The presence of phytochemical constituents was checked by qualitative screening using different chemical tests indicated the occurrence of alkaloids, phenols, tannins, flavonoids, terpenoids and sulphates while carbohydrates, steroids and carbonates were absent. Quantitively, total content of phenol and total content of flavonoid methanolic extract was evaluated using method named Folin-Ciocalteau’s and named aluminum trichloride method respectively. We concluded that leaves have highest flavonoids and phenolic content seeds whereas have least phenolic content and stem have lowest flavonoids content. Antioxidant activities of methanolic extracts of leaves, stems, roots and seeds of different plant parts were estimated using two methods from % age inhibition of DPPH and hydrogen peroxide we concluded that in both methods leaves had greater antioxidant activity and seeds had lesser antioxidant activity.Antibacterial potential was evaluated by Diffusion well method against two bacterial strains as Rhodococcus species and Pseudomonas species using ampicillin as a reference standard. By the calculation of zone of inhibition, concluded that leaves exhibited highest antibacterial effect and lowest by seeds. The results obtained from study indicate that leaves of oxalis corniculata have highest pharmacological applications for further study. Copyright@ International Science Community Association
