The analyzed species included: Anacyclus clavatus Desf., Erica multiflora L., Cistus salvifolius L., Centaurium erythraea Rafn., Marrubium vulgare L., Lavandula stoechas L., Artemisia campestris L., Origanum majorana L., Salvia officinalis L., and Pistacia lentiscus L. All the extracts were chromatographed on the RP18 W plates with methanol\u2013water\u2013acetic acid (48 + 47 + 5, v\/v\/v) mobile phase. Upon completion of the chromatographic development and the drying step, the plates were stained with a chloroform solution of 2, 2-diphenyl-1-picrylhydrazyl radical (DPPH\u2022). An image processing protocol, with use of Sorbfil TLC Videodensitometer, was applied to quantitatively measure the activity of polyphenols and to screen complex samples for the presence of free radical scavengers. The activity of the individual compounds was compared with that of rutin, used as a standard. The TLC-DPPH\u2022 test showed that C. salvifolius had the most potent antioxidant activity, as it possessed the highest activity coefficient (calculated as the sum of the areas under the peaks of all active compounds\/area under peak of rutin). The proposed procedure may be used to differentiate potent chain-breaking antioxidants and compounds propagating radical chain reactions.<\/jats:p>","DOI":"10.5740\/jaoacint.sgeel_euch","type":"journal-article","created":{"date-parts":[[2014,9,30]],"date-time":"2014-09-30T23:44:58Z","timestamp":1412120698000},"page":"1291-1298","source":"Crossref","is-referenced-by-count":8,"title":["Free Radical Scavenging Fingerprints of Selected Aromatic and Medicinal Tunisian Plants Assessed by Means of TLC-DPPH\u2022 Test and Image Processing"],"prefix":"10.1093","volume":"97","author":[{"given":"Salma Kammoun","family":"El Euch","sequence":"first","affiliation":[{"name":"High School of Food Industries in Tunis, 58 Alain Savary St, 1003 Tunis, Tunisia; and Laboratory of Structural Organic Chemistry, Faculty of Sciences of Tunis, 2092 El Manar, Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u0141ukasz","family":"Cie\u015bla","sequence":"additional","affiliation":[{"name":"Medical University of Lublin, Department of Inorganic Chemistry, Chodzki 4a, 20 093 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nabiha","family":"Bouzouita","sequence":"additional","affiliation":[{"name":"High School of Food Industries in Tunis, 58 Alain Savary St, 1003 Tunis, Tunisia; and Laboratory of Structural Organic Chemistry, Faculty of Sciences of Tunis, 2092 El Manar, Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2019,11,27]]},"container-title":["Journal of AOAC INTERNATIONAL"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/academic.oup.com\/jaoac\/article-pdf\/97\/5\/1291\/32424881\/jaoac1291.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/academic.oup.com\/jaoac\/article-pdf\/97\/5\/1291\/32424881\/jaoac1291.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,3,19]],"date-time":"2020-03-19T18:20:38Z","timestamp":1584642038000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/jaoac\/article\/97\/5\/1291-1298\/5654757"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,9,1]]},"references-count":0,"journal-issue":{"issue":"5","published-online":{"date-parts":[[2019,11,27]]},"published-print":{"date-parts":[[2014,9,1]]}},"URL":"https:\/\/doi.org\/10.5740\/jaoacint.sgeel_euch","relation":{},"ISSN":["1060-3271","1944-7922"],"issn-type":[{"value":"1060-3271","type":"print"},{"value":"1944-7922","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2014,9,1]]},"published":{"date-parts":[[2014,9,1]]}}}
