This document describes a procedure for the determination of the citrinin content in food (cereals, red yeast rice (RYR)), herbs and food supplements by liquid chromatography tandem mass spectrometry (LC MS\/MS). This method has been validated for citrinin in red yeast rice and in the formulated food supplements in the range of 2,5 \u00b5g\/kg to 3000 \u00b5g\/kg and in wheat flour in the range of 2,5 \u00b5g\/kg to 100 \u00b5g\/kg. Laboratory experiences have shown that this method is also applicable to white rice, herbs such as a powder of ginkgo biloba leaves and the formulated food supplements in the range of 2,5 \u00b5g\/kg to 50 \u00b5g\/kg.<\/p>\n
