A study work was carried out to evaluate antioxidant activity, antibacterial activity, proximate analysis and micronutrients analysis of eight edible weeds namely Celosia argentea, Trianthema portulacastrum, Amaranthus viridis, Solanum nigrum, Medicago denticulata Portulaca oleracea, Digera arvense and Mentha longifolia. The results of conducted research work indicates that all the weed plants under observation showed variable values of micro and macro nutrient, antioxidents and antimicrobial activity. Plants of Celosia argentea showed highest amount of protein (43.1 g/L), moisture content (10.43 %) and zinc (0.382 mg/100g), Trianthema portulacastrum exhibates highest amount of ash (18.2 %) and manginese (0.192 mg/100g) while Amaranthus viridis had highest fiber (4.53 g/m2). The plants of Medicago denticulata found to have highest carbohydrates (62.86 mg/L) and copper (0.287 mg/100g), whereas Portulaca oleracea showed highest fat (25.2 kcal/g), magnisum (42.112 mg/100g) and calcium (119.92 mg/100g), while on the other hand plants of Mentha longifolia had highest iron content (5.22 mg/100g). Results of antioxidant activity showed that palnts of Digera arvense have highest antioxidant activity (83.5 mg) while the plants of Solanum nigrum had showed highest zone of inhibition (7.71) against ralstonia solanacearum.
