- W4385366321 abstract "sodium saccharin, sodium cyclamate, sodium benzoate, potassium sorbate, tartrazine and sunset yellow. A total of six essence syrup samples were obtain from wholesale and supermarket in Medan City and given code H, I, J, K, L and M. Optimization parameter include void volume, wavelengths, pH of mobile phase, composition of mobile phase, flow rate and column temperature. Validation parameter include linearity, limit of detection, limit of quantitation, accuracy, precision and selectivity. The method obtained was used for the simultaneous determination of the concentration of a mixture of sodium saccharin, sodium cyclamate, sodium benzoate, potassium sorbate, tartrazine and sunset yellow in essence syrup samples.The results of reseach showed that the optimum conditions were void volume 30% with three-wavelength analysis, i.e: 200 nm for sodium cyclamate; 220 nm for sodium saccharin, sodium benzoate and potassium sorbate; 450 nm for tartrazine and sunset yellow. Mobile phase of phosphate buffer pH 4.5 and methanol 75: 25 (v / v), flow rate of 1.0 ml/min, column temperature of 30oC. The retention time of tartrazine, sodium saccharin, sodium cyclamate, sunset yellow, sodium benzoate and potassium sorbate were 0,941 minute; 1,589 minute; 2,748 minute; 3,703 minute; 5,516 minute; 8,583 minute, respectively. The results of validation showed good linearity. Limits of detection of sodium saccharin, sodium cyclamate, sodium benzoate, potassium sorbate, tartrazine and sunset yellow were 0,03634 ppm; 2,66306 ppm; 0,23882 ppm; 0,16542 ppm, 0,14939 ppm; and 0,19097 ppm, respectively. Limit of quantitation of sodium saccharin, sodium cyclamate, sodium benzoate, potassium sorbate, tartrazine and sunset yellow were 0,12113 ppm; 8,87687 ppm; 0,79608 ppm; 0,55141 ppm, 0,49795 ppm; and 0,63655 ppm, respectively. The result of accuracy test was 94,27% - 105,95% as percent recovery, repeatability test was 0,11% - 1,53% as %RSD, reproducibility test was 0,04 – 1,94% as %RSD, and selectivity showed good results. The result showed that potassium sorbate is not contained in essence syrup samples. Tartrazine and sunset yellow don’t exceed the maximum limit of use in essence syrup samples. Some essence syrup samples contains of sodium saccharin, sodium cyclamate, and sodium benzoate exceed maximum limit of usage." @default.
