A method for obtaining an extract containing the natural mixture of conjugated equine estrogens in which a mixture of conjugated estrogens obtained by solid-phase extraction from pregnant mares' urine is depleted in phenolic urine contents and 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.

Method for obtaining a natural mixture of conjugated equine estrogens

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.

Method and apparatus for concentrating and stabilizing conjugated estrogens from mare urine

A method of separating cresol from mares' urine by pervaporation using pore-free polymeric silicone membranes in which starting urine solutions containing high-quality and -quantity conjugated estrogens with a reduced or substantially removed cresol content are provided which are advantageously suitable for obtaining natural mixtures of conjugated estrogens from pregnant mares' urine.

Separation of cresol from mares' urine

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. 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.

Device for concentrating and stabilizing conjugated estrogens from mare urine

A process for producing porous polymer beads in which polymers, preferably polyolefins or polyvinyl chloride, are dissolved in a solvent, preferably halogenated hydrocarbons or alkyl esters, at temperatures close to the boiling point of the solvent. The hot polymer solution is cooled, and the polymer beads formed during the cooling process are separated, washed and dried. The porous polymer beads are useful, for example, as catalyst carriers or as adsorption agents.

Process for producing porous polymer globules

A method for obtaining an extract from urine of pregnant mares containing a natural mixture of conjugated estrogens by solid-phase extraction of the mixture of conjugated estrogens from the urine of pregnant mares on RP silica gel.

Method for obtaining estrogens from pregnant mare urine by solid-phase

A method for obtaining an extract containing the natural mixture of conjugated estrogens from mare urine by solid-phase extraction of the mixture of conjugated estrogens from the urine of pregnant mares on non-ionic semi-polar polymeric adsorber resins.
