Abstract

Relative retention times and detector responses of the trimethylsilyl ether and oxime derivatives of the components of electrochemically reduced glucose syrups and commercial sorbitol samples are reported. d-Glucose, 2-deoxy-d-glucose, d-glucitol and 2-deoxy-d-glucitol each gave a single main peak on Dexsil 300 stationary phase a second peak of d-glucose was about one quarter the height of the main peak. Amounts of 0.13-13 μg of all four components in the presence of each other, even in ratios of 1:100, have been measured with relative standard deviations of 2.5-5.3%. The amount of 2-deoxy-d-glucitol in commercial sorbitols varied from >0.1 to 0.8% (w/w).
