Dohnalova A: Alkaloids of Amaryllidaceae family: isolation, structural identification, biological activity. I; Diploma thesis, Charles University, Faculty of Pharmacy in Hradec Králové, Department of Pharmaceutical Botany and Ecology, Hradec Králové, 2017, 64 p. The Amaryllidaceae family includes bulbous, beautifully flowering plants that have been used for thousands of years in traditional medicine. The major chemical compounds found in this particular plant family are alkaloids, namely Amaryllidaceae alkaloids. Until now, more than 500 isoquinoline alkaloids have been discovered, which exhibit a diverse biological activity including antitumor and antibacterial. They are also able to inhibit acetylcholinesterase. The aim of the diploma thesis was to process 34 kg of fresh bulbs of Narcissus cv. PROFESSOR EINSTEIN and to prepare an alkaloidal extract. This extract was further divided by column chromatography to almost 500 fractions which were merged based on TLC into 27 subfractions. The subfractione No. 17 was selected for isolation of at least one pure alkaloid. Preparative TLC was used for the the isolation. One pure compound was obtained in crystalic form which was then subjected to structural analysis by EI-MS and NMR methods. Further studies of biological activities were performed in...
