The influence of petroleum ether, ethyl acetate and water extracts of elecampane (lnula helenium L) on the transformation of the stable 1,1-diphenyl-2-pycrylhydrazil (DPPH) radicals has been investigated by ESR spectroscopy. Using the phytochemist "screening" test a qualitative analysis of extracts has been made. On the basis of the obtained results it can be concluded that the investigated elecampane extracts have the antioxidative activity due to the hydrogen donor ability of the constituent biomolecules such as tannins, terpenes, polyphenols, etc. The following order of antioxidative activity has been established: ethyl acetate > petroleum ether > water extracts. Also, the investigation showed that the antioxidative activity increased with increasing concentration of all the extracts
