Substances Contained in Plants of the Nightshade Family (*Solanaceae*) and their Usage in Biology Teaching

The aim of the thesis titled "Substances contained in Plants of the Nightshade Family (Solanaceae) and their Usage in Biology Teaching" is to familiarize the reader with basic toxicological and pharmacological terms contained in the information on Nightshade plants (Solanaceae). Further it introduces Nightshade plants (Solanaceae) and their substances in more detail. It describes the use and abuse of these plants in poisoning, usage in traditional medicine, homeopathy and modern medicine. It outlines the history of the use and especially abuse of plants containing alkaloids. It also describes options for didactic use through laboratory work and assesses and compares the quality of information available in the literature for high school students. Information contained in this work can be practically used in teaching subjects such as toxicology, pharmacology and pharmacognosy at secondary schools with focus on the chemical and pharmaceutical industry. Key terms: Content Substances, Plant Alkaloids, Poisonous Plants, The Use and Abuse of Solanaceous Plants
