Determination of Volatile Chemical Components of Polygonum odentale L.by GC-MS

Wild growing plant Polygonum odentale L.volatile was extracted by water-steam distillation,gas chromatography-mass spectrometry(GC-MS) was used to determine its chemical component,and normalization was employed to determine its relative content.Results:18 peaks and 13 compounds given by GC-MS have been identified,and anethole was the main components,which accounts for 83.66% of the total volatile.Other components account for 17.34% of the total volatile.
