초록

본 연구에서는 황소개구리(Rana catesbeiana Shaw)가 불포화지방산의 주요 공급원이 될 수 있다는 점에 착안하여, 국내에서 서식하고 있는 황소개구리에서 지방을 추출하여 지방산 조성을 분석하였다. 황소개구리의 다리와 몸통에는 1%(w/w)이하의 지방이 함유되어 있었으며, 계절에 따른 변화를 관찰할 수 없었다. 황소개구리 다리에서 분리한 지방에는 26~31%(w/w) 포화지방산, 16~24% 모노엔산, 30~40% 고도불포화지방산이 함유되어 있었으며, 몸통에서 분리한 지방에는 23~28% 포화지방산, 29~44% 모노엔산, 16~30% 고도불포화지방산이 함유되어 있었다. 황소개구리에서 추출한 지방의 주요 지방산은 palmitic acid, oleic acid, linoleic acid이었다. 다리에서 분리한 지방에는 3~8% eicosapentaenoic acid(EPA)와 6~10% docosahexaenoic acid(DHA)가 함유되어 있었으며, 몸통에서 분리한 지방에는 1~3% EPA 와 DHA가 각각 함유되어 있었다.

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.
