According to the WHO, approximately 80% of the world’s population uses herbal drugs as part of their normal health case routine. In this present work an attempt was made to estimate Gallic acid present in Marketed Herbal formulation of Amla tablet, Neem tablet, Baheda churna, Herbal tea, Mixed fruit Jam and Herbal chyawanprash. The developed method was found to be simple, precise, and economic, can be utilized for routine method for quantification of Gallic acid. The proposed spectrophotometric method is validated in terms of linearity, accuracy, precision and reproducibility.
