The quantitative analysis method of determination of anthraquinone in tea by GPC cleaned up with GC-MS-MS quantitative analysis method.Between the detected concentration range (10~500μg/L) with good correlation coefficient ( r=0.9997) , showed good linearity.Injecting the solution of spiked 50 μg/kg six times, the relative standard deviation was 2.68%.The limit of detection and limit of quantization were 3 μg/kg and 10 μg/kg.At the spiked level of 10 , 50 and 200 μg/kg, the recoveries were 80.2%~114.7%, and the relative standard deviation were 4.51%~9.12%.This method was simple, rapid, selective and accurate, meet the requirement of pesticide analysis in tea.It could detect anthraquinone in tea.
