The sample treatment includes a previous solid\u2010liquid extraction stage and subsequent parallel microextraction approaches to preconcentrate total aroma content and the free fraction. Thus, the extraction of the total content of analytes requires previous enzymatic hydrolysis of the bound forms. For preconcentration, chloroform (250 \u03bcl) and acetonitrile (1.5\u00a0ml) were added to 10\u00a0ml of the sample extract in the presence of 0.5\u00a0g sodium chloride. The absence of matrix effect in the samples allowed quantification against aqueous external standards. Limits of detection ranged between 5 and 30\u00a0ng\/g, depending on the compound. Method accuracy was studied through recovery assays, with recoveries in the 82\u2013115% range being obtained. Relative standard deviations for repeatability studies were lower than 12%. Four different samples of grapes were analyzed, being quantified linalool in its free form at concentrations in the 359\u2013470\u00a0ng\/g range, and benzyl alcohol, 2\u2010phenylethanol, and linalool oxide I and II in their bound forms between 52 and 464\u00a0ng\/g.<\/jats:p>","DOI":"10.1002\/jssc.202200181","type":"journal-article","created":{"date-parts":[[2022,6,17]],"date-time":"2022-06-17T10:39:06Z","timestamp":1655462346000},"page":"2996-3004","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Free and glycosylated aroma compounds in grapes monitored by solid\u2010liquid extraction and dispersive liquid\u2010liquid microextraction combined with gas chromatography\u2010mass spectrometry"],"prefix":"10.1002","volume":"45","author":[{"given":"Ainhoa","family":"Oller\u2010Ruiz","sequence":"first","affiliation":[{"name":"Department of Analytical Chemistry, Faculty of Chemistry, Regional Campus of International Excellence \u201cCampus Mare Nostrum\u201d University of Murcia  Murcia Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5219-3711","authenticated-orcid":false,"given":"Pilar","family":"Vi\u00f1as","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry, Faculty of Chemistry, Regional Campus of International Excellence \u201cCampus Mare Nostrum\u201d University of Murcia  Murcia Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1795-3476","authenticated-orcid":false,"given":"Manuel","family":"Hern\u00e1ndez\u2010C\u00f3rdoba","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry, Faculty of Chemistry, Regional Campus of International Excellence \u201cCampus Mare Nostrum\u201d University of Murcia  Murcia Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9","family":"Fenoll","sequence":"additional","affiliation":[{"name":"Sustainability and Quality Group of Fruit and Vegetable Products Murcia Institute of Agri\u2010Food Research and Development.
