摘要
蜂胶具有抗菌、抑制病毒、调节机体免疫力、抵抗类毒素以及清除氧自由基等临床药理作用,其中所含有的黄酮化合物是一类重要的中药药效成分,可有效清除体内自由基。关于蜂胶中黄酮类化合物的测定迄今未见有理想的方法。文章在碘催化的鲁米诺电化学发光的基础上,利用黄酮化合物对碘自由基的清除作用,研究了一种电化学发光猝灭法测定蜂胶中黄酮总效价的分析方法,该方法简便快捷、灵敏度高,可望用于蜂胶产品的质量鉴定。
Propolis is a kind of quality health foodstuff containing flavonoids, which is an important clinical effective component in many Chinese traditional medicines. The flavonoids could be used to reduce or clear free radicals, which manifests its medical functions. But there are no satisfactory methods to analyze the content of flavonoids in propolis. This paper reports a new method to determine the total effective value of flavonoids in propolis based on quenched effect for iodide-catalyzed electrochemiluminescence of luminol. It is a sensitive and simple method and might be a probable approach to examining the quality of propolis products.
