Significant differences in the same row are indicated with different lowercase letters (comparison among the 13 cultivars at the same crop season, p < 0.05) and with different capital letters (comparison between crop seasons for the same cultivar, p < 0.05). Quantitative results for some compounds determined in 4 varieties from those 13 selected for this study are included in this table (to contain its size); therefore, the results shown herewith were treated together with those from Table 2 and Table 3 to carry out ANOVA analysis. Secoiridoids were quantified in terms of Oleuropein.
