The formulation is dispensed for anaemia and jaundice. It is observed that the consistency and taste of the formulation varies from manufacturer to manufacturer. Three in- house batches of Drakshavaleha was prepared. These batches were evaluated for physicochemical parameters such as extractive value, ash value, loss on drying, pH, total solid content, amount of reducing sugar, fat content etc. In present communication, a TLC- method was developed for the standardization of Drakshavaleha by quantitative estimation of major antioxidant compounds, piperine, as marker. The developed method was validated with respect to linearity, precision, accuracy, and robustness. Stability study was performed according to the ICH guidelines. The results of three in- house batches were found in close proximation with each other.
