The antibacterial activities of Ternstroemia\u00a0dentisepala and Ternstroemia lineata were evaluated for the first time against a panel of Gram-positive and Gram-negative bacteria that have implications for human health, including Enterococcus faecalis, Streptococcus agalactiae, Streptococcus pyogenes, Salmonella typhi, Pseudomonas aeruginosa, and Vibrio parahaemolyticus. Furthermore, the scavenging potential of the hydroalcoholic (HAEs) and total phenolic extracts (TPEs) from the leaves of both plants by a 2,2\u2019-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) assay (ABTS\u2022+) was determined. Also, the total phenolic contents of the HAEs using the Folin\u2013Ciocalteu reagent were assayed. T. dentisepala HAE and TPE were active against all bacterial strains tested, with a minimum inhibitory concentration between 1.0 and 6.0 mg\/mL, with the last one being the most active. However, the T. lineata extracts only demonstrated effectiveness against S. typhi and P. aeruginosa. The TPEs from T. dentisepala and T. lineata improved the activity by approximately 30% in all bacteria tested in comparison with the HAEs. The T. dentisepala HAE had a higher total phenolic content than the T. lineata extract, which was consistent with its ABTS\u2022+-scavenging activity. The two HAEs had different chemical profiles, mostly because of the types and amounts of phenolic compounds they contained. These profiles were obtained using thin-layer chromatography (TLC), high-performance liquid chromatography (HPLC), and proton nuclear magnetic resonance (1H NMR) experiments.<\/jats:p>","DOI":"10.3390\/plants13172515","type":"journal-article","created":{"date-parts":[[2024,9,9]],"date-time":"2024-09-09T03:04:18Z","timestamp":1725851058000},"page":"2515","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Antibacterial and Antioxidant Activities of Hydroalcoholic and Phenolic Extracts from Ternstroemia dentisepala and T. lineata Leaves"],"prefix":"10.3390","volume":"13","author":[{"given":"Alexis Uriel Soto","family":"D\u00edaz","sequence":"first","affiliation":[{"name":"Centro de Investigaci\u00f3n en Biotecnolog\u00eda, Universidad Aut\u00f3noma del Estado de Morelos, Cuernavaca 62210, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mar\u00eda Luisa","family":"Villarreal","sequence":"additional","affiliation":[{"name":"Centro de Investigaci\u00f3n en Biotecnolog\u00eda, Universidad Aut\u00f3noma del Estado de Morelos, Cuernavaca 62210, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0261-5573","authenticated-orcid":false,"given":"Marcelo Victorio-De los","family":"Santos","sequence":"additional","affiliation":[{"name":"Unidad Acad\u00e9mica de Ciencias Qu\u00edmicas Biol\u00f3gicas y Farmac\u00e9uticas, Universidad Aut\u00f3noma de Nayarit, Tepic 63190, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7055-0062","authenticated-orcid":false,"given":"Alexandre Toshirrico","family":"Cardoso-Taketa","sequence":"additional","affiliation":[{"name":"Centro de Investigaci\u00f3n en Biotecnolog\u00eda, Universidad Aut\u00f3noma del Estado de Morelos, Cuernavaca 62210, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2723","DOI":"10.1007\/s10531-004-2145-2","article-title":"Patterns of diversity, endemism and conservation: An example with Mexican species of Pentaphylacaceae Mirb.
