Abstract:

To compare the differences of effective components of Salvia miltiorrhiza from different strains, the contents of 4 fat-soluble components including tanshinone IIA and the contents of 3 water-soluble components including salvianolic acid B were measured by HPLC, and the data were analyzed by SPSS software. By comparison of the two major kinds of ingredients, it was found that the contents of fatsoluble components in 3, 7 strains were relatively higher, and the contents of watersoluble components in 1, 9, 10 strains were higher, so we could consider to cultivate 3,7 strains for the raw materials of the extraction of fatsoluble component, while cultivating 1,9,10 strains for the extraction of watersoluble components. The significance analysis results showed that there were significant differences in the main watersoluble and fatsoluble components of 10 different strains of S. miltiorrhiza. This study can provide a basis for the selection of good germplasm of S. miltiorrhiza.
