Description
Verfahren zur Gewinnung haltbarer Filicinlösungen Es ist bisher keine Möglichkeit bekannt, die bei der Behandlung von Filixextrakten mit Baryt und darauf folgendem Ansäuern entstehenden, als Filicin bezeichneten Produkte in Form haltbarer Lösungen dem Arzneischatz zuzuführen, vielmehr verändern sich bereits die alkoholischen Extrakte, und auch in Äther gelöstes Filicin zersetzt sich, wie festgestellt wurde, .beim Stehen, wobei störende Abscheidungen großer Mengen therapeutisch unwirksamer Stoffe auftreten.Process for obtaining durable filicin solutions So far there is none Possibility known in the treatment of filix extracts with barite and on it products called filicin resulting from acidification in the form of more durable products Adding solutions to the medicinal treasure, rather the alcoholic ones are already changing Extracts, and also filicin dissolved in ether, decomposes, as has been determined when standing, with disturbing deposits of large amounts therapeutically ineffective Substances occur.
Es hat sich nun gezeigt, daß man durch Lösen des Filicins in Tetrachlorkohlenstoff Präparate von ausgezeichneter Haltbarkeit gewinnt. Infolge des außerordentlich großen Lösungsvermögens desselben für Filicinsäure werden bei der Herstellung der Lösung nur sehr geringe Mengen benötigt, andererseits wird durch die Gegenwart des Tetrachlorkohlenstoffs die Wirkung des in nur geringen Mengen zur Anwendung gelangenden Filicins noch gesteigert.It has now been shown that by dissolving the filicin in carbon tetrachloride Preparations of excellent shelf life wins. As a result of the extraordinarily large Solvent power of the same for filicic acid will be used in the preparation of the solution only very small amounts are required, on the other hand, due to the presence of carbon tetrachloride the effect of the filicin, which is used in only small amounts, is further increased.
B e i s p i e 1 : Ein in bekannter Weise aus Rhizoma filicis dargestellter Extrakt wird mit einer schwach alkalischen Lösung, z. B. von Barytwasser, extrahiert, worauf man aus der Lösung in bekannter Weise mit verdünnter Säure das Filicin ausfällt. Das getrocknete, gegebenenfalls vorher z. B. durch Umfällen noch weiter gereinigte Filicin wird in 3 Teilen Tetrachlorkohlenstoff gelöst.B e i s p i e 1: A shown in a known manner from Rhizoma filicis Extract is mixed with a weakly alkaline solution, e.g. B. from barite water, extracted, whereupon the filicin is precipitated from the solution in a known manner with dilute acid. The dried, optionally previously z. B. still further purified by falling over Filicin is dissolved in 3 parts of carbon tetrachloride.
