Abstract
Three novel steroidal glycosides, attenuatoside B-I (I), B-II (II), and C (III), were isolated from H. attenuata. Their structures were established by comparison of their 1H- and 13C-NMR spectra with that of the previously identified attenuatoside A-I, from which the different in no. and configuration of OH groups on the sterol moiety and in the nature of the sugar moiety.File in questo prodotto:
