Colorimetric method for the determination of Paromomycin Sulfate in Bulk and Dosage forms using Ascorbic acid


A simple and accurate colorimetric method was developed for the estimation of paromomycin sulphate (PM) in bulk and pharmaceutical formulations. The method was based on generation of colored complex from reaction between PM and ascorbic acid having analytically useful maxima at 390 and 530 nm. The factors such as concentration of ascorbic acid and heating… (More)
