摘　　要：报道了黄海海域成熟海蜇不同部位脂肪酸的研究结果。利用GCMS技术测定海蜇皮、海蜇头、海蜇生殖腺的脂肪酸组成。结果表明海蜇含有30多种脂肪酸,3个部位的脂肪酸组成差别不大;海蜇中含有丰富的多不饱和脂肪酸,含量在36.2%～38.7%之间,其中二十二碳六烯酸(DHA)、二十碳四烯酸(AA)和二十碳五烯酸(EPA)含量较高。The fatty acids composition in different parts of full-grown Rhopilema esculentum jellyfish from Yellow Sea was investigated. The lipids, extracted from the umbrella and oral arms and gonads of R. eculentum jellyfish, respectively were analysed by combined capillary gas chromatography/mass spectrometry. The results show that there are more than thirty kinds of fatty acids in jellyfish, and the fatty acid compositions of three parts of R. esculentum are almost the same. In the three parts, percentages of polyunsaturated fatty acids (PUFA) are high, and range from 36.23% to 38.74%. Docosahexaenoic acid (DHA), eicosatetraenoic acid (AA) and eicosapentaenoic acid (EPA) are three major PUFA.
