Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical Botany and Ecology Author: Mgr. Radka Kvapilová Supervisor: RNDr. Jitka Vytlačilová, Ph.D. Title of rigorous thesis: EVALUATION OF BIOLOGICAL ACTIVITY USING ARTEMIA SALINA Traditional Chinese medicine originated in ancient China and has evolved over thousands of years. TCM therapist use herbal medicines and body practices. Nowadays, Chinese medicine continues to develop and is used by millions of people around the world. The aim of this study was to evaluate the toxicity of these products - Epimedii herba, Salviae miltiorrhizae radix, Zanthoxyli fructus pericarpium, Nelumbinis folium a Gardeniae fructus. The experiment was conducted on organism Artemia salina. These experiments were evaluated after the 24 hours and the LC50 values were calculated. Toxicity declined in order: Zanthoxyli fructus pericarpium > Gardeniae fructus > Nelumbinis folium > Epimedii herba > Salviae miltiorrhizae radix. Key words: Zanthoxyli fructus pericarpium, Gardeniae fructus, Nelumbinis folium, Epimedii herba, Salviae miltiorrhizae radix, Artemia salina.

Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical Botany and Ecology Author: Radka Kvapilová Supervisor: RNDr. Jitka Vytlačilová, Ph.D. Title of diploma thesis: Antiprotozoal activity of alkaloids II. The development of new antiprotozoal agents for the treatment of infections is very important. Natural substances can be the source of effective drugs. The aim of this study was to evaluate the antiprotozoal activity of these alkaloids - canadine, scoulerine, tetrahydropalmatine and stylopine. The experiment was conducted on typical model organism Tetrahymena thermophila. Percentage inhibition of the organism was determined using the MTT assay. Subsequently median inhibitory concentration IC50 of the test substances was calculated. From our alkaloids stylopine had the greatest antiprotozoal activity. Antiprotozoal activity decreased in the following order stylopine > canadine > scoulerine > tetrahydropalmatine. Key words: Tetrahymena thermophila, antiprotozoal activity, canadine, scoulerine, tetrahydropalmatine, stylopine
