Interpretive summary: Polyphenolic compounds are naturally occurring chemicals with a variety of biological activities and numerous potential health benefits. Studies on polyphenols in food samples are important as they generate necessary information on their role and benefits to human health and food quality. This study developed a fast, simple, and cost-effective method for simultaneous determination of multiple polyphenols in juice, tea and coffee samples. The sample preparation was based on a simple “dilute and shoot” approach. The detection was performed using liquid chromatography-tandem mass-spectrometry (LC-MS/MS). The method was successfully applied to the analysis of juice, tea, and coffee samples. The results suggest that the developed method has a promising potential for the analysis of a wide range of polyphenolic compounds. The generated information on occurrence of these chemicals in foods is critical for estimating their content in food, effects on human health and population intake.
