Abstract: The antimicrobial activity of the extracts from Dictyophora indusial by 7 different solvents was tested with Sac-charomyces cerevisiae, Aspergillus niger, Escherichia coli, Bacillus subilis, Staphylococcus aureus, to explore the optimal extraction solvent. The results showed that Dictyophora indusial extracts by 2 solvents had bioactive substances to restrain the growth of Bacillus subilis hypha, and the antimicrobial activity of methanol extract was relatively strong, with the inhibition diameter against Bacillus subilis about 38.56 mm, followed by the ethyl acetate extracts, with the inhibition diameter about 31.66 mm. In view of the high and low extraction efficiency and antimicrobial activity in different solvents, the best one to extract antimicrobial activity substance from Dictyophora indusial was ethyl acetate.
