To provide a scientific basis for the research and development of Capparis spinosa L and determine the content of trace elements abundant in seeds. Determination of eight predictive trace elements, Cu, Zn, Fe, Mn, Ca, K, Mg and Cr, was carried out by ICP-AES. Among the determined eight predictive trace elements, the contents of Fe， Zn， Cu and Cr are the highest. Capparis spinosa L is worth researching deeply not only Chemically but also pharmacologically as a Chinese Uygur herb.
