AB  - Vaccinium myrtillus leaf waste extracts were prepared using lactic acid+amonium acetate and maceration, heat- and ultrasound-assisted extractions (HAE and UAE, respectively). The obtained extracts were characterized via analysis of total polyphenol content (TPC), pH, zeta potential, conductivity, density, surface tension, viscosity, and antioxidant potential. The TPC was the highest in the extract prepared in HAE (53.0±0.9 mg GAE/g), whereas the extracts from maceration and UAE possessed significantly lower TPC (50.4±0.7 and 49.5±0.4 mg GAE/g). The ABTS radical scavenging potential was the highest in the extract prepared in HAE (38.4±1.1 µmol TE/g), followed by the extract obtained using UAE (33.7±1.5 µmol TE/g) and maceration (30.2±1.7 µmol TE/g). The DPPH antioxidant capacity followed the same trend: HAE>UAE>maceration. The zeta potential was low in all extracts (2.66±0.48 mV for macerate, 2.57±0.20 mV for HAE, and 3.17±0.13 mV for UAE), while the conductivity was in the range of 1.87±0.13 and 1.84±0.11 mS/cm (maceration and HAE) to 2.10±0.11 mS/cm (UAE). The density varied from 1.105±0.009 g/mL for macerate to 1.122±0.006 and 1.117±0.001 g/mL for HAE and UAE extracts. There were no statistically significant differences in the surface tension and viscosity (~23.5 mN/m and ~5.5 mPa∙s). The highest TPC and antioxidant potential were measured in the extract obtained using HAE, whereas the extract prepared by ultrasound waves possessed the highest zeta potential and conductivity. Therefore, the extraction technique should be chosen depending on the future application of V. myrtillus extract.
