| 中文摘要: |
| 建立一种防老剂N2-苯基吡啶-2，5-二胺的高效液相色谱定量分析方法。使用C18色谱柱，流动相为甲醇/纯水（体积比为70/30），流速为1.0 mL·min-1，柱温为35 ℃，在254 nm波长下进行检测。结果表明，N2-苯基吡啶-2，5-二胺的质量浓度与峰面积之间呈现出良好的线性相关性，其相关因数为0.999 7，含量测试结果的标准偏差为0.23%，回收率为99.11%～100.79%。本方法操作简单，结果准确，重复性良好，适用于N2-苯基吡啶-2，5-二胺的定量分析。 |
| 英文摘要: |
| A high-performance liquid chromatography quantitative analysis method for antioxidant 2-N-phenylpyridine-2，5-diamine was established.Using C18 chromatography column，the mobile phase of methanol/pure water（volume ratio of 70/30） at a flow rate of 1.0 mL·min-1，and column temperature of 35 ℃，the detection was performed at a wavelength of 254 nm.The results showed that a good linear correlation between the mass concentration and peak area of 2-N-phenylpyridine-2，5-diamine，with correlation coefficient of 0.999 7，standard deviation of 0.23% for the mass fraction test，and a recovery rate of 99.11% to 100.79%.The method was simple to operate，accurate in results，and had good repeatability，making it suitable for quantitative analysis of 2-N-phenylpyridine-2，5-diamine. |
