1 Total phenolic content analyzed as gallic acid equivalent (GAE) μg/mg of extract; values are the average of triplicate experiments. 2 Total flavonoid content analyzed as quercetin equivalent (QE) μg/mg of extract; values are the average of triplicate experiments. 3 µg/g of extract values are the average of triplicate experiments. Values with different superscripted letters are significantly different (p < 0.05). ND = Not detectable.
