Studies of seed mucilages. V. Examination of a polysaccharide extracted from the seeds of Plantago ovata Forsk by hot water

Studies of seed mucilages. V. Examination of a polysaccharide extracted from the seeds of Plantago ovata Forsk by hot water

Jour Chem Soc [london] (2): 528-534

Extraction of these seeds with hot water, after exhaustive extraction with cold water, yielded a polysaccharide fraction (PII, equiv., ca. 4000; uronic anhydride, ca. 3%; pentosan, ca. 90%, methylpentosan, nil). Hydrolysis of PII gave D-xylose (80%), L-arabinose (14%), D-galactose (a trace), an aldobiuronic acid (ca. 0.3%) and an insoluble residue (ca. 3%). Acetylation, deacetylation and methylation, and fractional precipitation gave products A (63%), B (32%), and C (5%). Methanolysis and hydrolysis of A gave trimethyl D-xylopyranose (8 parts), trimethyl L-arabofuranose (3 parts), tetramethyl D-galactopyranose (ca. 0.3%), a 2,6-dimethyl hexose (1 part), 2,4-dimethyl D-xylopyranose (4 parts), 3-methyl D-xylopyranose (8 parts), and D-xylopyranose (1 part).
