摘要: | 目的:建立同时测定参菊洗剂中苦参碱、蒙花苷、盐酸小檗碱和蛇床子素含量的方法。方法:采用高效液相色谱法。色谱柱为Dionex C18,流动相为乙腈-0.1%三乙胺水溶液(用磷酸调节pH至7.2)(梯度洗脱),流速为1.0 ml/min,检测波长为210 nm,柱温为30 ℃,进样量为20 μl。结果:苦参碱、蒙花苷、盐酸小檗碱和蛇床子素检测进样量线性范围分别为1.400~8.400 μg(r= 0.999 4)、0.152~0.912 μg(r=0.999 6)、0.248~1.488 μg(r=0.999 9)、0.128~0.768 μg(r=0.999 4);定量限分别为84.85、3.15、15.03、7.76 ng,检测限分别为24.13、0.89、4.27、2.20 ng;精密度、稳定性、重复性试验的RSD<2%;加样回收率分别为96.29%~99.06%(RSD=1.10%,n=9)、96.49%~98.27%(RSD=0.69%,n=9)、99.26%~101.13%(RSD=0.62%,n=9)、96.27%~98.64%(RSD=0.89%,n=9)。结论:该方法操作简便、结果准确、重复性好,可用于同时测定参菊洗剂中苦参碱、蒙花苷、盐酸小檗碱和蛇床子素的含量。 |
ABSTRACT: | OBJECTIVE: To establish a method for simultaneous determination of matrine, linarin, berberine hydrochloride and osthole in Shenju lotion. METHODS: HPLC was performed on the column of Dionex C18 with mobile phase of acetonitrle - 0.1% triethylamine (pH was adjusted to 7.2 with phosphoric) (gradient elution) at a flow rate of 1.0 ml/min, detection wavelength was 210 nm, column temperature was 30 ℃, and injection volume was 20 μl. RESULTS: The linear range was 1.400-8.400 μg for matrine (r=0.999 4), 0.152-0.912 μg for linarin (r=0.999 6), 0.248-1.488 μg for berberine hydrochloride (r=0.999 9) and 0.128-0.768 μg for osthole (r=0.999 4); limit of quantitation was 84.85, 3.15, 15.03, 7.76 ng, limit of detection was 24.13, 0.89, 4.27, 2.20 ng; RSDs of precision, stability and reproducibility tests were lower than 2%; recoveries were 96.29%-99.06% (RSD=1.10%,n=9), 96.49%-98.27% (RSD=0.69%,n=9), 99.26%-101.13%(RSD=0.62%,n=9) and 96.27%-98.64% (RSD=0.89%,n=9). CONCLUSIONS: The method is simple, accurate and reproducible, and can be used for the simultaneous determination of matrine, linarin, berberine hydrochloride and osthole in Shenju lotion. |
