Sanguinarine is a best-known member of a relatively small group of quaternary benzo[c]phenanthridine alkaloids (QBAs). QBAs are widely distributed in the family Papaveraceae and, to a limited extent, in some species of the families Fumariaceae and Rutaceae. From a medical perspective, QBAs have many important properties. In addition to antitumour activity,(More)
Macleaya microcarpa (Maxim.) Fedde belongs to the genus Macleaya, family Papaveraceae. Together with the better known and more frequently studied species M. cordata (Willd.) R. Br. it is a main source of quaternary benzo[c]phenanthridine alkaloids. Using HPLC we determined the content of eight isoquinoline alkaloids in the aerial and underground parts of(More)
Local abiotic filters and regional processes (i.e., regional pools of species that are dispersal-limited to varying degrees) interactively structure the development of vegetation in human-disturbed habitats, yet their relative contributions to this process are still to be determined. In this study conducted in the Czech Republic, we related plant species(More)
