金银花道地与非道地产区土壤微量元素分析

Analyses on the Trace Elements of Soils in Geo-authentic and Non-authentic Production Areas of Flos Lonicearae

目的 :通过分析同一种质金银花在不同产区土壤与药材中微量元素的含量 ,探讨金银花药材道地性与土壤微量元素的关系。方法 :应用电感耦合等离子体光电直读光谱仪分别对金银花药材和土壤样品进行微量元素含量分析。结果 :道地产区土壤中锶、钾、钠、镁、和钙的含量高 ,道地药材金银花中钙、锶和铁的含量高 ,铬和铅的含量低 ,对铜和磷的富集能力强。结论 :金银花药材与土壤中的微量元素含量无直接相关 ,但金银花对钙和铬、钴、钠、猴 ;锌和钴、铬、锰 ;钠和钴 ;

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. Method: The analyses on the trace elements of soil and crude drugs were made by ICP AES. Result: 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. Conclusion: 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.
