Objective: In order to study the contect of sodium cyclamate in jellies. Method: Using ring amino sulfonate sodium hypochlorite derived reaction occurs under acidic conditions to generate N-,N-dichloro-cyclohexane,and then hexane extracted ODC-C14 column,methanol(V):water(V)=80:20 as mobile phase separation,the flow rate was 1.0mL/min, the injection volume was 20ul,the detection wavelength of 314nm.Result This high-efficiency liquid chromatography determination of the concentration of sodium cyclamate in the linear relationship between the 0-300ug/ml,the correlation coefficient was 0.9995 above, and require accuracy and good reproducibility. The recovery rate of sodium cyclamate was 80%-120%,the coefficient of variation less than 10%.Conclusion:The method is rapid, simple,highly sensitive and with less interference, which is suitable for the detection of cyclamate in jellies.
