pharmaceutical applications. In this study, six different Iranian species of plantago were studied to determine their antioxidant activity as well as their total phenolics, flavonoids, flavonols, chlorophyll, carotenoids, and anthocyanin content. The highest contents for total phenolics (92.37 mg GAE/g DW) and total flavonoids (57.16 mg QE/g DW) were found in P. major, whereas the highest total flavonols content (46.07 mg QE/g DW) and carotenoids (0.13 mg/g DW) were detected in P. cornopus. The least 1,1-diphenyl-2-picrylhydrazy (DPPH) activity (0.66 mg/ml) was found in P. major. Also, total antioxidant capacity was in the following order P. major P. cornopus P. subulata P. lanceolate ≥ P. maritima P. ovata. Preliminar comparison of the Iranian plantago species identified them as good sources of phenolic compounds. Hence, P. major followed by P. cornopus were identified as the richest species in phenolics content with high antioxidant activity.
