Extraction and GC-MS Analysis of Fatty Acids from Annona squamosa L. Seeds

Abstract

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.

Key words: annona seeds, fatty acid, gas chromatograph-mass spectrometer (GC-MS)
