摘要
目的:对多种中药的活性成分进行提取并筛选出新的有效治疗阴道炎的组方。方法:参考中医验方,通过平板稀释法和K-B纸片法测定不同pH条件下中药提取物对大肠杆菌、金黄色葡萄球菌、绿脓杆菌和白色念球菌的抑菌效果。选择苦参、蛇床子、川椒和黄柏的提取物为组方成分,并通过正交实验确定各组分的最佳比例。建立小鼠、大鼠阴道炎模型,通过在体实验观察组方的抑菌效果。结果:中药组分的比例不同,其抑菌效果也不同。在pH 6的条件下,1 m l药液中含100μl蛇床子-川椒(2∶1)共提挥发油,苦参和黄柏醇提物各50μl时组方的抑菌效果最好。结论:该复方组分少,疗效佳,且适应于阴道炎患者阴道内的pH值范围,有望成为治疗阴道炎的有效药物。
Objective： To study on the various proportions of Radix Sophorae Flavescentis, Cortex Phellodendri, Fructus Cnidii and pericarp of Zanthoxylum bungeanum Maxim in the formulas, whose antimicrobial effects on E. coli, S. aureus, P. aeruginosa and C. albicans under different pH values were compared in vitro. Methods： According to Chinese ancient proved recipe, the K-B method and plate diluting method were adopted to measure antimicrobial activity, and orthogonal design to ascertain the herbal formula in vitro. Finally, murine models were established to test the antimierobial activity in vivo through vaginal membrane irritancy experiment, negative rate of pathogeny and pathological grade of vaginal membrane. Results ： The results suggested that formulas with different proportions of the herbs had diverse antimicrobial activities, and the effect was shown to be most obvious when one milliliter drug contains 100 μl Fructus Cnidii-pericarp of Zanthoxylum bungeanum（ 2：1 ） co-extracted volatile oil and 50μl Radix Sophorae Flavescentis and Cortex Phenodendri ethanol extraction respectively under pH6. The antimicrobial effect of the formula, which hardly had any membrane irritancy, was better than Jie Eryin in vitro and vivo. Conclusion： The fromula has few components and better effect, and adaptation to the pH value of vaginitis. It is a promising alternative for gynecological diseases.
