篇名: HPLC法测定养阴合剂中黄芩苷的含量
TITLE:
摘要: 目的:建立测定养阴合剂中黄芩苷含量的方法。方法:采用高效液相色谱法。色谱柱为 SunFire C18,流动相为甲醇-水-磷酸(43 ∶ 57 ∶ 0.2,V/V/V),流速为1.0 ml/min,检测波长为280 nm,柱温为30 ℃,进样量为10 μl。结果:黄芩苷的检测进样量线性范围为0.055 75~1.115 μg(r=0.999 9);精密度、稳定性、重复性试验的RSD<2%;加样回收率为95.39%~98.44%(RSD=1.19%,n=6)。结论:该方法简便、快速,结果准确,适用于养阴合剂中黄芩苷的含量测定。
ABSTRACT: OBJECTIVE: To establish a method for the content determination of baicalin in Yangyin mixture. METHODS: HPLC was performed on the column of SunFire C18 with mobile phase of methnol-water-phosphoric acid (43 ∶ 57 ∶ 0.2,V/V/V) at a flow rate of 1.0 ml/min, the detection wavelength was 280 nm,  column temperature was 30 ℃, and the volume injection was 10 μl. RESULTS: The linear range of baicalin was 0.055 75-1.115 μg(r=0.999 9); RSDs of precision, stability and reproducibility test were lower than 2%; recovery was 95.39%-98.44% (RSD=1.19%,n=6). CONCLUSIONS: The method is simple, rapid and accurate, and suitable for the content determination of baicalin in Yangyin mixture.
