Adequate antioxidant intake is a key factor of proper diet. The study aimed to assess the antioxidant\/antiradical capacities of Cucurbita fruits (18 cultivars of the species: C. maxima Duch., C. moschata Duch., C. pepo L., and C. ficifolia Bouch\u00e9) grown in central Europe. The analyses were based on the FRAP (ferric reducing antioxidant power), CUPRAC (cupric ion reducing antioxidant capacity), and DPPH (2,2-diphenyl-1-picrylhydrazyl radical) assays. The content of phenolic compounds and \u03b2-carotene was evaluated with HPLC (high performance liquid chromatography), while the main macro- and micronutrients by ICP-OES (inductively coupled plasma mass spectrometry). The results revealed high intraspecies variability within the Cucurbita genus. The Japanese \u2018Kogigu\u2019 fruits were distinguished as extraordinary sources of phenolic compounds, including syringic and protocatechuic acids, catechin, and kaempferol. Another popular cultivar \u2018Hokkaido\u2019 exhibited the highest antioxidant and antiradical capacities. Most of the fruits proved to be rich sources of zinc and copper. The obtained data are discussed in the context of optimized nutrition of the elderly and suggest that Cucurbita fruits should become daily components of their diet.<\/jats:p>","DOI":"10.3390\/molecules25081792","type":"journal-article","created":{"date-parts":[[2020,4,15]],"date-time":"2020-04-15T04:01:46Z","timestamp":1586923306000},"page":"1792","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":54,"title":["Antioxidants and Health-Beneficial Nutrients in Fruits of Eighteen Cucurbita Cultivars: Analysis of Diversity and Dietary Implications"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8298-9419","authenticated-orcid":false,"given":"Anna","family":"Kostecka-Guga\u0142a","sequence":"first","affiliation":[{"name":"Department of Plant Biology and Biotechnology, Faculty of Biotechnology and Horticulture, University of Agriculture in Krakow, al.29 Listopada 54, 31-425 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Micha\u0142","family":"Kruczek","sequence":"additional","affiliation":[{"name":"Department of Plant Biology and Biotechnology, Faculty of Biotechnology and Horticulture, University of Agriculture in Krakow, al.29 Listopada 54, 31-425 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Iwona","family":"Ledwo\u017cyw-Smole\u0144","sequence":"additional","affiliation":[{"name":"Department of Plant Biology and Biotechnology, Faculty of Biotechnology and Horticulture, University of Agriculture in Krakow, al.29 Listopada 54, 31-425 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4968-8833","authenticated-orcid":false,"given":"Pawe\u0142","family":"Kaszycki","sequence":"additional","affiliation":[{"name":"Department of Plant Biology and Biotechnology, Faculty of Biotechnology and Horticulture, University of Agriculture in Krakow, al.29 Listopada 54, 31-425 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"932","DOI":"10.1126\/science.276.5314.932","article-title":"The Initial Domestication of Cucurbita pepo in the Americas 10,000 Years Ago","volume":"276","author":"Smith","year":"1997","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"715","DOI":"10.1590\/S0103-84782002000400028","article-title":"Origin and evolution of cultivated cultivars","volume":"32","author":"Bisognin","year":"2002","journal-title":"Ci\u00eancia Rural"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"423","DOI":"10.1007\/BF02935916","article-title":"Historical records, origins, and development of the edible cultivar groups of Cucurbita pepo (Cucurbitaceae)","volume":"43","author":"Paris","year":"1989","journal-title":"Econ.
