Volatile flavor components from various edible portions of Commelina communis L. were collected by simultaneous steam distillation-extraction(SDE) method using diethyl ether as solvent. Essential oils were analyzed by gas chromatography(GC) and combined gas chromatography-mass spectrometry(GC-MS). Eighty nine volatile flavor components, including 33 hydrocarbons, 4 aldehydes, 9 ketones, 23 alcohols, 6 esters, 10 acids and 4 miscellaneous ones were confirmed in whole samples. Twenty three components, including 14 hydrocarbons, 7 alcohols and 2 esters were confirmed in leaves. Six components, including 3 hydrocarbons and 3 alcohols were confirmed in stems, and 18 components, including 13 hydrocarbons, 1 ketone, 3 alcohols and 1 acid were confirmed in roots. The kinds and amounts of volatile flavor components revealed different patterns depending upon various edible portions. Relatively greater numbers of volatile flavor components were identified in leaves compared with other portions of this wild plant.
