摘要

The research aims to indicate which of the structural elements of monoterpenes are responsible for their antioxidant activity. The activity was determined spectrophotometrically with the use of the DPPH~· assay. It has been shown that π bonds are responsible for the chain-breaking antioxidant activity of monoterpenes. It has been proved, for the first time, that blocking of conjugated double bonds leads to a decrease of the antioxidant activity of monoterpenes. A probable reaction mechanism between monoterpenes and DPPH* has been proposed. It has been indicated that the antioxidant activity of monoterpenes strongly depends on the polarity of solvent used in the experiments. The presented results may stimulate additional research in the field of terpenoid antioxidants.
