Abstract

The work described in the present thesis is mainly concerned with the isolation and structure elucidation of saponin constituents of Zytgophyllum propinquum (Syn. Z coccineum L.) belonging to the family Zygophylla-ceae. As a result of these investigations five new triterpeniodal saponins have been isolated which were named as zygophyloside A, Zygphyloside B, Zygophloside C, Zygophykloside D and Zygophyloside E, Together with these compound another triterpenoidal saponin, one steroidal saponin and a triterpene ester were also isolated and reported for the first time from this plant. Zyugophyloside D and zygophyloside E were isolated from the column chromatography of the butanolic extract of Zygophyllum propinquum, while the rest of other compounds were isolated from the ethyl acedtate extract of this plant
