| Abstract: | The residual malachite green （MG）in fishery products was reduced to leuco-malachite green （LMG）with KBH4, samples were extracted by LMG＇s pre-treatment kit,and purified by solid-phase extraction cartridges.The LMG was determined by high performance liquid chromatography.The recoveries of the method was 84.5%-92.1%, the relative standard deviation （RSD）values for repeatability was 4.09%-5.26%, the detection limit was 0.5 μg/kg.Thus, this is an accurate method which has simple pretreatment, and it is applicable for quickly and accurate determination of large number of samples. |
