摘要
目的:建立同时测定镇惊泻火颗粒中芒果苷、芦荟大黄素、大黄素和大黄酚含量的方法。方法:采用高效液相色谱法。色谱柱为Capcell Pak C18(250 mm×4.6 mm,5μm),流动相为乙腈-0.1%甲酸水溶液(梯度洗脱),流速为1.0 ml/min,检测波长为254nm,柱温为20℃结果:芒果苷、芦荟大黄素、大黄素和大黄酚的质量浓度分别在10.180-101.800、2.016-20.160、1.072-10.720、1.024-10.240μg/ml范围内与各自峰面积积分值呈良好的线性关系(r分别为0.9998、0.9996、0.9995、0.9996);精密度、稳定性、重复性试验的RSD≤1.4%(n均为6);平均加样回收率分别为98.05%、97.39%、97.91%和98.93%,RSD分别为1.3%、1.5%、1.2%和1.4%(n均为6)。结论:该方法准确、稳定、重复性好,可用于镇惊泻火颗粒的质量控制。
OBJECTIVE:To establish a method for the content determination of mangiferin,aloe-emodin,emodin,chrysophanol in Zhenjing xiehuo granule. METHODS:HPLC method was adopted. The determination was performed on Capcell Pak C18(250 mm×4.6 mm,5 μm)column with mobile phase consisted of acetonitrile-0.1% formic acid(gradient elution)at the flow rate of 1.0 ml/min. The detection wavelength was set at 254 nm. The column temperature was 20 ℃ RESULTS:The linear ranges were10.180-101.800 μg/ml for mangiferin(r=0.999 8),2.016-20.160 μg/ml for aloe-emodin(r=0.999 6),1.072-10.720 μg/ml for emodin(r=0.999 5)and 1.024-10.240 μg/ml for chrysophanol(r=0.999 6),respectively. RSD of precision,stability and reproducibility tests were all lower than 1.4%(n=6). The average recoveries were 98.05%(RSD=1.3%,n=6),97.39%(RSD=1.3%,n=6),97.91%(RSD=1.4%,n=6)and 98.93%(RSD=1.5%,n=6),respectively. CONCLUSIONS:The method is accurate,reliable,reproducible and specific,and is suitable for quality control of Zhenjing xiehuo granules.
