摘要
采用顶空-固相微萃取法提取清明及前后各1个月的鲜茶嫩叶中的香气物质,联合气质联用技术进行成分分析.结果显示,从节前、节中、节后样品中分别鉴定出53、55、59种成分,所鉴定成分峰面积分别占总挥发性化学成分的95.53%、97.51%、88.21%.
The aroma compounds in three samples , picked in different harvest seasons during Qingming festival , were extracted by the upper space-solid phase micro extraction （ HS-SPME） and analyzed by gas chromatogram-phy-mass spectrometry technology （ GC-MS ） .The results showed that 53、55、59 compounds were respectively identified from the three samples .The peak areas of mentioned compounds accounts for respective total volatile components was 95.53%,97.51%,88.21%.Based on this method, the aroma substances in tea can be quickly detected and change regulations were explored .
