Antioxidative activities of pine, oak, and lily pollen extracts were evaluated based on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging ability and inhibition of lipid peroxidation in animal tissues. Each pollen was extracted with 50% ethanol, 100% ethanol or water. DPPH radical-scavenging capacity of 50% ethanol extract (EC∧50 40.0 mg/mL) of pine pollen was higher than those of water (46.8 mg/ml) and 100% ethanol (131.2 mg/mL) extracts of pollen. Fifty percent ethanol (3.2 mg/mL) was also better than 100% ethanol (4.5 mg/mL) and water (8.3 mg/mL) for extraction of oak pollen.
