Antibacterial Activities of Different Extract Fractions from Dryopteridis Crassirhizomatis Rhizoma
Objective: To study the antibacterial activities of different extract parts from Dryopteridis Crassirhizomatis Rhizoma. Method: The crude extracting of Dryopteridis Crassirhizomatis Rhizoma was extracted in 70% ethanol for 72 h
and the extracts of five fractions (petroleum
chloroform
EtoAc
n-BuoH and water) were prepared with liquid-liquid separation method. The antibacterial activities of different fractions on six strains (Escherichia coli
Staphylococcus aureus
Bacillus subtilis
Saccharomyces cerevisiae
Aspergillus flavus and Rhizopus nigricans) were studied by K-B paper dispersion. Result: All five parts had certain antibacterial effects on test strains
and the overall antibacterial activities were increase with the increase of the drug dose. The chloroform and EtoAc fractions had the stronger antibacterial activities
and the water fraction had the minimum antibacterial activities. Conclusion: Different fractions had different antibacterial activities on test strains.
