摘要
随着植物激素的滥用及使用不当导致的食品安全问题逐渐增多,加强食品中植物激素的痕量检测显得日益重要。本研究制备了具有两亲性的聚(甲基丙烯酸苄基酯-甲基丙烯酸)胶束,成功地将5种植物激素分离,建立了一种植物激素痕量检测的聚合物胶束毛细管电动色谱方法,本方法高效、快速、重现性好。经过优化,得到了最佳色谱条件:2 g/L聚合物胶束,50 mmol/L Na OH-H3BO3缓冲液(p H 9.2);运行电压15 k V。采用此方法分析实际样生根粉溶液,成功检测到萘乙酸。
With the increasing number of food safety problems caused by the abusing and misusing of plant hormones,it will be increasingly important to strengthen the trace detection of plant hormones in foods. In this study,benzyl methacrylate-methyl methacrylate-based amphiphilic polymer micelles were prepared,and a method for trace determination of five plant hormones was established by using these micelles. This method was rapid,sensitive and reproducible. Through optimization,the best experimental conditions were obtained as follows： 2 g / L polymer micelles,50 mmol / L Na OH-H3BO3buffer（ pH 9. 2）,15 k V running voltage.Based on this novel method,naphthalene acetic acid in the solution of rooting powder was determined.
