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 FolinCiocaltue 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.

Abstract

The Moringa oleifera (Moringaceae) is one of these important plants, distributed in many tropical and subtropical countries, known with its medical uses of high nutritional value it is called the "tree of life". The Composition profile of the dichloromethane extract of the flowers of Moringa oleifera growing in Algerian desert was studied by capillary gas chromatography-mass spectrometry (GC-MS). thirty four Compounds were identified; Within the limits of the applied experimental conditions and by interpreting the mass spectra obtained and comparing it with the mass spectra of the reference materials, we record the possibility of the presence of the following chemical compounds: Hydrocarbons, Organic acids, Esters, Aldehydes Aromatic compounds and Nitrocyclic compounds, which major compounds are : (Z) - (9,17Octadecadienal (100%), Octadecanoic acid (60.4%), Heneicosane (10.186%), (Z)-9 Octadecenoic acid (12.711%), Heptadecanoic acid (13.742%), Hexadecane, 2,6,10,14-tetramethyl (18.988%), Heptadecane (14.866%) and Eicosane (17.535%). Analysis of QSAR descriptor from the results revealed that major constituents of the dichloromethane extract of Moringa olifera (L.) flowers
