Free radical scavenging activity of the crude solvent extracts of bee pollen and corn pollen. A. mellifera bee pollen and corn pollen were extracted sequentially with methanol (CMEb, CMEp), DCM (CDEb, CDEp) and hexane (CHEb, CHEp) prior to assaying for free radical scavenging activity using the DPPH assay in comparison to the reference standard of ascorbic acid. Data are shown as the mean ± 1 SEM, derived from three independent repeats. Means with a different letter are significantly different (p < 0.05).
