Isolation and characterisation of some antifouling agents from the brown alga <i>Sargassum</i> <i>confusum</i>

Abstract

Fats and phthalic acid derivatives were isolated and characterised based on their spectral analysis from the antifouling activity guided fractions of n-hexane and methanol extract of the brown alga Sargassum confusum. The fractions, as well as the isolated compounds, demonstrated significant antifouling activity against spores of a major fouling alga Ulva pertusa with 50-75% decrease of spore attachment on agar-coated slides.
