| Abstract: | The aroma components in three cultivars of green tea,Wuniuzao,Jiukeng and Fuyun 6,were analyzed using headspace solid-phase micro-extraction-gas chromatography-mass spectrometry method(HS-SPME-GC-MS).We detected 43 kinds of aromatic substances in Wuniuzao,51 kinds in Jiukeng and 42 kinds in Fuyun 6.The results showed that main compounds in cultivars were alcohols,Wuniuzao had the highest content(57.6%) followed by Jiukeng(35.2%),while Fuyun 6 had the lowest content(22.5%),in which Wuniuzao had the highest linalool(38.94%).The contents of alkenes in Wuniuzao,Jiukeng and Fuyun 6 were 10.2%,20.0% and 23.3%;and for alkanes,10.1%,23.3% and 7.5% respectively.These 3 cultivars had low concentrations of aldehydes,ketones and esters;acids were not found in these samples.The major aromatic components in Wuniuzao were 1-octanol,linalool and its oxides,geraniol and α-farnesene.The major aromatic components in Jiukeng were linalool and its oxides,farnesol,dodecane,cyclocitral and 2,4-dimethyl-cyclohexanol,while Fuyun 6 had more 1-octanol,linalool and its oxides,nonanal,nerolidol and 3,4-epoxy-3-ethyl-2-butanone. |
