用氨基酸自动分析仪和气相色谱-质谱联用(GC-MS)技术分析浒苔的氨基酸、脂肪酸组成和含量。结果表明,浒苔中含有18种氨基酸,氨基酸总量(TAA)为8.78%,人体所需的必需氨基酸(EAA)占总氨基酸的35.08%;从浒苔中鉴定出19种脂肪酸,由C12~C24脂肪酸组成,其中不饱和脂肪酸占脂肪酸总量的65.78%,以多不饱和脂肪酸为主,特别是16碳和18碳脂肪酸比较丰富,ω-3PUFA占脂肪酸总量的29.68%,绿藻的特征脂肪酸——亚麻酸(C18∶3n3)相对含量达18.70%。
The compositions and contents of amino acids and fatty acids of Enteromorpha prolifera were determined by automatic amino acid analyzer and gas chromatograph-mass spectrometry (GC-MS). Eighteen amino acids were found in the samples and total amino acids (TAA) was 8.78%. Human essential amino acids (TAA) covered 35.08% of the total amino acid. Among the 19 kinds of fatty acids of C12-C24, the content of total unsaturated fatty acid was 65.78%, which were mainly high polyunsaturated fatty acid with a high percentage of C12 and C24. The content of ω-3 unsaturated fatty acid was 29.68% of all fatty acids, and the content of characteristic fatty acid of chloraphyta--all cis-6,9,12-Octadecatrienoic was 18.70%.
