摘要: 制备三列凹顶藻和松节藻醇提物,采用气相色谱-质谱联用仪(GC/MS)对这两种海藻提取物脂肪酸进行了分析,各分离出17个和18个峰,鉴定了12种脂肪酸。用峰面积归一化法得出各类脂肪酸的相对百分含量。凹顶藻提取物中含饱和脂肪酸4种,总体百分含量为18.095%;单不饱和脂肪酸2种,总百分含量为3.910%;多不饱和脂肪酸种类较多,共有6种,总百分含量为7.437%。松节藻醇提物中4种饱和脂肪酸的含量为51.842%,2种单不饱和脂肪酸含量为13.124%,6种多不饱和脂肪酸含量为27.375%。

Abstract: To extract the fatty acids compounds from Laurencia tristicha and Rhodomela confervoides, the fatty acid contents of the two kinds of seaweeds were separated and identified by gas chromatography mass spectrometry (GCMS) method. 17 and 18 peaks were separated respectively and 12 kinds of fatty acids were identified. The contents of the fatty acids were determined by using the normalization method. Laurencia ethanolic extraction contained 4 kinds of satutated fatty acids, 2 kinds of monounsaturated fatty acids and 6 kinds of polyunsaturated fatty acids with the contents as 18.095%, 3.910% and 7.437%,respectively. Rhodomela ethanolic extraction contained the same types of fatty acids with the contents as 51.842%, 13.124% and 27.375%, respectively.
