| Abstract [eng] |
Plants are a rich source of biologically active compounds with various useful properties [1]. Sea buckthorn has a wide spectrum of useful compounds which are nutritious and can be found in berries, leaves, twigs and bark. The sea buckthorn industry is dependent on its berries, but there are almost no applications for its secondary biomass use, which alone reaches about 12–15% [2]. This study focused on the use of sustainable solvents for the sea buckthorn berry pomace and leaf extracts preparation. Biologically active compounds, such as phenolic and proanthocyanidins from the buckthorn berry pomace and leaf extracts were measured using spectrophotometric analysis. The extracts were used for anti-microbial activity against Escherichia coli ATCC 8739, Staphylococcus aureus ATCC 25923, Salmonella typhimurium ATCC 14028, Bacillus cereus ATCC 11778, Listeria monocytogenes ATCC 13932. The highest concentration of phenolic compounds content in sea buckthorn berry pomace extract was determined 4.13 mg/g of dry material (DM) and in leaf extract 61.22 mg/g of DM. The highest concentration of proanthocyanidins in sea buckthorn leaf extract was determined 27.58 mg/g of DM. These identified concentrations are considered sufficient to exhibit measurable antibacterial activity against food spoilage microbes and food pathogens. The largest inhibition zone was determined in S.aureus ATCC 25923 (26.0 mm) and B.cereus ATCC 11778 (22.0 mm) bacterial strains where induced by leaves aqueous extract. This research shows a potential of sea buckthorn berry pomace and leaves as a source of bioactive, antibacterial compounds, which can be used in various types of industries. |
