Effect of different solvents on percentage
extraction of tanshinones

The experimental results show that except n-butyl
acetate, ethanol, methanol, acetone, n-butanol, ethyl
acetate and tetrahydrofuran can reach almost the
same high percentage extraction of tanshinones. As
the ethanol is non-toxic and can be mixed with water
in different ratio, so it is chosen to extract tan-
shinones from Salvia miltiorrhiza bunge.
