| 中文摘要: |
| 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3508％；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-3 PUFA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%。 |
| 英文摘要: |
| 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%. |
