Abstract
Amaranthus herbaceous corolla and rarely small or uplifting shrubs, with simple or intermittent leaves, no earlobes, pseudo spike flowers and flowers are usually bisexual or monocular actinomorphs. There are ten different species of Amaranthus in different regions of Iran, two of which are called Amaranthus viridis L. and Amaranthus graecizans subsp graecizans L. weed in Sistan region. The amounts of phenolic compounds in different parts of the plant were determined by Folin covalent inoculation using a spectrophotometer in a 765 nm wavelength using a standard curve in mg/g of extract per gram. Total flavonoids by colorimetric method Aluminum chloride will be used todetermine the antioxidant activity using the DPPH method. The anthocyanin content is read at 550 nm in length using aspectrophotometer. The results of this study on two types of Amaranthus show that methanolic extract of different parts of these two species during growth stages contain different antioxidant levels and concentrations, with the highest content of phenol, flavonoids, and entocyanin, and the accumulation of free radicals is related to leaves. The highest amount of carbohydrates in the root, the highest chlorophyll a in the leaf production stage, the highest amount of chlorophyll b in the reproductive stage of leaf, the highest amount of carotenoids in the breeding stage and the most proline content of the seed.
