Six new steroidal saponins, cambodianosides A-F (1-6), together with seven known ones, were isolated from the dragons blood of Dracaena cambodiana.The structures of 1-6 were elucidated on the basis of detailed spectroscopic analysis, including 1D and 2D NMR techniques and chemical methods.The cytotoxicities of all the isolated compounds were evaluated in vitro against three human cancer cell lines, and compounds 7, 8, and 11 showed significant inhibitory activities.
