The aim of this thesis was to study the effect of the acetylsalicylic acid on the stimulation of plant immunity and thus the influence on the content of the active constituents in Silybum marianum L. plants. The main active constituents of Silybum marianum L. seeds are silybine, silydianine, isosilybine, silycristine, usually expressed as silymarine content, and taxifoline. These constituents have antihepatotoxic effect and many different protective effects on numerous organs and cells. Knowledge about stress and elicitation, origin, botanical characterization, growth, development and cultivation of Silybum marianum L. were summarized before the research.The small-plot experiment was set up in Hluboká nad Vltavou in 2013. Plants of Silybum marianum were divided into four groups and then three goups were treated three times during the vegetation with the acetylsalicylic acid of three different concentrations - 10-3 mol.l-1 (high), 10-4 mol.l-1 (medium) a 10-5 mol.l-1 (low). Every single one group was treated with only one concentration of the acetylsalicylic acid. The last group was treated only with water and served as a control group. The preparation of the extracts was being held with using mixture of acetone, methanol and water. The extracts were determined by High Performance Liquid Chromatography.The effects of each chosen concetration of acetylsalicylic acid (high, medium, low) on the active constituents in seeds were not statistically proven compared to seeds without aplication of the elicitor (control group). The ineffectiveness of the elicitor should have been also caused by nonoptimal condition of plants due to various abiotic and biotic stressors.
