Hydrosols (HDs) were extracted by hydrodistillation from seven species of Lamiaceae, including Thymus vulgaris, Thymus mongolicus, Mentha \u00d7 piperita, Melissa officinalis, Rosmarinus officinali, Salvia elegans, and Leonurus artemisia. In total, 369 volatile components were determined and analyzed by gas chromatography\u2013mass spectrometry (GC-MS). Among them, alcohols (2.86\u201328.48%), ethers (2.46\u201310.69%), and phenols (0.11\u201321.78%) constituted a large proportion, mainly linalool (0.28\u201319.27%), eucalyptol (0.16\u20136.97%), thymol (0\u201319.54%), and carvacrol (0\u201326.82%). Multivariate statistical analyses were performed and 27 differential metabolites were screened. Three different methods (ABTS+\u2022, DPPH\u2022, and FRAP) were used to determine the in vitro antioxidant activity of seven HDs. Thymus vulgaris hydrosols (Tv HDs) and Thymus mongolicus hydrosols (Tm HDs) had the strongest antioxidant activity and their stronger antioxidant capacity was related to their high levels of phenolic constituents, mainly thymol. The antioxidant activity of the other five Lamiaceae HDs was associated with their high alcohol (mainly linalool and eucalyptol) content, and the alcohol constituents may synergistically affect their antioxidant capacity. Therefore, the present study suggests that Lamiaceae plants can be utilized as antioxidant products or antioxidants in different industrial sectors including pharmaceuticals, food, cosmetics, and agrochemicals.<\/jats:p>","DOI":"10.3390\/molecules29010145","type":"journal-article","created":{"date-parts":[[2023,12,27]],"date-time":"2023-12-27T02:58:12Z","timestamp":1703645892000},"page":"145","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Investigation of Volatile Components and Assessment of Antioxidant Potential in Seven Lamiaceae Plant Hydrosols"],"prefix":"10.3390","volume":"29","author":[{"given":"Ziwei","family":"Xin","sequence":"first","affiliation":[{"name":"College of Landscape Architecture and Arts, Northwest A&F University, Yangling 712100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenjia","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Landscape Architecture and Arts, Northwest A&F University, Yangling 712100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weizong","family":"Yang","sequence":"additional","affiliation":[{"name":"College of Landscape Architecture and Arts, Northwest A&F University, Yangling 712100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yajie","family":"Li","sequence":"additional","affiliation":[{"name":"College of Landscape Architecture and Arts, Northwest A&F University, Yangling 712100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lixin","family":"Niu","sequence":"additional","affiliation":[{"name":"College of Landscape Architecture and Arts, Northwest A&F University, Yangling 712100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8931-2171","authenticated-orcid":false,"given":"Yanlong","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Landscape Architecture and Arts, Northwest A&F University, Yangling 712100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"A\u0107imovi\u0107, M., Stankovi\u0107 Jeremi\u0107, J.S., Miljkovi\u0107, A., Rat, M., and Lon\u010dar, B.
