Isolation and structural characterization of lignin-carbohydrate complexes from sisal and abaca fibers

Lignin carbohydrate complexes (LCC) were isolated from sisal and abaca. Two LCC fractions, namely GL and XL, were isolated in a quantitative manner. GL fractions were enriched in glucans and depleted in lignin whereas XL fractions were depleted in glucans but were enriched in xylans and lignin. The...
