dc.description.abstractArtemisia annua, u narodu poznata kao slatki pelin, je zeljasta biljka iz familije Asteraceae. Od davnina se upotrebljava u tradicionalnoj medicini kao biljka koja ima antimalarijsku aktivnost, usled prisustva seskviterpenskog laktona artemisina. Takođe, sadrži fenole i flavonoide, te se svrstava u biljke sa antioksidativnim, antiinfektivnim i antiinflamatornim dejstvom. Cilj rada bilo je ispitivanje hemijskog sastava i antioskidativne aktivnosti etanolnog ekstrakta slatkog pelina. U etanolnom ekstraktu herbe A. annua određen je sadržaj ukupnih fenola metodom po Folin-Ciocalteu. Rezultati su izraženi kao mg ekvivalenta galne kiseline/g suvog ekstrakta (mg EGK/g s.e.). Ukupni flavonoidi određeni su spektrofotometrijski praćenjem formiranja kompleksa sa AlCl3. Rezultati su izraženi kao mg ekvivalenta kvercetina/g suvog ekstrakta (mg EK/g s.e.). Antioksidativna aktivnost određena je in vitro testovima inhibicije 2,2-difenil-1-pikrilhidrazil (DPPH), hidroksil (OH), nitrozo (NO) radikala i testom inhibicije lipidne peroksidacije. Rezultati su izraženi kao koncentracija pri kojoj je neutralisano 50% radikala tj. koncentracija pri kojoj je inhibisano 50% procesa lipidne peroksidacije (IC50). Visokoefikasnom tečnom hromatografijom (HPLC) izvršena je detaljna hemijska karakterizacija. Rezultati su izraženi kao μg/g suvog ekstrakta.sr
dc.description.abstractArtemisia annua, popularly known as sweet wormwood, is a herbaceous plant from the family Asteraceae. Since ancient times, it has been used in traditional medicine as a plant that has antimalarial activity, due to the presence of the sesquiterpene lactone artemisinin. It also contains phenols and flavonoids because it is classified as a plant with antioxidant, anti -infective and anti-inflammatory effects. The aim of the work was to examine the chemical composition and antioxidative activity of the ethanolic extract of sweet wormwood. In the ethanolic extract of A. annua herb, the content of total phenols was determined using the Folin-Ciocalteu method. The results are expressed as mg gallic acid equivalents/g dry extract (mg GAE/g d.e.). Total flavonoids were determined spectrophotometrically by monitoring the formation of complexes with AlCl3. Results are expressed as mg quercetin equivalents/g dry extract (mg QE/g d.e.). Antioxidant activity was determined by in vitro tests of inhibition of 2,2-diphenyl-1-picrylhydrazyl (DPPH), hydroxyl (OH), nitroso (NO) radicals and lipid peroxidation inhibition test. The results are expressed as the concentration at which 50% of the radicals are neutralized, or the concentration at which 50% of the lipid peroxidation process is inhibited (IC50). Detailed chemical characterization was investigated by high-performance liquid chromatography (HPLC). The results are expressed as μg/g dry extract.sr
