Abstract :
Peculiar novel steroidal saponins with E-ring opened skeleton, a cholesten-3β,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 20–22 seco-type steroid have been obtained from some Solanum genera plants. The occurrence of their unusual compounds would propose new important biogenetic routes for steroidal glycosides.
