S.* Constituintes químicos de frações não-polares obtidas de Cnidoscolus quercifolius Polh (Euphorbiaceae), uma planta medicinal brasileira nativa da Caatinga Abstract: Cnidoscolus quercifolius Pohl is a Brazilian medicinal plant from Caatinga biome and possesses several pharmacological properties. In this paper, we describe the identification of compounds from non-polar fractions of the leaves (Hex-Le) and stem-barks (Hex-Sb) from C. quercifolius. Chemical analysis were performed by GC-MS approach. Chemical constituents were identified based on spectral data obtained and by comparison with literature data. Fragmentation profile of the main compounds was proposed and presented in this paper. Hydrocarbons (46.84%), triterpenes (32.60%) and carotenoid derivatives (0.83%) were considered the major constituent of Hex-Le. In contrast, hydrocarbons (41.89%), diterpenes (12.83%) and triterpenes (7.0%) were found in Hex-Sb. Four diterpenes (dehydroabietane, sandaracopimaradiene, kaur-16-ene and 13-methyl-17-norkaur-15-ene) and one triterpene (diploptene) are reported for the first time in Cnidoscolus. Resumo: Cnidoscolus quercifolius Pohl é uma planta medicinal do Brasil, nativa do bioma Caatinga, que apresenta diversas propriedades farmacológicas. Nesse estudo, nós descrevemos a identificação de compostos de frações não-polares obtidas das folhas (Hex-Le) e cascas do caule (Hex-Sb) da espécie. As análises químicas foram realizadas por CG-EM. Os constituintes químicos foram identificados com base nos dados espectrais obtidos e por comparação com os dados da literatura. O perfil de fragmentação dos principais compostos identificados também foi proposto e é igualmente apresentado nesse trabalho. Hidrocarbonetos (46,84%), triterpenos (32,60%) e derivados de carotenoides (0,83%) foram considerados os constituintes majoritários de Hex-Le. ...
