Objective: To investigate the rationality and superiority of precise powder decoction pieces system
Salviae Miltiorrhizae Radix et Rhizoma was employed in this study. Method: The second internal transcribed spacer (ITS2) sequence was used as a DNA barcode to identify Salviae Miltiorrhizae Radix et Rhizoma.The chemical composition of the medicinal materials was characterized by HPLC fingerprints
similarity between precise powder decoction pieces and traditional commercial slices were both evaluated.The concents of salvianolic acid B and rosmarinic acid were determined by HPLC
and the characteristic common peaks were identified.In addition
the extraction efficiency was also compared by standard decoction method. Result: Salviae Miltiorrhizae Radix et Rhizoma could be accurately identified by ITS2 sequence.HPLC fingerprints were very similarity between precise powder decoction pieces and traditional commercial slices.However
the extraction efficiency of precise powder decoction pieces was significantly improved with >30% increased dry extract yield and approximately 20%-120% increased dissolution of chemical components.Moreover
the relative standard deviation was also decreased between batches. Conclusion: Precise powder decoction pieces can improve the extraction efficiency and uniformity of traditional commercial slices.
