[Study on extraction process of aqueous part of radix Salvia miltiorrhiza].
OBJECTIVE
To find out the optimum extraction process for total salvianolic acid part of radix Salviae miltiorrhizae.


METHODS
The extraction process was studied by orthogonal design with the danshen su content determined by RP-HPLC as index.


RESULTS
A3B3C2D1 is the best extraction condition of aqueous part from radix Salvia miltiorrhiza.


CONCLUSIONS
This extraction process shows total salvianolic acid has high content and good stability.
