title: [Research on preparation of Shandantong sustained-release tablets].
abstract: OBJECTIVE
  To optimize the preparation of Shandantong sustained-release tablets.
  
  
  METHODS
  We used the orthogonal experiment to optimize the preparation and determined the contents of Shanzha total flavonoids and tanshinone. Involved technology and hydrophilicity skeleton materials were adopted to prepare the sustained-release tablets.
  
  
  RESULTS
  The best extracted progress of Shanzha total flavonoids and tanshinone were A2B2C1 and A3B1C2, respectively. The hydrophilicity skeleton materials were gel HPMC and acrylic resin.
  
  
  CONCLUSIONS
  The concentration of alcohol and percolated speed are significant factors on the extracted efficacy by analysis of variance. The preparation and prescription of this sustained-release tablet is reasonable.
