Isolation and structure elucidation of natural products from marine organisms and determination of their biological activity.

Abstract

Marine organisms are a fascinating source of biologically active secondary metabolites such as anti-bacterial, anti- fungal, insecticidal, cytotoxic and anti-cancer agents. This research projesct was aimed at indentifying such bio-active compunds from Sri Lankan marine organisms. The extracts of a number of organisms collected from the Sri Lankan coastal waters were screened for anti- bacterial (against staphylococcus aureus, E. coli, and Pseudomonas sp.) and anti -fungal ...
