摘要:
A total of thirteen steroidal saponins, including four new furostanol saponins, were isolated from the fresh stems of Dracaena concinna. The structures of new saponins were determined by detailed analysis of their H-1 and C-13 NMR spectra, hydrolysis, and by comparison of spectral data of known compounds. Two of the new furostanol saponins are unique in structure possessing a 4 alpha-hydroxyl group on the furostanol skeleton. (C) 1998 Elsevier Science Ltd. All rights reserved.
