Evaluation of the antioxidant activities of aqueous ...

The antioxidant activities of the aqueous extracts of seven wild plants were investigated, using both in vitro and in vivo assays. The former relied on the use of 2,2-diphenyl-1-picrylhydrazyl (DPPH) and the latter, on the sensibility towards hydrogen peroxide of the yeast sod1 mutant. The studied plants were all wild, collected at the Ccamarrara hill (4000 m.a.s.l. Cusco, Peru), and of the ...

This study aims to evaluate antioxidant activity of aqueous and ethanolic extracts of Xylopia villosa stem bark. The quantitative study of polyphenols showed that ethanolic extract (75.00 ± 3.82 g/L EqAG) contains more than the aqueous extract (55.83 ± 1.67 g/L EqAG). It is the same for the quantitative analysis of total flavonoids where ethanolic extract (135.00 ± 1.44 g/L EqQ) contains ...
