Abstract
The fatty acid composition of three Holothuria spp. and one Bohadschia sp. were
determined by gas liquid chromatography. Arachidonic acid (20:4n-5) was the predominant
fatty acid (25.29-34.49%) in the three Holothuria spp. while eicosatrienoic (20:3n-6) was
predominant in the Bohadschia sp. Docosahexaenoic acid (22:6n-3) and eicosapentaenoic acid
(20:5n-3) concentrations were appreciable. The mineral (Na, K, Ca, Mg, Fe, Zn, Cu, Cd, Pb,
Hg, As, Se) composition of the echinoderms were determined by Atomic Absorption
Spectrophotometry. The alkali (Na and K) and alkaline (Ca andMg)metalswere abundant in the
tissuewhile the heavymetals (Cu, Cd, Pb, Hg) and metalloids (As and Se)wereminor constituents.
