Phenolic Content, HPLC Analysis and Antioxidant Activity Extract from Tamarix gallica and Tamarix articulata Growing in Southeast of Algeria

The antioxidants synthesize such as butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT), are generally used in food processing industries; but, these compounds accountable for toxicities and carcinogenesis. [...]new and safe antioxidants from natural sources must be identified to replace these synthetic antioxidants12-13. Based on the traditional claims of Tamarix gallica and Tamarix articulata for the lack of scientific studies of its potential pharmacological properties, the objective of this study was to examine the phenolic content, flavonoid, HPLC profile of extract from Tamarix gallica and Tamarix articulata growing in Southeast of Algeria (El Oued). [...]the scavenging activities towards DPPH, ß-carotene, and total antioxidant activity were evaluated. The results showed high polyphenol contents in methanolic extract had the most potent radical scavenging capacity. [...]the concentrations of phenolic compounds were higher in the extract which could suggest that the high antioxidant capacity observed might be attributed mainly to the polyphenols. [...]it has been found that antioxidant molecules such as polyphenols, and flavonoids reduce the ability of free radicals43.
