MUCILAGE CONTENT AND ITS SUGAR COMPOSITION IN ASTRAGALUS SPECIES FROM IRAN H. EBRAHlMZADEH, V. NIKNAM AND A.A. MAASSOUMI*
Abstract: Mucilage content and its sugar composition
in leaflets of 15 species of Astragalus from Iran were examined. The mucilage
content of different species varied from 3.44 to 23.56% dry weight. Mucilage content
in some of the species of this genus is comparable with that of the richest sources
of mucilage. The mucilages obtained from different species, all showed the presence
of glucose, galactose, arabinose, xylose, fucose and rhamnose but in different
amounts. In mucilages of 1.2 species glucose was the major monosaccharide and
in 3 species galactose was the main constituent. The uronic acids were detected
in 12 of the 15 species.
