DEVELOPMENT AND VALIDATION OF HPTLC METHOD FOR ESTIMATION OF ELLAGIC ACID IN ANTIDIABETIC HERBAL FORMULATION
A simple, sensitive, precise, rapid and reliable HPTLC method for the estimation of ellagic acid in marketed herbal formulation, Glucomap tablet was developed. In this method, precoated Silica Gel F254 Plates were used as stationary phase and Toluene: ethyle acetate: formic acid: methanol (3:3:8:2 v/v) as mobile phase. Developed chromatogram was scanned at 280 nm, the wavelength of maximum absorption for ellagic acid. The aptness of developed HPTLC method for estimation of ellagic acid was established by validating it as per the ICH guidelines. The content of ellagic acid in crude drug Terminalia arjuna and polyherbal formulation was also studied. The developed method has been successfully applied for the determination of ellagic acid in polyherbal formulation.
