HPLC法测定净石灵胶囊中芍药苷的含量(毕业论文8520字) 摘 要:建立采用高效液相色谱测定净石灵胶囊中芍药苷含量的方法。采用色谱柱为Agilent Eclipe DB C18柱(150mm x4.6mm,5μm),以乙腈-水(13:87)为流动相,流速为1ml/min,检测波长为230nm,柱温为30℃。芍药苷进样量在在0.04~0.36μg范围内与峰面积线性关系良好(r=0.9995),方法的平均回收率为97.30%,RSD为1.26%。高效液相色谱法简便、准确,重现性好,可作为净石灵胶囊的含量测定方法。 关键词:高效液相色谱法;净石灵胶囊;芍药苷;含量测定 Determination of Paeoniflorin in Jingshiling Capsules by HPLC Abstract: HPLC method was established for the determination of Paeoniflorin in Jingshiling capsule. A Agilent Eclipe DB C18 column(150 mm×4.6 mm,5 μm) was choosed with the mobile phase of acetonitrile and water (13∶87), and the flow rate was 1 mL/min, the detection wavelength was 230 nm.The column temperature was 30℃. The linear range of Paeoniflorin was 0.04~0.36μg and correlation coefficient was 0.9995.The average recovery was 97.3% and RSD was 1.26% . HPLC is simple, accurate and reproducible method, It could used for quality control of Jingshiling capsule. Key words:HPLC;Jingshiling capsule; Paeoniflorin; Determination![]() |
