[Analysis Characteristics of Inorganic Elements in Different Organs of Hedysarum polybotrys in Different Growing Variation].

Objective: To study the characteristics of inorganic elements in different organs of Hedysarum polybotrys in different growing variation, including root, rhizome, leaf, flower and fruit.

Methods: The content of 13 inorganic elements in different organs were detected by using flame atomic absorption method, and then the characteristics of inorganic elements in different organs of Hedysarum polybotrys in different growing variation were analyzed.

Results: There were abundant inorganic elements in root, rhizome, leaf, flower and fruit, the change in the contents of inorganic elements at different growing variation related to the season. The contents of Fe,Cu,Ca,Mn,Zn, Mg, Cr, Co, Na, Li,Ni and K were regularly changed with the change of growing variation, and Cd was not deteced. The content of Cu and Ca order was leaf > root > rhizome, and the content of Mn at leaf was higher than that at other organs during June to October.

Conclusion: The results provide scientific basis for the harvest time of Hedysari Radix and the development of non-medicinal portions.
