以无机元素为特征指标的太和贡椿指纹图谱研究

Study on Fingerprint of Toona sinensis in Taihe for Taking Inorganic Elements as Characteristic Indexes

以4种常量元素和4种微量元素为特征指标,研究了其基本含量,在国标方法的基础上进行了改进,建立了原子吸收分光光度法测定K,Na,Ca,Mg,Fe,Zn,Mn,Cu的测定方法,指出太和贡椿中矿物元素含量丰度依次为K,Na,Ca,Zn,Fe,Mg,Mn,Cu;并与其他产地的香椿进行了差异性分析,为太和贡椿建立以矿物元素为参数的特征指纹图谱,提供了借鉴。

In this study,four major elements and four trace elements were taken as the characteristic indexes,and their basic contents were studied.Based on the national standard method,an improved method for the determination of K,Na,Ca,Mg,Fe,Zn,Mn,Cu by atomic absorption spectrophotometry was established.It was pointed out that the abundance of mineral elements in Taihe tribute toon was K,Na,Ca,Zn,Fe,Mg,Mn,Cu,and compared with the Chinese toon produced in other places,it provides a reference for establishing the characteristic fingerprint of Chinese toon in Taihe with mineral elements as parameters.
