The content of selected biologically active substances in wild plants traditionally used as vegetables
ŠUSTEROVÁ, Simona
A balanced diet should contain, in addition to essential nutrients, enough minority biologically active substances, such as essential vitamins and minerals. This group of substances include, for example, plant polyphenols, which act as effective antioxidants. A diet rich in natural antioxidant substances contributes to the prevention of serious civilization diseases, especially heart and blood vessels. People have always tried to enrich their diet with the resources of the biologically active substances. Particularly in spring, when stored foods lost their nutritional value, several wild plants came in. These have traditionally been used as a source of vitamins and other necessary substances. In our regions, they are traditionally a young nettle, but also some members of the family of crucifers. The aim of the bachelor thesis will be to select a set of suitable wild growing plants, to take samples for analysis and to determine the content of selected biologically active substances. A liquid chromatographic technique will be used to analyze the selected biologically active polyphenols contained in the plant material. It is a modern separation analytical technique, with which selected biologically active compounds are determined with high reliability.
