Ekstrakcija, izolovanje, sinteza i biološka aktivnost sekundarnih metabolita biljnih vrsta roda Hypericum dr Andrija Šmelcerović, vanredni profesor Medicinskog fakulteta u Nišu Rod Hypericum L. (Hypericaceae/Guttiferae) obuhvata oko 484 biljnih vrsta, rasprostranjenih širom sveta. Biljne vrste roda Hypericum se tradicionalno koriste u narodnoj medicine. Broj naučnih publikacija o biljnim vrstama ovog roda je značajno porastao usled farmakološkog značaja sekundarnih metabolita kantariona (Hypericum perforatum L.). Najznačajniji biokativni sastojci ovog roda su: (i) naftodiantroni, od kojih su najpoznatiji hipericin i pseudohipericin, (ii) derivati floroglucinola, pre svih hiperforin i adhiperforin, i (iii) flavonoidi, hiperozid, rutin, kvercetin i drugi. Hipericin i pseudohipericin deluju kao antivirotici, hiperforin je jedan od nosilaca antidepresivnog dejstva ekstrakata biljnih vrsta roda Hypericum, dok flavonoidi pokazuju antioksidatvnu aktivnost. U ovom predavanju biće predstavljeni rezultati istarživanja o ekstrakciji, izolovanju, sintezi i biološkoj aktivnosti sekundarnih metabolita biljnih vrsta roda Hypericum.
