Objective: To study the antimicrobial activities of petroleum ether extract from Green Forsythia suspensa. Method :The petroleum ether extract was subjected to column chromatography on silica gel using petroleum ether with increasing volume of ethyl acetate as eluent to give different fractions. The antimicrobial activities of different fractions on Staphy lococus aureua

Escherichia coli and Candida albicans were studied by K-B paper dispersion. Result: The petroleum ether extract from green F. suspense showed antimicrobial activity against tested mold. But the antimicrobial activities of all the fractions were not relevant to the concentration of extract. Conclusion: The antimicrobial activities of different fractions on S. lococus aureua

E. coli and C. albicans were significant.
