All data are displayed as mean ± standard deviation (SD) of triplicated experiments from three independent sets of samples (n = 3). The superscript lowercase letters indicated statistically different contents of bioactive compounds in different samples prepared under the same extraction solvent, while superscript uppercase letters indicated statistically different contents of bioactive compounds in the same sample extracted under different solvent systems of at p < 0.05 using unpaired t-test. DW, dry weight; GAE, gallic acid equivalent; NA, not available; TPCs, total phenolic contents.
