Abstract
In the several areas of Analytical chemistry such as biochemistry, pharmaceutical and food applications, the quantitative analysis of vitamin C has become an important subject. Vitamin C plays an important role in maintaining human health. During COVID -19 pandemic and current situation of various influenza viral infections Vitamin C possesses positive impacts on curing infection and it may play a protective role through improving the immune system. There are numerous methods for the determination of vitamin C in a variety of natural samples, biological fluids and pharmaceutical formulations. In the present work, it was aimed to determine and compare the Vitamin C concentration in some fresh fruits available in the middle region of Gujarat by using Titrimetric and UV spectrophotometric methods. It was found that vitamin C content of fruits commonly consumed at middle region of Gujarat; highest in Guava (108.50 mg/100gm by UV Spectrophotometric method and 157.38 mg/100gm by Redox titration method) and lowest in pineapple (16.24 mg/100gm by UV Spectrophotometric method and 20.53 mg/100gm by Redox titration method). These observations may serve as pointers on selection of fruits that can be consumed to match the requirement of vitamin C.
