title: [Analysis of vitamins and inorganic elements in the water extracts of Radix Changii].
abstract: OBJECTIVE
  To study the material basis of the tonifying effect of Radix Changii by observing its contents of nutrient elements.
  
  
  METHODS
  The contents of vitamins in Radix Changii and inorganic elements in the water extracts of it were tested by high performance liquid chromatography, fluorescence spectrophotography and scanning electron microanalysis.
  
  
  RESULTS
  Radix Changii contains fat-soluble vitamins E and K 259.2 and 64.1 microg/kg respectively, and water-soluble vitamins C, B1 and B2 78.5, 0.6 and 0.7 mg/kg respectively. Its decoction contains abundant potassium and calcium ions.
  
  
  CONCLUSIONS
  Radix Changii is rich in elements necessary for human body. It has the material basis for tonification.
