The effective-part of Danshen was studied in this article. The extractingtechnical of liposoluble(total tanshinones) and hydrosoluble(total salvianolicacid)part of Danshen were carried out with orthogonal test, and the technicalwere conformed, then the two effective-parts were produced. The content oftotal tanshinones and total salvianolic acid could reach above 50%.
Orthogonal design was used for studying the effect of 4 factors(alcoholdensity, alcohol volume, time and times) to extractin...
