Figure 6
Effect of R. emodi rhizome extracts (50 g) on the protection of supercoiled DNA (pBR322) against oxidative damage caused by UV-photolysed H2O2 (3%). C = untreated non-irradiated DNA (control); = untreated UV-irradiated DNA (control); = UV-irradiated, aqueous extract treated; = UV-irradiated, methanolic extract treated; SC DNA = supercoiled DNA; OC DNA = open circular DNA; LIN DNA = linear DNA.
