Effect of sample temperature and adsorption time on the SPME(solid phase microextraction) treatment of seeds of Polygonum orientale L. were investigated. The optimal extraction conditions were absorption at 60℃ for 60 min and desorption at 250℃ for 5 min. Samples of seeds of P. orientale L. were analyzed by GC-MS coupled with SPME. Through comparison with mass spectra database，forty-tree components were identified，covering 76.73% of the total peak areas in the GC-MS total ion current chromatography. The characteristic components were Thujopsene(6.99%),Caryophyllene5.59%),2,5,5,8a-Tetramethyl-6,7,8,8a-tetrahydro-5H-naphthalen-1-one(5.52%),α-Caryophyllene(4.29%),1,2,4a,5,6,8a-hexahydro-4,7-dimethyl-1-(1-methylethyl)-Naphthalene(4.04%),Caryophylleneoxide(3.60%),α-Cyperone(3.54%),4,5,5a,6,6a,6b-hexahydro-4,4,6b-trimethyl-2-(1methylethenyl)-2H-Cyclopropa-benzofura n(3.54%),Geranylacetone(3.48%).
