Euacalyptus is part of the national economy. This is a natural source that provides pulp for papermaking, coal for the steel industry and bioactive compounds used in various medical and industrial areas. The essential oil extracted from leaves is an important product obtained from Eucalyptus. This work evaluated essential oil extracted from leaves of Eucalyptus resistant and susceptible to Glycaspis brimblecombei using thermal tools. Samples of essential oils were extracted from crushed leaves of E. pellita (resistant) and E. camaldulenses (susceptible) by Clevenger method. The oils were analyzed by physicochemical characterization, thermogravimetry and differential thermal simultaneous analysis (TGA-DTA) and differential scanning calorimetry (DSC). The TGA curves of the essential oil from E. camaldulensis and commercial showed similarity and show that the major constituent can be 1,8-cineole. However, the TGA curves of the E. pellita essential oil has different pattern. In DSC, changing the endothermic peak of the commercial oil indicates the presence of other components or additives. The results indicate that these Eucalyptus essential oils had different chemical composition and the 1,8- cineole can be the reason of resistance and susceptibility to G. brimblecombei attack. Further studies will be performed to characterize these samples. |

Abandonment of planting of Gossypium barbadense has endangered its existence. The objective was to determine the characteristicof the maintenance of Gossypium barbadense in the Central-West Region of Brazil, with the aim to foster the conservation of the species. Expeditions were conducted in 2014-2015 in Southeast Goiás, where cotton collection has not been reported before. Data from previous collections in Goiás, Mato Grosso, Mato Grosso do Sul and Distrito Federal available in Albrana database were considered this study. In the Central-West Region of Brazil, 466 accesses of G. barbadense were recorded, found most frequently in backyards (91.4%), but also spontaneous plants (7.5%), farm boundary (0.8%) and commercial farming (0.2%) have also been found. The main use indicated by VDU was as medicinal plant (0.66), therefore this is the main reason for in situ preservation. However, this cultural habit has been abandoned, causing uncertainty about the continuity of preservation. There was presence of lint almost only in seeds of plants of the variety brasiliense. The most common fiber color was white, not cream color, suggesting that plants are derived from commercial cultivars used in the past. Hence, until 2015, the conservation relies on single plants almost exclusively in backyards for medicinal use, and there are no crops of this type of cotton for commercial purpose. The exploitation of the possible use both of the fiber as a medicinal plant would foster ex situ and in situ preservation of this important genetic resource.
