Abstract
[ Objective ] The study aimed to analyze the relationship between the microelements and the efficacy of Senecio scandens Ham and provide some theoretical basis for elucidating its pharmacological function. [ Method] 7 kinds of microelements including K, Ca, Mg, Fe, Na, Zn and Mn in S. Scandens in Hanzhong area were detected by the microwave digestion-FAAS. [ Result ] The method of microwave digestion was easy, rapid and accuracy in the operation, and had advantages of complete sample digestion, low blank value and less environmental pollution. The FAAS method had good selectivity and high accuracy, with the recovery of 98.2% ~ 102.9%. The sample determination showed that 5. Scandens in Hanzhong area was rich in 4 kinds of microelements including K, Ca, Mg and Fe. [ Conclusion] The method of microwave digestion and FAAS could be used to determin the microelements in 5. Scandens in Hanzhong area.关键词
