Method for detecting residual quantity of bicyclopyrone and metabolite of bicyclopyrone in plant-derived product

The invention discloses a method for detecting the residual quantity of bicyclopyrone and metabolite thereof in a plant-derived product. The method comprises the following steps: extracting an extracting solution from the plant-derived product; performing impurity removal and purification on the extracting solution; and carrying out mass spectrometric analysis on the impurity-removed and purified extracting solution to obtain the residual quantity of bicyclopyrone and metabolite thereof in the plant-derived product. The invention establishes a method for detecting the residues of the bicyclopyrone and the metabolite thereof in the plant-derived product, and qualitative screening and synchronous quantification of the bicyclopyrone and the metabolite thereof are realized for the first time; the method is simple to operate, high in sensitivity and good in accuracy. 本申请公开了一种检测植物源产品中氟吡草酮及其代谢物残留量的方法，其包括：从植物源产品中提取提取液；对提取液进行除杂净化；对除杂净化后的提取液进行质谱分析，得到植物源产品中氟吡草酮及其代谢物的残留量。本申请建立了对植物源性产品中氟吡草酮及其代谢物残留的检测方法，首次实现对氟吡草酮及其代谢物的定性筛查
