The study was aimed to evaluate the antioxidant potential of Adina cordifolia and Cassia angustifolia. Dry leaf powder of Adina cordifolia and Cassia angustifolia was sequentially extracted in organic solvents with increasing polarity by Soxhlet apparatus. The total phenolic content (TPC) was determined by Folin-Ciocalteau method. Antioxidant potential of extracts was determined by DPPH method, Reducing power assay and Nitric oxide scavenging assay. The results revealed that Cassia angustifolia has more phenolic content as compared to the Adina cordifolia. In C. angustifolia, ethanolic extract exhibited the highest phenolic content with 106 µg/ml followed by ethyl acetate, chloroform and petroleum ether extract with total phenolic contents of 69.4 µg/ml, 45.3 µg/ml and 40.2 µg/ml respectively. DPPH assay, Reducing power assay and Nitric oxide scavenging assay revealed that Cassia angustifolia has more antioxidant potential than Adina cordifolia with ethanolic extract showing the 87.7%, 90.3% and 77.86 % absorbance in the respective assays. The study confirms that the both the medicinal plants have high antioxidant potential.
