Abstract: A new process, particularly simple and economical, for FSH and LH separation and purification starting from crude HMG preferably urinary, comprising the following steps:1) optional exhaustion of crude HMG viral charge in aqueous EtOH2) ion-exchange chromatography on weakly basic anionic resins of DEAE type;3) affinity chromatography on resin having an antraquinone derivative as a ligand;4) optional ion-exchange chromatography on strongly basic anionic resins;Hormones obtained thereby, in particularly pure form and having high specific activity, may subsequently undergo a depyrogenation step.

Abstract: The salts, in the crystalline form, of ibuprofen and naproxen with N-(2-hydroxyethyl) pyrrolidine are prepared by dissolving ibuprofen and naproxen respectively in a suitable organic solvent, by adding N-(2-hydroxyethyl) pyrrolidine, by letting the compounds react, by removing the solvent and by crystallizing the obtained salt from a solution in an apolar and aprotic solvent.Said salts have a high solubility in water and are used for preparing pharmaceutic compositions for oral and other administrations.
