dc.description.abstractThis study aimed to evaluate the influence of drying air temperature on the content and chemical composition of essential oil extracted from guaco. Six drying treatments were used: ambient air and heated air at 40, 50, 60, 70 and 80o C. The essential oil contents, after drying, were compared with the values obtained from the fresh plant (control). The essential oil extraction was performed by hydrodistillation. From the results obtained, it could be concluded that the temperature of the drying air at 50o C provided the best results for the extraction of essential oil in guaco leaves, despite the fact that the chromatographic profile of the oil showed alterations in comparison with that obtained from the fresh plant.en
dc.description.abstractEste estudo teve como objetivo avaliar a influência da temperatura do ar de secagem sobre o teor e composição química do óleo essencial extraído de guaco. Seis tratamentos de secagem foram utilizados: ar ambiente e ar aquecido a 40, 50, 60, 70 e 80º C. O conteúdo de óleo essencial, após secagem, foi comparado com os valores obtidos a partir da planta fresca (testemunha). A extração do óleo essencial foi realizada por hidrodestilação. A partir dos resultados obtidos, podese concluir que a temperatura do ar de secagem a 50º C proporcionaram os melhores resultados para a extração do óleo essencial em folhas de guaco, apesar de que os perfis cromatográficos do óleo mostraram alterações em comparação com o obtido da planta fresca.pt-BR
