The Impact of Methamidophos to the Activity of Antioxidant Compounds in Chinese Cabbage

In this paper, the content of soluble protein and the activity of SOD, GSH, GST, CAT, GPX in Chinese cabbage were determined in the following 7 days after sprayed by 0.5 g/m² Methamidophos. The results indicated that the content of all parameters didn’t change obviously in the first day. In the 2-6 day, the content of protein, and the activity of GSH, SOD and CAT in Chinese cabbage were higher than the control, but the content of GPX and GST were relatively lower. At the 7th day, all parameters revived to the level of control sample. The results demonstrated that treated by Methamidophos, the antioxidant compounds of Chinese cabbage were induced to withstand the toxicity of Methamidophos.
