چکیده
Da casca do tronco de Hymenaea courbaril var. altissima (Ducke) foi isolado um novo entclerodano na forma de éster metílico, após esterificação com diazometano, o (-)-(5R,8S,9S,10R)clerod-3-en-15-oato de metila. Foram isolados também dois ent-labdanos conhecidos: o (-)-copalato de metila e (-)-eperuato de metila. Do extrato AcOEt do epicarpo foi isolado, após esterificação com diazometano, o (-)-zanzibarato de metila. As estruturas dos compostos foram elucidadas com base na análise de dados espectroscópicos.

متن کاملStructure and rheological properties of a xyloglucan extracted from Hymenaea courbaril var. courbaril seeds.
Hymenaea courbaril var courbaril seed xyloglucan was efficiently extracted with 0.1M NaCl, followed by ethanol precipitation (yield=72±5% w/w). Its amorphous structure was identified by the pattern of X-ray diffraction. The monosaccharide composition was determined by GC/MS analysis of the alditol acetates and showed the occurrence of glucose:xylose:galactose:arabinose (40:34:20:6). One-(1D) an...

Background: The biotechnological potential of medicinal plants from Brazilian Caatinga and the Atlantic Forest has not been extensively studied. Thus, screening programs are important in prospecting for compounds for developing new drugs. The purpose of this study was to determine the chemical composition and to evaluate the anti-Candida activity of essential oils from leaves of Hymenaea courba...
متن کاملFirst isolation of Cryptococcus neoformans genotype VNI MAT-alpha from wood inside hollow trunks of Hymenaea courbaril.
Cryptococcal infection is transmitted by the inhalation of Cryptococcus spp. propagules. Information about the Cryptococcus species inhabiting plants might be clinically relevant due to the epidemiological role of these habitats as possible sources of human infection. The aim of this study was to increase the knowledge about the environmental occurrence of cryptococcosis agents. Hollow tree veg...
متن کاملLEAF LIFE SPAN AND NITROGEN CONTENT IN SEMIDECIDUOUS FOREST TREE SPECIES (Croton priscus AND Hymenaea courbaril)
In comparison to deciduous species, evergreen plants have lower leaf nutrient contents and higher leaf life span, important mechanisms for nutrient economy, allowing the colonization of low fertility soils. Strategies to conserve nitrogen in two semideciduous tropical forest tree species, with different leaf life spans were analyzed. The hypothesis was the fact that the two species would presen...
