Abstract
Objective: To investigate the preliminary phytochemical screening and in vitro antioxidant activity of methanol extract of Tropaeolum majus L. (T. majus) seeds.
Methods: Phytochemical screening was performed by using standard methods. The antioxidant study was done by using in vitro method such as 2, 2-diphenyl-2-picrylhydrazyl (DPPH).
Results: Qualitative phytochemical analysis reveals presence of alkaloids, flavonoids and tannins. The extract showed moderate antioxidant activity against the tested method.
Conclusion: There is an indication that seeds of T. majus contains important phytochemicals and an antioxidant capacity comparable with standard antioxidant compounds that may be linked to its beneficial effects on health.
Keywords: Tropaeolum majus L, phytochemical, antioxidant, DPPH.
