Abstract :Abstract
The present study explores the antioxidant potential of the leaf tissue of a promising accession of a seed amaranth, Amaranthus hypochondriacus (Accession no. IC47434). GC-MS separated fractions of hydroethanolic leaf extract have complex chemical composition with several -OH rich phytochemicals. The hydroethanolic leaf extracts of mature leaf tissue of the experimental accession of Amaranthus hypochondriacus exhibited several major constituents. Most of these phytochemicals are rich in -OH and may therefore be used as terminators of free radical chain reaction or may chelate transition metal ions required for Fenton type reaction for the generation of more toxic ROS. Quantitative antioxidant profiling of methanolic leaf extracts based on in-vitro radical scavenging property (DPPH radical scavenging assay) and estimations of monophenol, diphenol, total polyphenol, flavonoids, anthocyanin, betacyanin and carotenoids also revealed significant antioxidant potential of the leaf extract of the experimental accession.
