The Antioxidant Capacities of Leaf Extracts from Salvia viridis L.

Abstract

This research was conducted at Yozgat Bozok University to define the antioxidant activity of Salvia viridis L. grown in the field and in vitro conditions. The leaves of the plants grown under field conditions were collected in the pre-flowering period. The leaf extracts prepared with methanol were used in the analysis. DPPH (1,1-Diphenyl-2-picrylhydrazyl) free radical screening activity was used to identify antioxidant activity. The total phenolic, flavonoid, and DPPH IC50 values of S. viridis L. grown in the field and under in vitro conditions were found as 184.15 ± 36.70 mg GAE g-1 and 66.46 ± 0.19 mg GAE g-1, 212.92 ± 11.18 mg QE g-1 and 212.92 ± 11.18 mg QE g-1, 117.51 mg ml-1and 185.40 mg ml-1, respectively. According to the findings of this study, it was determined that leaves of S. viridis L. grown in field conditions exhibited more antioxidant activity than in vitro conditions.
