Abstract

Many marine algae or seaweeds, are known to possess bioactive compounds whose structures are varied, ranging from terpenoids, sterols to some highly brominated phenolics. In a survey of indigenous seaweeds for biological activity, crude ethanolic extracts of Turbinaria, Sargassum, Chaetomorpha and Amphiroa were found to produce inhibition in growth of both gram-positive and -negative bacteria. Fractions from the crude extracts of Turbinaria conoides, Sargassum siliquosum and Sargassum baccularia responsible for the inhibition were identified.
