Abstract

This 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.
