Summary: | The invention discloses a method for detecting desmedipham and phenmedipham in strawberries, which adopts a high performance liquid chromatography-mass spectrometry method for detection, and in the strawberries, the average recovery rate of desmedipham is 88-104%, and the relative standard deviation (RSD) is 1-3%; the average recovery rate of the phenmedipham is 88%-104%, and the relative standarddeviation (RSD) is 2%-7%. The invention provides a reliable detection method for researching the change condition of the residual quantity of the strawberries after the two medicines are applied, andmeanwhile, the blank that desmedipham and phenmedipham in a strawberry matrix cannot be simultaneously detected by an existing method is filled up.
本发明公开了一种草莓中甜菜安、甜菜宁的检测方法,采用高效液相色谱-质谱联用法检测,在草莓中,甜菜安的平均回收率为88%~104%,相对标准偏差(RSD)为1%~3%;甜菜宁平均回收率为88%~104%,相对标准偏差(RSD)为2%~7%。本发明为研究草莓施用了上述2种药物后残留量的变化情况提供了一种可靠的检测方法,同时填补了现有方法不能同时检测草莓基质中甜菜安、甜菜宁的空白。 |
