Miklová V.: Cytotoxic and cholinesterase inhibitory activity of extracts from selected species of the Centaurea L. genus II. Diploma thesis, Charles University, Faculty of Pharmacy in Hradec Králové, Department of Pharmaceutical Botany, Hradec Králové, 2020. This Diploma Thesis was carried out at the Department of Pharmaceutical Botany FAF UK and it is a part of a screening of biologically active secondary metabolites of selected on taxa of the genera Centaurea L. and Psephellus L. in the family Asteraceae. Secondary metabolites are responsible for various effects on the human body. The study is focused on the phytochemical research of extracts prepared from aerial parts (cauloms with leaves) of Centaurea cyanus L., Centaurea stoebe L., Cyanus montanus (L.) Hill, Centaurea benedicta L., Centaurea jacea L., Centaurea macrocephala Muss. Puschk. ex. Willd, Centaurea solstitialis L., Centaurea nigra L., Centaurea scabiosa L., Psephellus bellus (Trautv.) Wagenitz, Centaurea pannonica (Heuff.) Hayek and Psephellus dealbatus (Willd) K. Koch. Both ethyl acetate and summary ethanolic extracts were prepared for detection of individual groups of secondary metabolites by thin-layer chromatohraphy. Consistently with previously published results, sesquiterpenes, flavonoids, coumarins, phenolic compounds,... |
