ND, not detected; Abbreviation: TIHCAs, total individual hydroxycinnamic acids; Data are expressed as mean ± standard deviation of triplicate samples; Different superscripts between rows represent significant differences between samples (p < 0.05); Except 3-p-CoQA was quantified with p-coumaric acid, 5-FQA was quantified with ferulic acid, other phenolics were quantified with their own standard curves (mg/g DW).
