The content of total phenolic in roots, leaflets and seeds of a number ofAstragalus species from Iran was examined. Phenolic content of the aqueousand methanolic extracts of the species were determined spectrophotometricalIy.Phenolic content depend on factors such as the species, geographical locationof the plants and the organs. Moreover, the content of phenolic depends onthe extraction solvents. Phenolic content in roots and leaflets of the speciesusing aqueous extracts varied from 0.13-0.80 and 0.63-5.16% dry weight,respectively while using methanolic extracts ranged from 0.25-0.95 and 0.52-3.75% dry weight, respectively. Generally, the content of phenolic in leafletswas higher than that of the roots and seeds. In this paper the content of thephenolic in various species of Astragalus is reported for the first time.
