Pretreatment method of forchlorfenuron residues in loquat by HPLC analysis by YANG Chunping, LI Zhaojun, NING Hong, CHEN Huabao, GONG Guoshu, YANG Jizhi, ZHANG Min

“…Therefore, residue detection of forchlorfenuron in fruits and vegetables is imperative.High-performance liquid chromatography (HPLC) analysis is a common detection method. The suitable conditions for the extraction and purification of sample play an important role prior to HPLC analysis.In this study, the extraction efficiency of forchlorfenuron residues in loquat was compared using matrix dispersive solid phase extraction and QuEChERS (quick, easy, cheap, effective, rugged, safe).The results showed that QuEChERS was a more suitable pretreatment method for the determination of forchlorfenuron residues in loquat, because it had obviously higher average recoveries than the matrix dispersive solid phase extraction. …”
