RESUMO
Os óleos de frutos estão sendo estudados por seu potencial na indústria de alimentos e também para aumento do consumo de ácidos graxos monos e poli-insaturados. Este estudo objetivou determinar as constantes físico-químicas, composição centesimal, identificar e quantificar os principais ácidos graxos presentes na fração lipídica da polpa e da amêndoa dos frutos de guarirova, espécie Syagrus oleracea (Mart.) Becc. Foi realizada a caracterização físico-química dos óleos, composição de ácidos graxos e índices de qualidade nutricional. O óleo da amêndoa possui maior concentração de ácidos graxos saturados (89,2%), sendo representado principalmente pelo ácido láurico (48,34%). A polpa apresentou ácidos graxos monoinsaturados (24,84%) e poli-insaturados (33,25%), com maior percentual de ômega-6 (31,94%) e ômega-9 (19,15%); e menor de ômega-3 (1,31%).
The oils of fruits are being studied for its potential in the food industry and also to increase the consumption of mono and polyunsaturated fatty acids. This study aimed to determine the physio-chemical constants, chemical composition and identify and quantify the major fatty acids present in the lipid fraction of pulp and kernel of the fruits of guarirova, species Syagrus oleracea (Mart.) Becc. It was performed the physicochemical characterization of oils, fatty acid composition and nutritional quality indexes. Almond oil has the highest concentration of saturated fatty acids (89,2%), represented mainly by lauric acid (48,34%). The pulp showed monounsaturated (24,84%) and polyunsaturated fatty acids (33,25%), with higher percentage of omega-6 (31,94%) and omega-9 (19,15%) and lower omega-3 (1,31%).
RESUMO
A method for sample preparation and analysis by high performance liquid chromatography with UV detection (HPLC-UV) was developed for analysis of jatrophone in "cachaça" prepared with Jatropha elliptica, administered orally, employed in Brazil for the treatment of venomous snake bites. The linearity, accuracy, precision of the procedure was evaluated. Analytical curve for jatrophone was linear in the range of 16.24-81.20 microg ml(-1). The recovery of the jatrophone in the samples analyzed was 98.99-99.89%. The percent coefficient of variation for the quantitative analysis of the "cachaça" in the analyses was under 2%.
