    Efecto antioxidante y citoprotector de extractos de plantas con actividad antimicrobiana por Pérez Narváez, Oscar Alberto

    Publicado 2018
    “…In the present study, antimicrobial, antioxidant and cytoprotective properties were evaluated in plants collected in municipality of Santiago, Nuevo León, Mexico; obtaining the leaf, stem and root (if any) ethanol extracts of A. xalapensis, M. malacophylla and T. cubense against strains of nosocomial importance such as S. aureus, P. aeruginosa and S. maltophilia; the greatest antimicrobial activity against S. aureus were the A. xalapensis stem and leaf extracts, MBC of 2.6 ± 0.3 mg/mL and 2.9 ± 0.5 mg/mL respectively, and the highest antioxidant activity by the methods of DPPH (1,112.1 ± 70.6 µmol ET/g 1,206.6 ± 68.6 µmol ET/g respectively) and ABTS•+ (1,864.0 ± 135.6 µmol ET/g 1750.7 ± 110.1 µmol ET/g respectively). Those extracts selected in this study, for their good antimicrobial and antioxidant activity were not hemolytic, the highest value was 3.1 ± 0.4 % of A. xalapensis stem at a 1,000 ppm of concentration; while cytoprotective capacity of this extract for human erythrocytes against AAPH-induced hemolysis was 98.5 ± 0.9% at 400 ppm of concentration, being to that concentration the best protective activity (100%) presented by the A. xalapensis leaf extract, and the T. cubense leaf, stem and root extracts. …”
