Kohelová E: Alkaloids of Amaryllidaceae family: isolation, structural identification, biological activity. II Diploma thesis, Charles University in Prague, Faculty of Pharmacy in Hradec Králové, Department of Pharmaceutical Botany and Ecology, Hradec Králové, 2017, 77p. The aim of the diploma thesis was a preparation of alkaloidal extract from fresh bulbs of Narcissus cv. PROFESSOR EINSTEIN to izolate two Amaryllidaceae alkaloids by column and thin layer chromatography. Subsequently these alkaloids were subjected to structural MS and NMR analysis and tested for biological activity against human cholinesterases (HuAChE and HuBuChE) and for cytotoxic activity. In cooperation with the Faculty of Agrobiology, Food and Natural Resources, Czech University of Life Sciences Prague, antifungal and antimicrobial activities of alkaloids were tested, and in cooperation with Faculdade de Medicina da Universidade de Lisboa Portugal antimalarial activity of alkaloids was studied. Isolated substances were identified as galanthamine, caranine and pluviine. Pluviine was isolated in an amount allowing only structural analysis. In the test for determining cholinesterase inhibitory activity of caranine the following values were obtained: IC50, HuAChE = 320 ± 42 μM a IC50, HuBuChE = 486 ± 56 μM. Galanthamine (IC50,...
