In this work, for the first time, the volatile chemical composition of peels and juices from four different Citrus species (C. junos, Citrus \u00d7 aurantium, C. aurantium \u2018Bizzarria\u2019 and C. medica \u2018Florentina\u2019, commonly known as Yuzu jeune, Oni Yuzu, Bizzarria orange and Florence cedar, respectively) was investigated by Solid-Phase Microextraction-Gas Chromatography\/Mass Spectrometry (SPME-GC\/MS) technique and the antiradical activity was also examined. The results showed that limonene and \u03b3-terpinene were the main volatile substances detected both in the juices and in the peels, followed by other minority compounds responsible for the phyto-complex of the unique aromas which characterize each individual analyzed Citrus species. Principal component analysis (PCA), performed on volatile compounds, showed both some correlation as well as a clear separation between the juice and the peel of each species. Among them, Oni Yuzu juice was found to be the richest in total polyphenols and flavonoids while its capacity to scavenge ABTS\u2022+ and DPPH\u2022 radicals was similar to that of Yuzu Jeune and Bizzarria orange.<\/jats:p>","DOI":"10.3390\/molecules26175378","type":"journal-article","created":{"date-parts":[[2021,9,6]],"date-time":"2021-09-06T13:18:26Z","timestamp":1630934306000},"page":"5378","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["A Comparative Study of the Chemical Composition by SPME-GC\/MS and Antiradical Activity of Less Common Citrus Species"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7557-9473","authenticated-orcid":false,"given":"Sara","family":"Vitalini","sequence":"first","affiliation":[{"name":"Department of Agricultural and Environmental Sciences, Universit\u00e0 degli Studi di Milano, 20133 Milan, Italy"},{"name":"Phytochem Lab, Department of Agricultural and Environmental Sciences, Universit\u00e0 degli Studi di Milano, 20133 Milan, Italy"},{"name":"National Interuniversity Consortium of Materials Science and Technology (INSTM), 50121 Firenze, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5063-1236","authenticated-orcid":false,"given":"Marcello","family":"Iriti","sequence":"additional","affiliation":[{"name":"Department of Agricultural and Environmental Sciences, Universit\u00e0 degli Studi di Milano, 20133 Milan, Italy"},{"name":"Phytochem Lab, Department of Agricultural and Environmental Sciences, Universit\u00e0 degli Studi di Milano, 20133 Milan, Italy"},{"name":"National Interuniversity Consortium of Materials Science and Technology (INSTM), 50121 Firenze, Italy"},{"name":"Center for Studies on Bioispired Agro-Environmental Technology (BAT Center), Universit\u00e0 degli Studi di Napoli \u2018Federico II\u2019, 80055 Portici, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vittorio","family":"Vinciguerra","sequence":"additional","affiliation":[{"name":"Department for Innovation in Biological Systems, Food and Forestry, University of Tuscia, 01100 Viterbo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8535-0533","authenticated-orcid":false,"given":"Stefania","family":"Garzoli","sequence":"additional","affiliation":[{"name":"Department of Drug Chemistry and Technology, Sapienza University, 00185 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,9,4]]},"reference":[{"key":"ref_1","unstructured":"(2021, June 16).
