Claim:
1. A quick extraction kit for use in extracting pesticide residues from a homogenized sample with a solvent and subsequently cleaning those extracted pesticide residues for analysis, comprising: a pipe having an output port located at the bottom of the pipe and an input port located at the top of the pipe for receiving a sample solution obtained by shaking a mixture of the homogenized sample and the solvent; a first powder mixture layer filled in the pipe, being capable of absorbing most of water of the sample solution and buffering a pH value of the sample solution, but not pesticide residues contained in the sample solution, when the sample solution flows through the first powder mixture layer; and a second powder mixture layer filled in the pipe and between the first powder mixture layer and the output port, and being capable of absorbing the rest of water of the sample solution and impurities interfering with the analysis, but not the pesticide residues, when the sample solution flows through the second powder mixture layer so as to export from the output port a cleaned extract containing the pesticide residues ready for the analysis.
