The FA composition of the pelagic jellyfish Aurelia sp. collected from off-shore Western Australia waters was determined by capillary GC and GC-MS, with confirmation of PUFA structure performed by analysis of 4,4-dimethyloxazoline derivatives. PUFA constituted 47.6% of the total FA, with the essential PUFA eicosapentaenoic acid (EPA), arachidonic acid, and DHA accounting for 34%. Of particular interest, the unusual very long chain PUFA 6,9,12,15,18,21-tetracosahexaenoic acid (THA, 24:6n-3) was present at 9.3%, and the rarely reported 6,9,12,15,18-tetracosapentaenoic acid (24:5n-6) also was detected at 0.8%. To our knowledge, this represents the first report of THA as a major PUFA in a pelagic marine organism.
通过毛细管气相色谱法（GC）和气相色谱 - 质谱联用仪（GC-MS）测定了从西澳大利亚近海水域采集的浮游水母海月水母（Aurelia sp.）的脂肪酸（FA）组成，并通过分析4,4 - 二甲基恶唑啉衍生物对多不饱和脂肪酸（PUFA）结构进行了确认。PUFA占总FA的47.6%，必需的PUFA二十碳五烯酸（EPA）、花生四烯酸和二十二碳六烯酸（DHA）占34%。特别值得关注的是，异常的超长链PUFA 6,9,12,15,18,21 - 二十四碳六烯酸（THA，24:6n - 3）含量为9.3%，且罕见报道的6,9,12,15,18 - 二十四碳五烯酸（24:5n - 6）也被检测到，含量为0.8%。据我们所知，这是THA作为浮游海洋生物中主要PUFA的首次报道。
