- 22 Studies on the Constituents of Actinostemma lobatum MAXIM. (Cucurbitaceae) Structures of Triterpene Glycosides Isolated from the Herb
説明
Dammarane-type triterpene glycosides, named actinostemmoside A, B, C, D, G and H, baccharane-type triterpene glycosides, actinostemmoside E and F, and oleanane-type triterpene glycosides, lobatoside A, B, C, D, E, F, G and H were isolated from the herb of Actinostemma lobatum MAXIM. (Cucurbitaceae). Their structures were elucidated on the basis of the spectral and chemical evidences as shown in the text. The structure of actinostemmoside F was elucidated mainly on the basis of two dimensional-incredible natural abundance double quantum transfer experiment (2D-INADEQUATE) spectrum. Among dammarane-type actinostemmosides, D is the glycoside of the first naturally occurring dammarane having the (20R)-configuration, and actinostemmosides E and F are the second baccharane-type triterpene glycosides isolated from the natural source. Lobatoside B, C, D, E, F and G are cyclic bisdesmosides similar to tubeimoside I isolated from the tuber of Bolbostemma paniculatum (MAXIM.) FRANQUET. (Cucurbitaceae), and this is the second instance of the isolation of cyclic bisdesmoside from the plant kingdom.
