Abstract
The genus Astragalus is generally considered one of the largest genera of vascular plants, with an estimated 2500-3000 species. Iran is one of the main centers of Astragalus dispersal. In this research, a variety of phenolic compounds and saccharide content were evaluated in the roots of ten Astragalus species. The high content of total oligosaccharides and polysaccharides was observed in A. siliqusus and A. caraganae, respectively. The largest content of phenolics and o-diphenols was detected in A. glochideus. Roots of A. paralurges, A. siliqusus, and A. caraganae had the highest level of phenolic acids, flavonoids, and condensed tannin, respectively. Gas-liquid chromatography (GLC) analysis of phenolic compounds revealed that syringic acid, p-coumaric acid, and caffeic acid were the dominant phenolic acids in roots of the most species of Astragalus. In conclusion, this result revealed that Astragalus species used in this research have been known as an important potential source of antioxidative compounds and can be used in the food and pharmaceutical industry.
