Phenolic content and antioxidant activity of different Iranian populations of Anabasis aphylla L.

Abstract

The Anabasis aphylla L. aerial parts was harvested from five different populations located in Golestan National Park, Iran. The phenolic content and antioxidant potencies of the ethanolic extracts were measured using the Folin–Ciocalteu and 2,2-diphenyl-1-picrylhydrazyl (DPPH) methods, respectively. Moreover, the effects of two factors soil electrical conductivity and soil acidity on phenolic content and antioxidant properties of the extracts were evaluated. Consequently, no significant difference between different populations of Anabasis aphylla L. in terms of total phenol content was detected; however, a significant difference was observed between the electrical conductivity of the soil samples. The studied factors showed no significant correlation between the electrical conductivity and soil acidity with the total phenol and antioxidant effect, although a negative correlation between total phenol and IC₅₀ (–0.81) was identified. In conclusion, the present study the effect of two factors of soil acidity and electrical conductivity on the amount of total phenol is not confirmed.
