脱油油樟叶提取物的体外抑菌活性研究
The antibacterial study on extracts from de-oiled leaves of Cinnamomum longepaniculatum against three of the pathogenic bacteria
摘要
Abstract
The antimicrobial activity of ethanol extracts from the de-oiled leaves of Cinnamomum longepaniculatum and system solvent extraction by petroleum,ethyl acetate and N-butanol against the Escherichiu coli ,Staphylococcus aureus, Salmonella. Minimum inhibition concentration ( MIC) , minimal bacteriocidal concentration(MBC)and time-kill curves of extracts were studied. And the activities against the three strains of bacterial were compared. The re-sultrs showed that,for E. Coli,the N-butanol extracts(MIC,MBC:7. 813,15. 625 mg/mL)>ethyl acetate extracts (MIC,MBC:15. 625,31. 125)>the ethanol extracts and water extracts(MIC,MBC:31. 25,62. 5)>petroleum ex-tracts(MIC and MBC>500). For S. Aureus, petroleum extracts and ethyl acetate extracts(MIC, MBC: 7. 813,15. 625)>N-butanol extracts(MIC,MBC:15. 625,31.125)>ethanol extracts and water extracts(MIC,MBC:31. 25, 62. 5). For Salmonella,ethyl acetate extracts(MIC,MBC:3. 9063,7. 813)>N-butanol extracts(MIC,MBC:15. 625, 31. 125)>water extracts(MIC,MBC:31. 25,62. 5)>petroleum extracts(MIC,MBC:31. 25,125). C. Longepanicu-latum had some antibacterial active compounds and the main active constituents existed in ethyl acetate extracts and N-butanol extracts. The extracts of de-oiled leaves of C. Longepaniculatum displayed concentration-dependent relationship with all the three pathogenic bacteria.关键词
