TITLE: | |
摘要: | 目的:建立测定复方黄葛降糖片中盐酸小檗碱含量的方法。方法:采用超高效液相色谱法。色谱柱为Acquity UPLC BEH C18,流动相为乙腈-0.1%磷酸(21 ∶ 79,V/V),流速为0.3 ml/min,检测波长为345 nm,柱温为30 ℃,进样量为1.0 μl。结果:盐酸小檗碱检测进样量线性范围为0.008 16~0.081 6 μg(r=0.999 9);精密度、稳定性、重复性试验的RSD<1%;加样回收率为97.05%~98.96%(RSD=0.66%,n=6) 。结论:该方法操作简便,精密度、稳定性、重复性好,可用于复方黄葛降糖片中盐酸小檗碱含量的测定。 |
ABSTRACT: | OBJECTIVE: To establish a method for the content determination of berberine hydrochloride in Fufang huangge jiangtang tablet. METHODS: UPLC was performed on the column of Acquity UPLC BEH C18 with mobile phase of acetonitrile-0.1% H3PO4(21 ∶ 79,V/V) at flow rate of 0.3 ml/min, the detection wavelength was 345 nm, column temperature was 30℃, and the volume injection was 1.0 μl. RESULTS: The linear range of berberine hydrochloride was 0.008 16-0.081 6 μg(r=0.999 9); RSDs of precision, stability and reproducibility were lower than 1%; average recovery was 97.05%-98.96%(RSD=0.66%,n=6). CONCLUSIONS: The method is simple, precise, stablity and reproducible, and can be used for the quality control of Fufang huangge jiangtang tablet. |
