| Summary: | In this present study, rose hip and hawthorn powders were investigated against three pathogenic bacteria strains: Staphylococcus aureus,Escherichia coliși Klebsiella pneumoniae. The chemical composition and antiradical activity of the plant extracts were investigated. The antiradical activity of the hydroalcoholic extracts of rose hip is 85.11 ± 0.02 and hawthorn -80.27 ± 0.23% DPPH inhibited, which correlates with the high content of polyphenolic and flavonoid compounds. The content of β-carotene and lycopene in the liposoluble extracts of rose hip is 14.85 times and 28.83 times higher than in hawthorn extracts. The rose hip powders show an antimicrobial activity pronounced to Staphylococcus aureus.In the case of Escherichia coliand Klebsiella pneumoniaeantimicrobial activity of hips is on average 1.3 times higher than that hawthorn powders.The rose hip powders showed the best inhibitory activity against Staphylococcus aureus, Gram-positive bacteria, followed by Escherichia coliand Klebsiella pneumoniae-Gram-negative bacteria. The investigated plant powders have shown promising antimicrobial potential against pathogenic microorganisms and can be used in the food industry to reduce the microbial contamination of raw materials and food. |
