The leaves of the plant are steeped in hot water to make a beverage known as mate. The present study aimed to quantify and compare the content of selected elements in dried leaves and stems of I. paraguariensis (originating from Paraguay, Argentina, and Brazil) available in the market in Poland and determine the amount of these elements and bioactive compounds that pass into the infusion prepared from them. The contents of the following antioxidant compounds were assessed: neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, caffeic acid, 4-feruloylquinic acid, isochlorogenic acid, rutoside, astragalin, caffeine, and indole derivatives. All the tested samples showed the presence of elements such as magnesium, zinc, copper, iron, and manganese. The highest antioxidant activity was determined for infusion prepared from yerba mate samples from Brazil. Drinking approximately 1 L of the infusion a day will partially cover the daily requirement of these elements and bioactive compounds. The highest content of organic compounds with antioxidant properties (phenolic compounds and caffeine) was found in yerba mate infusions from Brazil.<\/jats:p>","DOI":"10.3390\/antiox11020371","type":"journal-article","created":{"date-parts":[[2022,2,13]],"date-time":"2022-02-13T20:32:30Z","timestamp":1644784350000},"page":"371","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":49,"title":["Yerba Mate as a Source of Elements and Bioactive Compounds with Antioxidant Activity"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7883-9736","authenticated-orcid":false,"given":"El\u017cbieta","family":"Rz\u0105sa-Duran","sequence":"first","affiliation":[{"name":"Branch in Krak\u00f3w\u2014Hospital Pharmacy, Maria Sklodowska-Curie National Research Institute of Oncology, Garncarska 11 Str., 31-115 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9125-250X","authenticated-orcid":false,"given":"Agata","family":"Kryczyk-Poprawa","sequence":"additional","affiliation":[{"name":"Department of Inorganic and Analytical Chemistry, Faculty of Pharmacy, Jagiellonian University Medical College, Medyczna 9 Str., 30-688 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dawid","family":"Drabicki","sequence":"additional","affiliation":[{"name":"Department of Inorganic and Analytical Chemistry, Faculty of Pharmacy, Jagiellonian University Medical College, Medyczna 9 Str., 30-688 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adrian","family":"Podkowa","sequence":"additional","affiliation":[{"name":"Department of Inorganic and Analytical Chemistry, Faculty of Pharmacy, Jagiellonian University Medical College, Medyczna 9 Str., 30-688 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7325-9254","authenticated-orcid":false,"given":"Katarzyna","family":"Su\u0142kowska-Ziaja","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Botany, Faculty of Pharmacy, Jagiellonian University Medical College, Medyczna 9 Str., 30-688 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3010-679X","authenticated-orcid":false,"given":"Agnieszka","family":"Szewczyk","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Botany, Faculty of Pharmacy, Jagiellonian University Medical College, Medyczna 9 Str., 30-688 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8354-211X","authenticated-orcid":false,"given":"Katarzyna","family":"Ka\u0142a","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Botany, Faculty of Pharmacy, Jagiellonian University Medical College, Medyczna 9 Str., 30-688 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"W\u0142odzimierz","family":"Opoka","sequence":"additional","affiliation":[{"name":"Department of Inorganic and Analytical Chemistry, Faculty of Pharmacy, Jagiellonian University Medical College, Medyczna 9 Str., 30-688 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Piotr","family":"Zi\u0119ba","sequence":"additional","affiliation":[{"name":"Department of Horticulture, Faculty of Biotechnology and Horticulture, University of Agriculture in Krak\u00f3w, 29 Listopada 54, 31-425 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maciej","family":"Fidurski","sequence":"additional","affiliation":[{"name":"Department of Horticulture, Faculty of Biotechnology and Horticulture, University of Agriculture in Krak\u00f3w, 29 Listopada 54, 31-425 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5007-1486","authenticated-orcid":false,"given":"Bo\u017cena","family":"Muszy\u0144ska","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Botany, Faculty of Pharmacy, Jagiellonian University Medical College, Medyczna 9 Str., 30-688 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,2,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Gawron-Gzella, A., Chanaj-Kaczmarek, J., and Cielecka-Piontek, J.
