Abstract

In this paper,the author studied the methods of picking up toxin from Cecospora capsici,and the results showed that it was the best to use polar organic solvent for extraction.This way was produced precipitate.Supernatant and precipitate were carried out on the biometrics.The material in the supernatant had pathogenic roles.It can be concluded that the material produced from liquid culture of C.capsici which had pathogenic roles was a small molecule compounds.
