- 論文の詳細を見る
From the roots of Clematis terniflora, nine new oleanolic acid 3,28-O-bisdesmosides called clematernosides A, B, E, F, G, H, I, J and K, and two new hederagenin 3,28-O-bisdesmosides called clematernosides C and D, have been isolated together with two known saponins, huzhangoside B and clematichinenoside C. The structures of the new saponins have been elucidated based on chemical and spectral evidence. Among the new saponins, clematernosides I and J have a nonsaccharide moiety and a total of twelve monosaccharide moieties in the molecule. This is the first report of the isolation and structure elucidatin of such "big" glycosides.
