【Abstract】 Four kinds of solvents and three kinds of extracting methods were applied to extract effective antifungal compositions in the plant Xanthium sibiricum,and then the fungistatis obtained were tested with Botrytis cinerea,Rhizoctonia solani,Fusarium oxysporium,Cladosporium cucumerinum and Alternaric solani.The results showed that acetone was the best for was the best extracting solvents for the stem and leave,and carbinol the root of Xanthium sibiricum.The most suitable extracting method was continuous reflux extraction.更多还原
