摘要

目的:建立一种测定核桃青皮中胡桃醌含量的高效液相色谱法

为实现核桃青皮的合理开发利用提供依据。方法:采用高效液相色谱法测定了核桃鲜皮和冷冻青皮中的胡桃醌含量

对此方法进行了方法学评价。结果:胡桃醌对照品在0.01～8.00μg线性相关良好（r=0.999 3）;检出限为0.195 ng;平均回收率为98.67%（n=6）

RSD<2.03%;精密度RSD<0.58%（n=7）。新鲜核桃青皮中胡桃醌的含量为1.66 mg·g-1

冷冻青皮含量为1.54 mg·g-1。结论:该方法样品前处理简单、分析快速

重复性好

准确度和精密度高

适合胡桃醌类样品的分析测定。

Abstract

Objective:To establish an HPLC method for determining the content of juglone in the husk of walnut

to provide the basis for the resource exploitation and utilization of juglone.Method:The method was evaluated by HPLC in methodology and the samples which were fresh and stored in freeze temperature were determined.Result: This HPLC methord have a simple preparation for popularization easily.The results indicate that this certain method had good linear relationship under the condition that the content was between 0.01 μg and 8 μg（r=0.999 3） and the detection limit of this method was 0.195 ng.The average recovery was 98.67%（n=6）

RSD was below 2.03%;the RSD of the indicated accuracy was below 0.58%（n=7）.Juglone in the husk of fresh walnut was 1.66 mg·g-1 and another sample was 1.54 mg·g-1 which was stored in freeze temperature.Conclusion: This certain method is simple

fast and reproducible with a high accuracy and precision

which fit for the analysis of juglone.
