摘要

目的:建立高效液相色谱法测定大鼠血浆中苍耳亭的浓度。方法:采用高效液相色谱法

色谱柱为Hypersil ODS2柱（250 mm×4.6 mm

5μm）

流动相为甲醇-水（V∶V=52∶48）

流速为1.0 ml/min

检测波长为278 nm

柱温为25℃。血浆样品经二氯甲烷萃取富集

10μl进样检测。结果:苍耳亭质量浓度在0.1～10μg/ml（R

=0.999 7）范围内呈现良好的线性关系

定量下限为0.1μg/ml。苍耳亭低、中及高浓度的提取回收率分别为89.19%、83.56%及96.72%

日内和日间精密度分别≤5.47%和8.65%。结论:本方法灵敏快速简单

适用于体内苍耳亭的浓度分析

为药动学研究提供方法依据。

Abstract

OBJECTIVE:To establish the high performance liquid chromatography（HPLC） method for determination of concentration of xanthine in rat plasma.METHODS:HPLC methods was adopted with Hypersil ODS2 column（250 mm × 4.6 mm

5 μm）.The mobile phase was methanol-water（V:V=52:48）

the flow rate was1.0 ml/min

the detection wavelength was 278 nm

and the column temperature was 25 ℃.The plasma samples were extracted and enriched with dichloromethane

and 10 μl injection was used for detection.RESULTS:The calibration curve of xanthatin in plasma showed good linear correlation in the range from 0.1 to 10 μg/ml（R

=0.999 7） and the lower limit of concentration was 0.1 μg/ml.The extraction recovery rates of low

medium and high concentration of Xanthatin was respectively 89.19%

83.56% and 96.72%

and the intra-day and inter-day precision was respectively≤5.47% and 8.65%.CONCLUSIONS:This method is sensitive

rapid and simple

and is suitable for the analysis of the concentration of xanthine in vivo

and provides basis for pharmacokinetic research.
