| Abstract: | Super-high performance liquid chromatography-mass spectrum in series(UPLC-MS/MS) method was developed for the determination of glyphosate in sugar cane.Glyphosate in sugar cane was separated by ASE.The extracts were derivated with FMOC-Cl,and the glyphosate content was determined by UPLC-MS/MS.The limit of detection(LOD) for glyphosate was 0.05mg/kg.The linear range was 0.01-1 μg/mL with correlation coefficient above 0.999.The mean recovery was between 86.5 % and 100.6%.This method can be applied for the determination of glyphosate in sugar cane for its high sensitivity and high selectivity |
