Figure 6: Effect of sodium hydrosulfiteon the contents of four flavones. The contents of both baicalin and wogonoside in roots of Scutellaria baicalensis increased soon after treatment with 0.0004 and 0.04 mmol/L sodium hydrosulfite, but the contents of both baicalein and wogonin failed to decrease, indicating that under slightly stress, flavonoid glycosides was the basic and effective tool. At 4.0 mmol/L sodium hydrosulfite, the contents of both baicalin and wogonoside decreased, while the contents of both baicalein and wogonin increased insignificantly, showing that the aglucons had higher activity. Data were based on three times repeat
