Abstract:Volatile components were extracted from fresh Phyllanthus urinaria L. by sonication with anhydrous ether,and analyzed by gas chromatography-mass spectrometry(GC-MS) with headspace solid phase micro-extraction(HS-SPME).Seventy-six components were identified with the identification rate 96.5%.the content of oxygenated compounds is more than 96.0% in the volatile composition.The main components included 2-hexenal(19.75%),3-Hexen-1-ol,(Z)-(13.89%),phenylethyl alcohol(9.76%),2-hexen-1-ol,(E)-(8.03%),1-hexanol(7.94%),(E)-2-hexenoic acid(5.11%),hexanoic acid(3.51%),3-hexenoic acid,(E)-(3.32%),methyl salicylate(3.29%) and etc.
Keywords:Phyllanthus urinaria L    volatile components  HS-SPME  GC-MS
