Abstract
So far, no studies have assessed the antibacterial properties of macerates of flower petals intended for human consumption. Previous studies have focused on the role of extracted flower components in inhibiting bacterial growth, not considering the petal tissue as a mixture of different components. The aim of this study was to assess the inhibitory effect of unpreserved macerates and juices derived from edible flower petals of Viola tricolor and T. patula on the population of Staphylococcus aureus ATCC 25923. Evaluation of the biostatic properties of flowers was carried out in two stages: using the Baird-Parker RPF culture method and the disc diffusion method. The reduction in the number of staphylococci by the macerates of the petals and their mixtures did not exceed 11% of the inoculum value. A low degree of inhibition of S. aureus ATCC 25923was found with T. patula macerate and sap in studies using both methods. The diffusion disc method in the study revealed the synergistic effect of the petals of both species on S. aureus ATCC25923 cells.
