- 47 Downloads
1. A polysaccharide has been isolated from the leaves ofPlantage major L. and its monosaccharide composition has been studied.
2. It has been established that the polysaccharide investigated contains D-galacturonic acid, D-galactose, D-glucose, D-xylose, L-rhamnose, L-arabinose, a partially methylated galactose, and two unidentified monosaccharides.
3. The high content of galacturonic residues (68%) in the polysaccharide enables it to be classified as a pectin.
KeywordsPolysaccharide Xylose Monosaccharide Arabinose Rhamnose
