摘要:

目的:研究紫地榆乙酸乙酯部分和水部分对粘性放线菌生长、产酸及粘附的影响。方法:首先测定紫地榆乙酸乙酯部
分和水部分对粘性放线菌最低抑菌浓度(MIC),再以低于MIC 的4 个浓度配制含药的TPY液体培养基测定紫地榆乙酸乙酯部
分和水部分对粘性放线菌最低杀菌浓度(MBC)、产酸及粘附的影响。结果:紫地榆乙酸乙酯部分和水部分对粘性放线菌的最
低抑菌浓度(MIC)分别为4.500 g/L、9.000 g/L,最低杀菌浓度(MBC)分别为9.000 g/L、18.000 g/L;一定浓度的紫地榆乙酸乙酯
部分和水部分对粘性放线菌的产酸和粘附有一定的抑制作用。结论:紫地榆有可能是一种潜在的天然防龋药物,值得进行更
深入的研究。

Abstract:

Objective: To investigate the effect of the ethyl acetate part and the water Part of Geranium strictipes R. Kunth on the
growth, acidogenicity, adhesion of Actinomyces viscosus (A.v). Methods: Actinomyces viscosus was chosen as the experimental
bacteria. And then the effects of the ethyl acetate part and the water portion of G. strictipes on the growth(including the minimum
inhibitory concentration and the minimum bactericidal concentration), acid generation and adhesion were assessed. Results: The MIC of the ethyl acetate part and the water portion of G. strictipes against A.v was 4.500 g/L ,9.000 g/L, the MBC of the ethyl acetate part and the water Part of G. strictipes against A.v was 9.000 g/L ,18.000 g/L; it was found that the ethyl acetate part and the water Part of G. strictipes can inhibit the acid generation and adhesion of the A.v effectively. Conclusion: The ethyl acetate part and the water Part of G. strictipes may be an effective anti-caries agent.
