Summary

Berries are a valuable source of phenolic compounds. Processed not only on an industrial scale, but also for household purposes (liqueurs, juices), they can play an important role in the prevention of many lifestyle diseases. The paper presents a study on the antioxidant properties of extracts of selected berries (Folin-Ciocalteu method). Seven different berries were tested in three solvent systems. It has been shown that the type of solvent and the extraction time significantly affect the content of the tested compounds in the analysed solutions.
