Abstract：The twelve trace elements in the pagoda flower, including K, Na, Ca, Mg, Pb, Cd, Cu, Mn, Co, Zn, Cr and Fe were determined simultaneously by FAAS. The relative standard deviation of the method is 0.07%-2.31%, and the recovery is 97.0%-107.0%. The analytical results were satisfactory. The results showed that there were comparatively rich metal elements in the pagoda flower. Proportions of the twelve elements are in the order that K＞Ca＞Mg＞Na＞Fe＞Zn＞Cu＞Mn＞Co＞Pb＞Cr＞Cd. It implied that the nutritive value of the pagoda flower is high.
