title: [Study on the preparation of rapid-dissoluted EGb droppills].
abstract: OBJECTIVE
  To study the formulation and technique of preparation of rapid-dissoluted EGb (Extract of Ginkgo biloba) droppills.
  
  
  METHODS
  Taking the dissolution percentage of total flavonoids in EGb and weight variation as index, the formulation and technique of EGb droppills were optimized by the orthogonal experiment.
  
  
  RESULTS
  T50 was 3.62 min and mean weight variation was 2.80%.
  
  
  CONCLUSIONS
  Rapid-dissoluted EGb droppills can increase the dissoluting rate distinctly and reach the purpose of preparation.
