title: New steroidal glycosides from the fruits of Solanum anguivi.
abstract: Four new steroidal saponins, anguiviosides III (1), XI (2), XV (3), and XVI (4), were isolated and characterized from the fruits of Solanum anguivi. Their structures were elucidated on the basis of spectroscopic analysis. The occurrence of the cholestane glycosides 3 and 4 is considered from a biogenetic point of view.
