Despite its ethnopharmacological relevance, its phytochemistry and biological activities, particularly in Iraq, are underexplored. This study investigated the phytochemical composition of H. articulatum extracts and evaluated their antioxidant and anti-Helicobacter pylori activities, supported by molecular docking and in silico ADMET analysis. Methanol\/water and ethyl acetate extracts from roots and aerial parts were analyzed using LC-HRMS\/MS. Antioxidant capacity was measured via DPPH assay, and anti-H. pylori activity was assessed using broth microdilution. Molecular docking targeted bacterial isoleucyl-tRNA synthetase, and ADMET predictions were carried out with SwissADME and ADMETlab. Phytochemical profiling identified 32 compounds, including phenolamides, flavonoids, alkaloids, and triterpenoid glycosides. Root extracts exhibited stronger antioxidant and antibacterial effects than aerial parts. Ethyl acetate extracts were inactive. Phenolamides, N-caffeoyltyramine, and sinapoyltyramine, present in the extract, showed significant activity (MICs = 54 \u00b1 0.92 and 74 \u00b1 1.05 \u00b5g\/mL). Docking supported their strong binding to the target enzyme. ADMET results indicated good oral bioavailability and low toxicity. This study is the first to report the anti-H. pylori activity of H. articulatum and to characterize its Iraqi chemotype through advanced metabolomics. The findings highlight the plant\u2019s potential as a source of multifunctional phytochemicals with antioxidant and antibacterial applications, warranting further preclinical development and toxicological investigation.<\/jats:p>","DOI":"10.3390\/molecules30173520","type":"journal-article","created":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T11:41:12Z","timestamp":1756381272000},"page":"3520","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Phytochemical Characterization and Anti-Helicobacter pylori Potential of Haloxylon articulatum Extracts: Antioxidant Activity and Molecular Docking Insights"],"prefix":"10.3390","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9867-8554","authenticated-orcid":false,"given":"Reyadh","family":"Al-Rashidi","sequence":"first","affiliation":[{"name":"Department of Basic Science, College of Dentistry, University of Kut, Wasit 52001, Iraq"},{"name":"Department of Biochemistry, Faculty of Medicine, University of Sousse, Sousse 4002, Tunisia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hana","family":"Nasrallah","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, Faculty of Medicine, University of Sousse, Sousse 4002, Tunisia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amal","family":"Bouazzi","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Sahloul University Hospital, Medicine Faculty of Sousse, University of Sousse, Sousse 4002, Tunisia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6662-0689","authenticated-orcid":false,"given":"Amira","family":"Za\u00efri","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, Faculty of Medicine, University of Sousse, Sousse 4002, Tunisia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"697","DOI":"10.2307\/2258560","article-title":"Autecology of Haloxylon Articulatum in Syria","volume":"60","author":"Sankary","year":"1972","journal-title":"J.
