title: [Studies on extraction technology of total flavonoids from flower of Eriobotrya japonica].
abstract: OBJECTIVE
  To study the optimum extraction technology of total flavonoids from Flower of Eriobotrya japonica.
  
  
  METHODS
  To screen the best extraction technology by single-factor and orthogonal experiment according to the content of total flavonoids.
  
  
  RESULTS
  The optimum conditions were as follows: we extracted three times at 60 degrees C, each time for 1 h and the ratio of raw materials and solution was 1:10.
  
  
  CONCLUSIONS
  The extracting method is fit for the extraction of total flavonoids from Flower of Eriobotrya japonica. It can also provide a scientific basis for manufacture.
