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.
