In order to improve the knowledge on this genus, the aim of the present study was to correlate, for the first time, the phenolic composition of different <jats:italic>Quercus ilex<\/jats:italic> L. plant tissues (leaves in two maturation stages, acorns, teguments and cotyledons) and different extraction procedures with scavenging and anticholinesterase activities. The hydromethanolic and aqueous extracts obtained showed strong radical scavenging activity against DPPH, superoxide anion radical and nitric oxide radical, leaves exhibiting higher total phenolic content and revealing the best antioxidant properties, followed by tegument and acorns. Concerning the phenolic profile, fifteen compounds were identified and quantified by HPLC\u2010DAD, ranging from 1568.43 to 45,803.16\u00a0mg\/kg dried extract. The results indicate that <jats:italic>Q<\/jats:italic>.\u00a0<jats:italic>ilex<\/jats:italic> can be a source of strong antioxidant phenolic compounds with possible interest for food and pharmaceutical industries.<\/jats:p>","DOI":"10.1002\/cbdv.201600187","type":"journal-article","created":{"date-parts":[[2016,9,2]],"date-time":"2016-09-02T00:05:58Z","timestamp":1472774758000},"source":"Crossref","is-referenced-by-count":16,"title":["<i>Quercus ilex<\/i> L.: How season, Plant Organ and Extraction Procedure Can Influence Chemistry and Bioactivities"],"prefix":"10.1002","volume":"14","author":[{"given":"Lila","family":"Hadidi","sequence":"first","affiliation":[{"name":"Department of Physico\u2010Chemical Biology Faculty of Nature and Life Sciences University of Bejaia Bejaia 06000 Algeria"}]},{"given":"Louiza","family":"Babou","sequence":"additional","affiliation":[{"name":"Department of Food Science Faculty of Nature and Life Sciences University of Bejaia Bejaia 06000 Algeria"}]},{"given":"Farid","family":"Zaidi","sequence":"additional","affiliation":[{"name":"Department of Food Science Faculty of Nature and Life Sciences University of Bejaia Bejaia 06000 Algeria"}]},{"given":"Patr\u00edcia","family":"Valent\u00e3o","sequence":"additional","affiliation":[{"name":"REQUIMTE\/LAQV Laborat\u00f3rio de Farmacognosia Departamento de Qu\u00edmica Faculdade de Farm\u00e1cia Universidade do Porto Rua de Jorge Viterbo Ferreira, no. 228 PT\u20104050\u2010313 Porto Portugal"}]},{"given":"Paula B.","family":"Andrade","sequence":"additional","affiliation":[{"name":"REQUIMTE\/LAQV Laborat\u00f3rio de Farmacognosia Departamento de Qu\u00edmica Faculdade de Farm\u00e1cia Universidade do Porto Rua de Jorge Viterbo Ferreira, no. 228 PT\u20104050\u2010313 Porto Portugal"}]},{"given":"Clara","family":"Grosso","sequence":"additional","affiliation":[{"name":"REQUIMTE\/LAQV Laborat\u00f3rio de Farmacognosia Departamento de Qu\u00edmica Faculdade de Farm\u00e1cia Universidade do Porto Rua de Jorge Viterbo Ferreira, no. 228 PT\u20104050\u2010313 Porto Portugal"}]}],"member":"311","published-online":{"date-parts":[[2016,12,23]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.indcrop.2013.09.015"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.fct.2011.10.061"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.foodchem.2010.04.020"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0378-8741(00)00399-8"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jep.2003.10.009"},{"key":"e_1_2_6_7_1","first-page":"183","volume":"33","author":"S\u00f6hretoglu D.","year":"2004","journal-title":"J.
