Description

Verfahren zum dialytischen Extrahieren von Pflanzenstoffen Die Herstellung von Arzneimitteln durch dialytisches Extrahieren von Pflanzenstoffen pflegt man in folgender Weise durchzuführen: Man gibt den Ausgangsstoff in ein Gefäß (z. B. einen Perkolator) und bringt ihn mit einer Flüssigkeit in Berührung, welche die zu extrahierenden Stoffe zu lösen vermag. Das Lösungsmittel durchdringt dann die einschließenden Membranen und läßt die zu extrahierenden Stoffe in gelöster Form durch die Membranen hindurch nach außen diffundieren. Mittels Eindampfens o. dgl. können die extrahierten Stoffe dann schließlich aus dem Lösungsmittel gewonnen werden.Process for the dialytic extraction of plant substances The production of medicinal products by dialytic extraction of plant substances is used to be carried out in the following way: The starting material is placed in a container (e.g. a percolator) and brings it into contact with a liquid which the able to dissolve substances to be extracted. The solvent then penetrates the enclosing membranes and leaves the substances to be extracted in dissolved form diffuse through the membranes to the outside. By means of evaporation or the like. the extracted substances can then finally be recovered from the solvent.

Für gewisse Zwecke ist es bereits vorgeschlagen worden, das Extraktionsgut während der Extraktion gleichzeitig dem Einfluß von Gleich- oder Wechselstrom zu unterwerfen, um die Extraktionsstoffe elektrolytisch aufzuspalten oder um ähnliche Wirkungen zu erzielen. Versuche haben gezeigt, daß man hierbei die Ausbeute um etwa zo bis 25°/o steigern kann,, wenn man das Lösungsmittel dem Durchgang eines elektrischen Wechselstromes von sehr niedriger Frequenz, nämlich von etwa 0,5 bis 5 Hertz, unterwirft. Diese überraschende Tatsache dürfte wahrscheinlich in erster Linie auf Polarisationserscheinungen zurückzuführen sein, die mit periodisch wechselnder Richtung an den Membranen entstehen und die eine Art mikroskopisch-mechanischer Massage der Membran hervorrufen. Es ist verständlich, daß die Membranen auf diesem Wege dauernd sauber und durchlässig gehalten werden können. Die genannte Ausbeutesteigerung ist in der Tat nur bei Verwendung des angegebenen, ungewöhnlich tief liegenden Frequenzbereiches zu erzielen. Die Benutzung von noch geringeren Frequenzen bzw. von Gleichstrom führt hingegen zu einer Verringerung der Ausbeute durch Verstopfung bzw. sogar durch Zerstörung der Membranen, während die Ausbeuteziffer bei Benutzung höherer Frequenzen wieder auf ihr normales Maß sinkt; es machen sich " dann gegebenenfalls nur noch elektrolytische Zersetzungserscheinungen geltend.For certain purposes it has already been proposed to subject the extraction material to the influence of direct or alternating current at the same time during the extraction in order to split the extraction substances electrolytically or to achieve similar effects. Experiments have shown that the yield can be increased by about 10 to 25% if the solvent is subjected to the passage of an electrical alternating current of a very low frequency, namely of about 0.5 to 5 Hertz. This surprising fact is probably primarily due to polarization phenomena, which arise on the membranes with periodically changing directions and which cause a kind of microscopic-mechanical massage of the membrane. It is understandable that the membranes can be kept permanently clean and permeable in this way. The mentioned increase in yield can in fact only be achieved when using the specified, unusually low-lying frequency range. The use of even lower frequencies or direct current, on the other hand, leads to a reduction in the yield due to clogging or even destruction of the membranes, while the yield figure falls back to its normal level when higher frequencies are used; "Then, if necessary, only electrolytic decomposition phenomena make themselves felt.

So ergab sich z. B. bei der Herstellung von Chinatinktur durch Extraktion von zo g Chinarinde mittels einer 2o0/0igen Alkohollösung bei normaler Perkolation eine Trockensubstanz von o,8o9z g und eine Alkaloidmenge von o,o958 g, während bei Anwendung des erfindungsgemäßen, extrem niederperiodischen Wechselstromes die Ausbeute auf 0,9359 g mit o,xzz3 g Alkaloid stieg. Auf dem erfindungsgemäßen Wege wurden also r50% mehr Trockensubstanz und 2o0/0 mehr Alkaloid gewonnen.So z. B. in the production of china tincture by extracting zo g of cinchona bark using a 2o0 / 0 strength alcohol solution with normal percolation a dry substance of 0.8o9z g and an amount of alkaloid of 0.0958 g, while when using the extremely low-period alternating current according to the invention, the yield increases 0.9359 g with o, xzz3 g of alkaloid rose. In the way according to the invention, 50% more dry matter and 20% more alkaloid were obtained.
