| Abstract: | Seasonal
variation on fatty acid composition of 51 algal species from Gulf of Mannar
Marine Biosphere Reserve has been studied . Analysis of fatty acids by gas
chromatography revealed the presence of higher amount of saturated fatty acids
than unsaturated fatty acids. Among the saturated fatty acids, the amount of
palmitic acid was higher (96.88%) in all the seasons and species studied. In
the present investigation, the highest relative percentage of lauric acid
(31.58%), tridecanic acid (4.46%), nonadecanoic acid (2.06%), heneicosanoic
acid (23.9%), oleic acid (21.38%) and linolenic acid (10.42%) were recorded
during spring season from Ulva lactuca,
Acanthophora spicifera, Valoniopsis pachynema, Turbinaria decurrens,
Stoechospermum marginatum and Cheilosporum
spectabile respectively. Highest percentage of heptadecanoic acid (12.36%)
and behenic acid (8.92%) were recorded during monsoon season from Caulerpa taxifolia and Terbinaria ornate. Myristic acid
(24.71%), pentadecanoic acid (3.29%), palmitic acid (96.88%), stearic acid
(6.99%) and linoleic acid (28.61%) were high in Halimeda tuna, Valoniopsis pachynema, Ulva fasciata, Bryopsis plumose and
Ulva reticulata respectively during
post monsoon season. Padina
tetrastromatica showed the highest relative percentage of arachidic acid
(12.6%) during summer.
