Cucumis mel L. var reticulatus Naudin and Averrhoa bilimbi L. are known to possess significant chemicals that offer health benefits, including the presence of vitamin C. Vitamin C, classified as a water-soluble vitamin, possesses the potential to exert a significant influence in the prevention of several diseases. The objective of this experiment was to analyze the concentrations of vitamin C present in Cucumis mel L. var reticulatus Naudin and Averrhoa bilimbi L. using the UV-Vis spectrophotometry method. The test was performed qualitatively with FeCl3 reagen and quantitatively with 2,6-dichlorophenol indophenol using UV-Vis spectrophotometry. The results showed that the levels of vitamin C in Cucumis mel and Averrhoa bilimbi fruit were 44.523 mg/100g and 48.666 mg/100 g, respectively.
