ABSTRACT
Objective To study on antibacterial effect of active ingredient of se-enriched Macleya cordata.Methods Penicillin sodium and saline as control, detected the average inhibition zone diameter of se-enriched Macleya cordata group ( containing 0.96 mg/mL sanguinarine) on 9 common bacteria with disc agar diffusion method;20% methanol and saline as control, se-enriched Macleya cordata group which the average inhibition zone diameter was minimum, without se-enriched Macleya cordata group and penicillin sodium were diluted with 20% methanol, made concentration of 0.48, 0.24,0.12,0.06, 0.03 mg/mL.minimal inhibitory concentration ( MIC) of each treatment group was determined by agar dilution method, evaluated antibacterial effect of se-enriched Macleaya cordata group.Results se-enriched Macleya cordata group could improve antibacterial effect significantly, the average inhibition zone of 100 μg/mL sodium selenite treatment group was minimum(Φ15.33 mm);MIC of se-enriched Macleya cordata group on E.coli O1 , E.coli P22 , E.Dublin reduced from 0.96 to 0.24 mg/mL;MIC of S.typhimurium and S.suipare were 0.12 mg/mL;MIC of S.aureus and S.suis were 0.06 mg/mL; MIC of E.Dublin and L.murrayi were less than 0.03 mg/mL.Conclusion Se-enriched Macleya cordata improves the antibacterial effect signififcantly, and it lays the theoretical foundation for development and utilization of se-enriched Macleya cordata for future.
