Resumo: This study was done to evaluate the influence of drying air temperature on the chemical composition of the essential oil of Melaleuca alternifólia Cheel. Three samples were taken at random from each treatment which were analyzed still fresh, determining the moisture content and chemical composition of the essential oil.The plants were chopped and placed in a fixed-bed dryer and dried with air temperature of 40, 50, 60, 70 and 80 °C. The identification of compounds was done using gas chromatography coupled to mass spectrometry. The major components of essential oil of melaleuca subjected to drying air temperatures of 40, 50, 60, 70 and 80 ° C were within the ISO Standard 4730, which classifies plant as medicinal or not.There was an increase in the levels of terpinen-4-ol and ?-terpineol and decrease of ?-pinene compared to the control.

Foram tomadas aleatoriamente três amostras de cada tratamento que foram analisadas ainda frescas, avaliando o teor de água e os constituintes químicos. Para a realização dos testes de secagem foram utilizadas amostras da planta triturada, utilizando um secador de leito fixo. As temperaturas do ar de secagem foram 40, 50, 60, 70 e 80°C. A identificação dos compostos foi feita empregando-se cromatografia em fase gasosa acoplada à espectrometria de massas. Os componentes majoritários do óleo essencial de melaleuca submetidos às temperaturas do ar de secagem de 40, 50, 60, 70 e 80 °C atendem dentro Padrão ISO 4730, que classifica a planta como medicinal ou não. Foi observado também o aumento no teor de terpinen-4-ol e ?-terpineol, e redução do teor de ?-pinene comparado com a testemunha.Universidade Federal de Viçosa - UFV2012-03-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/20410.13083/reveng.v20i1.224Engineering in Agriculture; Vol. 20 No. 1 (2012); 5-11Revista Engenharia na Agricultura - REVENG; v. 20 n. 1 (2012); 5-112175-68131414-398410.13083/reveng.v20i1reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/204/165Lemos, Diana Rodrigues HerinqueMelo, Evandro de CastroRocha, Ronicely PereiraBarbosa, Luiz Cláudio de AlmeidaPinheiro, Antonio Lelisinfo:eu-repo/semantics/openAccess2023-01-19T13:00:52Zoai:ojs.periodicos.ufv.br:article/204Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:00:52Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
