市售散装抗感冒凉茶中对乙酰氨基酚的快捷检测方法研究

Rapid Detection of Acetaminophen in Bulk Cold Herbal Tea

目的：建立市售散装抗感冒凉茶中非法添加对乙酰氨基酚的薄层液相色谱（ TLC ）快捷筛查检测方法。方法利用薄层液相色谱（ TLC）手段建立市售散装抗感冒凉茶中非法添加对乙酰氨基酚的快捷筛查检测方法，对影响薄层色谱结果的影响因素湿度、温度、展开距离、薄层色谱预制板来源等进行优化。结果在温度32℃，湿度28％～32％，分别吸取凉茶样品，对乙酰氨基酚对照品3μL以条状点于规格为5cm×10cm的青岛海洋GF254薄层色谱板上进行展开为最优条件。结论该优化方法快速灵敏，操作简便，可用于市售散装凉茶中非法添加对乙酰氨基酚化学品的快捷检测。

OBJECTIVE To establish a method of TLC for rapidly detecting whether there are illegal added ac-etaminophen in cold herbal tea.METHODS Doing a research about the factors of TLC,which including humidity, temperature,TLC panels and so on.RESULTS Under the optimum condition of T=32℃,RH：28%～33%,3μL of bulk cold herbal tea samples and acetaminophen reference were drawn to strip points on specifications for 5 cm ×10cm of Qingdao Ocean GF254 TLC plates.CONCLUSION The method is rapid,easy to operate,and specific.
