Figure 5

Ferric-reducing antioxidant power (FRAP) of Pinus densiflora bark (PDB) extracts from different solvents. Activity is expressed as ascorbic acid equivalent (AAE) mg/g extract. Values are mean ± SD from three independent experiments. p < 0.01, p < 0.001, ns: nonsignificant, compared to E0 (water extract).
