Development and validation of RP-HPLC method for the estimation of ascorbic acid in health drinks

Abstract

A simple, selective, linear, precise and accurate RP-HPLC method was developed and validated for rapid assay of Ascorbic acid in Health drinks. Isocratic elution at a flow rate of 0.9ml/min was employed on a symmetry C18 (250x4.6mm, 0.5μ in particle size) at ambient temperature. The mobile phase consisted of Water with acetic acid: methanol 95:5% (v/v). The UV detection wavelength was 245 nm and 20μl sample was injected. The retention time for Ascorbic acid was 4.61+_ 0.22 min. The percentage RSD for precision and accuracy of the method was found to be less than the method was validated as per the ICH guidelines. The method was successfully applied for routine analysis of Ascorbic acid in Health drinks.
