title: Comparative composition of fatty acids of codium decortica tum and C. Flabellatum (bryopsidophyceae).
abstract: Fatty acid composition of two green seaweeds Codium decorticatum f. monstrosum (Montagne) Nizamuddin and C. flabellatum Silva et Nizamuddin, found in Karachi coastal waters, has been reported. Altogether 15 saturated and 22 unsaturated fatty acids including 13 monoenoic, 4 dienoic and 5 trienoic acids were identified as methyl esters by gas chromatography-mass spectrometry. They include one saturated hydroxy and three substituted unsaturated fatty acids. The 2,3-dimethoxy propanoic, 3,8.dimethyl-2,7-nonadienoic, 7-ethyl-3-methyl-2, 6.undecadienoic, 3,7,11-trimethyl-2, 6, 10-dodecatrienoic, nonacosatrienoic and nonacosanoic acids are being reported for the first time from any species of Codium as well as any seaweed of Pakistan. Both the seaweeds exhibited specific differences in their fatty acid composition.
