Analysis of fatty acids from Codium iyengarii (Bryopsidophyceae).

The green seaweed Codium iyengarii Bphirg., collected from the coast of Karachi, has been studied for its fatty acid composition. The acids were converted into methyl caters and identified by GC-MS, which revealed the presence of 11 saturated, 10 monoethenoic and 2 ethinoic acids. Palmitic acid was present in the highest amount, while dodecenoic acid was in largest quantity among unsaturated fatty acids. Malonic, heptanoic, tridecynoic, hexadecynoic, tricosenoic, and heptacosanoic acids arc being reported for the first time front any species of Codium as well as any seaweed of Pakistan.
