Chem."],"abstract":"<jats:p>This study explores the therapeutic potential of <jats:italic>J. regia<\/jats:italic> from Morocco through an in-depth phytochemical analysis and biological evaluations using <jats:italic>in vitro<\/jats:italic>, <jats:italic>in vivo<\/jats:italic>, and <jats:italic>in silico<\/jats:italic> approaches. The extracts of <jats:italic>J. regia<\/jats:italic> were obtained through decoction and Soxhlet extraction, utilizing water and a water-ethanol mixture as extraction solvents. Phenolic compounds, flavonoids, condensed tannins, and hydrolyzable tannins were quantified using spectrophotometric methods. Chromatographic analysis by HPLC\/MS enabled the identification and characterization of the main bioactive compounds. Biological activities were assessed through antioxidant (DPPH, FRAP, TAC), antimicrobial (MIC, MBC), anticoagulant (prothrombin time and activated partial thromboplastin time), and antidiabetic (inhibition of \u03b1-amylase and \u03b1-glucosidase enzymes, <jats:italic>in vivo<\/jats:italic> tests) assays. <jats:italic>In silico<\/jats:italic> simulations were conducted to study the molecular interactions between the significant compounds and their biological targets. The extracts, obtained by decoction and Soxhlet extraction, revealed a richness in bioactive compounds, notably pedunculagin (45.12%), hydrojuglone glucoside (14.51%), and gallic acid (5.18%), with high concentrations of polyphenols (42.105\u00a0mg GAE\/g) and flavonoids (14.888\u00a0mg QE\/g). Antioxidant assays, including TAC, FRAP, and DPPH, revealed significant antioxidant activity. Additionally, the aqueous extract exhibited notable antimicrobial efficacy, demonstrating minimum inhibitory concentrations (MICs) of 150\u00a0\u03bcg\/mL against <jats:italic>Acinetobacter baumannii<\/jats:italic> and <jats:italic>Shigella<\/jats:italic> sp., and 2,500\u00a0\u03bcg\/mL against <jats:italic>Aspergillus niger<\/jats:italic> and particular <jats:italic>Candida<\/jats:italic> species. The anticoagulant activity was evidenced by prolonged prothrombin time (98.9\u00a0s) and activated partial thromboplastin time (134.2\u00a0s at 11.5\u00a0mg\/mL), and the antidiabetic activity was confirmed by the inhibition of \u03b1-amylase (EC<jats:sub>50<\/jats:sub> = 104.8\u00a0\u03bcg\/mL) and \u03b1-glucosidase (EC<jats:sub>50<\/jats:sub> = 12.12\u00a0\u03bcg\/mL) enzymes, as well as by a reduction in postprandial hyperglycemia in treated rats (400\u00a0mg\/kg). <jats:italic>In silico<\/jats:italic> simulations revealed a strong affinity of pedunculagin for key biological targets, supporting its therapeutic potential. In conclusion, <jats:italic>Juglans regia<\/jats:italic> emerges as a promising natural resource for applications in the pharmaceutical, nutraceutical, and cosmetic fields, although clinical studies are required to validate its efficacy and safety.<\/jats:p>","DOI":"10.3389\/fchem.2025.1638205","type":"journal-article","created":{"date-parts":[[2025,9,4]],"date-time":"2025-09-04T11:42:12Z","timestamp":1756986132000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Nutraceutical potential of moroccan Juglans regia: phytochemical profiling and multi-modal evaluation of bioactivities"],"prefix":"10.3389","volume":"13","author":[{"given":"Aziz","family":"Drioiche","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Omkulthom","family":"Al kamaly","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Soukayna","family":"Baammi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Khalid","family":"Zibouh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rachid","family":"Amaiach","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laila","family":"Bennani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"El Ouali Lalami","family":"Abdelhakim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahde","family":"El Imache","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fadoua","family":"EL Makhoukhi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sevser","family":"Sahpaz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Touriya","family":"Zair","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,9,4]]},"reference":[{"key":"B2","doi-asserted-by":"publisher","first-page":"145","DOI":"10.34172\/jcvtr.2023.31835","article-title":"The hypoglycemic effects of Juglans regia L. internal septum in type 2 diabetic patients: a double-blind, randomized, placebo-controlled clinical trial","volume":"15","author":"Afra","year":"2023","journal-title":"J.
