篇名: RP-HPLC法同时测定荷叶颗粒中3种有效成分的含量
TITLE:
摘要: 目的:建立同时测定荷叶颗粒中芦丁、槲皮素、荷叶碱含量的方法。方法:采用反相高效液相色谱法。色谱柱为Hypersil ODS2,流动相为乙腈-水(含0.3%磷酸和0.4%三乙胺)(梯度洗脱),流速为1.0 ml/min,检测波长为256 nm,柱温为25 ℃,进样量为10 μl。结果:芦丁、槲皮素、荷叶碱的检测进样量线性范围分别为0.012~0.240、0.010 4~0.208、0.015~0.300 μg(r均为0.999 9);精密度、稳定性、重复性试验的RSD<2.0%;加样回收率分别为98.5%~101.3%、99.1%~101.6%、98.9%~101.7%,RSD分别为1.1%、1.0%、1.2%(n=6)。结论:该方法操作简便、结果准确可靠,可为荷叶颗粒的质量控制提供参考。
ABSTRACT: OBJECTIVE:To establish a method for simultaneous determination of rutin, quercetin and nuciferine in Heye granule. METHODS:HPLC was performed on the column of Hypersil ODS2 with mobile phase of acetonitrile-water(containing 0.3% phosphoric acid and 0.4% triethylamine)(gradient elution) at a flow rate of 1.0 ml/min, the detection wavelength was 256 nm, the column temperature was 25 ℃, and the injection volume was 10 μl. RESULTS: The linear range was 0.012-0.240 μg for rutin(r=0.999 9), 0.010 4-0.208 μg for quercetin (r=0.999 9) and 0.015-0.300 μg for nuciferine(r=0.999 9);RSDs of precision,stability and reproducibility tests were lower than 2.0%;recoveries were 98.5%-101.3%(RSD=1.1%,n=6),99.1%-101.6%(RSD=1.0%,n=6) and 98.9%-101.7%(RSD=1.2%,n=6). CONCLUSIONS:The method is simple, accurate and reliable, and can provide reference for quality control of Heye granule.
