Present study was carried out to assess nutraceutical values of wild edible herb I. aquatica with its antioxidant potentials. Proximate analysis of the moisture, ash and crude fat content reveals 82.54±1.68%, 0.34±0.23% and 2.54±0.39%, respectively. The total phenolics content was estimated and found highest in I. aquatica (44.27±1.92mg/g). Potassium content was also highest in I. aquatica (1003.95±17.37 mg/kg). I. aquatica showed the lowest value of Iron and Manganese (1.85±0.23 mg/kg, 8.83 ±1.86 mg/kg). The mineral analysis revealed high amount of potassium (1003.95±17.37 mg/kg), calcium (92.89±8.12 mg/kg). Phytochemistry of I. aquatica also indicated the presence of alkaloids, flavonoids, phenols, steroids, saponins and cardiac glycosides. The plant contains a very good amount of vitamin C (39.1±1.65 mg/100gm). The plant also showed a good dose dependent antioxidant activity against both DPPH and H2O2 molecules. The outcome of the study indicates that proximate composition, mineral contents, vitamin contents and antioxidant properties of this plant could be used for the nutritional purpose.
