The invention relates to a method for extracting an extract, which contains the natural mixture of conjugated equine estrogens, by the liquid-liquid extraction of the mixture of conjugated equine estrogens. The extracted mixture is depleted of non-conjugated lipophilic compounds from the group consisting of non-conjugated flavonoids, non-conjugated isoflavonoids, non-conjugated norisoprenoids, non-conjugated steroids, particularly androstane and pregnane steroids, and comparable non-conjugated compounds. |
