目的建立化痰平喘片中黄芩苷的质量标准。方法采用HPLC法对化痰平喘片中黄芩苷进行含量测定,以C18化学键合硅胶为固定相,以甲醇-水-磷酸(47∶53∶0.2);检测波长为280nm。结果平均回收率为98.6%。RSD%为0.95%结论该方法可靠,操作简便,重现性好,可用于该制剂的质量控制。
Objective To establish the quality standard of baicalin in Huayu Pingchuan Tablets. Methods HPLC method was used to determine the content of baicalin in Huayu Pingchuan Tablets. C18 chemically bonded silica gel was used as the stationary phase with methanol-water-phosphoric acid (47∶53:0.2). The detection wavelength was 280 nm. The average recovery of the results was 98.6%. RSD% is 0.95% Conclusion This method is reliable, easy to operate, reproducible, and can be used for quality control of the formulation.
