Abstract

Halophyte plants can easily adapt in saline habitats, salt marshes, mudflats, and inland deserts. This kind of plants can be utilized as new sources of natural antioxidants. The goal of the present investigation was to examine the antioxidant of methanolic extracts of the Tamarix articulata in southern Algeria (ElOued). Colorimetric methods were applied to assess the total phenolic and flavonoid contents, HPLC analysis was used to identify the individual polyphenols, and the amount was also determined, while scavenging assays of DPPH, FRAP, ABTS, β- carotène and total antioxidant capacity of methanol leaves extract from Tamarix articulate were used to measure antioxidant capacities . The resulted findings showed that total phenolic contents and flavonoid from the extract of this plant were found to be 398.42 ± 5.21 mg GAE /g DW for phenolic content, and 120.55 ± 3.41 mg CE/g DW. The HPLC analysis showed that there were at least 8 remarkable phenolic compounds of leaves extract, and the most important ones included vanillic acid, naringin, and caffeic acid. The seeds of this natural plant can be a promising source for new drugs because they contain antioxidant properties and phenolic compounds.
