Mean values within a column with the same letter are not significantly different at p 0.05 using Tukey’s HSD test. The first letter of the alphabet for the highest values, the next for statistically significant decreasing values. The mean values ± SD from n = 4 independent measurements (extracts) or from n = 6 independent measurements (quercetin).
