TITLE:
摘要: 目的:提高呼吸通口服液的质量标准。方法:采用薄层色谱法(TLC)对制剂中百部、黄芩、牛蒡子进行定性鉴别;采用高效液相色谱法(HPLC)测定制剂中黄芩苷的含量:色谱柱为Agilent Eclipse Plus-C18,流动相为甲醇-0.1%磷酸溶液(48 ∶ 52,V/V),流速为0.8 ml/min, 检测波长为280 nm, 柱温为25 ℃, 进样量为20 μl。结果:百部、黄芩、牛蒡子的TLC图斑点清晰,分离度好,阴性对照无干扰。黄芩苷检测进样量线性范围为0.378 0~3.779 5 μg(r=0.999 9);精密度、稳定性、重复性试验的RSD<2.0%;加样回收率为96.52%~104.95%(RSD=1.28%,n=9)。结论:提高的标准能更加有效地控制呼吸通口服液的质量。
ABSTRACT: OBJECTIVE: To establish the quality standard for Huxitong oral solution. METHODS: TLC was conducted for the qualitative identification of Stemona japonica, Scutellaria baicalensis and Fructus arctii; HPLC was adopted for the content determination of baicalin: the column was Agilent Eclipse Plus-C18 with mobile phase of methanol-0.1% phosphoric acid solution (48 ∶ 52,V/V) at a flow rate of 0.8 ml/min, the detection wavelength was 280 nm, column temperature was 25 ℃, injection volume was 20 μl. RESULTS: TLC spots of S. japonica, S. baicalensis and F. arctii were clear and well separated, with no interference in negative control. The linear range of baicalin was 0.378 0-3.779 5 μg (r=0.999 9); RSDs of precision, stability and reproducibility tests were lower than 2.0%; recovery was 96.52%-104.95% (RSD=1.28%,n=9). CONCLUSIONS: The improved standard can more effectively control the quality of Huxitong oral solution.
