REC-2006—A Fractionated Extract of Podophyllum hexandrum Protects Cellular DNA from Radiation-Induced Damage by Reducing the Initial Damage and Enhancing Its Repair In Vivo
Figure 6
Effect of REC-2006 on chemically induced superoxide anions. The reaction mixture containing of 0.52 M sodium pyrophosphate, pH 8.3, 186 M phenazine methosulphate, 300 M nitroblue tetrazolium and 780 M NADH was mixed with varied concentrations of REC-2006 individually and incubated for 90 s at 30°C. The purple-colored chromogen formed was measured spectrophotometrically at 560 nm in triplicate. The values are expressed as mean ± SD of data from three independent assays (NS, not significant; *P .05, **P .01).
