o:1585 DETERMINATION OF BIOLOGICAL POTENTIAL OF TILIA CORDATA FLOWER EXTRACTS en Extraction is a very important stage in the isolation, as well as the identification of different bioactive compounds in the plants. The aim of this research was to produce aqueous and ethanolic extracts from Tilia cordata flowers, as well as to determine its antioxidant and antimicrobial potential. Ethanolic extract was characterized with higher (p<0.05) ability to capture free DPPH radicals compared to the aqueous extract. From the point of ability to chelate iron ions can be proved that ethanolic extract was characterized with slightly higher (p<0.05) values compared to the aqueous one, whereas at the highest tested concentration both of the extracts (51.57%, i.e. 49.03%, respectively) had higher (p<0.05) antioxidant potential compared to the citric acid (12.66%). These values were followed by IC50 values. Furthermore, ethanolic linden extract had higher (p<0.05) antimicrobial potential against most of the tested strains compared to the aqueous linden extract. Even that ethanolic extract showed the highest activity against Staphylococcus aureus, Bacillus cereus, Listeria monocytogenes, Escherichia coli, Yersinia enterocolitica, Proteus vulgaris and Pseudomonas aeruginosa only in one case,against Listeria monocytogenes (15.9 mm), showed higher (p<0.05) activity compared to the tetracycline. According to that, ethanolic linden flower extract showed good antioxidant and antimicrobial potential while it can be used in the food industry for producing functional food with increased biological value.
