TIMEA GHERMAN, VIOLETA POPESCU, RAHELA CARPA, MARIA RAPA, GEORGIANA LUMINITA GAVRIL, MIRCEA CRISTIAN DUDESCU, DORIN BOMBOS POTENTIAL USE OF GALIUM VERUM ESSENTIAL OIL FOR ANTIBACTERIAL PROPERTIES IN GELATIN BASED HYDROGELS PREPARED BY MICROWAVE IRRADIATION TECHNIQUE Galium verum essential oil (EO) loaded gelatin hydrogel was prepared by microwave-assisted polymerization method. FT-IR analysis indicated no chemical interaction between the hydrogel matrix and EO. Good swelling behavior, increased thermo- and mechanical- properties was attributed to the synergistic effects of the secondary structure of gelatin after gelation and intermolecular hydrogen-bonding interactions between the hydrogel matrix and EO ingredient’s. Antibacterial activity was investigated by the agar diffusion method.
