Abstract
Peculiar novel steroidal saponins with E-ring opened skeleton, a cholesten- 3 beta ,16.22,26-tetraol 3,26-di-O-glycoside corresponding to the precursor of the spirostanol and furostanol. a 16,22-dicarbonyl type steroid and a 2 0-22 seco-type steroid have been obtained from some Solanum genera plants. The occurrence of their unusual compounds would propose new important bioge netic routes for steroidal glycosides. (C) 2001 Elsevier Science Ltd. All r ights reserved.
