黄芪及其水煎液中Cu、Mn、Zn、Fe、Se的测定和浸出率研究

Study on Extracting Rates and Determination of Cu,Mn,Zn,Fe, Se in Huangqi and Its Water Decocted Solution

用原子吸收法对黄芪及其水煎液中的Cu、Mn、Zn、Fe进行了测定 ,用紫外分光光度法测定了其中的Se ,从而得出各元素的浸出率。结果表明五种元素的浸出率为 :Cu >Zn >Mn >Se >Fe。

The concentrations of elements Cu,Mn,Zn,Fe in Huangqi and its water decocted solution have been detemined by AAS method,while Se by UV method.The extracting rates of five elements showed Cu>Zn>Mn>Se>Fe.
