硒是人体必须的微量元素,其特殊的生理功能,营养和解毒,可能是含硒的蛋白质或酶在起作用,其机理尚待深入研究。本法采用程序升温,测定西洋参及其茎叶的硒含量,对样品的处理,色谱测定条件等进行研究。本方法最小检测达到1×10~(-10)g。实验部分1 仪器和试剂GC—15A 日本岛津气相色谱仪恒温烘箱硝酸、盐酸、甲苯等试剂均为优级纯。 Selenium is a necessary trace element for the human body. Its special physiological functions, nutrition and detoxification may be due to selenium-containing proteins or enzymes. The mechanism remains to be studied. This method uses a program to raise the temperature, determine the selenium content of American ginseng and its stems and leaves, the sample processing, chromatographic conditions and other studies. The minimum detection of this method reaches 1×10 -10 g. Experimental part 1 Instruments and reagents GC-15A Japan Shimadzu gas chromatograph constant temperature oven Nitric acid, hydrochloric acid, toluene and other reagents are all grade pure.
