In vitro antibiotic effect of the leaching solution of astragalus on cariogenic bacteria / 实用口腔医学杂志

Astragalus produced in Gansu were chosen as the raw material to leachate. Studied the antibiotic effects of the leaching solution on the cariogenic bacteria and compared with the imported bacteriostatic product MI. Streptococcus mutans and Lactobacilli were cultured in the medium for 24 h. The PH and A600 values were measured. Statistical analysis was conducted by using SPSS 13.0. The leaching solution of astragalus has the same inhibitory effects on the growth and acid production of streptococcus mutans and lactobacilli as MI.
