Determination of the contents of metallic elements in Polygonatum odoratum cultivated in Anhui province / 中国基层医药

ABSTRACT

Objective The purpose of this study was to determine the contents of metallic elements of K,Ca,Mg,Zn,Mn,Cu and Fe in Polygonatum odoratum cultivated in Anhui province.Methods Atomic absorption spectrophotometry was utilized to determine the contents of metallic elements.Results The average contents of K,Ca,Mg,Zn,Mn,Cu and Fe were 12.7047mg/g,1.59083mg/g,0.55495mg/g,0.02034mg/g,0.01839mg/g,0.00664mg/g and 0.11791mg/g,respectively.The data were analyzed by t test.There was no significant difference between groups of each metallic element.Conclusion The contents of metallic elements of K,Ca,Mg,Mn and Fe incultivated Polygonatum odoratum were influenced easily by the culture base.
