Abstract
Polysaccharides extracted from seeds of Libyan dates with hot ethanol 80% ( FI) and 0.1 M phosphate solution (FII) were fractionated and purified by io n-exchange and gel-filtration chromatography. According to methylation and hydrolysis analysis, the main chains of FI and FII consisted of (1 -->4)- l inked glucomannan; only traces of branched sugar residues were detected. Th is is the first report on the isolation of glucomannan from date seeds.
