Abstract

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.
