Abstract
Three new pregnane glycosides designated as pergulinine, pallicine and pallicinine have been isolated from the chloroform soluble extract of Pergularia pallida. On the basis of chemical and spectroscopic evidence their structures were established as drevogenin P-3-O-α-L-rhamnopyranosyl-(1→4)-O-β-D-cymaropyranoside, cissogenin-3-O-β-D-oleandropyranoside and calogenin-3-O-α-L-diginopyranosyl-(1→4)-O-β-D-digitoxopyranoside, respectively.
