With the purpose of making the first biochemical characterization of Moroccan onions, several biochemical components have been measured in eleven onion ecotypes. Onions were collected as seeds from different geographical origins and cultivated in the same environment, to eliminate the influence of the environment on biochemical expression. Moisture, total phenols, flavonoids, antioxidant activity, total and reducing sugars, and sulfur dioxide were the biochemical properties of interest. Except for moisture, the eleven onion ecotypes revealed a highly significant variation in terms of the studied biochemical characters. The total phenol and flavonoid content ranged from 5.94 to 11.22\u2009mg equivalent gallic acid\/g dry weight and 0.67 to 1.52\u2009mg equivalent quercetin\/g dry weight, respectively. The antioxidant activity of the studied onions showed a strong correlation with the polyphenols (\n                    <jats:inline-formula>\n                      <a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\">\n                        <a:msup>\n                          <a:mrow>\n                            <a:mi>R<\/a:mi>\n                          <\/a:mrow>\n                          <a:mrow>\n                            <a:mn>2<\/a:mn>\n                          <\/a:mrow>\n                        <\/a:msup>\n                        <a:mo>=<\/a:mo>\n                        <a:mn>0.7189<\/a:mn>\n                      <\/a:math>\n                    <\/jats:inline-formula>\n                    ), especially with the flavonoids (\n                    <jats:inline-formula>\n                      <c:math xmlns:c=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\">\n                        <c:msup>\n                          <c:mrow>\n                            <c:mi>R<\/c:mi>\n                          <\/c:mrow>\n                          <c:mrow>\n                            <c:mn>2<\/c:mn>\n                          <\/c:mrow>\n                        <\/c:msup>\n                        <c:mo>=<\/c:mo>\n                        <c:mn>0.8063<\/c:mn>\n                      <\/c:math>\n                    <\/jats:inline-formula>\n                    ). The sulfur dioxide content parted from 85.60 to 30.43\u2009ppm when measured using the Monier-Williams distillation method. The current results show that there is no correlation between total sugars and reducing sugars. In conclusion, these findings present a clear biochemical profile of Moroccan onion ecotypes, as well as confirm, for the first time, the presence of a clear variation between the biochemical profiles of Moroccan onion ecotypes, which could be useful for future valorization programs.\n                  <\/jats:p>","DOI":"10.1155\/2022\/2103151","type":"journal-article","created":{"date-parts":[[2022,3,9]],"date-time":"2022-03-09T18:20:10Z","timestamp":1646850010000},"page":"1-12","source":"Crossref","is-referenced-by-count":9,"title":["Characterization of the Biochemical Potential of Moroccan Onions (Allium cepa L.)"],"prefix":"10.1155","volume":"2022","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8772-9712","authenticated-orcid":true,"given":"Amal","family":"Brahimi","sequence":"first","affiliation":[{"name":"Biotechnology and Valorization of Biological Resources Laboratory, Faculty of Science of Meknes, University of Moulay Ismail, P.B. 11201 Zitoune, Meknes, Morocco"},{"name":"Cluster of Competency \u201cAgri-Food, Safety and Security\u201d IUC VLIR-UOS, Moulay Ismail University, Marjane 2, BP, 298 Meknes, Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5739-9508","authenticated-orcid":true,"given":"Mohamed","family":"El Ouardi","sequence":"additional","affiliation":[{"name":"Values, Society and Development Laboratory, Faculty of Letters and Human Sciences Ibn Zohr University, Agadir, Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amal","family":"Kaouachi","sequence":"additional","affiliation":[{"name":"Biotechnology and Valorization of Biological Resources Laboratory, Faculty of Science of Meknes, University of Moulay Ismail, P.B. 11201 Zitoune, Meknes, Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdelhakim","family":"Boudboud","sequence":"additional","affiliation":[{"name":"Biotechnology and Valorization of Biological Resources Laboratory, Faculty of Science of Meknes, University of Moulay Ismail, P.B. 11201 Zitoune, Meknes, Morocco"},{"name":"Cluster of Competency \u201cAgri-Food, Safety and Security\u201d IUC VLIR-UOS, Moulay Ismail University, Marjane 2, BP, 298 Meknes, Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7785-8991","authenticated-orcid":true,"given":"Lhoussain","family":"Hajji","sequence":"additional","affiliation":[{"name":"Biotechnology and Valorization of Biological Resources Laboratory, Faculty of Science of Meknes, University of Moulay Ismail, P.B. 11201 Zitoune, Meknes, Morocco"},{"name":"Cluster of Competency \u201cAgri-Food, Safety and Security\u201d IUC VLIR-UOS, Moulay Ismail University, Marjane 2, BP, 298 Meknes, Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1088-8782","authenticated-orcid":true,"given":"Hassan","family":"Hajjaj","sequence":"additional","affiliation":[{"name":"Biotechnology and Valorization of Biological Resources Laboratory, Faculty of Science of Meknes, University of Moulay Ismail, P.B. 11201 Zitoune, Meknes, Morocco"},{"name":"Cluster of Competency \u201cAgri-Food, Safety and Security\u201d IUC VLIR-UOS, Moulay Ismail University, Marjane 2, BP, 298 Meknes, Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4016-2699","authenticated-orcid":true,"given":"Hamid","family":"Mazouz","sequence":"additional","affiliation":[{"name":"Biotechnology and Valorization of Biological Resources Laboratory, Faculty of Science of Meknes, University of Moulay Ismail, P.B. 11201 Zitoune, Meknes, Morocco"},{"name":"Cluster of Competency \u201cAgri-Food, Safety and Security\u201d IUC VLIR-UOS, Moulay Ismail University, Marjane 2, BP, 298 Meknes, Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1080\/14620316.2020.1742586"},{"key":"2","author":"FAOSTAT","year":"2019"},{"key":"3","article-title":"Minist\u00e8re de l\u2019agriculture et la P\u00e8che maritime du D\u00e9veloppement rural et des Eaux et For\u00eats","author":"MAPMDREF","year":"2020"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1002\/ptr.1222"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/j.foodchem.2005.11.044"},{"issue":"1","key":"6","first-page":"635","article-title":"Determination of nutritional value and antioxidant from bulbs of different onion (Allium cepa) variety: a comparative study","volume":"4","author":"U.
