摘要:

目的:研究紫地榆中4种活性成分对2种致龋菌生长及产酸的影响。方法:测定紫地榆4种活性成分对2种致龋菌的最
低抑菌浓度及最低杀菌浓度,测定其对2种致龋菌生长和产酸的影响。结果:没食子酸、五倍子酸甲酯、儿茶素、鞣花酸对变形
链球菌的最低抑菌浓度为4.000、4.000、1.000、1.000 g/L,最低杀菌浓度为8.000 、8.000 、2.000 、2.000 g/L;对粘性放线菌的最低
抑菌浓度为4.000、2.000、0.500、0.500 g/L,最低杀菌浓度为8.000、4.000、1.000、1.000 g/L。紫地榆活性成分对2种致龋菌的产
酸有一定程度的抑制作用。结论:紫地榆4种活性成分可影响致龋菌生长代谢并能有效抑制其产酸。

Abstract:

Objective:To investigate the effects of four active compounds of Geranium strictipes on the growth and acid production of
two kinds of cariogenic bacteria. Methods:Firstly, respectively determine the minimum inhibitory concentration (MIC) and the
minimum bactericidal concentration (MBC) of the active compounds of Geranium strictipes on two kinds of cariogenic bacteria. Then the
influence of active compounds of Geranium strictipes on the growth and acid production of two kinds of cariogenic bacteria were
determined. Results:The MIC of gallic acid, gallicin, catechins, ellagic acid on Streptococcus mutans respectively were 4.000, 4.000,
1.000, 1.000 g/L , while the MBC of gallic acid, gallicin, catechins, ellagic acid on Streptococcus mutans respectively were 8.000, 8.000,
2.000, 2.000 g/L ; The MIC of gallic acid, gallicin, catechins, ellagic acid on Actinomyces viscosus respectively were 4.000, 2.000,
0.500, 0.500 g/L , while the MBC of gallic acid, gallicin, catechins, ellagic acid on Actinomyces viscosus respectively were 8.000, 4.000,
1.000, 1.000 g/L. The active compounds of Geranium strictipes could inhibit the acid production of two kinds of cariogenic bacteria.
Conclusion:4 active compounds of Geranium strictipes can affect the growth and metabolism of two kinds of cariogenic bacteria,and
effectively inhibit the acid production.

Key words: Geranium strictipes, active compound, cariogenic bacteria, acid production
