Determination of Luteoskyrin in Rice Wine by High-Performance Liquid Chromatography-Ion Trap Tandem Mass Spectrometry

摘要

A method for luteoskyrin in Chinese rice wine was developed using high-performance liquid chromatography-ion trap tandem mass spectrometry. The detection limit of luteoskyrin was 0.10 mu g/kg. The recovery values of luteoskyrin in fortified Chinese rice wine were between 85.7% and 88.9% at levels between 0.5 mu g/kg and 100 mu g/kg (R>0.999). The relative standard deviations were in the range of 1.10% to 3.20%. The method achieved rapid and accurate determination of luteoskyrin in Chinese rice wine while meeting minimum residue measurement requirements.
