Abstract

Wynalazek ujawnia kokrysztal mirycetyna - piracetam o wzorze 3 znajdujacy zastosowanie w przemysle farmaceutycznym i/lub kosmetycznym. Wynalazek dotyczy równiez sposobu otrzymywania kokrysztalu mirycetyna - piracetam o wzorze 3 charakteryzujacego sie na tym, ze mirycytyne o wzorze 1 w ilosci od 25 do 50 mg oraz piracetam o wzorze 2 w ilosci od 200 do 300 mg rozpuszcza sie w od 5 do 10 ml, etanolu, po czym calosc miesza sie, przesacza sie, a nastepnie pozostawia sie do powolnego odparowania w temperaturze pokojowej, a po 14 do 21 dniach zbiera sie krysztaly. W innej metodzie sposobu otrzymywania kokrysztalu mirycetyna - piracetam o wzorze 3 w stalowym naczyniu mlyna kulowego umieszcza sie mirycytyne o wzorze 1 i piracetam o wzorze 2 w ilosci stechiometrycznej 1: 1, po czym dodaje sie polarny, aprotyczny rozpuszczalnik 50 ?l na kazde 50 mg mirycetyny, a nastepnie mieszanine poddaje sie mieleniu przez czas od 5 do 45 minut, przy czestosci drgan 50-60 Hz, i tak otrzymany material mikrokrystaliczny suszy sie w temperaturze pokojowej przez okres 12-24 godzin i poddaje sie analizie na dyfraktometrze proszkowym.The invention discloses the myricetin - piracetam formula 3 which is used in the pharmaceutical and / or cosmetics industry. The invention also relates to a method for the preparation of myricetin - piracetam 3, which is characterized in that myricitin 1 in 25 to 50 mg and piracetam 2 in 200 to 300 mg are dissolved in 5 to 10 ml, ethanol, after which the whole is mixed, filtered, and then allowed to slowly evaporate at room temperature, and after 14 to 21 days crystals collect. In another method of obtaining the myricetin - piracetam formula 3 co-crystal, a ball mill is placed in a steel mill with myristicine formula 1 and piracetam formula 2 in a stoichiometric amount of 1: 1, followed by the addition of a polar aprotic solvent of 50 ml for each 50 mg myricetin, and then the mixture is milled for 5 to 45 minutes, with a 50-60 Hz vibration frequency, and the microcrystalline material thus obtained is dried at room temperature for a period of 12-24 hours and analyzed on a powder diffractometer.
