Salvianolic Acids D and E: Two New Depsides from Salvia miltiorrhiza.
Four water-soluble constituents, salvianolic acids D, E, ethyl lithospermate, and isoferulic acid were isolated from SALVIA MILTIORRHIZA. Salvianolic acids D and E are new depsides. Their chemical structures were determined by chemical and spectral analysis. The structure of salvianolic acid D was finally confirmed by comparison with a synthetic product.
