Antioxidant capacity: Table 1 shows antioxidant capacity together with percent inhibition of DPPH radicals and IC 50 of the methanolic leaf extracts of seven plant species. Antioxidant capacity ranged from 116.0 to 1.8 µmol TE g-1 DW with Rosmarinus sp. and Zataria Multiflora having the highest antioxidant capacity. Percent inhibition of DPPH radicals followed the same order as antioxidant capacity and ranged from 93.4 to 3.03 percent.
