Description
Verfahren zur Herstellung eines therapeutisch wirksamen Extraktes aus Rhamnusrinde. Die Erfindung betrifft ein Verfahren zur Herstellung eines therapeutisch wirksamen Extraktes aus Rhamnusrinde, und zwar insbesondere der Droge Rhamus carneolica.Process for the production of a therapeutically effective extract from rhamnus bark. The invention relates to a method for producing a therapeutic effective extract from rhamnus bark, in particular the drug Rhamus carneolica.
Rhamnusrinde hat man für medizinische Zwecke schon verwendet, indem man,die Extraktion der Rinde durch eine Vorbehandlung, bestehend in einem längeren Erwärmen auf Wassersiedehitze, d. h. roo°, vornahm, worauf dann die Extraktion folgte. Es hat sich aber herausgestellt, daß dieses Verfahren wesentlich verbessert werden kann, indem man die Erwärmung unter -Druck, beispielsweise im _ Autoklaven, bis. auf etwa 14o° steigert. Man bekommt einen Extrakt von qualitativ und quantitativ besseren Eigenschaften. Klinische Versuche haben gezeigt, daß die auf diese Weise hergestellten Extrakte, insbesondere von Rhamnus carneolica, milder und dabei aber auch-stärker wirken als die Extrakte, die nach dem bisher gebräuchlichen Verfahren hergestellt wurden. Man darf allerdings die Erwärmung nicht über 14o° steigern, weil bei zu hohem Druck eine Zersetzung des Extraktes: beginnt und dadurch die klinischen Wirkungen wieder verringert werden. Außerdem wird die Extraktausbeutung durch die Erwärmung bis auf 14o° gesteigert, und zwar von 15 Prozent bis auf etwa 25 Prozent der Trockensubstanz. Während die bisher verwendeten Rharnnuspräparate im allgemeinen von Rhamnus frangula herstammen, ist es auf diese Weise möglich, auch Rhamnus carneolica für therapeutische Zwecke zu verwenden,- was bisher nicht der Fall gewesen ist.Rhamnus bark has already been used for medicinal purposes by one, the extraction of the bark through a pretreatment consisting in a lengthy one Heating to boiling water, d. H. roo °, followed by extraction. It has been found, however, that this method can be significantly improved can by heating under pressure, for example in the _ autoclave, up to. increases to about 14o °. You get an extract of qualitative and quantitative better properties. Clinical trials have shown this to work produced extracts, especially from Rhamnus carneolica, milder and at the same time also-have a stronger effect than the extracts made after the previously common method were manufactured. However, you must not increase the temperature above 14o °, because if the pressure is too high a decomposition of the extract: begins and thus the clinical Effects are reduced again. In addition, the extraction of the extract is increased by the Warming increased to 14o °, from 15 percent to about 25 percent the dry matter. While the rharnus preparations used so far in general come from Rhamnus frangula, it is possible in this way to also include Rhamnus carneolica to use for therapeutic purposes - which has not been the case so far.
Die nach dem geschilderten Verfahren hergestellten Extrakte haben eine hohe klinische Wirksamkeit und ' einen: wenig ausgeprägten Geschmack; sie zeigen auch nicht die Nachteile der Präparate von Rhamnus frangula, die hauptsächlich in Brechreiz bestehen. Durch den Erhitzungsprozeß bis auf 14o° werden die in Wasser und Alkohol unlöslichen und therapeutisch unwirksamen Verbindungen anscheinend hydrolysiert und in wirksame wasserlösliche Stoffe übergeführt. Beispiel. 50 g getrocknete Rinde von Rhamnus carneolica werden im Autoklaven mit überhitzten Dämpfen auf r4o° etwa 8 Stundenlang erhitzt. Nach dem Herausnehmen werden die Rinden zerkleinert undi in der üblichen Weise extrahiert.The extracts produced by the process described have a high clinical effectiveness and a: little pronounced taste; they also do not show the disadvantages of the preparations of Rhamnus frangula, which consist mainly of nausea. As a result of the heating process up to 140 °, the therapeutically inactive compounds which are insoluble in water and alcohol are apparently hydrolyzed and converted into effective water-soluble substances. Example. 50 g of dried bark of Rhamnus carneolica are heated in an autoclave with superheated vapors to r40 ° for about 8 hours. Once removed, the bark is chopped up and extracted in the usual way.
