黑蚂蚁的脂肪酸及抗氧化性能的分析

对黑蚂蚁中脂肪酸的组成和含量进行测定。采用索氏提取法提取其脂肪酸,再进行甲酯化处理,以气相色谱-质谱联用仪进行了分离和鉴定。由黑蚂蚁中分离鉴定出11种脂肪酸,占脂肪酸总量的99.78%,不饱和脂肪酸占脂肪酸总量的80.65%,饱和脂肪酸占脂肪酸总量的19.13。通过流动注射化学发光法分析了黑蚂蚁的抗氧化性能,结果表明,黑蚂蚁具有较强的抗氧化性能。

Analysis of fatty acids and antioxidative effect for black ants

To determine the fatty acids in black ants,the black ants were extracted by soxhlet extraction.The fatty acids in the oil were esterified by sodium hydroxide-methanol,and then analyzed by gas chromatography-mass spectrometry(GC/MS).11 fatty acids were identified in the black ants the contents of the identified fatty acids make up 99.78%,the unsaturated fatty acids were 80.65% and saturated fatty acids were 19.13%.The main components are unsaturated fatty acids in the black ants.Antioxidation effect of the black ants was analyzed by flow-injection chemiluminescence.The results show that the black ants have a strong antioxidative effect.
