HPLC测定清金化痰汤中黄芩苷和栀子苷的含量
摘要
目的:建立清金化痰汤剂中黄芩苷和栀子苷的测定方法。方法:采用高效液相色谱法
色谱柱Agilent C18(4.6mm×250 mm
5μm)
柱温30℃
测定黄芩苷流动相为甲醇-0.4%磷酸(47∶53)
检测波长为280 nm
流速:0.8 mL.min-1
检测波长为280 nm;测定栀子苷流动相为甲醇-水(25∶75)
检测波长为238 nm
流速1 mL.min-1。结果:传统清金化痰汤剂中黄芩苷含量为221.59 mg/剂
黄芩苷平均回收率为97.97%
栀子苷为335.73 mg/剂
栀子苷的平均回收率为98.36%。结论:此法简便快速
准确稳定
重现性好
成本低。
Abstract
Objective:To establish the method for determination of baicalin and geniposide in the Qingjin Huatantang.Method:High performance liquid chromatography was applied on a Agilent C18(4.6 mm × 250 mm
5μm) column at temperature 30 ℃
the mobile phase for baicalin consisted of methanol and 0.4% phosphoric acid(47:53) at detection wavelength of 280 nm
the flow rate was 0.8 mL.min-1;the mobile phase for geniposide consisted of methanol and water(25:75) at detection wavelength of 238 nm
the flow rate was 1 mL.min-1.Results:The content of baicalin in Qingjinhuatantang was 221.59 mg /dose
the content of geniposide was 335.73mg /dose.The mean recovery of baicalin and geniposide was 97.97 % and 98.36 % respectively.Conclusion:This method is simple
