[Study of galactoglucomannans from the seed of Cercis canadensis L].

Galactoglucomannans were isolated by selective precipitation from aqueous and alkaline extracts of endosperm and hulls of Cercis canadensis, a member of the family Fabaceae. Their monosaccharide composition (Man: Gal: Glu) was as follows: 10.4: 0.

[Galactomannan from ambiguous Crazyweed (Oxytropis ambigua (Pall) DC)].

A galactomannan with a molecular weight of 735 kDa was first isolated and purified from seeds of ambiguous crazyweed Oxytropis ambigua (Pall) DC. (family Leguminosae) with a yield of 3.6%.

[Composition and structure of a galactomannan macromolecules from seeds of Astragalus lehmannianus Bunge].

The composition and structure of a galactomannan from seeds of Astragalus lehmannianus, an endemic legume species, is reported for the first time. The purified galactomannan (yield, 4.8%) contained 55% D-mannose and 45% D-galactose and had a molecular weight of 997.
