| Resumo: | Address in this article the development and validation of analytical technique for quantification of caffeine by high performance liquid chromatography (HPLC-UV). The study aimed to determine the caffeine content and check the levels in decaffeinated coffees are within the standards determined by regulatory agencies. The chromatographic analysis was performed on a column C-18 reverse phase Phenomenex®, Gemini, mobile phase water/acetonitrile. The samples were extracted and delivered in acetonitrile and analyzed as compared to caffeine in chloroform standard (1 mg.ml-1). The given technique presented the best conditions of chromatographic separation. The results provided by the validation demonstrated technique with very good linearity, precision and accuracy, In addition to simple, rapid implementation methodology, with lower costs and satisfactory results, reduced time without compromising the trustworthiness of the analysis. |
