Description

Verfahren zur Herstellung neuartiger Lipoidpräparate Die aus dem Zentralnervensystem gewonnenen Phosphatide bzw. phosphatidhaltigen Lipoide weisen den Nachteil großer Empfindlichkeit gegen Feuchtigkeit, Luft und Licht auf und sind auch wegen ihrer strengen, wachsartigen Konsistenz sehr schlecht dosier-und verarbeitbar.Process for the production of novel lipoid preparations from the central nervous system obtained phosphatides or phosphatide-containing lipoids have the disadvantage of large Sensitivity to moisture, air and light and are also due to them strict, waxy consistency, very difficult to dose and process.

Es wurde nun gefunden, daß alle diese Mängel behoben werden können, wenn. man die genannten Stoffe auf trockene Getreidekeime aufbringt.It has now been found that all of these deficiencies can be remedied, if. the substances mentioned are applied to dry grain germs.

Man stellt die Produkte zweckmäßig in der Weise her, daß man die Phosphatide bzw. Lipoide in einem Lösungsmittel (Alkohol, Wasser u. dgl.) löst oder aufschwemmt bzw. erweicht, die Keime innig damit verrührt und schließlich das Lösungsmittel bei niedriger Temperatur in geeigneter Weise, z. B. durch Verdampfen im Vakuum, entfernt. Bildete öl das Lösungsmittel, so entfernt man dieses zunächst z. B. mit Aceton und trocknet alsdann. Man gelangt durch das Verfahren noch bei einem Gehalt von etwa 6o °1o Lipoide zu pulverförmigen bis kleinkörnigen Produkten. Es eignet sich in gleicher Weise für Phosphatide anderer Herkunft.The products are expediently prepared in such a way that the phosphatides or lipoids are dissolved or suspended or softened in a solvent (alcohol, water, etc.), the germs are intimately mixed with them and finally the solvent is suitably used at a low temperature Way, e.g. B. by evaporation in vacuo, removed. If oil formed the solvent, this is first removed z. B. with acetone and then dries. The process leads to powdery to fine-grained products at a content of about 60 ° 10 lipids. It is equally suitable for phosphatides of other origins.

Der zur Verwendung gelangende Träger wird, wenn nötig, vorher gemahlen; besonders gefördert wird der Zweck des Verfahrens, wenn die Getreidekeime vor ihrer Verwendung mit Wasser oder einem organischen Lösungsmittel - extrahiert werden.The carrier used is, if necessary, ground beforehand; The purpose of the procedure is particularly encouraged when the grain germs are in front of them Use with water or an organic solvent - be extracted.

Das vorliegende Verfahren gestattet erstmals Phosphatide und phosphatidhaltige Lipoide in hoher Konzentration (y5 bzw. 5o °f,) als feinkörnige bzw. pulverförmige Produkte-zu erhalten, welche sich trotz ihrer feinen Verteilung.und trotz der leichten Veränderlichkeit der Phosphatide, insbesondere der Lipoide des Zentralnervensystems, als haltbar erwiesen haben. Beispiel 5oo g Gesamtlipoide aus Hirn werden mit 4oo g. Alkohol in der Wärme verflüssigt und alsdann mit 5oo g Gerstenkeimen, welche vorher entstaubt, gemahlen und mit Alkohol extrahiert wurden, längere Zeit intensiv durchgeknetet. Schließlich destilliert man den Alkohol im Vakuum ab. Man gewinnt auf diese Weise z kg eines 5o °J, Lipoide enthaltenden Produkts.The present process allows for the first time phosphatides and those containing phosphatides Lipoids in high concentration (y5 or 50 ° f,) as fine-grained or powdery Products-to obtain which, despite their fine distribution. And despite the light Variability of the phosphatides, especially the lipoids of the central nervous system, have proven to be durable. Example 500 g of total lipids from brain are combined with 400 G. Alcohol liquefied in the heat and then with 500 g of barley germs, which dusted, ground and extracted with alcohol beforehand, intensively for a long time kneaded. Finally, the alcohol is distilled off in vacuo. One wins in this way z kg of a product containing 50 ° J, lipoids.

PATENTANSPRUCIR: Verfahren zur Herstellung neuartiger Lipoidpräparate, dadurch gekennzeichnet, daß man Phosphatide oder Phosphatide enthaltende Lipoide in innige Mischung mit trockenen Getreidekeimen, welche zweckmäßig vor ihrer Verwendung mit einem Lösungsmittel, in dem sie praktisch unlöslich sind, extrahiert wurden, bringt, indem man z. B. diese Stoffe mit den Phosphatiden bzw. Lipoiden in einem solchen Lösungsmittel behandelt, in welchem erstere praktisch unlöslich, letztere dagegen verteilbar bzw. löslich sind, worauf man das Lösungsmittel auf geeignete Weise entfernt.PATENT APPLICATION: Process for the production of novel lipoid preparations, characterized in that lipoids containing phosphatides or phosphatides are used in intimate mixture with dry grain germs, which expedient before using them with a solvent in which they are practically insoluble, were extracted, brings by z. B. these substances with the phosphatides or Lipoids treated in such a solvent in which the former is practical insoluble, the latter on the other hand distributable or soluble, whereupon the solvent removed in an appropriate manner.
