Correlation between hydroxycinnamic acid concentration and antioxidant activity.
| TP | CU | FE | RS | |
|---|---|---|---|---|
| Correlation | R | |||
| CU | −0.6489 | |||
| FE | −0.6397 | −0.1695 | ||
| RS | 0.8079 | −0.9726 | −0.0640 | |
| AA | 0.9691 | −0.8163 | −0.4307 | 0.9282 |
Data are expressed as the mean ± standard deviation. Correlation between CA and AA was not investigated because the CA values were not detectable (the values were lower than the quantification limit (0.04 mg·g−1 d.m.) S, rosmarinic acid; FE, ferulic acid; CU, coumaric acid; TP, total phenolic content; AA, antioxidant assay; R, correlation coefficient. P<0.05.
