Abstract
Summary Hyperforin is a prenylated phloroglucinol derivative which occurs in the plant Hypericum perforatum L. It has several medicinally important properties (antidepressant, anti-inflammatory, proapoptotic, antibacterial and antiangiogenic). To enable its medicinal use, it is necessary to investigate its potential genotoxic effect on human cell lines. We also observed an anticlastogenic effect of hyperforin towards the indirect mutagen benzo(a)pyrene. Benzo(a)pyrene is a widespread polycyclic aromatic hydrocarbon. We performed experiments on human tumor cell line HepG2, using the in vitro mammalian chromosome aberration test. We investigated two cytogenic parameters: the number of aberrant metaphases and the total number of chromosome aberrations. We found out that hyperforin was not genotoxic on human cell line HepG2. The second part of our results implies that hyperforin had an anticlastogenic effect against the indirect mutagen benzo(a)pyrene in our experimental conditions. In future we will continue our research by using another range of hyperforin concentrations, other cell lines and other chemical mutagens.
