Cell Wall of Melampyrum lineare Seed: Carbohydrate Components.

Extraction with alkali of cell wall material from the seed of Melampyrum lineare leaves a residue (62.7 percent) which on hydrolysis yields over 70 percent mannose. Hydrolysis of the alkali-soluble hemicellulose fraction of the cell wall also yields largely mannose. In contrast, cell wall isolated from Melampyrum stem contains over 95 percent of glucose residues in the alkaliinsoluble fraction, and mostly xylose residues in the hemicellulose.
