Abstract:

Vitamin "C" is one of the essential nutrients whose daily

recommended dose by World Health organization (WHO) is 20-30 mg. Several commercial juices indicate in their label “100% vitamin C". Do they really mean 100% of the recommended dose by WHO? In this experiment the juices are filtered and samples are injected into High Pressure Liquid Chromatography (HPLC). The amount of vitamin "C" is calculated from the standard graph obtained that uses standard ascorbic acid. The amount of vitamin C in different brands of various juices are compared using the standard graph.
