Leaves of wild-growing species Astragalus onobrychis L. subsp. chlorocarpus (Griseb.) S. Kozuharov et D.K. Pavlova were collected during the different stages of growth and analyzed for iron (Fe), copper (Cu), zinc (Zn), manganese (Mn), soluble proteins, reduced glutathione (GSH), total flavonoid and total carotenoid contents. Iron, copper and manganese have shown similar seasonal patterns of increase of metal content in leaves during the vegetative period. The highest content values of the examined elements occured in the seed forming stage, except zinc. The highest value of this element was recorded in the initial stage of vegetation. Antioxidant compounds have the highest values in the blooming stage of vegetation. The results from the present study suggest that researched plant species represent a good source of trace elements and antioxidant compounds.
