| Abstract: | The volatile components in Allium cepa Linn 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 nomalization.There were thirty-one compounds identified from Allium cepa Linn,representing 86.48% of the total oil.Main constituents of the extract from the Allium cepa Linn were found to be aldehydes,acids,sterols,alkanes and heterocyclic compounds.Among them the contents of aldehydes,acids and alkanes were relatively high. |
