The composition of the extracts was determined by chromatographic methods and compared to that of conventional maceration of the plant. The optimum total phenolic contents for the aboveground part and the roots were 193.9 and 174.4 \u03bcg\/g, respectively. These results were achieved at a subcritical water temperature of 150 \u00b0C, an extraction time of 180 min, and a water\/plant ratio of 0.1, for both parts of the plant. Principal component analysis revealed that the roots contained mainly phenols, ketones, and diols, with the aboveground part mostly alkenes and pyrazines, whereas the extract from maceration contained mainly terpenes, esters, furans, and organic acids. The quantification of selected phenolic substances showed that subcritical water extraction compared favorably to maceration, especially with respect to pyrocatechol (1062 as compared to 10.2 \u03bcg\/g) and epicatechin (1109 as compared to 23.4 \u03bcg\/g). Furthermore, the roots of the plant contained twice as much of these two phenolics compared to the aboveground part. Subcritical water extraction of O. mutabilis is an environmentally friendly method that can extract selected phenolics at higher concentrations compared to maceration.<\/jats:p>","DOI":"10.3390\/molecules28052314","type":"journal-article","created":{"date-parts":[[2023,3,3]],"date-time":"2023-03-03T01:43:00Z","timestamp":1677807780000},"page":"2314","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Subcritical Water Extraction of Onosma mutabilis: Process Optimization and Chemical Profile of the Extracts"],"prefix":"10.3390","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2589-8585","authenticated-orcid":false,"given":"Selda Do\u011fan","family":"\u00c7alhan","sequence":"first","affiliation":[{"name":"Department of Pharmaceutical Biotechnology, Faculty of Pharmacy, Mersin University, Mersin 33169, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bahar","family":"Meryemo\u011flu","sequence":"additional","affiliation":[{"name":"Central Research Laboratory, Cukurova University, Adana 01330, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pelin","family":"Ero\u011flu","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Science Faculty, Mersin University, Mersin 33110, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bar\u0131\u015f","family":"Sa\u00e7l\u0131","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Science Faculty, Mersin University, Mersin 33110, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4983-065X","authenticated-orcid":false,"given":"Dimitrios","family":"Kalderis","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Hellenic Mediterranean University, 73100 Chania, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"410","DOI":"10.1016\/j.sajb.2021.03.022","article-title":"Onosma gracilis (Trautv.) and O. oreodoxa (Boiss. & Heldr.): Phytochemistry, in silico docking, antioxidant and enzyme inhibitory activities","volume":"143","author":"Baltaci","year":"2021","journal-title":"S.
