摘要: 选取浙江云和县茶叶乌牛早50份,经乙腈提取, 旋转蒸发,用Cleanert TPT固相萃取柱净化,浓缩,内标法定量,采用GC-MS/MS测定13种农药残留。结果表明,50份样品中均未检出13种农药残留,说明该地山区气候优势,乌牛早农残检测率低,为该地茶叶产业发展提供一定的基础理论。

Abstract: To simultaneously determine 13 pesticides in 50 samples of local tea Wuniuzao. The samples extracted by acetonitrile and dried by rotated, purified by Cleanert TPT column,then subjected to GC-MS/MS using internal standard method. The treated samples pesticide residues were not detected. The results showed that the Wuniuzao of the local mountain area were very low. This paper provides some basic theory for the development of local tea industry.

Key words: GC-MS/MS, SPE, tea, Wuniuzao, pesticide residues
