摘要
目的:对番荔枝籽中的油脂进行提取和脂肪酸组成分析。方法:采用索氏提取法对番荔枝籽中的油脂进行提取,甲酯化后运用气相色谱-质谱联用技术进行分析和鉴定。结果:番荔枝籽油得率为(24.17±1.08)%,番荔枝籽油脂中含有16种脂肪酸,主要的脂肪酸为油酸(42.91%)、亚油酸(38.53%)、2,6,10,14-四甲基十五烷酸(15.43%)、十八碳三烯酸(1.33%)、花生油酸(1.27%)和十七烷酸(0.52%)等,其中不饱和脂肪酸含量高达82.77%以上。结论:番荔枝油脂富含不饱和脂肪酸,具有较高的营养价值和保健功能。
Objective： The fatty acids were extracted from Annona seeds and analyzed by gas chromatography-mass spectrometry（GC-MS）.Methods： Annona seeds oil was extracted from by Soxhlet and the methyl ester product was analyzed by GC-MS technology.Results： the yield of Annona seeds oil was（24.17±1.08）%.The Annona seeds oil contains 16 types of fatty acids and the main fatty acids include oleic acid（42.91%）,linoleic acid（38.53%）,2,6,10,14-tetramethyl pentadecanoic acid（15.43%）,octadecadienoic acid（1.33%）,arachidonic acid（1.27%） and heptadecanoic acid（0.52%）.Unsaturated fatty acid content was up to 82.77%.Peroxide value of 1.32 was lower than that of the edible vegetable oil provided by food safety standards.Conclusion： High nutritional value of Annona seeds oil can be ascribed to rich content of unsaturated fatty acids and low peroxide value.
