Effects of Chelidonine on Superoxide Dismutase and Catalase Activity in Pieris rapae L
Download as PDF
The experiment used chelidonine, berberine, coptisine and sanguinarine as materials, studied the effects of different concentrations of single alkaloid on the activity of superoxide dismutase (SOD) and catalase(CAT) in Pieris rapae L. The results showed that the concentrations (2 mg/L) of chelidonine, berberine and sanguinarine had the high activation rate.The activation rates of superoxide dismutase were 181.82%, 109.52% and 789.4% respectively. The activation rates of catalase were 225.54%, 173.54% and 105.9% respectively. The highest activation rate of superoxide dismutase of 1 mg/L coptisine was 70.73%, and 2 mg/L coptisine was -19.11%. The highest activation rate of catalase was 109.91%, and 2 mg/L was -9.33%. These results indicated that high concentration of coptisine had inhibition effect on SOD and CAT.
