Juncus maritimusan extremophilous microorganism speciesknown for its medicinal properties was collected in the Biskra region with the aim of its valorization. The volume size of polyphenols, flavonoids and condensed tannins was performed using the Folin-Ciocalteu method, aluminum trichloride and vanillin respectively. The volume of Polyphenols was 127.73±0.20 μg EAG/mg ES, the volume offlavonoids was 16.42±0.42 μg EQ/mg ES, and the volume ofcondensed tannins was 10.10±0.35 μg EC/mg ES. The results of the antioxidant activity tests using the DPPH and ABTS methods reveal that the ethyl acetate extract had the highest activity in both tests. The results of the in vitro anti-inflammatory activity, using the BSA protein denaturation assay, showed that the percentage of denaturation inhibition wasproportional to the concentration of the extract. At a concentration of 5 mg/mL, the inhibition percentage of the extract were 82.03 % and 80.23 %, respectively,which wereclose tothose of theanti-inflammatory drug Diclofenac.Furthermore, molecular docking simulations indicated that Berberine has high binding affinity to the targets COX-2 and PLA-2 In fact,bioisosteric replacement is being usedto discover new analogs of Berberine. Finally, ADME-Tox predictions demonstrated that this compound and its analogs were not hepatotoxic. This result may lead to the selection ofBerberine and its analogs as active compounds with anti-inflammatory and antioxidant effects., (© 2024 Wiley-VHCA AG, Zurich, Switzerland.)
