Figure 3: Effects of H2O2 on contents of baicalin, baicalein, wogonoside, and wogonin. The contents of both baicalin and wogonoside in roots of Scutellaria baicalensis increase soon after treatment with 0.002 μmol/L and 0.2 μmol/L H2O2, meanwhile, the contents of both baicalein and wogonin increase, indicating that under slightly stress, flavonoid is the basic and effective tool. At 20 μmol/L H2O2, the contents of both baicalein and wogonin increase insignificantly, showing the flavonoid glycoside may be transform into aglucon with higher activity, to work at full strength. Data were based on 3 times repeat
