Fatty Acid Profile, Volatiles and Antibacterial Screening of Lipids of The Sponge Siphonodictyon coralliphagum Collected From The Bay of Bengal (Orissa Coast)

Abstract

The fatty acid composition as well as volatiles of total lipids in the marine sponge Siphonodictyon coralliphagum was analyzed. Most abundant are saturated fatty acid among which the % of docosanoic acid is found to be 15.49. Branched saturated fatty acids are also present in a good amount (23.45 %) and octadecanoic acid, 17 methyl-constitutes 11.62 % of it's total content. Monounsaturated fatty acids constitute only 5.53 % of the total fatty acid. Among poly unsaturated fatty acids, 5,9-hexacosadienoic acid is dominant (8.27 %). The lipid extract showed activity against Escherichia coli (A fish pathogen).
