Steroidal glycosides from Agave utahensis.
Three new spirostanol glycosides (1-3) and a new furostanol glycoside (4), together with two known spirostanol glycosides (5 and 6) were isolated from the whole plants of Agave utahensis (Agavaceae). The structures of the new compounds were determined by spectroscopic analysis and the results of hydrolytic cleavage.
