Methods : petroleum ether, ethyl acetate, ethanol Yujin combination of clove essential oil extraction. using capillary gas chromatography-mass spectrometry (GC\MS) - Computer joint qualitative and chromatographic area under a certain amount. Results : polar solvent extraction of essential oil is very different in chemical composition and relative content. 19 compounds were identified petroleum ether extract, and the main component is eugenol (Eugenol 68.54%); in ethyl acetate, extraction 48 compounds were identified, mainly composed of -Octadecenoic acid, (E)- 13.09% ， in alcohol extraction 14 compounds were identified, mainly composed of Phenol. 2-methoxy-3- (2-propenyl) - Conclusion : three different polarity of the solvent extraction of volatile oil in color, chemical composition, there are significant differences in the relative content. It provided the experimental and theoretical basis for the further study. Key words: Flos caryophylli; Wenyujin; compatibility; essen
