| Abstract: | The macro and trace elements(iron,zinc,copper,Manganese,calcium,potassium, sodium and magnesium)in radix gentianae macrophyllae from Gentiana macrophylla Pall.,G. straminea Maxim.,G.crassicaulis Duthie ex Burk.and G.dahurica Fisch.were determined by FAAS. The contents of macro and trace elements from 4 species were quite different.The concentrations of Ca,Mg,K,Zn and Mn were higher in the root of Gentiana macrophylla Pall.,which mainly grows in Shaanxi province. |
