Summary

In this work we desribe results of our study on the effect of the composition of solvents used in the extraction process of antiradical compound present in the dried Oreganum vulgare plant in order to obtain information about the antioxidant activity of extracts with potential use in cosmetic products. Various ethanol-water mixtures were used in the research as effective extractants of antiradical compounds. Antiradical activity of the so-obtained dried Oreganum vulgare plant extracts was determined for freshly obtained extracts by spectrophotometric means of determining the total content of phenolic compounds and using the kinetic version of the DPPH• radical assay. It was found that the antiradical activity of the dried Oreganum vulgare plant extracts determined by various methods depends to a large extent on the composition of the solvent used in the extraction process. On the basis of the measurements carried out, it can be concluded that the antiradical activity of the dried Oreganum vulgare plant extracts obtained with the use of various mixtures of ethanol with water is always higher than that found for the extracts obtained using the single solvents.
