目的 建立金银花超微粉体不同极性部位的指纹图谱,并研究其与抑菌活性的相关性。方法 采用系统溶剂提取法得到6个不同极性部位,分别采用HPLC法进行测定,同时选择体外抑菌药理指标进行活性测定;用多元线性回归分析揭示化学信息与抑菌指标的相关关系,寻找与药理指标密切相关的物质群。结果 确定以醋酸乙酯提取部位的HPLC指纹图谱来制定金银花的抑菌活性指纹图谱。结论 应用该方法建立的金银花粉体的质量标准科学、合理、实用。

Objective To establish the fingerprint of Lonicera japonica superfine powder with different polarity and study its correlation of antibacterial activity. Methods Six different polarity extracts were obtained using the solvent system extraction and then were detected by HPLC with gradient elution. Pharmacological activities were detected by antibiotic indexes in vitro. The correlation between the pharmacological indexes and the information of HPLC fingerprint was discovered by multiple linear regression analysis and compound groups related to pharmacological indexes were obtained. Results Antibacterial effect fingerprint of L. japonica can be established by HPLC fingerprint of ethyl acetate fraction. Conclusion The method developed is practical and can be used for evaluating the quality control of L. japonica powder.
