The presented values are the means of three determinations (n = 3), with standard deviations for each column, different superscript letters differ significantly (p ≤ 0.05) by 2-sided Tukey’s HSD

The superscripts denote statistically significant values obtained by 2-sided Tukey analysis using SPSS program
