Abstract
The present paper is part of an ongoing study undertaken to evaluate the effect of hot-water extraction on sugar maple (Acer saccharum), for extending the scope of ESF biorefinery. The final objective is to assess the contribution of hot-water extracted non-carbohydrate-based organic compounds to generate a stream of platform chemicals. The hot-water extracts (HWEs) were subjected to ultrafiltration to remove the insoluble solids and the clear permeate was extracted with organic solvents, derivatized and analyzed by GC/MS. The organic extracts of the HWEs were composed mainly of phenolics. These compounds were compared to the extractives obtained from native sugar maple wood. Our results indicate that the aromatic compounds present in the organic extracts of HWE may be extractive-based or products of lignin acidolysis generated primarily by cleavage of the ?-O-4 linkages.
