The objective of this paper was to determine the contents of some selected biologically active compounds in the extracts produced of dried apricots and their antioxidant properties. The value of dry mass was determined in dried fruit whereas in the extracts - the contents of: polyphenols, catechins, vitamin C, and carotenoids. Antioxidant properties of extracts were investigated using DPPH radicals and ABTS cation radicals, the ability of those extracts to chelate iron ions was also determined. Based on the results obtained, it was concluded that dried apricots were a valuable, but still underestimated source of food compounds appearing important for human organisms. All the extracts showed strong antioxidant properties towards synthetic radicals as well as the ability to chelate iron ions
