Abstract:
Plants are an important source of secondary metabolites, such as substances that have a beneficial biological effect on the health of humans and they are irreplaceable in the modern medicine. They may operate in prevention and in the treatment of civilization diseases. In terms of content substances, the phenolic come to fore, especially polyphenols, which have been related to a number of overview studies due to their wide distribution and high concentration in plants. They also represent an important part of substances with redox effects present in the human diet and have an important role fo

Secondary metabolism of plants, building on primary metabolism, is a source of many substances - called secondary metabolites. These substances show a diverse range of effects that are currently used in pharmacy and medicine. A large number of secondary metabolites exhibit, for example, anti-inflammatory activity.
