It has also been used in cosmetics, as well as in refreshing drink preparations. In the present study, we have compared the aqueous extract effects of the leaves of the three Tunisian varieties of\n \n D. kaki<\/jats:italic>\n <\/jats:styled-content>\n , namely Triumph, Jiro, and Rojo Brillante, prepared by decoction and then filtered. The obtained filtrates were lyophilized and kept cold until analysis. Phytochemical profile and biological activities were performed on the freeze\u2010dried fractions of the different varieties of\n \n D. kaki<\/jats:italic>\n <\/jats:styled-content>\n . Analysis of the results shows that the leaf extracts of the three varieties are rich in total phenols and flavonoids (ranking: Rojo Brillante\u2009>\u2009Triumph\u2009>\u2009Jiro) and have a high antioxidant activity (EC\n 50<\/jats:sub>\n values of 3.8, 8.0 and 12.1\u2009\u03bcg\/mL respectively for Rojo Brillante, Triumph and Jiro). Using a quadrupole time\u2010of\u2010flight interface and high\u2010resolution tandem liquid chromatography, 29 secondary metabolites of\n \n D. kaki<\/jats:italic>\n <\/jats:styled-content>\n leaf decoctions were identified in the three varieties, including several polyphenols such as flavonoids, tannins, organic acids, and others. In addition, these extracts were found to inhibit the function of two key enzymes, acetylcholinesterase (IC\n 50<\/jats:sub>\n values of 58, 96 and 210\u2009\u03bcg\/mL respectively for Rojo Brillante, Triumph and Jiro) and inhibition percentages of 3\u2010hydroxy\u20103\u2010methylglutaryl\u2010CoA reductase were 61.44%, 57.35%, and 46.28% for Jiro, Triumph, and Rojo Brillante, respectively. However, we noted that these different extracts had no cytotoxic effect on human liver or breast cancer cells in culture until 10\u2009\u03bcg\/mL. The results reveal that the\n \n D. kaki<\/jats:italic>\n <\/jats:styled-content>\n leaves are a potential matrix for the launch of future nutraceuticals, cosmetics, and pharmaceutical specialties such as drugs to combat Alzheimer's disease or to reduce cholesterol levels, as well as an attractive source of ingredients beneficial to health. Comparative analysis of\n \n D. kaki<\/jats:italic>\n <\/jats:styled-content>\n leaves showed that the Rojo Brillante variety has a higher content of secondary metabolites than the other two varieties, thus increasing its antioxidant activity and enzyme inhibitory effect, although it is not as cytotoxic as the other two varieties.\n <\/jats:p>","DOI":"10.1002\/fsn3.70775","type":"journal-article","created":{"date-parts":[[2025,8,11]],"date-time":"2025-08-11T05:35:22Z","timestamp":1754890522000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Phytochemical Profile and Evaluation of Antioxidant Activity, Enzyme Inhibition and Cell Viability of Leaves Extracts of Three Tunisian Varieties of\n Diospyros kaki<\/i>\n L."],"prefix":"10.1002","volume":"13","author":[{"given":"Amna","family":"Mannai","sequence":"first","affiliation":[{"name":"Laboratory of Biodiversity, Biotechnologies and Climate Change (LR11\/ES09), Faculty of Sciences of Tunis Tunis El\u2010Manar University Tunis Tunisia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0073-6785","authenticated-orcid":false,"given":"Asma","family":"Ressaissi","sequence":"additional","affiliation":[{"name":"BioISI\u2013Instituto de Biosistemas e Ci\u00eancias Integrativas, Faculdade de Ci\u00eancias Universidade de Lisboa Lisboa Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4427-0208","authenticated-orcid":false,"given":"Abderrahmen","family":"Merghni","sequence":"additional","affiliation":[{"name":"Laboratory of Antimicrobial Resistance LR99\/ES09, Faculty of Medicine of Tunis University of Tunis El Manar Tunis Tunisia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5781-6946","authenticated-orcid":false,"given":"Hassiba","family":"Chahdoura","sequence":"additional","affiliation":[{"name":"Institut National des Technologies et des Sciences du El Kef Universit\u00e9 de Jendouba El Kef Tunisie"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8123-4743","authenticated-orcid":false,"given":"Wissem","family":"Mnif","sequence":"additional","affiliation":[{"name":"Department of Chemistry, College of Sciences at Bisha University of Bisha Bisha Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zarah","family":"Alelyani","sequence":"additional","affiliation":[{"name":"Department of Chemistry, College of Sciences at Bisha University of Bisha Bisha Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5368-4800","authenticated-orcid":false,"given":"Mossadok","family":"Ben\u2010Attia","sequence":"additional","affiliation":[{"name":"Environment Biomonitoring Laboratory (LR01\/ES14), Faculty of Sciences of Bizerte University of Carthage Bizerte Tunisia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2987-9798","authenticated-orcid":false,"given":"Safia","family":"EL\u2010Bok","sequence":"additional","affiliation":[{"name":"Laboratory of Biodiversity, Biotechnologies and Climate Change (LR11\/ES09), Faculty of Sciences of Tunis Tunis El\u2010Manar University Tunis Tunisia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7541-9613","authenticated-orcid":false,"given":"Maria Luisa","family":"Serralheiro","sequence":"additional","affiliation":[{"name":"BioISI\u2013Instituto de Biosistemas e Ci\u00eancias Integrativas, Faculdade de Ci\u00eancias Universidade de Lisboa Lisboa Portugal"},{"name":"Faculdade de Ci\u00eancias.
