Abstract
The ability to protect the body from damages caused by free radical induced oxidative stress is an essential property of antioxidants, so they are an indispensable substance. A variety of free radical scavenging antioxidants are found in several dietary sources. The main objective of this study focused on the screening of antioxidant activity of two Saharian Chenopodiaceae: Haloxylon scoparium and Traganum nudatum. The in vitro antioxidant activity was investigated with DPPH radical scavenging assay and reducing power assay of the Butanolic extracts of these species. The Total Phenolic Content (TPC) was evaluated according to the Folin-Ciocaltue assay and Gallic acid was used as standard. The Flavonoids content (TFC) was evaluated by using the Aluminum Chloride method. The findings showed that the Bu-OH extract of Haloxylon scoparium exhibited better values of antioxidant activity, total phenolic content and total flavonoid content compared to those of Traganum nudatum.
