金银花(Flos Lonicerae)是常用清热解毒药,有效成分主要是绿原酸和异绿原酸。绿原酸的含量多随产地、加工方法等的不同有较大的差异。本文就此进行了分析研究。材料、方法与结果仪器和试药六种金银花样品见下页表1;710分光光度计(上海第三分析仪器厂出品);层析用新华3号滤纸:规格30×20(cm);绿原酸标准品(试剂、进口分装ROTH);正丁醇、冰醋酸、95%乙醇均为分析纯。标准方法的确定称取适量的绿原酸标准 Flos Lonicerae is a commonly used heat-clearing and detoxifying drug. The active ingredients are mainly chlorogenic acid and isochlorogenic acid. The content of chlorogenic acid varies greatly depending on the place of production and processing method. This article has carried on the analysis research to this. Materials, methods and results Instruments and reagents Six kinds of honeysuckle samples are shown in the following table 1; 710 spectrophotometer (Shanghai Third Analytical Instrument Factory); chromatography with Xinhua No. 3 filter paper: specifications 30 × 20 (cm); green Raw acid standard products (reagents, imported packaging ROTH); n-butanol, glacial acetic acid, 95% ethanol are all analytically pure. Determination of standard methods weighs the appropriate amount of chlorogenic acid standards
