The Evaluation of the Antibacterial Activity of the Juice and Syrup of the Black Elderberry Plant Obtained from the Generative Organs

Key words: Sambucus nigra L., anti-bacterial properties, Е.coli, Staphylococcus aureus, strain, elderberry juice, elderberry syrup Recently, there has been a growing interest in the development of studies of natural antimicrobial active agents from plant raw materials. Antibiotic resistance has led to an urgent need to develop new and innovative antimicrobial agents and among potential sources, plants can be considered as a good alternative. One of the sources of biologically active compounds is Black Elderberry (Sambucus nigra L.) from the Sambucus genus. Studies of the Black Elderberry juice and syrup obtained infused in the dark showed a temporary moderate antibacterial activity in the amount of 50ml on the growth of the bacterium Staphylococcus aureus. Elderberry juice has a moderate antibacterial activity, and the syrup has even higher antibacterial activity on the growth of E.coli bacteria. Elderberry samples show higher antibacterial activity against E. coli than against Staphylococcus aureus. The influence of light leads to a decrease in the antibacterial activity of elderberry juice and syrup. Of the studied samples, elderberry syrup infused in the dark and the dye obtained from elderberries show high antibacterial activity on the growth of E. coli and moderate activity on the growth of St. aureus.
