Biological Activities
Compounds
Astragalus lehmannianus is an endemic legume species that has been found to contain a specific type of galactomannan within its seeds. This complex macromolecule is primarily composed of D-mannose and D-galactose, which together form its unique structural framework. Detailed chemical analysis reveals that the molecule's main chain consists of mannose residues that are frequently substituted with Alpha-D-Galactopyranose. Specifically, the purified galactomannan was found to be composed of 55% D-mannose and 45% D-galactose. These findings provide significant insight into the intricate carbohydrate composition of this particular plant species.
