This study was conducted to determine the content of carbohydrates and mucilage inroots and leaflets of different Astragalus species for the first time from Iran. The content ofreducing sugars, oligosaccharides and polysaccharides in roots of the species were determinedspectrophoto-metrically. The content and sugar composition of the mucilages in leaflets wasdetermined by gravimetry and gas-liquid chromatography, respectively. According to theresults of this research, the content of sugars in roots and mucilage in leaflets depends onthe factors such as the species and geographical location of the plants. Reducing sugars,oligosaccharides and polysaccharides content in roots of the species varied from 0.11-0.90,2.21-7.27 and 1.3-7.33% dry weight, respectively. The mucilage content in leaflets of differentspecies varied from 5.32 to 19.24% dry weight.
