[Objective]To study the optimum extraction process of FRUCTUS SCHISANDRAE CHINENSIS in Zhenzaoanshen capsule.[Method] Taking the yield of schizandrin as index,L 9(3 4) orthogonal test designed with four factors like ethanol concentration,extraction time,solid-liquid ratio and extraction times was conducted to select the optimum extraction process for FRUCTUS SCHISANDRAE CHINENSIS.[Result]The optimum extracting process for FRUCTUS SCHISANDRAE CHINENSIS was boiled in 10 times water [solid-liquid ratio = 1:10(g /ml) ] and refluxed for 3 times,1.5 h every time.[Conclusion] This extraction process was a simple and feasible method that was suitable for extracting FRUCTUS SCHISANDRAE CHINENSIS in Zhenzaoanshen capsule.
