Biologická aktivita sekundárních metabolitů rostlin XXX. Základní screening vybraných taxonů na anticholinesterasovou aktivitu. / Biological activity of plants secondary metabolites XXX. Basic search of selected taxons on anticholinesterase activity.

CHARLES UNIVERSITY Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical Botany Candidate: Diana Karaščáková Supervisor: prof. RNDr. Lubomír Opletal, CSc. Title of diploma thesis: Biological activity of plants secondary metabolites XXX.; Basic search of selected taxons on anticholinesterase activity As part of the study of the biological activity of secondary metabolites, 7 taxa of higher plants were selected. The study deals with basic research of summary and alkaloid extracts prepared from morphological parts of plants Annona muricata (leaves), Leonotis leonurus (perch), Turnera diffusa (perch), Hamelia patens (perch), Uncaria guianensis (bark), Allamanda cathartica (perch) and Morinda citrifolia (leaves). To elucidate the presence of the major types of secondary metabolites, extracts were prepared and subjected to detection reactions by TLC using ten detection reagents. After detection by Dragendorff's reagent of ethyl acetate extracts, alkaloids were significantly present only in Annona muricata. Alkaloids were not detected in the bark of Uncaria guianensis. Using the Ellman method, the extracts were tested for potential inhibitory activity against human brain cholinesterases, using both recombinant enzymes. No significant active substances were present in any of the measured...
