报道了一种测定辛醇/水分配系数对数P(o/w)的高效液相色谱方法。这种自动对数P(o/w)测量(ALPM)绕过了摇瓶方法的许多固有困难，但提供了高度的重复性和与摇瓶结果良好的总体相关性。可以确定许多结构不同的化学品的分配系数，范围从∼0到∼8 logP(o/w)单位；但是，两性离子化合物的值无法获得。与其他高效液相或摇瓶程序相比，ALPM的其他优点包括更低的成本和更大的安全性。详细讨论了影响该方法的色谱条件(即流速和温度)和变量(即柱长和溶剂组成)。ALPM还可应用于高效液相色谱柱的质量控制、定性-定量分析以及计算机控制方法的开发和分析。
A high‐performance liquid‐chromatographic (HPLC) procedure is reported for estimation of the logarithm of the octanol/water partition coefficient, log P(o/w). This automated log P(o/w) measurement (ALPM) circumvents many inherent difficulties with the shake‐flask method, yet gives high reproducibility and excellent overall correlation with shake‐flask results. Partition coefficients for numerous structurally diverse chemicals, ranging from ∼0 to ∼8 log P(o/w) units, can be determined; however, values for zwitterionic compounds cannot be obtained. Additional advantages of ALPM include lower cost and greater safety when compared with other HPLC or shake‐flask procedures. Chromatographic conditions (i.e., flow rate and temperature) and variables (i.e, column length and solvent composition) affecting this method are discussed in detail. ALPM may also find application in quality control of HPLC columns, qualitative‐quantitative analysis, and in computer‐controlled method development and analysis.
