Rezumat: The aim of this study was the development and validation of a new method for glucose analysis obtained from woody biomass by steam-explosion and enzymatic hydrolysis. Quantification of glucose was made by liquid-liquid extraction, oximation and silylation and, finally, analysis by gas chromatography-mass spectrometry (GC-MS). Glucose derivatives obtained were identified by their GC retention time and the corresponding MS fragmentation. BSTFA was used as derivatization reagent to prepare the trimethylsilyl derivatives of glucose. Keywords: glucose, wood carbohydrates, derivatization, GC-MS |
