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。

Abstract: 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.
