*2.3. Statistical Analysis*

Data were expressed as mean ± standard deviation of triplicate measurements. The PC software "Excel Statistics" was used for the calculations. The analysis correlated the values of antibacterial activity, specifically to the inhibition zone data, to total polyphenols and phenolic composition, using the free software environment for statistical computing and graphics R (https://www.r-project.org/) [15].
