Patent number: 8815299Abstract: A method for obtaining an extract containing the natural mixture of conjugated equine estrogens by liquid-liquid extraction of the mixture of conjugated equine estrogens, wherein the mixture obtained is depleted in non-conjugated lipophilic compounds selected from the group consisting of non-conjugated flavonoids, non-conjugated isoflavonoids, non-conjugated norisoprenoids, non-conjugated steroids, in particular androstane and pregnane steroids, and comparable non-conjugated compounds.Type: GrantFiled: June 13, 2008Date of Patent: August 26, 2014Assignee: Abbott Products GmbHInventors: Ivan Ban, Klaus-Guenter Gerling, Hans-Joerg Mueller, Stefan Wachsmann

Patent number: 7524833Abstract: A method and apparatus for concentrating and stabilizing conjugated estrogens from pregnant mare urine on solid adsorbent supports to obtain a starting material for pharmaceuticals that contain a natural mixture of conjugated estrogen mixtures on cartridges in the vicinity of the horses. The adsorbent cartridges can be loaded at the site of urine collection so it is unnecessary to transport large volumes of urine to a central processing point. The loading process can take continuously over a period of weeks until the column is saturated. The effluent urine remains at the site where facilities for its disposal are available. Only the loaded cartridge is transported, and transport can occur at longer intervals of up to several weeks. The stability of the conjugated estrogens on the adsorber assures there is no risk of decomposition.Type: GrantFiled: June 13, 2006Date of Patent: April 28, 2009Assignee: Solvay Pharmaceuticals GmbHInventors: Juergen Ahnsorge, Ivan Ban, Heinz-Helmer Rasche

Patent number: 7081451Abstract: A method and apparatus for concentrating and stabilizing conjugated estrogens from pregnant mare urine on solid adsorbent supports to obtain a starting material for pharmaceuticals that contain a natural mixture of conjugated estrogens as active ingredient. The apparatus is suitable for decentralized concentration and stabilization of conjugated estrogen mixtures on cartridges in the vicinity of the horses. The adsorber cartridges can be loaded at the site of urine collection so it is unnecessary to transport large volumes of urine to a central processing point. The loading process can take continuously over a period of weeks until the column is saturated. The effluent urine remains at the site where facilities for its disposal are available.
