[Object] The aim was to determine the contents of Cu, Fe, Zn, Mn in different parts of Lippia nodiflora and explore the development and 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 contained abundant Cu, Fe, Zn, Mn elements, among which Fe ranked first. [Conclusion] The contents of Fe, Mn, Zn in root, stem and leaf of L. nodiflora are higher, so it is appropriate for all herbs used for medicine, which is consistent with the formulation of traditional Chinese medicine encyclopaedia.
