Charles University, Faculty of Pharmacy in Hradec Králové Department of Pharmacognosy and Pharmaceutical Botany (16-16230) Author: Aneta Maršálková Supervisor: PharmDr. Kateřina Hradiská Breiterová, Ph.D. Title of thesis: Cytotoxic activity of selected Narcissus cultivars in vitro. Key words: Narcissus, Amaryllidaceae alkaloids, cytotoxicity, HepG2 The main focus of this diploma thesis is the screening of summary alkaloidal extracts of selected cultivars of the genus Narcissus for their cytotoxic activity against HepG2 liver carcinoma cell line. In the second phase, the cytotoxic activity of the majorly represented Amaryllidaceae alkaloids (AmA) was screened, followed by an IC50 value determination. All studied alkaloidal extracts underwent also GC-MS and GC-FID qualitative and quantitative analysis to identify as many alkaloids as possible. A total of 23 alkaloids, namely 11,12-didehydroanhydrolycorine, 1-O-acetyl-10-norpluviine, 9-O-methylpseudolycorine, anhydropseudolycorine, assoanine, dehydroassoanine, dihydrolycorine, epi-norgalanthamine, galanthamine, galanthine, haemanthamine, hippeastrine, incartine, caranine, lycoramine, lycoraminone, lycorine, narwedine, norpluviine, pluviine, pseudolycorine, sanguinine, tazettine and several unspecified alkaloids of the homolycorine structural type were...
