Five new steroidal glycosides from the stems of Solanum sodomaeum.

Besides 12 known glycosides, five new steroidal glycosides have been isolated from the stems of Solanum sodomaeum L. (Solanaceae). The chemical structures of these five glycosides were determined on the basis of spectroscopic data as well as chemical evidence, and the structure of one known steroidal glycoside was corrected.
