Objective: To discuss preparation process parameters of Salviae Miltiorrhizae Radix et Rhizoma extract in mass production. Method: Single factor tests were adopted

pretreatment of raw materials of tanshinone extract was investigated by taking contents of cryptotanshinone and tanshinone ⅡA as indicators.Water extraction temperature of Salviae Miltiorrhizae Radix et Rhizoma was optimized by taking solid-containing content and the content of salvianolic acid B as indexes.With solid-containing content

the content of salvianolic acid B and fingerprints as indicators

raw materials of water extraction for Salviae Miltiorrhizae Radix et Rhizoma were determined.Fingerprints was employed to determine optimum concentration temperature of water extract of Salviae Miltiorrhizae Radix et Rhizoma. Result: Pretreatment of raw materials of tanshinone extract was cutting into small pieces of 1-2 cm.Raw materials of total phenolic acid extract in Salviae Miltiorrhizae Radix et Rhizoma can use the residues of tanshinone extract

extraction temperature was revised to 100℃

the concentrated temperature was revised to 80℃. Conclusion: These optimized process conditions are stable and feasible

which can provide experimental basis for large-scale production of Salviae Miltiorrhizae Radix et Rhizoma extract.
