To analyze the organic germanium in aloe vera from different localities. 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. 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%.
