This study aimed to quantify flavonoids and polyphenols in white garlic and black garlic extracts, evaluate their antioxidant power, assess their antibacterial activity against specific pathogenic bacteria, and examine their antiproliferative effects on U87 glioblastoma cancer cells. The extraction was conducted using distilled water, methanol, and ethanol, and the quantification of bioactive compounds, antioxidant activity using the 2,2-diphenyl-1-picrylhydrazyl test, antibacterial activity, and antiproliferative activity using the MTT assay. The findings of this research showed significantly higher levels of phenolic acids and flavonoids in black garlic compared to raw garlic, with methanol extracts containing the highest concentration of flavonoids (2.33 mg quercetin equivalent\/g DM) and polyphenols (63.25 mg ascorbic acid equivalent\/g DM). Both white garlic and black garlic extracts displayed excellent antioxidant activity, while methanol extracts of black garlic exhibited the highest inhibition percentages (96.3% \u00b1 0.36). Methanol extracts of black garlic also demonstrated effective antibacterial activity, while the antiproliferative effects were significant for all extracts on U87 glioblastoma cancer cells. These findings highlight black garlic as a promising source of compounds with antiproliferative, antibacterial, and antioxidant properties, although the concentration of bioactive compounds may vary among different extracts.<\/jats:p>","DOI":"10.1089\/jmf.2023.0229","type":"journal-article","created":{"date-parts":[[2025,6,13]],"date-time":"2025-06-13T11:58:23Z","timestamp":1749815903000},"page":"768-775","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Therapeutic and Biological Properties of White Garlic and Black Garlic Extracts (\n                    <i>Allium sativum<\/i>\n                    L.): A Comparative Analysis"],"prefix":"10.1177","volume":"28","author":[{"given":"Halima","family":"Ben Hmad","sequence":"first","affiliation":[{"name":"Laboratory Asyllia Polla of Interdisciplinary Research in Health Sciences, body and health axis, Mahmoud El Materi University, Tunis, Tunisia."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Najet","family":"Sellami","sequence":"additional","affiliation":[{"name":"Higher Institute of Medical Technologies of Tunis, Tunis, Tunisia."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Houda","family":"Ben Jemaa","sequence":"additional","affiliation":[{"name":"Higher School of Health Sciences and Technics, University of Tunis El Manar, Tunis, Tunisia."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohamed Montassar","family":"Lasram","sequence":"additional","affiliation":[{"name":"Laboratory of Microorganisms and Actives Biomolecules, Department of Biology, Faculty of Sciences, University of Tunis El Manar, Tunis, Tunisia."},{"name":"Laboratory of Neurophysiology, Cellular Physiopathology and Bioressources Valorization, University of Tunis El Manar, Tunis, Tunisia."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,8,1]]},"reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1093\/ecam\/nem096"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.3390\/medicines2030251"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.4103\/0973-7847.95849"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.3390\/molecules23010105"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.3892\/ol.2022.13245"},{"key":"e_1_3_4_7_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00203-021-02248-z"},{"key":"e_1_3_4_8_2","doi-asserted-by":"publisher","DOI":"10.3945\/ajcn.2008.26142"},{"key":"e_1_3_4_9_2","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.41.10.2286"},{"key":"e_1_3_4_10_2","doi-asserted-by":"publisher","DOI":"10.3390\/foods10112703"},{"key":"e_1_3_4_11_2","doi-asserted-by":"publisher","DOI":"10.3390\/molecules14062167"},{"key":"e_1_3_4_12_2","doi-asserted-by":"publisher","DOI":"10.1556\/018.69.2018.2.5"},{"key":"e_1_3_4_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0076-6879(99)99017-1"},{"key":"e_1_3_4_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0023-6438(95)80008-5"},{"key":"e_1_3_4_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpha.2015.11.005"},{"key":"e_1_3_4_16_2","doi-asserted-by":"publisher","DOI":"10.4103\/1735-5362.258495"},{"key":"e_1_3_4_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jfda.2016.05.011"},{"key":"e_1_3_4_18_2","doi-asserted-by":"publisher","DOI":"10.3390\/molecules26165028"},{"key":"e_1_3_4_19_2","doi-asserted-by":"publisher","DOI":"10.3390\/molecules24112194"},{"key":"e_1_3_4_20_2","doi-asserted-by":"publisher","DOI":"10.3390\/antiox10101611"},{"key":"e_1_3_4_21_2","doi-asserted-by":"publisher","DOI":"10.3109\/08923973.2011.649288"},{"key":"e_1_3_4_22_2","first-page":"443","article-title":"Physiological activity and antioxidative effects of aged black garlic (Allium sativum L.) extract","volume":"40","author":"Jang EK","year":"2008","unstructured":"Jang EK, , Seo JH, , Lee SP.
