Mediterranean saltbush Atriplexhalimus L. (Aranthaceae) from different bioclimatic arid zones (ten wild populations) were studied. Phenols contents, flavonoids, flavonols, tannins and anthocyanins were determined and then tested for their antioxidants, antidiabetic and anti‐acetylcholinesterase (AChE) activities. Levels of total polyphenols including flavonoids and flavonols, Tannins and anthocyanins were high and varied significantly among analyzed populations. Nine phenolic acids and four flavonoids were identified for the first time in the methanolic fraction and quantified by liquid high‐performance chromatography system HPLC (DAD). All extracts showed a substantial antioxidant activity, as assessed by DPPH assay (1,1‐diphenyl‐2‐picrylhydrazyl free radical) (IC50DPPH=147.3for population of Seliena), Ferric Reducing Antioxidant Power (FRAP; IC50FRAP=3.2 for populations of Sousse and Kairouan), and Chelation Fer test (IC50FerCh=1.5 µg/mL for populations of El‐hamma and Mednine). Atriplex halimus possessed a high inhibitory effect against α‐amylase activity (up to 2.6 mg ACE/gE), a moderate activity for α‐glucosidase (up to 91.0 mg ACE/gE) and AChE (up to 147.2 µg/mL) compared to standard. The analyzed populations were isolated and subdivided into three distinct groups, without any bioclimatic structuration. Enzymatic activities seem to be associated with the presence, in extracts, of other classes of compounds then phenols such as terpenes, sterols, saponins, coumarins and carotenoids.

Summary Water-crude oil emulsion causes challenges, which the petrochemical sector solves using efficient, ecologically friendly, and cost-effective demulsifying chemicals. With this work, we aim to solve the problem of the presence of water in Algerian oil after it has left the producing well by adding a natural material, widely used in the country, as an environmentally friendly demulsifier. Atriplex halimus L. leaf ATP powder (ATP-P) and leaf extract (E-ATP) were studied. We first characterized the two biosurfactants ATP-P and E-ATP by attenuated total reflectance (ATR), X-ray diffraction (XRD), and thermogravimetry analysis (TGA). The effect of ATP-P and E-ATP on the emulsion (water/oil) was studied by Fourier transform infrared spectroscopy (FTIR) analysis, microscopic, rheological behavior, interfacial tension (IFT), and bottle tests. The results obtained show the ability of the two biosurfactants E-ATP and ATP-P to separate water, with water separation reaching 99% in 30 minutes with 500 ppm of E-ATP, while ATP-P separates 98% in 92 minutes. The mechanism of action of the two compounds as biodemulsifiers can be traced back to the rheological study, which showed a 33% reduction in emulsion viscosity at 500 ppm; ATR-FTIR analysis also shows the disappearance of carbon-carbon and carbon-oxygen bonds, responsible for the reduction in oil viscosity. A decrease in surface tension by 41.48% by adding P-ATP and 57.95% by adding E-ATP contributed to the integration of water molecules and increased separation speed. Microscopic analysis shows an increase in the volume diameter of the water droplets, more than threefold when E-ATP is added and more than twofold when ATP-P is added.
