摘要

This study describes the development of a novel, simple and fast analytical method for the detection and quantification of polyphenols in royal jelly products, using an in-house database containing more than 50 compounds. The extraction method consisted of sample dilution, followed by a fast on-line system composed of turbulent flow chromatography (TurboFlow (TM)) coupled to liquid chromatography (LC)-Exactive-Orbitrap analyzer. The total run time was 18 min, including automated extraction, analytical chromatography and re-equilibration. The method was validated obtaining limits of quantification (LOQ) ranging from 10 to 150 mu g/kg. The linearity range was up to 2000 mu g/L and determination coefficients (R-2) were higher than 0.994. Adequate recoveries were obtained at three concentration levels (500, 1000 and 2000 mu g/kg). This method was applied to the analysis of nine samples and the concentration of polyphenols ranged from 14 (apigenin) to 18,936 mu g/kg (ferulic acid).
