title: A new steroidal saponin from dragon's blood of Dracaena cambodiana.
abstract: Phytochemical study on dragon's blood of Dracaena cambodiana led to a new steroidal saponin, cambodianoside G(1), and six known ones (2-7). The structure of the new compound was elucidated on the basis of detailed spectroscopic analysis.
