The contents of K ,Na ,Ga ,Mg ,Zn ,Fe ,Mn and Cu from different parts of Trillum Kamtschaticum Pall.were texted using flame atomic absorption.The results showed that these eight inorganic elements localized in different parts.There were higher content of K and Ca in stems and leaves the average contents were 2.17% and 2.16% ,respectively ,compared to other parts.The contents of Mgand Fe were 0.28% and 0.13% in stems and leaves ,respectively.While the contents of Na ,Zn ,Mn ,Cu were relatively low.Each element in the roots ,stems and leaves had a similar distribution.Contents of K ,Ca were higherst ,the average value were 0.67 and 0.26% ,respectively ,followed by Mg ,Fe ,the aver-age value were 0.108% and 0.107% ,respectively.While the levels of inorganic elements was significantly different in root from in stems and leaves.The contents of Zn ,Ca and Fe in roots were increased to 31.09% ,16.29% and 14.94% ,respectively.the biggest changes in the stems and leaves are Na ,decrease 51.33% ,Mg ,Fe and Mn ,respectively decrease 44.24% ,44.23% and 43.93%.With the delay of harvest time , the contents of inorganic elements in stems and leaves showed a downward trend ,while a rising trend was found in roots.
