title: [Extraction of ginkgolides from Ginkgo biloba].
abstract: OBJECTIVE
  To establish the technology for extraction of ginkgolides from Ginkgo Biloba with alcohol-water.
  
  
  METHODS
  The parameters such as alcohol concentration, pH of extracting solution, ratio of dosage liquor, temperature and time, the extraction of ginkgolides from G. biloba was investigated, and its parameters were optimized.
  
  
  RESULTS
  The optimized parameters were alcohol concentration 30%, extracting temperature 50 degrees C, extracting time 2 h, pH 5 solid-liquid ratio 1:15.
  
  
  CONCLUSIONS
  This method has the merits of low cost and simple operation.
