta saponins K7A (I), K7B (VII), K9 (X) and K13 (XII), which were isolated from the stem and bark of Hedera rhombea BEAN (Araliaceae), were established as follows : I, 3-oxo-20 (S)-dammar-24-ene-6α, 20, 21, 26-tetraol 26-O-β-D-glucopyranoside ; VII, 20 (S)-dammar-24-ene-3β, 6α, 20, 21, 26-pentaol 26-O-β-D-glucopyranoside ; X, 20 (S)-dammar-24-ene-3β, 6α, 20, 26-tetraol 3, 26-di-O-β-D-glucopyranoside ; XII, 20 (S)-dammar-24-ene-3β, 6α, 20, 26-tetraol 3-O-β-sophoroside-26-O-β-D-glucopyranoside.
