From the methanolic extract of the roots of Tribuluscistoides the cardioactive saponin-3, which is known to occur in the leaves, was isolated along with tribulosin, a pregnane-typeglycoside and eight new cholestane glycosides. D-(+)-Pinitol and sucrose were major constituents. The structures were established by spectroscopic studies of the isolated compounds, their acetylated derivatives and their
