TITLE: | |
摘要: | 目的:建立同时测定跌打丸中芍药苷和丹皮酚含量的方法,为提高其质量控制标准提供参考。方法:采用高效液相色谱法。色谱柱为 ZORBAX C18,流动相为乙腈-0.1%磷酸(梯度洗脱),流速为0.8 ml/min,检测波长为230 nm(芍药苷)、274 nm(丹皮酚),柱温为35 ℃,进样量为20 μl。结果:芍药苷和丹皮酚的检测进样量线性范围分别为0.514 8~1.544 5 μg(r=0.999 2)、0.643 2~1.960 4 μg(r=0.999 8);定量限分别为0.135 6、0.126 4 μg、检测限分别为0.067 8、0.063 2 μg;精密度、稳定性、重复性试验的RSD<2%;加样回收率分别为95.78%~97.27%(RSD=0.62%,n=6)、97.38%~98.38%(RSD=0.42%,n=6)。结论:该方法操作简便、重复性好、灵敏度高,可用于同时测定跌打丸中芍药苷和丹皮酚的含量。 |
ABSTRACT: | OBJECTIVE: To establish a method for the simultaneous determination of paeoniflorin and paeonol in Dirda pill,and provide reference for improving its quality control standard. METHODS: HPLC was performed on the column of ZORBAX C18 with mobile phase of acetonitrile-0.1% phosphoric acid (gradient elutio) at a flow rate of 0.8 ml/min, detection wavelength was 230 nm(paeoniflorin), 274 nm(paeonol), columne temperature was 35 ℃, injection volume was 20 μl. RESULTS: The linear range was 0.514 8-1.544 5 μg for paeoniflorin (r=0.999 2) and 0.643 2-1.960 4 μg for paeonol(r=0.999 8); the limits of quantification were 0.135 6, 0.126 4 μg, limits of detection were 0.067 8, 0.063 2 μg; RSDs of precision, stability and reproducibility tests were lower than 2%; recoveries were 95.78%-97.27%(RSD=0.62%,n=6) and 97.38%-98.38% (RSD=0.42%,n=6). CONCLUSIONS: The method is simple with good reprosucibility and high sensibility, and can be used for the simultaneous determination of paeoniflorin and paeonol in Dirda pill. |
