[Structure of chrysantellin B, a new saponin isolated from Chrysanthellum procumbens Rich (author's transl)].

A new saponin, chrysantellin B, has been found in a tropical plant Chrysanthellum procumbens Rich as a minor companion of chrysantellin A which was previously studied. The structure of chrysantellin B was determined by mass spectrometry, proton and 13C nuclear-magnetic resonance. The aglycone part is a triterpene: 3 beta, 16 alpha, 23-trihydroxy-olean-12-en-28-oic acid or caulophyllogenin.

Structure of a new saponin: chrysantellin A from Chrysanthellum procumbens Rich.

A new saponin has been isolated from a tropical plant Chrysantellum procumbens Rich. which is thought to be useful in the therapy of digestive troubles. The structure of this saponin was determined by chemical methods, nuclear magnetic resonance and mass spectrometry.
