Description
Summary:•Effect of pesticide residues on medicinal herbs following ionising radiation.•Irradiation decreased polyphenolic content and antioxidant potential of Salvia leaves.•Parathion radiolysis products compensate the decline of the antioxidant capacity.•γ-Radiation breaks down parathion without inducing significant losses in polyphenols. The γ-irradiation effects on polyphenolic content and antioxidant capacity of parathion-pretreated leaves of Salvia officinalis plant were investigated. The analysis of phenolic extracts of sage without parathion showed that irradiation decreased polyphenolic content significantly (p
