| Abstract: | The volatile chemical components in Onion were studied and extraction were determined by GC-MS analysis.Method: The volatile components were obtained by microwave assisted extraction.The chemical components were separated and identified by gas chromatography-mass spectrometer(GC-MS).The relative content of each component was determined by area normalization.Result: Twenty-eight peaks were identified from Onion,representing 81.3 % of the total oil.Conclusion: Main constituents of the extract from the Onion were found to be Acids,sterols,alkanes,aldehydes and heterocyclic compounds. |
