Forchlorfenuron(1-(2-chloro-4-pyridyl)-3-phenylurea) is a plant growth regulator, which mainly be used to increase the size and weight of kiwifruit. The standards of forchlorfenuron metabolites were obtained by chemosynthesis and forchlorfenuron and its metabolites(4-hydroxyphenyl-forchlorfenuron, 3-hydroxyphenyl-forchlorfenuron, forchlorfenuron-4-O-β-D-glucoside and forchlorfenuron-3-O-β-Dglucoside) in kiwifruit were simultaneously determined by LC-MS/MS with ESI+ under the mode of multiple reaction monito...
