QUANTITATION OF GALLIC ACID IN ACACIA NILOTICA L. PODS BY HPTLC

Abstract

The pods of Acacia nilotica L. are traditionally used for versatile medical applications and are rich in polyphenolics and flavonoids. The pods powder is available in the market either as branded or unbranded products and it is imperative that their quality be assessed by a valid analytical method. This method will help to ensure the quality of the pod powder and can be used as a standardization tool prior to incorporation in finished herbal products. We report here a simple, precise and reproducible analytical method for standardization of the pods and solvent extracts of A. nilotica by HPTLC using gallic acid as the reference standard. This method can be used as a quality control tool to assess the quality of these pods when used as raw materials as such or in formulations.
