“…Furthermore, the decrease of organic matter content, soil fertility and plant growth in surrounding areas of cement and chemicals industries is one of the negative effects of pollutants emitted by industrial anthropogenic activities, these led to degradation of soil quality and long term biogeochemical cycles distrubance. [55] In this contexte, polyphenols act as biological molecules involved in stress protection for plants. These include abiotic stressors such as extreme temperatures, drought, flood, light, salt, and heavy metals, [56][57][58] regardless of the origin of the studied plant species, the accumulation of phenolic compounds in the reveals the fact that the leaves could constitute a reservoirs of polyphenols.…”

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.
