[Objective] To analyze the contents of 9 inorganic elements contents in wild Salsola collina Pall.,Polygonum aviculare L.,and Artemisia argyi in Tianjin City,so as to provide scientific basis for the research on their efficacy.[Method] Salsola collina Pall.,Polygonum aviculare L.,and Artemisia argyi were treated by wet method.And 9 inorganic elements(Ca,Mg,Fe,Cu,Zn,K,Pb,Na and Mn) were determined by FAAS.[Result] In the 3 traditional Chinese medicines,Ca content ranged from 6 440.49 to 9 364.01 μg/g,Cu from 13.19 to 31.14 μg/g,Mg from 5 156.66 to 10 423.99 μg/g,Mn from 63.71 to 108.03 μg/g,K from 18 262.22 to 24 836.81 μg/g,Na from 109.92 to 6 329.75 μg/g,Zn from 67.07 to 90.94 μg/g,and Fe from 969.32 to 2 147.52 μg/g.A certain amount of Pb was detected in all the three medicines.Polygonum aviculare L.had relatively low contents of inorganic elements,while Artemisia argyi had relatively high contents.[Conclusion] The method was accurate,stable,easy and rapid.
[Objective] To analyze the contents of 9 inorganic elements contents in wild Salsola collina Pall., Polygonum aviculare L., and Artemisia argyi in Tianjin City, so as to provide scientific basis for the research on their efficacy. [Method] Salsola collina Pall ., Polygonum aviculare L., and Artemisia argyi were treated by wet method. And 9 inorganic elements (Ca, Mg, Fe, Cu, Zn, K, Pb, Na and Mn) were determined by FAAS. Traditional Chinese medicines, Ca content ranged from 6 440.49 to 9 364.01 μg / g, Cu from 13.19 to 31.14 μg / g, Mg from 5 156.66 to 10 423.99 μg / g, Mn from 63.71 to 108.03 μg / g, K from 18 262.22 to 24 836.81 μg / g, Na from 109.92 to 6 329.75 μg / g, Zn from 67.07 to 90.94 μg / g, and Fe from 969.32 to 2 147.52 μg / g A certain amount of Pb was detected in all the three medicines. Polygonum aviculare L.had relatively low contents of inorganic elements, while Artemisia argyi had relatively high contents. [Conclusion] The method was accurate, stable, easy and rapid.
