Study on the elements and element speciation in the Schisandra chinensis extractThe seven elements,Mg,Fe,Mn,

Cu,Ni,Cr and Co,in Schisandra chinensis extract were extracted based on traditional analytical Flowchart program 

and separated into water-soluble state and suspension state by 0.45 μm membrance filter.Water-soluble state was

divided into organic state and inorganic state by 101 macroporous adsorption resin.


The elements were detected by inductively coupled plasma mass-spectrometry (ICP-MS).The veracity of analytical 

results were validated with CRM's under the same conditions.The results show ertractive rates of the seven elements 

were in the range of 24.34% ~74.62%,and immerse-residue ratio in 0.476 ~1.401,Adsorption ratio of suspension 

state was in the range 21.79% ~85.12%.The content of elements was higher in the residue,the residue also had 

some use value.The recoveries of the elements were ranged from 94.36%~107.12% and relative standard deviations 

were less than 2.98%.
