超高效液相色谱-串联质谱法检测果蔬中植物生长调节剂及残留规律研究
Residue Determination of Plant Growth Regulators in Fruits and Vegetables by UPLC-MS and Studied the Regulation of Plant Growth Regulators
摘要
Abstract
In recent years,the detection of plant growth regulators has received much attention.To establish an analytical method for the determination of 11 kinds of plant growth regulators in fruits and vegetables by ultra performance liquid chromatography-tandem mass spectrometry(UPLC-MS).Each component had a good linear relationship in a certain range,R2＞0.99.The limits of detection of the method were in ranged of 0.5-5 μg/kg.The average recoveries were 80.8%-117.0%.Through the study of the residue pattern of chlorpyrifos in kiwifruit,it was found that chlorpyrifos degrades rapidly in the first two and a half months of fruit ripening,and was basically completely degraded by the first month before ripening.This method could efficiently detect plant growth regulators,and provide technical support for risk monitoring and evaluation of plant growth regulators in vegetables and fruits.关键词
