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 C_(18),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20μl。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1.400-8.400μg(r=0.999 4)、0.152-0.912μg(r=0.999 6)、0.248-1.488μg(r=0.999 9)、0.128-0.768μg(r=0.999 4);定量限分别为84.85、3.15、15.03、7.76ng,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。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 C_(18) 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 μ g for linarin(r=0.999 6),0.248-1.488 μ g for berberine hydrochloride(r=0.999 9) and0.128-0.768 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.
