Description

  

  Verfahren zur Reinigung von     Extrakten        segualhormonartig    wirkender     Stoffe.       Die aus den verschiedenen Ausgangs  materialien (Sexualorganen, Harn,     Faeces,          pflanzlichen    Organismen) gewonnenen Roh  extrakte     sexualhormonartiger    Stoffe ergeben  nach den bisher bekannt gewordenen Reini  gungsmethoden unbefriedigende Ausbeuten an  reinem Hormon.  



  Es wurde gefunden, dass durch mehrmali  ges Ausziehen einer wässerig     methylalkoho-          lischen    Lösung der Extrakte mit     Petroläther     in der Weise, dass die     methylalkoholische    Lö  sung immer weiter mit Wasser verdünnt wird,  so dass das Sexualhormon begleitende Stoffe in  Form von chemischen Molekular- und Addi  tionsverbindungen des     Petroläthers    in die       Petrolätherschicht    übergehen, ein Produkt er  halten wird, welches beim kastrierten Tier  die Geschlechtsorgane zur Entwicklung und  zum Wachstum bringt.  



  Man verfährt zum Beispiel wie folgt  Man löst rohes Hormonöl in Methylalko  hol und gibt so viel Wasser hinzu, dass die  Lösung etwa     70'/o    Methylalkohol enthält.    Diese Lösung wird erschöpfend mit     Petrol-          äther    extrahiert, alsdann die     methylalkoho-          lische    Lösung durch weiteren Zusatz von       Wasser        bis        auf        etwa        60        %        Methylalkohol-          gehalt    gebracht,

   worauf erneut mit     Petrol-          äther    extrahiert wird. Beim dritten Male  bringt man vor der Extraktion mit     Petroläther     die Verdünnung der     methylalkoholischen    Lö  sung auf etwa     50'/o    Methylalkohol.  



  Bei der Behandlung mit dem     Petroläther     bilden sich zwischen den Begleitstoffen des  Hormons und dem     Petroläther        Additions-    und       Molekularverbindungen,    die in den     Petrol-          äther    übergehen. Das Hormon dagegen ver  bleibt in der wässerig -     methylalkoholischen     Lösung, nach deren Eindunsten man das  Hormon in einer Ausbeute von     95-1000/0     mit höherer Reinheit wieder erhält.



  Process for the purification of extracts with segual hormone-like substances. The raw extracts of sex hormone-like substances obtained from the various starting materials (sexual organs, urine, faeces, plant organisms) result in unsatisfactory yields of pure hormone according to the previously known cleaning methods.



  It has been found that by repeatedly drawing out an aqueous methyl alcoholic solution of the extracts with petroleum ether in such a way that the methyl alcoholic solution is diluted more and more with water, so that the substances accompanying the sex hormone in the form of chemical molecular and addition compounds the petroleum ether pass into the petroleum ether layer, a product he will keep, which brings the genital organs to development and growth in the castrated animal.



  One proceeds, for example, as follows: Dissolve crude hormone oil in methyl alcohol and add so much water that the solution contains about 70% methyl alcohol. This solution is exhaustively extracted with petroleum ether, then the methyl alcohol solution is brought to about 60% methyl alcohol by further addition of water,

   whereupon it is extracted again with petroleum ether. The third time, before the extraction with petroleum ether, the methyl alcoholic solution is diluted to about 50% methyl alcohol.



  During the treatment with petroleum ether, addition and molecular compounds are formed between the accompanying substances of the hormone and the petroleum ether, which are transferred to the petroleum ether. The hormone, on the other hand, remains in the aqueous - methyl alcoholic solution, after the evaporation of which the hormone is obtained again in a yield of 95-1000 / 0 with higher purity.
