Abstract: Seven mineral elements (Fe, Zn, Cu, Mn, Mg, K and Ca) in leaves and barks of Eucommia ulmoides Oliv.from different places of Zhangjiajie were determined by FAAS (Flame Atomic Absorption Spectrophotometer). The results showed that the leaves and barks of E. ulmoides Oliv.were rich in mineral elements. The order of these mineral element contents in leaves was Mg >K >Ca >Zn >Fe >Mn≥Cu, while in the barks Mg >Ca >K >Fe >Zn >Mn≥Cu. The contents of all the mineral elements in leaves and barks were normally distributed by K-S (Kolmogorov-Smirnov) test. It was significantly different for the contents of Fe, Mn and Mg in leaves by LSD (Least Significant Difference) test. It was the same with the contents of Fe, Mn and K in barks. The results could provide the theoretical basis for the difference in pharmacological activity and quality of leaves and barks of E. ulmoides Oliv. from different places.

Key words: Eucommia ulmoides Oliv., leaves, barks, mineral elements, K-S test, LSD
