secretions revealed triacylglycerols as major glandular constituents. Twelve major medium-chain fatty acids were found to be conjugated to glycerol in different combinations, resulting in complex mixtures. These acids were identified by transesterification and subsequent derivatization of natural samples, and their structures were verified by synthesis. The natural glycerides contain predominantly three of
研究了at(Sphenodon punctatus)的泄殖腔分泌物的亲脂性含量。分泌物的CH2Cl2提取物的GC / EI-MS分析表明,三酰基甘油是腺体的主要成分。发现十二种主要的中链脂肪酸以不同的组合与甘油结合,形成复杂的混合物。这些酸通过酯交换反应和随后的天然样品衍生化来鉴定,其结构通过合成验证。天然甘油酯主要包含以下三种酸:辛酸(A),(E)-和(Z)-辛-4-烯酸(B和C,分别),(4E,6Z)-辛基-4,6 -二烯二酸(丁二酸; D),(R)-2,6-二甲基庚酸(E),(R)-2,6-二甲基庚-5-烯酸(F),(Z)-dec-4-烯酸(G ),(4Z,7Z)-癸-4,7-二烯酸(H),(R)-3,7-二甲基辛-6-烯酸(I),(R)-4,8-二甲基非-7-烯酸(J),(2R,6S)-2,6,10-三甲基十一烷基-9-烯酸(K)和(2R,5E)-2,6,10-三甲基十一烯-5,9
