Abstract

This study presents a combination of High Performance Liquid Chromatography (HPLC) and ultraviolet (UV) detection that provides the quantification of agnuside in human plasma specimens. Reverse-phase chromatographic separation was carried out with C18 column (150 mm × 4.6 mm × 5 μm), at 25°C with isocratic elution of the mobile phase containing methanol: 0.1% formic acid (35:65 v/v) at 0.6 mL/min flow rate. Experiments were carried out at a wavelength of 258 nm. The retention time of the analyte is 9.70 ± 0.01 min. The developed technique was validated based on the International Conference on Harmonization guideline. The correlation coefficient of the technique was 0.9915, and the calibration range was 5-125 μg/mL. The recovery value of the proposed method was found to be 101.4%, and the precision of the method was calculated as 6.35 with the highest RSD% value. A pharmacokinetic study was performed by administering agnuside to a healthy volunteer.

新型高效液相色谱法定量测定人血浆中agn甙及药代动力学研究。

本研究提出了一种高效液相色谱（HPLC）和紫外（UV）检测相结合的方法，可以定量测定人血浆标本中的agnuside。采用C18色谱柱（150 mm × 4.6 mm × 5 μm）进行反相色谱分离，在25℃条件下，流动相为甲醇：0.1%甲酸（35:65 v/v），流速0.6 mL/min，等密度洗脱。实验在波长258 nm处进行。分析物的保留时间为9.70±0.01 min。根据国际协调会议准则对该技术进行了验证。该技术的相关系数为0.9915，校准范围为5 ~ 125 μg/mL。该方法的回收率为101.4%，精密度为6.35，RSD%值最高。通过给健康志愿者服用agnuside进行了药代动力学研究。

期刊介绍： The Journal of Chromatographic Science is devoted to the dissemination of information concerning all methods of chromatographic analysis. The standard manuscript is a description of recent original research that covers any or all phases of a specific separation problem, principle, or method. Manuscripts which have a high degree of novelty and fundamental significance to the field of separation science are particularly encouraged. It is expected the authors will clearly state in the Introduction how their method compares in some markedly new and improved way to previous published related methods. Analytical performance characteristics of new methods including sensitivity, tested limits of detection or quantification, accuracy, precision, and specificity should be provided. Manuscripts which describe a straightforward extension of a known analytical method or an application to a previously analyzed and/or uncomplicated sample matrix will not normally be reviewed favorably. Manuscripts in which mass spectrometry is the dominant analytical method and chromatography is of marked secondary importance may be declined.
