Development of a simultaneous analytical method for the dietary exposure determination of β-Carboline alkaloids in foods.

As β-carboline (βC) alkaloids, posing potential health risks, are present in a wide variety of foods, determining the exposure degrees of food to these alkaloids from dietary activity is key to ensuring food safety. Here, we developed a rapid and sensitive simultaneous analytical method for six βC alkaloids in food. We optimized the buffered QuEChERS method, which includes a clean-up process through dispersive solid phase extraction, to extract the target compounds from food matrices; then, these compounds were detected via liquid chromatography-tandem mass spectrometry.
