Abstract
New polyhydroxylated steroidal saponins (1, 2)were isolated from the t ubers of Brodiaea californica. The structures were determined by spect roscopic analysis and acid-catalyzed hydrolysis. The bisdesmosidic sap onin (2) is unique in structure, and is the first representative of a steroidal saponin bearing 6-deoxy-D-gulopyranose among both the steroi dal and triterpene saponins reported up to the present.
