This study was carried out to determine and confirm of Dapsone in vegetables and fruits which were illegally used for freshness. We have developed a simple, rapid and precise method that Dapsone can be analyzed in the cabbages, grapes and strawberry by HPLC with photodiode array detector. Experimental subjects were included 15 cases of cabbages, 10 cases of grapes and 10 cases of strawberries purchased in Kangwon, Chungchong province and the Seoul area. The results were obtained that Dapaone in the experimental subject was separated completely within 10 min. Detection limit of Dapsone was 0.5 ng. Aberage recoveries from cabbages, grapes and strawberries were 93.3±0.26%, 92.5±0..37%, 91.4±0..65% respectively. 4 cases of cabbages were detected Dapsone and the amount was below the 0.3 ppm. There was not detected Dapsone in any grape and strawberry samples.
