[Study on purification process of depsides in Salvia miltiorrhiza with macroporous resin].
OBJECTIVE
To study the technological parameters of the purification process of Depsides in Salvia miltiorrhiza with macroporous resin.


METHODS
The adsorptive characteristics and eluting parameters of the process were studied by taking the content of depsides as index.


RESULTS
85 mL of extractive of depsides (1.25 g x mL(-1)) was purified with a column of macroreticular resin ( Phi30 mm,127 mL) and washed with 4 BV of distilled water, the eluted with 4 BV of 80% ethanol (1% ammonia).


CONCLUSIONS
This process of applying macroporous resin to adsorb and purify depsides in S. miltiorrhiza is feasible.
