          Abstract: Polygonum lapathifolium L volatile oil in WengYi field was extracted by Steam Distillation method(SD), Microwave assisted extraction method(MAE) and Solid Phase micro Extraction(SPE), gas chromatography and mass spectrometry (GC-MS) was used to pare chemical ponent. The results show that the main ponents in volatile oil of Polygonum lapathifolium L include: Tetradecanal, Dodecanal, 1-Dodecanol, Caryophyllene, Decanal, 1-Decanol, 1,4,4a,5,6,7,8,8a-octahydro-2,5,5,8a-tetramethyl-1- Naphthalene, methanol, 8-bromo-Neoisolongifolene, Z,Z,Z-1,5,9,9-tetramethyl-1,4,7,-
          Cycloundecatriene, Undecanal, Epiglobulol, Thujopsene. The aroma pounds mainly include: Tetradecanal, Dodecanal, 1-Dodecanol, Caryophyllene, Decanal, 1-Decanol , Undecanal, (Z)-7,11-dimethyl-3-methylene-1,6,10-Dodecatriene. In the three different extraction methods, the volatile oil amount in ponents knds is the best o
