Charles University, Faculty of Pharmacy in Hradec Králové Department of Pharmacognosy Candidate: Pavlína Zlochová Supervisor: PharmDr. Marie Kašparová, Ph.D. Title of diploma thesis: Secondary metabolites of plant cultures in vitro I. Key words: Suspension cultures, Trifolium pratense, phytoestrogens, flavonoids, isoflavonoids Explant cultures are source of plant secondary metabolites. Nevertheless the production of secondary metabolites is usually low in explant cultures. This production can be increased by elicitation metods. Suitable elicitor is added into the cultivate medium and leads to gene expression and production of secondary metabolites. The aim of this study was to observe the influence of sodium chloride on the production of flavonoids and isoflavonoids by the Trifolium pratense L. suspension culture (Tempus variety). The culture was cultivated on Gamborg nutriet medium with addition of 2 mg.l-1 2,4- dichlorophenoxyacetic acid and 2 mg.l-1 6-benzylaminopurine. Cultivation proceed in 25řC temperature and 16 hours light/8 hours dark period. Then determination of flavonoids in according to Czech Pharmacopoeia 2009 and the determination of isoflavonoids by HPLC method was performed. The best elicitation effect on the production of flavonoids was 175 mmol.l-1 of sodium chloride after a 3...
