ABSTRACT

Flavonoids belong to the most widespread natural compounds [1-10]. Their sources are mainly higher plants. They also occur in algae, lichens, mosses, fungi, ferns and some representatives of insects and microorganisms. They are found in roots, wood, leaves, flowers, fruits. These compounds are present in various cell organelles of plants. They are revealed in a broad colour palette of the flora and are represented in a whole range of products of plant raw material processing (juices, wine, oil and extracts).
