Inhibition of DNA damage . Protection against oxidative damage to pUC18 by TCME. Picture of agarose gel of pUC18 DNA showing bands of supercoiled (SC) and open circular (OC) forms. Lanes on the gel represent: (Lane 1) control DNA (no H2O2 or Fe2+); (Lane 2) reaction mixture without extract; (Lane 3–12) reaction mixture with extract of increasing concentration (0.5-5 μg/ml). **p < 0.01 and ***p < 0.001 vs 0 μg/ml.
