Abstract
A sensitive and reliable analytical method for determining furosine in hair has been developed using liquid chromatography-tandem mass spect rometry, Fructose-N-alpha-formyl-d(4)-DL-lysine was synthesized and us ed as an internal standard, By the present method, glycated lysine lev els in hair could be determined as fructose-lysine in only 0.1 mg of h air sample, ranging from 35.1-72.6 ng/mg hair among five healthy volun teers, which corresponded to 0.0635-0.153% of the total lysine content s in hair determined by amino acid analysis.
