The phenolic compounds are well known phytochemicals found in all plants and these are responsible for antioxidant activity. These compounds are among the most widely occurring secondary metabolites in the plant kingdom. The present studies on optimisation of physico-chemical parameters like effects of different solvents, soaking time, extraction time with hexane, particle size, different solvent percentages, different volumes of hexane with ethanol and methanol as solvents, pH and different weight dosages for the extraction of Total Phenolic Content (TPC) from Medicinal herbs. The TPC concentration for optimized conditions of Terminaliachebula fruit, Amla fruit and Longan seeds were 36.5 µg/ml, 29.0 µg/ml and 34.0 µg/ml, respectively.
