|The EC50values for the free radical scavenging activity of three different crude extracts from bee pollen and corn pollen, plus the reference standard (ascorbic acid) for comparison|
|Bee corn pollen extracts|
|CMEb||428.6 ± 29.0b||ND|
|CDEb||7.47 ± 0.12a*||1|
|Floral corn pollen extracts|
|CMEp||365.2 ± 38.8bb||1|
|CDEp||212.3 ± 13.6aa**||1|
|Ascorbic acid||8.57 ± 0.24*||1|
ƒ EC50 values were calculated by linear regression (r2 = the correlation coefficient). ND represents no available data. Means within a group of three crude extracts of each sample with a different superscript letter (bee pollen extracts) or pair of letters (floral pollen extracts) are significantly different (p ≤ 0.05; One way ANOVA), whilst a significant difference between groups is indicated by * or **.
