| Resumo: | Essential oils (O.Es), also known as volatile oils, ethereal oils or simply essential oils, are defined by the ISO-International Organization for Standardization as products obtained from different parts of plants. The umbu tree, Spondias tuberosa, belonging to the Anacardiaceae family, originating from the less rainy regions of the North and Northeast of Brazil, has great regional importance, being sold fresh or in pulp, serving as a source of income, the different structures of the plant are used in folk medicine, giving the genus Spondias substances with medicinal properties. In view of the above and due to little existing research related to the essential oil of the genus Spondias, especially the species Spondias tuberosa, this study aims to evaluate the yield of O.Es from Spondias tuberosa leaves using different methodologies subjected to micro-extraction. waves, as well as physically analyzing the O.Es obtained. The highest yield of essential oil was from dried umbuzeiro leaves with a total percentage of 0.36% yield. The O.Es had a yellowish color with a strong and unpleasant smell. The refractive index obtained was 1.503 for the O.Es of the dry leaf and 1.506 for the oil of the green leaf. It is possible to conclude that the yield of dry leaf essential oil obtained is considered good, where for every 1 kg of dry plant material 3.66 ml of essential oil is obtained. |
