Formatted abstract
Investigation of Chamaelirium luteum roots led to the isolation of two new steroidal saponins, helosides A (R1,R2 = β-D-Glc) and B (R1 = β-D-Glc R2 = H), that contain a previously unreported aglycone, helogenin (R1,R2 = H). Their structures and absolute configuration were elucidated through MS-MS, NMR, chemical degradation, and X-ray crystallography.
