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 **.
