The emergence of multidrug-resistant bacteria has prompted the development of alternative
therapies, including the use of natural products with antibacterial properties. The antibacterial
properties of Zantaz honey produced in the Moroccan Atlas Mountains against Escherichia coli,
Pseudomonas aeruginosa, and Staphylococcus aureus was evaluated and analyzed using chemometric
tools. Minimum inhibitory concentration (MIC) and Minimum bactericidal concentration (MBC)
against S. aureus were the lowest (112.5 ± 54.5 mg/mL), revealing that this species was most sensitive
to Zantaz honey. P. aeruginosa showed an intermediate sensitivity (MIC= 118.75 ± 51.9 mg/mL), while
E. coli was the most resistant to treatment (MIC = 175 ± 61.2 mg/mL). Content of monosaccharides,
certain minerals, and phenolic compounds correlated with antibacterial activity (p < 0.05). Principal
component analysis of physicochemical characteristics and antibacterial activity indicated that the
parameters most associated with antibacterial activity were color, acidity, and content of melanoidins,
fructose, epicatechin, methyl syringate, 4-coumaric acid, and 3-coumaric acid. info:eu-repo/semantics/publishedVersion
