篇名: UPLC法同时测定清眩片中欧前胡素和异欧前胡素的含量
TITLE:
摘要: 目的:建立同时测定清眩片中欧前胡素和异欧前胡素含量的方法。方法:采用超高效液相色谱法。色谱柱为ACQUITY UPLC BEH C18,流动相为甲醇-水(梯度洗脱),流速为0.3 ml/min,检测波长为248 nm,柱温为30 ℃,进样量为3 μl。结果: 欧前胡素和异欧前胡素的检测质量浓度线性范围分别为1.305~13.05、1.096~10.96 μg/ml(r均为0.999 9);精密度、稳定性、重复性试验的RSD<1%;加样回收率分别为 97.45%~100.10%(RSD=1.00%,n=9)、98.33%~101.20%(RSD=1.01%,n=9)。结论: 该方法准确、快速、可靠,可用于同时测定清眩片中欧前胡素和异欧前胡素的含量。
ABSTRACT: OBJECTIVE: To establish a method for the simultaneous determination of imperatorin and isoimperatorin in Qingxuan tablet. METHODS: UPLC was performed on the column of ACQUITY UPLC BEH C18 with mobile phase of methanol-water (gradient elution) at a flow rate of 0.3 ml/min, the detection wavelength was 248 nm, column temperature was 30 ℃, and the injection volume was 3 μl. RESULTS: The linear range was 1.305-13.05 μg/ml for imperatorin (r=0.999 9) and 1.096-10.96 μg/ml for isoimperatorin(r=0.999 9); RSDs of precision, stability and reproducibility tests were lower than 1%; recoveries were 97.45%-100.10% (RSD=1.00%,n=9) and 98.33%-101.20% (RSD=1.01%,n=9), respectively. CONCLUSIONS: The method is accurate, fast and reliable, and can be used for the simultaneous determination of imperatorin and isoimperatorin in Qingxuan tablet.
