TPC, total phenolic content; TFC, total flavonoid content; ABTS, 2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activity; DPPH, 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity; MDA, malondialdehyde inhibitory effect; FRAP, ferric ion reducing antioxidant power; VCEAC, vitamin C equivalent antioxidant capacity.
The results of TPC and TFC are presented as mg of gallic acid equivalent (GAE)/g and mg of rutin equivalent (RE)/g, respectively. The results of ABTS, DPPH, and MDA are presented as IC50 value (μg/mL). The results of FRAP are presented as mg of Fe(II) mg/g. The results of VCEAC are presented as mg of VCE/100 g dry weight.
