title: [Analyses on the trace elements of soils in geo-authentic and non-authentic production areas of Flos lonicearae].
abstract: OBJECTIVE
  To analyse the trace elements presented in the same germplasm of Flos Lonicerae with the soil in different producing areas of crude drugs and to investigate, the relationship between the trace elements and the characteristics of the geo-authentic Flos Lonicerae in the soil and crude drugs.
  
  
  METHODS
  The analyses on the trace elements of soil and crude drugs were made by ICP-AES.
  
  
  RESULTS
  The contents of Sr, K, Na, Mg and Ca were higher in the geo-authentic areas, and the contents of Ca, Sr and Fe were higher, but the Cr and Pb were lower in the geo-authentic Flos Lonicerae. The geo-authentic crude drugs had a strong tendency to accumulate P and Cu.
  
  
  CONCLUSIONS
  There are no direct relationship between the concentrations of trace elements in Flos Lonicerae and those in their corresponding soil. There are good relationship between the absorption and accumulation of Ca and Cr, Co, Na and Fe; Zn and Co, Cr, Mn; Na and Co; Mg and Mn.
