Derivatized HPTLC Method for Simultaneous Estimation of Glucosamine, Vitamin C and Vitamin E in Tablets
Subscribe/Renew Journal
An accurate, precise and derivatized HPTLC method has been developed for the simultaneous estimation of Glucosamine, Vitamin C and Vitamin E in tablet formulation. In this method standard and sample solutions of Glucosamine, Vitamin C and Vitamin E were applied on pre-coated silica gel 60F254 TLC plate, and developed using ethanol:Acetic acid (9:1 v/v), as mobile phase and derivatized using Iodine vapor. The drugs on the plate were scanned at 500 nm. The dynamic linearity range was 20-100 μg/spot for Glucosamine, 2-10 μg/spot for Vitamin C and 0.2-1 μg/spot for Vitamin E. The method was validated for precision, accuracy and reproducibility.
