A 61 k Jeleniogórskie Zaklady Farmaceutyczne "Polfa" *) Jelenia Góra, Poland The method of obtaining the liver extract The patent is valid from November 29, 1961. Additional patent to the patent No. 40247 The patent No. 40247 describes a method of obtaining a liver extract based on the fact that The active substances of the liver, obtained in a known manner by salting, are first extracted four times with alcohol extracts from the intermediate extractions graying and then the fifth extraction with fresh 70% ethyl alcohol. The obtained extract is concentrated and contained in it, the active substances are adsorbed on active carbon, from which they are eluted with ethyl alcohol in a counter-current. By carrying out the process in counter-current, the result is that smaller than usual amounts of solvents are used, which accordingly shortens the distillation time and self- *) The owner of the patent stated that the authors of the invention are Felicjan Mozolowski, MSc. Zygmunt Zborucki and Jan Musial. The aim of the invention is to further reduce the temperature-induced loss of vitamin Bi2. This objective is achieved according to the invention by using about 70% of the salted active body of the liver in the extraction process. of methanol solution and countercurrent operation at the boiling point of this solvent, ie at 64.7 ° C., instead of about 78 ° C. (ethanol boiling point). For the first extraction of the wet sediment of active bodies, an 80% methanol solution is used according to the hydrometer indicated at a temperature of 15 ° C. Further operations such as concentration of the extract, adsorption on carbon, elution, etc. are carried out as described in the main patent. ^ PL
