Study on the Integration Technique for Extracting Liposoluble and Water-soluble Components of Salvia Miltiorrniza

Objective To optimize an integration technique for extracting the liposoluble and water-soluble components of Salvia miltiorrhiza. Methods Salvianolic acid B and Tanshinone ⅡA were selected as marker components and determined by HPLC to optimize the integration extract process of Salvia miltiorrhiza by orthogonal test. Results The liposoluble and water-soluble active components of Salvia miltiorrhiza were efficiently extracted by the optimum integration technique. The integration technique for extracting was obtained:Salvia miltiorrhiza was added with 8 times alcohol of 70% and extracted 1 hour for 2 times. Conclusion The liposoluble and water-soluble active components of Salvia miltiorrhiza can be extracted simultaneously by the novel extraction process which was reasonable and feasible. This new technique can be employed to reduce time, working and energy, and be suitable for the morden production.
