dc.description.abstract | A novel home-made hybrid detection system was designed for simultaneous determination of caffeine (CAF), dipyrone (DIP) and ergotamine (ERG) in pharmaceutical preparations. Thus, ERG was determined by a fluorimetric signal and PLS-1 method for resolving DIP and CAF UV-V spectral data was used. The calibration curve for ERG was linear over the range 2.5 - 10 mg L-1. The calibration set consisted of 18 mixtures with 0.5 to 4 mg L-1 for CAF, 5 to 20 mg L-1 for DIP and 2.5 and 10 mg L-1 for ERG. Sample preparation prior to analysis was not required. A recovery study with the real samples was carried out and the obtained results were highly satisfactory. | |
dc.description.abstract | Um novo sistema híbrido para detecção simultânea de cafeína (CAF), dipirona (DIP) e de ergotamina (ERG) foi desenvolvido para teste de preparações farmaceuticas. ERG foi determinada por um sinal fluorimétrico, enquanto para CAF e DIP foi utilizado o método PLS-1 para resolução de dados espectrométricos de UV-Vis. A curva de calibração da ERG foi linear na faixa de 2.5 10 mg L-1. O conjunto de calibrações constiui-se de 18 soluções com 0.5 a 4 mg L-1de CAF, 5 a 20 mg L-1 de DIP e de 2.5 e 10 mg L-1 de ERG. Não foi necessária a prepração de amostras anterior à análise. Foram realizados estudos de recuperação com amostras reais obtendo-se resultados altamente satisfatórios | |
