Biological activity of plant metabolites XXVIII. Alkaloids from selected cultivars of Narcissus cyclamineus REDOUTÉ and their influence on acetylcholinesterase and butyrylcholinesterase. JANURA M.: Diploma work, Charles University in Prague, Faculty of Pharmacy in Hradec Králové, Department of Pharmaceutical Botany and Ecology, Hradec Králové 2015, Czech Republic. Abstract: The summary extracts of alkaloids from bulbs of N. cyclamineus esp. N. cyclamineus cv. Jenny, N. cyclamineus cv. Little Witch, N. cyclamineus cv. Rapture, N. cyclamineus cv. Surfside, N. cyclamineus cv. Peeping Tom, N. cyclamineus cv. Warbeld and N. cyclamineus cv. Skater's Waltz were obtained by the procedures common for this type of compounds. The alkaloid extracts were analyzed by GC/MS and the probable occurrence of individual alkaloid substances was observed. These extracts were also assayed for HuAChE and HuBuChE inhibitory activity. N. cyclamineus cv. Surfside with IC50 = 61,26 ± 6,42 µg/ml and N. cyclamineus cv. Warbeld with IC50 = 85,43 ± 11,13 µg/ml have the best results in inhibition of HuBuChE. The best inhibitory activity on HuAChE has N. cyclamineus cv. Warbeld with IC50 (HuAChE) = 36,82 ± 4,50 µg/ml. Key words: Narcissus, Acetylcholinesterase, Butyrylcholinesterase, GC/MS, Alzheimer's disease.
