Correlation coefficients (r) between antioxidants properties and colour intensity of honey.
| Parameters | TPC | TFC | IC50 | FRAP | Colour Intensity |
|---|---|---|---|---|---|
| TPC | 1.000 | ||||
| TFC | 0.802 | 1.000 | |||
| IC50 | −0.886 | −0.572 | 1.000 | ||
| FRAP | 0.981 * | 0.691 | −0.863 | 1.000 | |
| Colour intensity | 0.165 | −0.010 | 0.182 | 0.303 | 1.000 |
TPC = Total phenolic contents, TFC = Total flavonoids content, IC50 = Free radical scavenging activity, FRAP = Ferric reducing antioxidant power. (r) near to +1 or −1 indicates strong relationship and near to 0 indicates weak/no relationship. *Correlation is significant at p < 0.05.
