Abstract
In the present study the total phenolic content and antioxidant activity of Achillea wilhelmsii (three ecotypes), Anthemis susiana (two ecotypes), Anthemis wettsteiniana, Anthemis lorestanica, Matricaria aurea, Matricaria recutita, Acroptilon repens (two ecotypes) were evaluated. Methanolic extracts of the flowers, shoots and roots of these species were examined to identify the phenolic content (using Folin-Ciocalteus reagent) and antioxidant capacity (employing DPPH radical- scavenging activity). Results showed that the highest level of polyphenols and DPPH radical- scavenging activity typically belonged to the flowers following by the shoots. The flowers of the RA ecotype of A. wilhelmsii, A. wettsteiniana, M. aurea and the shoot of A. repens showed the highest level of polyphenols in their own group. In all species, a significant negative correlation for total phenolic content and EC50 value of DPPH radical scavenging activity was observed.
