Hemp is unique plant with many therapeutic effects thanks to its large content of substances. This bachelor thesis brings information about characterization of main biological active substances in cannabis sativa, which are described in theoretical part of this thesis and determined in experimental part of this thesis. As a main active substance were determined antioxidants and cannabinoids for which the liquid chromatography method was optimized. This bachelor thesis also describes the antimicrobial effect of active cannabis substances for which it is used in the cosmetic industry. This antimicrobial activity has been studied in terms of the effect against dandruff, which is primarily caused by the high incidence of Malassezia yeasts on the skin of human hair. For the experimental part, the extracts of the technical hemp and more specific varieties of Bialobrzeskie and Finola were tested, which were further used for the preparation of the anti-dandruff shampoo. By analyzing the active substances in hemp extracts, the uniform result was obtained - the highest content of antioxidants and cannabinoids was reached by preparing of extract from dried hemp flowers. In the last part of the thesis, the antimicrobial effect of hemp extracts and prepared hemp shampoos was determined on selected strains of microorganisms and it was observed antimicrobial activity in extracts and shampoos againts Malassezia furfur yeast.
