Abstract
    [Objective] To explore the optimum extracting conditions for compound Yishen (tonifying the kidney) soft capsule.[Methods] The orthogonal design was taken for the optimization of ethyl alcohol and percolate speed with the content of loganin determined by RP-HPLC.[Results] The optimum extracting conditions were A3B3C1,that is percolating with 70% EtoH,the percolate speed with 3.0 mL/(min·kg),collecting the amount of percolate 8 times.[Conclusions] The optimum extracting procedure is reasonable and stable.
