[Determination of inorganic elements in Elsholtzia bodinieri Vaniot from gansu by microwave digestion ICP-AES].
In the present paper, orthogonal test and square error analysis were applied to the determination of inorganic elements in the aerial part of E. bodinieri V. such as K, Na, Ca, Ba, Pb, Zn, Mn, Cu, Mg, Fe and Al by microwave digestion ICP-AES technique. The method is simple, rapid, and features of high sensitivity, good accuracy and simultaneous determination of many elements. Its recovery ratio obtained by standard addition method ranged from 93.2% to 104.1%, and its RSD (n=5) was lower than 3.20%. The results showed that this plant has rich inorganic elements, which are essential to human health. The result provides a theoretical basis for investigating the correlation of element content and the effect of medicine in E. bodinieri V.
