20.500.12556/DKUM-60245 ANTIOKSIDATIVNE LASTNOSTI EKSTRAKTOV NEKATERIH RASTLINSKIH MATERIALOV ANTIOXIDATIVE PROPERTIES OF EXTRACTS OF SOME PLANT MATERIALS Namen diplomskega dela je bil določiti antioksidativno aktivnost ekstraktov rastlinskih materialov in njihovih mešanic. Za določitev antioksidativne lastnosti ekstraktov smo uporabili radikalsko DPPH metodo, nato smo dobljene podatke obdelali s programom Design-Expert 7.0. Rezultati kažejo, da je med posameznimi ekstrakti rastlinskih materialov (ingver, koriander, origano, preslica, rožmarin), ki smo jih uporabili, najbolj antioksidativno aktiven ekstrakt rožmarina, ekstrahiran z vodo pri temperaturi 92 °C. Med pripravljenimi mešanicami ekstraktov (ingver-preslica-origano-rožmarin, ingver-preslica, koriander-rožmarin, koriander-rožmarin-origano in origano-preslica) se antioksidativno najbolje odziva mešanica origano-preslica ekstrahirana z vodo pri temperaturi 80 °C, po preteku časa 24 ur. The main purpose of thesis was to determine antioxidant activity from extracts of the plant materials, and their mixtures. To determine antioxidant activity we used the radical DPPH method. Resulting data were processed by the program Design-Expert 7.0 .The results show that among the various plant materials used (ginger, coriander, oregano, horsetail, rosemary) was the most active antioxidant rosemary at a temperature of 92 °C. Among the prepared extracts mixtures (ginger-horsetail, oregano-rosemary, ginger-horsetail, coriander-rosemary, coriander-rosemary-oregano and oregano-horsetail) the highest antioxidant response shows in oregano-horsetail extracted with water at a temperature of 80 °C, after a period of 24 hours. antioksidativna aktivnost ingver koriander origano preslica rožmarin antioxidant activity ginger coriander oregano horsetail rosemary true true false [T.
