Results of experimental work on antiradical activity of extracts form sage and rosemary are presented. Antiradical activity was determined based on kinetics of the quenching of DPPH^• radical in the aqueoussolutions of resulting extracts. It was found that the experimentally observed antiradical activity mainly depends on extrahent used and it decreases in the following order: hexane > ethyl acetate > water > methanol > acetone.
