在口腔鼻咽部常见的致病菌有葡萄球菌,链球菌和乳酸杆菌等,可引起多种疾病,用中药医治具有不同程度的抑菌作用及很好的疗效。为了更好地为临床用药提供参考,并研制新的杀菌制剂,我们参考Namba从中药中筛选抗龋齿药的方法研究了一些常用中药的杀菌活性(最小杀菌浓度和最短杀菌时间)。结果表明所筛18种中药中有13种显示了较强的杀菌作用。现简介如下: 材料和方法 (一)中药样品液的制备 1.厚朴。(Magnolia officinalis Rehder etwilson)粉用95％乙醇回流提取减压浓缩液用水沉淀,置冰箱过夜,倾去上清液,
Staphylococcus, Streptococcus, and Lactobacillus are the common pathogens in the oral nasopharynx, which can cause various diseases. The use of traditional Chinese medicine has different degrees of antibacterial effect and good efficacy. In order to provide reference for clinical drug use and develop new bactericidal agents, we studied the bactericidal activity (minimum bactericidal concentration and minimum bactericidal time) of some commonly used Chinese herbs by referring to Namba’s method of screening anti-caries medicines from Chinese medicine. The results showed that 13 of the 18 kinds of Chinese herbs screened showed a strong bactericidal effect. The brief introduction is as follows: Materials and Methods (I) Preparation of Chinese herbal sample solution 1. Magnolia. (Magnolia officinalis Rehder et wilson) powder was extracted with 95% ethanol under reflux, and the decompression concentrate was precipitated with water, placed in a refrigerator overnight, and the supernatant was decanted.
