Development of High Performance Thin Layer Chromatography Method for Quantitation of Gallic Acid in Normacid Syrup: A Poly Herbal Formulation

摘要

Normacid syrup consisiting of 17 ingredients, used in the treatment of hyperacidity and gastritis. Gallic acid is one of the phytoconstituent present in Normacid syrup- a poly herbal formulation. In the present study an attempt has been made to develop a HPTLC method for quantitative estimation of gallic acid in dried fruits used in formulations. This HPTLC method was found to be reproducible, accurate, precise and detect gallic acid at nanogram level. The developed HPTLC method would be an important tool in the quality control method of poly herbal formulation.
