OBJECTIVE To investigate the in vitro effects on Staphylococcus aureus,Escherichia coli,Pseudomonas aeruginosa,Klebsiella pneumoniae,Candida albicans and Cryptococcus neoformans of different Girardinia herba separated fractions( HGSFs).METHODS Inhibition zone diameters were measured to investigate the effects on bacteria and fungi of HGSFs. The minimal inhibitory concentrations( MIC) and the minimum bactericidal /fungal concentration( MBC /MFC) of HGSFs were determined with micro-liquid dilution method. RESULTS All of HGSFs apparently inhibited effect to Staphylococcus aureus,MIC is 1. 25-5 mg·mL-1. Fraction 1( UF100) and 2( UF50) could can inhibit the growth of Escherichia coli and Klebsiella pneumonia and MIC was 5-10 mg·mL-1but had no effect on Pseudomonas aeruginosa and wnicellular fungi. The different HGSFs,at maximum concentration of crude Girardinia herba( 20 mg·mL-1),were not confirmed killing the experimental bacteria and single-celled fungi strains.CONCLUSION HGSFs have antibacterial effects on the part of the bacteria strains,but can not inhibit or kill the single-celled fungi strains.
