Medicinal Plants play a vital role in minimizing human illness and enhancing the quality of human life form ancient days itself. Plant-based medicines basically contain a natural substance, which promotes human health. In recent years, many researchers focus on medicinal plants and most of the pharmaceutical industry is vastly reliant on plant materials for the extraction of therapeutically important compounds. In the present investigation focused on qualitative, quantitative phytochemical and in vitro antioxidant activity of Cadaba fruticosa and Capparis spinosa leaves belonging to the family Capparidaceae. Among the different extracts studied, the chloroform leaf extract has high catalase activity. Peroxidase and Polyphenol activity was more in ethanol leaf extracts. Whereas Superoxide dismutase activity was high in aqueous extracts of both samples. Free radical scavenging activity of different leaf extracts was analyzed by using DPPH, nitric oxide and reducing power assay, whereas commercial antioxidant acts as standards. In DPPH assay C. fruticosa ethanol leaf extracts showed the best results than C.spinosa. In nitric oxide scavenging activity and reducing power assay ethanol extracts of both plants showed higher inhibition. The results suggest that C. fruiticosa and C.spinosa possess a good source of free radical scavenging compounds and the best supplements for the diseases associated with oxidative stress.
