Description
Verfahren zur Gewinnung von antibiotischen Wirkstoffen Gegenstand eines älteren Rechts ist ein Verfahren zur Gewinnung von antibiotischen Wirkstoffen, bei dem mit tuberkuloaktiven Stämmen der Gruppe Escherichia coli bebrütete Nährlösungen als Ausgangsmaterial für die Isolierung der Wirkstoffe benutzt wurden.Process for the production of antibiotic active substances subject an earlier right is a process for the production of antibiotic active substances, in the case of the nutrient solutions incubated with tuberculoactive strains of the Escherichia coli group were used as starting material for the isolation of the active substances.
Es wurde nun gefunden, daß sich durch Extraktion der Nährlösungen mit lipoidlösenden Flüssigkeiten eine erhebliche Konzentration der Wirkstoffe erzielen läßt. Als Extraktionsmittel ist insbesondere Äther geeignet, aber auch mit Petroläther, Methylenchlorid, Äthylacetat, Methyläthylketon, Butanol u. dgl. läßt sich das wirksame Prinzip extrahieren.It has now been found that by extracting the nutrient solutions Achieve a significant concentration of the active ingredients with lipoid-dissolving liquids leaves. Ether is particularly suitable as an extractant, but also petroleum ether, Methylene chloride, ethyl acetate, methyl ethyl ketone, butanol and the like can be the effective Extract principle.
Die Extraktion wird zweckmäßig bei Temperaturen unterhalb etwa 45° vorgenommen; falls kontinuierlich unter Verdampfung des Lösungsmittels aus der Extraktlösung gearbeitet wird, wird daher der Druck so weit erniedrigt, daß die Siedetemperatur der Extraktlösung 45° nicht übersteigt. Die bebrütete Nährlösung kann so, wie sie anfällt, also schwach sauer oder schwach alkalisch, extrahiert werden; zweckmäßig wird die Extraktion bei einem pH unterhalb 7 vorgenommen.The extraction is expedient at temperatures below about 45 ° performed; if continuously with evaporation of the solvent from the extract solution is carried out, the pressure is therefore lowered so far that the boiling point the extract solution does not exceed 45 °. The incubated nutrient solution can be like them is obtained, i.e. weakly acidic or weakly alkaline, can be extracted; expedient the extraction is carried out at a pH below 7.
Wird z. B. eine 3 Wochen bebrütete Kultur tuberkuloaktiver Colistämme in Traubenzucker-Hottinger-Bouillon vom PH 4,8 erschöpfend mit Äther extrahiert, so erhält man etwa 0,5 g Extrakt pro Liter Nährlösung. Bei der Extraktion von 6 Tage bebrüteten Hottinger-Bouillonkulturen, die von den Coli befreit und auf pH 6 eingestellt waren, mit Äther fallen etwa 70 mg Extrakt pro Liter Kulturmedium an. Die Extrakte sind gelbe Öle, aus denen sich nach einiger Zeit Kristalle ausscheiden.Is z. For example, if a culture of tuberculoactive coli strains incubated for 3 weeks is extracted exhaustively with ether in glucose Hottinger broth of pH 4.8, about 0.5 g of extract per liter of nutrient solution is obtained. In the extraction of Hottinger broth cultures which have been incubated for 6 days, which have been freed from the Coli and adjusted to pH 6, with ether, about 70 mg of extract per liter of culture medium are obtained. The extracts are yellow oils, from which crystals separate out after a while.
Die gewonnenen, vom Extraktionsmittel befreiten Extrakte sind beim Lochtest und Diffusionstest gegen humane und Kaltblüterbazillen sowie beim Kontaktversuch auf Sautonnährboden kräftig tuberkulocid und sind auch wirksam gegen die Erreger des Paratyphus, Typhus, gegen Streptokokken u. dgl.The extracts obtained and freed from the extractant are at Hole test and diffusion test against human and cold-blooded bacilli as well as in contact tests vigorously tuberculocid on sauton culture medium and are also effective against the Pathogen of paratyphus, typhus, against streptococci and the like.
