Investigation of Chamaelirium luteum roots led to the isolation of two new steroidal saponins, helosides A and B, that contain a previously unreported aglycone, helogenin. Their structures and absolute configuration were elucidated through MS-MS, NMR, chemical degradation, and X-ray crystallography.
