Perfil químico do óleo volátil das folhas de Erythroxylum deciduum A. St.-Hil. (Erythroxylaceae), coletadas em Goiânia, Goiás

Abstract

The Erythroxylum (Erythroxylaceae) genus has about 130 species, which can be found in forest environments and cerrado. Studies with Erythroxylum species led to the isolation of secondary metabolites such as flavonóides, alkaloids, tannins, terpenes and phenylpropanoids that exhibit anti-oxidant activity, anti-carcinogenic, anti-inflammatory activity among others to be operated with pharmaceutical purposes. In order to contribute to the chemical elucidation of Erythroxylum genus, this research aimed to evaluate the composition of the essential oil from the leaves of E. deciduum A. St.-Hil. The botanical material was collected in the peri-urban area of the city of Goiânia, Goiás, Brazil, it was identified and had a voucher specimen deposited in the Herbarium of the State University of Goiás. The essential oil extraction was performed by hydrodistillation adapted by Clevenger. The essential oil chemical composition was determined by gas chromatography-mass spectrometry (GC/ MS). The species studied showed as major components: himachalol (3.49%), sandaracopimarinal (4.87%), ethyl 8cedren-13-ol (5.65%) and ternina (6.37%) whose description on the literature, points to the antimicrobial and allelopathic activity. Thus, These volatile components may be viable in obtaining bioproducts or as prototypes in the synthesis of compounds of pharmacotherapeutic, food and agricultural interest.
