Description
Verfahren zur Gewinnung von Ergosterin aus Hefe In dem Patent 517 499 ist ein Verfahren zur Gewinnung von Sterinen aus Mikroorganismen oder Tier- oder Pflanzenteilen durch Extraktion beschrieben, bei dem man die genannten Ausgangsmaterialien einem enzymatischen Abbau unterwirft, durch den die Zellwandungen aufgelöst werden. Es wird auf diese Weise die Freilegung der zu gewinnenden Verbindungen aus ihren organischen Komplexen bedeutend erleichtert. Bei der Herstellung von Ergosterin, z. B. aus Hefe, wird durch die Autolyse der Zellkörper aufgelöst- und damit die nachfolgende chemische Behandlung mit alkoholischer Kalilauge sehr wirksam unterstützt.Process for obtaining ergosterol from yeast Patent 517 499 describes a process for obtaining sterols from microorganisms or parts of animals or plants by extraction, in which the starting materials mentioned are subjected to enzymatic degradation through which the cell walls are broken down. In this way, the exposure of the compounds to be obtained from their organic complexes is significantly facilitated. In the production of ergosterol, e.g. B. from yeast, is dissolved by the autolysis of the cell body and thus the subsequent chemical treatment with alcoholic potassium hydroxide is very effective.
Es wurde nun gefunden, daß nach diesem Verfahren in besonders vorteilhafter Weise Ergosterin aus Hefe gewonnen wird, wenn man die Hauptmenge des Ausgangsmaterials durch enzymatischen Abbau, zweckmäßig unter sterilen Bedingungen, in, wasserlösliche Verbindungen überführt, ohne Erhitzen der verflüssigten Masse von Odem ungelösten Rest abtrennt, und dann jedes der getrennten Produkte für sich auf die gewünschten Verbin-.dun,gen verarbeitet. Diese Arbeitsweise bietet den großen Vorteil, daß in dem unlöslichen Anteil das Ergosterin sich stark anreichert. Die Isolierung dies-er Verbindung läßt sich nunmehr mit einem bedeutend geringeren Aufwand an Reagenzien unter gleichzeitig vereinfachten Arbeitsbedingungen durchführen.It has now been found that this process is particularly advantageous Way ergosterol is obtained from yeast if you take the main amount of the starting material by enzymatic degradation, expediently under sterile conditions, in water-soluble Compounds transferred without heating the liquefied mass of undissolved edema The remainder is separated, and then each of the separated products is individually tailored to the desired Connect-.dun, gene processed. This mode of operation has the great advantage that in the insoluble part of the ergosterol accumulates strongly. The isolation of this-he Connection can now be made with a significantly lower expenditure of reagents carry out under simultaneously simplified working conditions.
Ein weiterer Vorteildes Verfahrens besteht darin, daß bei der obigen Arbeitsweise, unter Einhaltung einer Wasserstoffionenkonzentration pH = 6-7, von den Abbauprodukten der Hefe z. B. bestimmte Aminosäuren, wie Tyrosin, oder Purinderivate, wie Xanthin u. a., direkt in großer Reinheit in demselben Arbeitsgang als wertvolle Nebenprodukte anfallen.Another advantage of the process is that in the above procedure, while maintaining a hydrogen ion concentration of pH = 6-7, of the yeast degradation products, for. B. certain amino acids, such as tyrosine, or purine derivatives, such as xanthine and others. , Arise directly in high purity in the same operation as valuable by-products.
Beispiel 4ooo Gewichtsteile Preßhefe werden nach der Verflüssigung mit 8o Volumteilen Essigester durch Zufügen, von verdünntem Amnioniak auf eine Wasserstoffion#enkonzentratiOn PH - 6-7 gebracht. Nachdem das Autolysat mit weiteren 2o Volumteilen Essigester durchgeschüttelt wurde, bleibt es unter Gärverschluß sich selbst überlassen. Nach einigen Tagen ist der enzymatische Abbau der Zellsubstanz so weit fortgeschritten, daß Tyrosin sich abzuscheiden beginnt. Die grobkörnigen Kristallaggregate, etwa:2o Gewichtsteile, werden nun mit Hilfe eines engmaschigen Drahtsiebes abgetrennt. Die vom Tyrosin abgetrennte Autolysenflüssigkeit wird darauf zentrifugiert, um die nicht gelösten Anteile zu Z> gewinnen. Letztere bilden eine halbfeste Masse von etwa i ooo Volumteilen und enthalten das gesamte Ergosterin. Mit 4oo Gewichtsteilen Alkali und geringen Mengen Lösungsmitteln läßt sich nach kurzer Verseifung alles Ergosterin in freie Form bringen. Es wird in einer Ausbeute von etwa 14 Gewichtstellen als reines Präparat vom Schmelzpunkt 155 bis 1570 gewonnen.Example 4ooo parts by weight of pressed yeast after liquefaction with 8o Essigester parts by volume by the addition of dilute hydrogen Amnioniak a final concentration PH # - brought 6-7. After the autolysate has been shaken through with further 20 parts by volume of ethyl acetate, it is left to ferment under the fermentation seal. After a few days, the enzymatic breakdown of the cell substance has progressed so far that tyrosine begins to be deposited. The coarse-grained crystal aggregates, about: 2o parts by weight, are now separated off with the help of a close-meshed wire sieve. The separated from tyrosine Autolysenflüssigkeit is centrifuged out, win the parts not dissolved to Z>. The latter form a semi-solid mass of about 1,000 parts by volume and contain all of the ergosterol. With 400 parts by weight of alkali and small amounts of solvents, all ergosterol can be brought into free form after a short saponification. It is obtained in a yield of about 14 weight points as a pure preparation with a melting point of 155 to 1570 .
Die Verringerung des Aufwandes an Reagenzien beträgt, verglichen mit den sonst üblichen Darstellungsverfahren, 50 lo, #die Ausbentesteigerung an Ergosterin über i oo "/". Aus dem abgetrennten flüssigen Anteil können weitere wertvolle Stoffe, z. B. Leucin, leicht in größeren Mengen und nach bekannten Arbeitsweisen auch alle übrigen Hefespaltprodukte in guter Ausbeute gewonnen werden.The reduction in the expenditure of reagents compared with the otherwise customary preparation methods is 50 %, the increase in the yield of ergosterol over 10% "/". Other valuable substances such. B. leucine, easily in larger quantities and all other yeast cleavage products can be obtained in good yield according to known procedures.
Man kann auch so verfahren, daß man das angereicherte Rohprodukt zur Gewinnung der ErgQsterinkomponenten nach einer einfachen Entwässerung durch Veresterung, z. B. mittels Essigsäureanhydrids, in das Ergosterinacetat überführt, das durch seine ausgezeichnete Kristallisierharkeit leicht zu isolieren ist.One can also proceed in such a way that the enriched crude product is used Obtaining the ErgQsterol components after a simple dehydration by esterification, z. B. by means of acetic anhydride, converted into the ergosterol acetate, which is carried out by its excellent crystallizability is easy to isolate.
