Abstract: To get a better understanding of aroma compounds derived from tea， extracts from Tieguanyin tea were obtained by the methods of water extraction， ethanol extraction， supercritical carbon dioxide extraction， and subcritical extraction， respectively， of which the volatile and semi\|volatile compounds， especially aroma compounds， were determined by the combination of gas chromatography and mass spectrum method （GC\|MS）. Additionally， performances of the various extracts on cigarette quality were investigated when the extracts were applied in cigarette filters as well. As the results indicated， compared with the other three methods， supercritical carbon dioxide extraction showed a better contribution to aroma compounds extraction from Tieguanyin tea in this research. According to the assessment of cigarette quality taste， extracts from supercritical carbon dioxide extraction method also had a better significant influence on it. It is concluded that supercritical carbon dioxide extraction is a relatively appropriate method， with high efficiency and economic effectiveness， for preparing cigarette quality-oriented extract．
