    Abstract： This study optimized a gas chromatography method for determining Sodium N-cyclohexylsulfamate content in melon seeds. Results demonstrated that under the optimized conditions of 4mL sulfuric acid solution， 4mL sodium nitrite solution，and 5 shaking cycles，sodium N-cyclohexylsulfamate exhibited good linearity in the range of 6μg?mL^-1 to 600μg?mL^-1 ，with a correlation coefficient of 0.999 7. The recovery rate ranged from 93.5% to 99.2% ，and the relative standard deviations were 1.96% to 2.41% .The optimized method demonstrated advantages including lowreagent consumption，stable reproducibility，and high detection efficiency ......
