【摘要】:目的:建立同时测定益肾衍嗣丸中阿魏酸、梓醇、大黄素和大黄素甲醚含量的方法。方法:采用双波长高效液相色谱法。色谱柱为Kromasil-C_(18),流动相为甲醇-0.1%磷酸溶液(78∶22,V/V),流速为1.0 mL/min,检测波长为280 nm(阿魏酸、大黄素和大黄素甲醚)、210 nm(梓醇),柱温为30℃,进样量为10μL。结果:阿魏酸、梓醇、大黄素和大黄素甲醚检测质量浓度线性范围分别为0.090 8~2.270 0μg/mL(r=0.999 9)、0.199 0~4.975 0μg/mL(r=0.999 3)、0.354 0~8.850 0μg/mL(r=0.999 9)、0.3360~8.400 0μg/mL(r=0.999 7);定量限分别为14.66、8.75、10.26、13.68 ng,检测限分别为5.66、2.67、3.78、4.25 ng;精密度、稳定性、重复性试验的RSD2.0%;加样回收率分别为101.15%~102.73%(RSD=0.58%,n=6)、99.20%~101.69%(RSD=1.20%,n=6)、100.90%~101.36%(RSD=0.16%,n=6)、95.64%~98.96%(RSD=1.49%,n=6)。结论:该方法准确可靠,操作简单,适用于益肾衍嗣丸中4种成分含量的同时测定。
[Abstract]:Objective: to establish a method for simultaneous determination of ferulic acid, catalpol, emodin and emodin methyl ether in Yishen Yansi pills. Methods: dual-wavelength high-performance liquid chromatography was used. The chromatographic column was Kromasil-C18, the mobile phase was methanol-0.1% phosphoric acid solution (78: 22V / V), the flow rate was 1.0 mL / min, the detection wavelength was 280 nm (ferulic acid, emodin and emodin methyl ether) 210nm (catalpol), the column temperature was 30 鈩,
