| CPW | 3.35±0.00 | 4.07±0.73 | 0.16±0.00 | 0.31±0.01 | 0.86±0.02 |
The results are expressed as the mean±SE (n=3).
GAE, gallic acid equivalent; RE, rutin equivalent; DPPH, 1-diphenyl-2-picrylhydrazyl radical scavenging activity; Alkyl, alkyl radical scavenging activity; Hydroxyl, hydroxyl radical scavenging activity.
