title: [Determination of germanium in aloe vera by spectrophotometric method].
abstract: OBJECTIVE
  To analyze the organic germanium in aloe vera from different localities.
  
  
  METHODS
  The method was based on germanium forms a stable complex with phenylfluorone in the acidified solution and CTMAB as solubilization agent. The contents of the organic germanium in Aloe vera from different localities were determined by spectrophotometric methods.
  
  
  RESULTS
  The linear range of determination is 0-0.7 microg/ml. The recovery is 98.1%-99.0% and the coefficient of variation is 1.8%.
