| Abstract: | Objective] The aim was to determine the contents of Cu,Fe,Zn,Mn in different parts of Lippia nodiflora and explore development utilization value of L. nodiflora. Method] By using mixed acid which contains nitric acid and perchloric acid to digest samples and by atomic absorption spectrometry,four kinds of trace elements Cu,Fe,Zn,Mn in root,stem,leaf of L. nodiflora were determined. Result]The results showed that each part of L. nodiflora contains abundant Cu,Fe,Zn,Mn elements,among which,Fe ranges first.... |
