Abstract:
A method for isolating cimiracemate A from a Cimicifuga species is disclosed, comprising the steps of a) providing a sufficient quantity of raw materials from the Cimicifuga species, b) mixing the raw materials from the Cimicifuga species with an aqueous polar solvent at a temperature of about 20° C. to about 28° C. to obtain a solvent extract comprising cimiracemate A, and c) isolating cimiracemate A from the solvent extract.
