Abstract

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 on the basis of detailed spectroscopic analyses, including 1D‐ and 2D‐NMR techniques, and acidic hydrolysis.
