Abstract:

Antibacterial activity of rape bee pollen extract was investigated using Oxford cup method. Results indicated that 0.5% formic acid extraction fraction from ethanol extract of rape bee pollen exhibited strong antibacterial activity. Minimum inhibitory concentrations (MIC) of formic acid extraction fraction against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Bacillus subtilis were 25, 50, 50 mg/mL and 100 mg/mL, respectively. HPLC analysis showed that bioactive components with antibacterial activity in formic acid elution fraction were weakly polar substances.

Key words: rape bee pollen, antibacterial activity, ethanol extract
