As natural products of plant origin, essential oils (EOs) are an outstanding option due to their reported bioactivity. In this research, ten EOs of Labiatae species were extracted by steam distillation and its chemical constituents were identified by gas chromatography-mass spectrometry (GC-MS). A total of 123 chemical compounds, including alkenes, phenols, aldehydes and ketones, were identified. The results of antioxidant activity carried out through DPPH free radical scavenging (DPPH) and ferric reducing antioxidant power (FRAP), showing that EOs of Ocimum basilicum Linn. (ObEO), Thymus mongolicus Ronn. (TmEO), Origanum vulgare Linn. (OvEO) and Mosla chinensis Maxim. (McEO) have strong antioxidant activities. Their 50%-inhibitory concentration (IC50) value was &lt;1.00, 1.42, 1.47 and 1.92 \u03bcg\/mL, respectively; and their FRAP value was 1536.67 \u00b1 24.22, 271.84 \u00b1 4.93, 633.71 \u00b1 13.14 and 480.66 \u00b1 29.90, respectively. The results of filter paper diffusion showing that McEO, OvEO and TmEO inhibition zone diameter (IZD) are all over 30 mm. The results of two-fold dilution method showed that McEO, OvEO and TmEO have strong antibacterial activities against Staphylococcus aureus (S. aureus) and their minimal inhibitory concentrations (MIC) value was 1 \u03bcL\/mL, 2 \u03bcL\/mL, and 2 \u03bcL\/mL, respectively. In conclusion, the results in this work demonstrate the possibility for development and application of EOs as potential feed additives.<\/jats:p>","DOI":"10.3390\/molecules25204862","type":"journal-article","created":{"date-parts":[[2020,10,23]],"date-time":"2020-10-23T02:01:42Z","timestamp":1603418502000},"page":"4862","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Chemical Composition and Bioactivity of Essential Oil of Ten Labiatae Species"],"prefix":"10.3390","volume":"25","author":[{"given":"Mengting","family":"Liu","sequence":"first","affiliation":[{"name":"Hunan Key Laboratory of Traditional Chinese Veterinary Medicine, Hunan Agricultural University, Changsha 410128, China"},{"name":"College of Veterinary Medicine, Hunan Agricultural University, Changsha 410128, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Feiya","family":"Luo","sequence":"additional","affiliation":[{"name":"Hunan Key Laboratory of Traditional Chinese Veterinary Medicine, Hunan Agricultural University, Changsha 410128, China"},{"name":"College of Veterinary Medicine, Hunan Agricultural University, Changsha 410128, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhixing","family":"Qing","sequence":"additional","affiliation":[{"name":"Hunan Key Laboratory of Traditional Chinese Veterinary Medicine, Hunan Agricultural University, Changsha 410128, China"},{"name":"College of Veterinary Medicine, Hunan Agricultural University, Changsha 410128, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huichao","family":"Yang","sequence":"additional","affiliation":[{"name":"Hunan Key Laboratory of Traditional Chinese Veterinary Medicine, Hunan Agricultural University, Changsha 410128, China"},{"name":"College of Veterinary Medicine, Hunan Agricultural University, Changsha 410128, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiubin","family":"Liu","sequence":"additional","affiliation":[{"name":"Hunan Key Laboratory of Traditional Chinese Veterinary Medicine, Hunan Agricultural University, Changsha 410128, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9103-5492","authenticated-orcid":false,"given":"Zihui","family":"Yang","sequence":"additional","affiliation":[{"name":"Hunan Key Laboratory of Traditional Chinese Veterinary Medicine, Hunan Agricultural University, Changsha 410128, China"},{"name":"College of Veterinary Medicine, Hunan Agricultural University, Changsha 410128, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianguo","family":"Zeng","sequence":"additional","affiliation":[{"name":"Hunan Key Laboratory of Traditional Chinese Veterinary Medicine, Hunan Agricultural University, Changsha 410128, China"},{"name":"College of Veterinary Medicine, Hunan Agricultural University, Changsha 410128, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,10,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"282","DOI":"10.1136\/vr.139.12.282","article-title":"Usage of antibacterial and antiparasitic drugs in animals in Sweden between 1988 and 1993","volume":"139","author":"Bjornerot","year":"1996","journal-title":"Veter- Rec."},{"key":"ref_2","first-page":"20","article-title":"Veterinary antibiotics use, occurrence of antibiotic resistance pathogen and its antibiotic resistance genes in animal production: An overview","volume":"10","author":"Sui","year":"2015","journal-title":"Asian J.
