中文摘要: 目的:建立同时测定牛黄宁宫片中6种成分含量的方法。方法:采用高效液相色谱法。色谱柱为TC-C18,流动相为甲醇-0.05%磷酸(梯度洗脱),流速为1.0 mL/min,检测波长为280 nm,柱温为25 ℃,进样量为10 μL。结果:甘草苷、盐酸小檗碱、连翘苷、黄芩苷、大黄素和大黄酚检测质量浓度线性范围分别为3.2~320 μg/mL (r=0.999 9)、8.8~880 μg/mL (r=0.999 8)、5.6~560 μg/mL(r=0.999 5)、2.0~200 μg/mL(r=0.999 9)、4.4~440 μg/mL(r=0.999 9)、2.0~200 μg/mL (r=0.999 7);精密度、稳定性、重复性试验的RSD<6.0%;加样回收率分别为96.34%~97.25%(RSD=0.33%,n=6)、96.12%~98.06%(RSD=0.82%,n=6)、96.36%~99.09%(RSD=1.02%,n=6)、95.84%~97.32%(RSD=0.65%,n=6)、95.83%~97.92%(RSD=0.88%,n=6)、98.60%~99.65%(RSD=0.42%,n=6)。结论:该方法操作简便,精密度、稳定性、重复性好,可用于牛黄宁宫片中6种成分含量的测定。
英文摘要: OBJECTIVE: To establish a method for simultaneous determination of 6 components in Niuhuang ninggong tablets. METHODS: HPLC method was adopted. The determination was performed on TC-C18 column with mobile phase consisted of methanol-0.05% phosphate acid (gradient elution) at the flow rate of 1.0 mL/min. The detection wavelength was set at 280 nm, and the column temperature was 25 ℃. The sample size was 10 μL. RESULTS: The linear ranges of glycyrrhizin, berberine hydrochloride, baicalin, baicalin, emodin and chrysophanol were 3.2-320 μg/mL(r=0.999 9), 8.8-880 μg/mL(r=0.999 8), 5.6-560 μg/mL (r=0.999 5),2.0-200 μg/mL(r=0.999 9), 4.4-440 μg/mL (r=0.999 9),2.0-200 μg/mL(r=0.999 7), respectively. RSDs of precision, stability and reproducibility tests were all lower than 6.0%. The recoveries were 96.34%-97.25%(RSD=0.33%,n=6), 96.12%-98.06%(RSD=0.82%,n=6), 96.36%-99.09%(RSD=1.02%,n=6),95.84%-97.32%(RSD=0.65%,n=6), 95.83%-97.92%(RSD=0.88%,n=6), 98.60%-99.65%(RSD=0.42%,n=6), respectively. CONCLUSIONS: The method is simple, accurate, stable and reproducible, and can be used for content determination of 6 components in Niuhuang ninggong tablets.
