The aim of this study was to evaluate the ripening-stage-dependent compositional changes in some Hungarian-bred sour cherry varieties (\u201camarelle\u201d type \u2018Korai pipacs\u2019, \u201cmorello\u201d types \u2018\u00c9rdi b\u0151term\u0151\u2019 and \u2018\u00dajfeh\u00e9rt\u00f3i f\u00fcrt\u00f6s\u2019), with a special view on biologically active compounds (anthocyanins, polyphenols, vitamin C, melatonin), organic acids, sugars, and antioxidant characteristics. The measured soluble solid content varied within a narrower range than reported in the literature, whereas the total acid content and soluble solid content were consistent with previous data. As the analyses were based on samples from a single year (2022), potential year-to-year variability should be considered when interpreting the results. The \u201cmorello\u201d type varieties reached a higher amount of different sugar compounds than the \u201camarelle\u201d type variety. Among the examined organic acid compounds, malic acid was detected in the highest quantity (176.75 to 669.44 mg 100 mL\u22121). The vitamin C data (5.74 to 13.46 mg 100 mL\u22121) had similarity to the literature data. The \u201camarelle\u201d type \u2018Korai pipacs\u2019 reached the highest antioxidant content (131.11 mM AS L\u22121) in the third picking time. Among the naturally occurring pigments the \u201cmorello\u201d type, straining sour cherries reached a higher amount (113.71 \u00b5g mL\u22121 in \u2018\u00c9rdi b\u0151term\u0151\u2019 and 59.4 \u00b5g mL\u22121 in \u2018\u00dajfeh\u00e9rt\u00f3i f\u00fcrt\u00f6s\u2019 of cyanidin glucosides), than the observed \u201camarelle\u201d type (23.42 \u00b5g mL\u22121 in \u2018Korai pipacs\u2019 of cyanidin glucosides). Melatonin was detected in all examined varieties (1.56 to 13.25 ng mL\u22121).<\/jats:p>","DOI":"10.3390\/plants15050713","type":"journal-article","created":{"date-parts":[[2026,2,27]],"date-time":"2026-02-27T08:31:19Z","timestamp":1772181079000},"page":"713","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Changes in Biologically Active Compounds During the Ripening Period in Selected Hungarian-Bred Sour Cherry Varieties (Prunus cerasus L.)"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4981-0867","authenticated-orcid":false,"given":"Gitta","family":"Ficzek","sequence":"first","affiliation":[{"name":"Department of Fruit Growing, Institute of Horticultural Sciences, Hungarian University of Agriculture and Life Sciences, Villanyi u. 29-43, 1118 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gergely","family":"Simon","sequence":"additional","affiliation":[{"name":"Department of Fruit Growing, Institute of Horticultural Sciences, Hungarian University of Agriculture and Life Sciences, Villanyi u. 29-43, 1118 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matyas","family":"Gergely","sequence":"additional","affiliation":[{"name":"Department of Fruit Growing, Institute of Horticultural Sciences, Hungarian University of Agriculture and Life Sciences, Villanyi u. 29-43, 1118 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9197-514X","authenticated-orcid":false,"given":"Sherif","family":"Mehmeti","sequence":"additional","affiliation":[{"name":"Department of Fruit Growing, Institute of Horticultural Sciences, Hungarian University of Agriculture and Life Sciences, Villanyi u. 29-43, 1118 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-0440-4924","authenticated-orcid":false,"given":"Verina","family":"Krasniqi","sequence":"additional","affiliation":[{"name":"Department of Fruit Growing, Institute of Horticultural Sciences, Hungarian University of Agriculture and Life Sciences, Villanyi u. 29-43, 1118 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edit","family":"Mali-G\u00e1sp\u00e1r","sequence":"additional","affiliation":[{"name":"Department of Fruit Growing, Institute of Horticultural Sciences, Hungarian University of Agriculture and Life Sciences, Villanyi u. 29-43, 1118 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L\u00e1szl\u00f3","family":"Komma","sequence":"additional","affiliation":[{"name":"Department of Fruit Growing, Institute of Horticultural Sciences, Hungarian University of Agriculture and Life Sciences, Villanyi u. 29-43, 1118 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gyorgy","family":"Vegvari","sequence":"additional","affiliation":[{"name":"Institute of Viticulture and Oenology, Faculty of Natural Sciences, Eszterh\u00e1zy K\u00e1roly Catholic University, Eszterh\u00e1zy t\u00e9r 1, 3300 Eger, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7911-5860","authenticated-orcid":false,"given":"Geza","family":"Bujdos\u00f3","sequence":"additional","affiliation":[{"name":"Research Centre of Fruit Growing, Institute of Horticultural Sciences, Hungarian University of Agriculture and Life Sciences, Park u. 2, 1223 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,27]]},"reference":[{"key":"ref_1","unstructured":"FAOSTAT (2025, March 01).
