Abstract
The objective of this study was to analyze fatty acid composition in lipids extracted from bullfrogs (Rana catesbeiana Shaw) inhabiting in Korea. Lipid contents in bullfrog legs and bodies were less than 1% (w/w, wet basis) and seasonal variation of the lipid contents was not observed. Lipids in bullfrog legs consisted of 26~31% (w/w) saturated fatty acids, 16~24% monounsaturated fatty acids, and 30~40% polyunsaturated fatty acids. Lipids in bullfrog bodies consisted of 23~28% saturated fatty acids, 29~44% monounsaturated fatty acids, and 16~30% polyunsaturated fatty acids. The major fatty acids in lipids extracted from bullfrogs were palmitic acid, oleic acid, and linoleic acid. Lipids in leg muscles contained 3~8% eicosapentaenoic acid (EPA) and 6~10% docosahexaenoic acid (DHA). Lipids in bodies had 1~3% EPA and 1~3% DHA.
