Previous study exhibited that the leaves of amaranths were rich in quality protein particularly containing high lysine, which is the limiting essential amino acid in cereals. Fast growing and high tolerance to drought, marginal land and extreme climate had made this nutritious plant as promising crop for human future. This research reported the DPPH radical scavenging activity of leaves of 16 amaranth’s accessions from personal collection and USDA that were grown in polybags. The leaves were harvested before flowering. Total phenol and inhibition capacity of DPPH free radicals IC 50 as indication for radical scavenging activity were measured by using uv-vis spectrophotometer. The results indicated that Amaranthus tricolor from USA and A. hybridus from Zimbabwe was the weakest and the strongest IC 50 with 13.83 mgml and 1.30 mgml, respectively. Correlation was not observed between IC 50 and total phenol content. This result highlighted the importance of leafy amaranth as potential sources of antioxidant.

1. Introduction

Amaranths are popular leafy vegetables in the diet among the people in Asia particularly Indonesia. Amaranth is species that spreads widely in tropical to subtropical regions and found up to 2000 m above sea level [1]. Around 70 species of amaranth have been recorded worldwide harvested as grain, vegetable, forage, ornamental or grow wild as weed [2]. Increasing amount of amaranth grain has been used in food industries benefiting from its high level of oil and protein with particularly its excellent amino acids composition [3]. The leaves of amaranths are also good sources of protein and amino acid especially lysine [4]. Fast growing and high tolerance to drought, marginal land and extreme climate has made this nutritious plant as promising crop for human future [5].
