ABSTRACT

<p><b>OBJECTIVE</b>To optimize the combined extraction methods of Fructus Schisandrae Chinensis and Fructus Ligustri Lucidi.</p><p><b>METHOD</b>The extraction effects of three processes (SFE CO2, alcohol-extraction, water-extraction) were compared by the contents of deoxyschizandrin, the dried extraction yield and production feasibility.</p><p><b>RESULT</b>The method of alcohol-extraction was the best of the three methods, and the extraction conditions were optimized by orthogonal design as follows sixfold 90% alcohol for two times and each for one hour.</p><p><b>CONCLUSION</b>The extraction method is steady and feasible, which can be used for reference for the extraction process of Fructus Schisandrae Chinensis and Fructus Ligustri Lucidi.</p>
