Samples of mate tea leaves were collected from an experiment conducted under agronomic control at Ind\u00fastria e Com\u00e9rcio de Erva\u2010Mate Bar\ufffdo LTDA, Brazil. Six solvents with increasing polarities (<jats:italic>n<\/jats:italic>\u2010hexane, toluene, dichloromethane, ethyl acetate, acetone, and methanol) were used in this investigation. Chemical analysis of the extracts was performed by GC coupled with a mass spectrometer detector. The identification and quantification were accomplished by coinjections of certified standards. The results showed that no significant differences in the qualities of the extracts were noticed regarding the extraction methods. On the other hand, the PLE technique was found to be more effective for the extractions of caffeine, phytol, palmitic, and stearic acid. The use of PLE led to a significant decrease in the total extraction time, amount of solvent consumption, and manipulation of samples compared to maceration and ultrasound\u2010assisted extraction methods.<\/jats:p>","DOI":"10.1002\/jssc.200600024","type":"journal-article","created":{"date-parts":[[2006,11,8]],"date-time":"2006-11-08T07:48:55Z","timestamp":1162972135000},"page":"2780-2784","source":"Crossref","is-referenced-by-count":33,"title":["Chemical composition of mate tea leaves (<i>Ilex paraguariensis<\/i>): A study of extraction methods"],"prefix":"10.1002","volume":"29","author":[{"given":"Ros\u00e2ngela","family":"Assis Jacques","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lisiane","family":"dos Santos Freitas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Val\u00e9ria Flores","family":"Peres","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cl\u00e1udio","family":"Dariva","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9 Vladimir","family":"de Oliveira","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elina","family":"Bastos Caram\u00e3o","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2006,12,6]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1350-4177(01)00071-2"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/1615-9314(20020101)25:1\/2<86::AID-JSSC86>3.0.CO;2-7"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2005.07.113"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2005.08.036"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.aca.2004.05.003"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.foodchem.2004.09.037"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.aca.2005.02.028"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2005.06.072"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2004.10.003"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpba.2004.10.038"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpba.2004.10.025"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2004.09.033"},{"key":"e_1_2_1_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jep.2004.10.015"},{"key":"e_1_2_1_15_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00394-003-0399-1"},{"key":"e_1_2_1_16_2","doi-asserted-by":"publisher","DOI":"10.1021\/jf0486141"},{"key":"e_1_2_1_17_2","doi-asserted-by":"publisher","DOI":"10.1021\/jf048158g"},{"key":"e_1_2_1_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ultsonch.2005.11.007"}],"container-title":["Journal of Separation Science"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fjssc.200600024","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/analyticalsciencejournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/jssc.200600024","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,19]],"date-time":"2025-10-19T11:07:47Z","timestamp":1760872067000},"score":1,"resource":{"primary":{"URL":"https:\/\/analyticalsciencejournals.onlinelibrary.wiley.com\/doi\/10.1002\/jssc.200600024"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2006,12]]},"references-count":17,"journal-issue":{"issue":"18","published-print":{"date-parts":[[2006,12]]}},"alternative-id":["10.1002\/jssc.200600024"],"URL":"https:\/\/doi.org\/10.1002\/jssc.200600024","archive":["Portico"],"relation":{},"ISSN":["1615-9306","1615-9314"],"issn-type":[{"value":"1615-9306","type":"print"},{"value":"1615-9314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2006,12]]}}}
