OBJECTIVE To optimize the extracting technology of Salviae miltiorrhiza. METHODS The contents of tanshinone ⅡA and tanshinol are regarded as target to optimize the extracting method by orthogonal test and single factor test. RESULTS The optimized extracting technological conditions were as follows： alcohol concentration 950 mL/L, extraction time 90 min, the ratio of solvent to material 6 ： 1; the residuum was extracted two times with water, each 120 min, and the ratio of solvent to material was 8 ： 1. CONCLUSIONS The optimized extracting technology is stable and feasible.
