Nutritional and bioactive constituents and scavenging capacity of radicals in Amaranthus hypochondriacus

Abstract A. hypochondriacus leaves contained ample phytopigments including betalain, anthocyanin, β-xanthin, β-cyanin, and bioactive phytochemicals of interest in the industry of food. We have been evaluating the possibility of utilizing phytopigments of amaranth and bioactive constituents for making drinks. Therefore, we evaluated bioactive phytopigments and compounds including the potentiality of antioxidants in A. hypochondriacus leaves. A. hypochondriacus leaves have abundant protein, carbohydrates, and dietary fiber. We found considerable levels of inorganic minerals including magnesium, calcium, potassium (3.88, 3.01, 8.56 mg g −1 ), zinc, manganese, copper, iron (16.23, 15.51, 2.26, 20.57 µg g −1 ), chlorophyll b , chlorophyll ab chlorophyll a (271.08, 905.21, 636.87 μg g −1 ), scavenging capacity of radicals (DPPH, ABTS + ) (33.46, 62.92 TEAC…
