| Abstract: | A HPLC method has been developed for the determination of pesticide malathion residue in cabbage. The research method showed that the liner relationship between peak area and sample size was satisfactory , the coefficient of correlation was 0.999 6; the relative standard deviation （RSD） was 0.21%（calculated by peak area）and 0.84% （calculated by concentration） respectively; the recovery was within 85.6% - 106.0%; the limit of detection （LOD） was 2.0 μg/L. |
