Abstract
The present thesis is divided into two chapters. Chapter 1 relates to chemical investigation of the medicinal plant Andrachne aspera. This study has resulted in the isolation of three novel piperidine alkaloids from this plant which have been named as andrachcine, andrachamine and AA-3. The structures fro andrachcine and andrachamine have been proposed on the basis of spectroscopic analysis.

The second chapter deals with isolation of steroidal glycoside named as attenuatoside A-1,halityloside D and E. These glycosides are isolated for the first time from starfish porania pulvillus.

The structures for these isolated saponins have been proposed on the basis of spectroscopic and chemical studies.
