a Peaks were positively identified based on the comparison of retention time and mass spectra with that reported in the literature. b Based on a reference by Liang et al. [28]. c Based on a reference by Wittenauer et al. [29]. d Based on a reference by Crupi et al. [30]. e Symbols bearing different capital letter (A–B) in the same row are significantly different at p < 0.05. f Based on extraction with methanol. g Based on extraction with ethanol. h Mean of triplicate analyses ± standard deviation.
