Antiradical DPPH activities are expressed as IC50 in µg/mL for extracts and compounds.
Expressed as µM trolox equivalents/g dry weight.
Expressed in percentage scavenging of superoxide anion at 100 µg/mL.
Total phenolic content (TPC) expressed as mg gallic acid/g dry weight.
Total flavonoid content (TFC) expressed as mg quercetin/g dry weight.
Extraction yields expressed in percent W/W extraction on the basis of fresh material.
Used as standard antioxidants. Values in the same column marked with the same letter are not significantly different (at p < 0.05).
