수산물의 지질에 관한 연구 ( 제2보 ) - 해조류 지질의 지방산조성에 대하여 -

The patterns of fatty acid composition of lipid extracted from eight species of edible marine benthic algae; i.e. two species of green, five of brown and one of red algae, were investigated quantitatively by using gas liquid chromatography. The total lipid contents in average of the algae were 1.51% in the green algae, 2.81% in brown algae and 1.02% in red algae respectively. Upon analyzing fatty acid composition, green algae contained the highest proportion of C_16:0 acid and comparatively higher content of C_18:1, C_18:2 and C_18:3 acids than the other algae. In brown algae, C_16:0 acid content was highest, but not more than that of green algae, and C_14:0, C_18:1 acids were higher than other C_16:1, C_18:2, and C_18:3 acids while the content of C_18:0 acid was very low. Red algae showed low content of C_14:0, C_18:1 and C_18:3 acids, but the content of C_16:0 acid was high as a major component. In regard to the composing patterns of carbon number of fatty acid of algae; i.e. C_14, C_15, C_16, C_18 and C_22 acids, the green algae contained C_16 and C_18 acids, the brown algae C_16, C_18 and C_22 acids, and the red algae C_15 C_16, and C_18 acids as the major component.
