Mai T. T.: Screening of biological activity of various species of the genus Kalanchoe, Diploma thesis, Charles University, Faculty of Pharmacy in Hradec Králové, Department of Pharmacognosy and Pharmaceutical botany, Hradec Králové 2023. The content of this diploma thesis was the screening of the biological activity of dried flowers, stems and roots of four species from plants of the genus Kalanchoe: Kalanchoe delagoensis Eckl. & Zeyh., Kalanchoe fedschenkoi Raym.-Hamet & H.Perrier, Kalanchoe blossfeldiana Poelln. and Kalanchoe manginii 'Wendy' Raym.-Hamet & H.Perrier. By boiling the dried parts of the plants with ethanol, the summary ethanolic extracts were obtained, which were subjected to control TLC to detect the presence of alkaloids using Dragendorff's reagent. The presence of alkaloids was confirmed in the species Kalanchoe blossfeldiana Poelln, Kalanchoe manginii 'Wendy' Raym.-Hamet & H.Perrier and Kalanchoe delagoensis Eckl. & Zeyh. Furthermore, they were subjected to evidence reactions to identify the substances contained on TLC. In comparison with the literature, the presence of flavonoids, steroids substances, coumarins, triterpenes and alkaloids was confirmed in most plant extracts. Plants extracts of Kalanchoe blossfeldiana Poelln (AL-756 - extract from flowers and stems) and...
