[Extracting techniques for optimizing zi shen granule by orthogonal text].
OBJECTIVE: To optimize the extracting techniques for Zi Shen Granule. METHODS: By taking the rate of extractum and the total of anthraquinone as the indexes components, the extraction techniques were optimized for Zi Shen Granule through L9 (3) 4 orthogonal text. RESULTS: The best condition is twice extraction by 2h or 1.5 h, to add octuple water. Then the water solution was concentrated to relative concentration 1.10, and adds ethanol to 70% alcohol Concentration,then stewing 24h. CONCLUSION: The optemized extraction technique is rational and jarless and ideal for mass production.
