Abstract:
Objective:To study the effect of the extracting time and solvent on the concentration of main active components in Salvia Miltiorrhiza Bunge, and to provide basic data and theoretical guide to GEP(general extraction practice). Methods: Salvianolic acid B and Tanshinone ⅡA were extracted by 90% alcohol and water respectively from Salvia Miltiorrhiza Bunge and their contents were etermined by means of HPLC at regular intervals. Results: Extracting time and solvent were significant factors in the prcess of concentrating Salvianolic acid B and Tanshinone ⅡA from extract of Salvia Miltiorrhiza Bunge. Conclusion: Water is suitable for extracting Salvianolic acids, the extracting time is 40～50 minutes; alcohol is suitable for extracting Tanshinones, the extracting time is 20～30 minutes.
