The content of phenolic compounds and antioxidant capacity in three colors of petals cress(Tropaeolum majus L.) was evaluated. Petals colors red cress, orange and yellow were driedat room temperature; then they were conditioned for extracting its bioactive components,which were quantified showing significant difference (p<0.05) between colors. The highestconcentration of total phenols is in the orange color, followed by red and yellow (917.05;799.35 and 442.02 mg AGE/g sample). For quantification of total flavonoids, the highestcontent is in the red, followed by orange and yellow (2.184; 1.185 and 0.867 mg QE /gsample). As for the total tannins, the highest content is in the red followed by orange andyellow (342.92; 333.77 and 291.53 mg ATE/g sample). With respect to the antioxidantcapacity by DPPH and ABTS methods, the highest content is in the orange color, followed by red and yello...
