摘要：
Two new steroidal bisdesmosides, cambodracanosides A and B (1 and 2, resp.), were isolated from the fresh stems of Dracaena cambodiana, together with seven known glycosides. The structures of the new saponins were elucidated oil the basis of detailed spectroscopic analyses, including 1D- and 2D-NMR techniques, and acidic hydrolysis.
