Sweet orange fruit contains vitamin C which is quite high. This study aims to determine and compare the results of vitamin C levels in sweet oranges using the Na 2,6 Dichlorophenol Indophenol titration method and spectrophotometry. The content of vitamin C using Na 2.6 Dichlorophenol Indophenol titration is 0.042%, while the content of vitamin C in sweet oranges using the UV-Vis spectrophotometry method produces levels of 0.351%. These results, shows that the levels of vitamin C obtained by using the UV-Vis spectrophotometry method are higher than those obtained by the iodometric method.]]>
