title: [Application of genetic algorithm in blending technology for extractions of Cortex Fraxini].
abstract: OBJECTIVE
  To explore the feasibility of genetic algorithm (GA) on multiple objective blending technology for extractions of Cortex Fraxini.
  
  
  METHODS
  According to that the optimization objective was the combination of fingerprint similarity and the root-mean-square error of multiple key constituents, a new multiple objective optimization model of 10 batches extractions of Cortex Fraxini was built. The blending coefficient was obtained by genetic algorithm. The quality of 10 batches extractions of Cortex Fraxini that after blending was evaluated with the finger print similarity and root-mean-square error as indexes.
  
  
  RESULTS
  The quality of 10 batches extractions of Cortex Fraxini that after blending was well improved. Comparing with the fingerprint of the control sample, the similarity was up, but the degree of variation is down. The relative deviation of the key constituents was less than 10%.
  
  
  CONCLUSIONS
  It is proved that genetic algorithm works well on multiple objective blending technology for extractions of Cortex Fraxini. This method can be a reference to control the quality of extractions of Cortex Fraxini. Genetic algorithm in blending technology for extractions of Chinese medicines is advisable.
