Abstract

Pectic polysaccharides were isolated from the husks of field bean (Dolichos lablab), cowpea (Vigna sinensis) and pea (Pisum sativum), using HCl (pH 2.0) and 0.5% EDTA as extractants at 70C, in yields varying from 1.43 to 5.37%. Pectic polysaccharides obtained by 0.5% EDTA extraction were more viscous and gave a higher yield than acid-extracted ones. Acetyl and methoxyl groups had no effect on viscosities of the polysaccharides. Compositional analysis indicated the presence of mainly arabinose, rhamnose and xylose in addition to high amounts of uronic acid.
