Description

Verfahren zur schonenden Gewinnung von Extraktivstoffen aus Körpersäften In dem Patent 662 634 ist ein Verfahren zur schonenden Gewinnung von Extraktivstoffen aus Körpersäften beschrieben, dem der Gedanke zugrunde liegt, auf die zu extrahierenden Körpersäfte gleichzeitig ein fettlösendes und ein kapillaraktives Prinzip zur Einwirkung zu bringen. Dies soll nach der genannten Patentschrift in der Weise geschehen, daß man die Körpersäfte mit fettlösenden, grenzfläche:naktiven Flüssigkeiten oder Flüssigkeitsgemischen von geringer Wasserlöslichkeit, beispielsweise mit Octylalkohol, oder mit fettl#ös,enden, wasserunlöslichen Flüssigkeiten mit geringer oder ohne Grenzflächenaktivität, beispielsweise mit Xylol, zusammen mit wasserlöslichen, stark kapillaraktiven Stoffen, die mit den Bestandteilen der Körpersäfte nicht reagieren, beispiels# weise mit .,oxalkyllerten Fettalkoholderivaten, extrahiert. . Method for the gentle extraction of extractive substances from body juices The patent 662 634 describes a method for the gentle extraction of extractive substances from body juices, which is based on the idea of simultaneously applying a fat-dissolving and a capillary-active principle to the body fluids to be extracted. According to the patent specification mentioned, this should be done in such a way that the body fluids with fat-dissolving, interface: inactive liquids or liquid mixtures of low water solubility, for example with octyl alcohol or with fat-free, end, water-insoluble liquids with little or no interfacial activity, for example with Xylene, together with water-soluble, highly capillary-active substances that do not react with the constituents of the body fluids, for example with., Oxyalkylated fatty alcohol derivatives. .

In weiterer Ausbildung dieses Verfahrens wurde nun gefunden, daß man mit Vorteil auch so vorgehen kann, daß man die Körpersäfte mit fettlösenden, greenzflächenaktiven Flüssigkeiten oder Flüssigkeitsgernischen von geringer Wasserlöslichkeit, zusammen mit wasserlöslichen, grenzflächenaktiven St#offen, die mit den Bestandteilen der Körpersäfte chemisch nicht reagieren, oder mit wasserunlöslichen, fettlösenden Flüssigkeiten von ge- ringer oder ohne Grenzflächenaktivität behandelt. Beispiele i. iol Hirnpreßsaft werden bei pii 5,o mit einem Gemisch von 5 o ccm Decylalkohol und 5o-ccm Xylol behandelt; nach 3stündigem Durchleiten von Luft wird das flüssige Lipoid-Alkohol-Gemisch durch Zentrifugieren abgetrennt. Nach Verdunsten des Alkohols hinterbleibt das Lipoid als hellbraune, wachsartige Masse, die in Benzol, Äther, Xylol, CI-il,or,oform, Methylenchlorid leicht in Lösung geht, in Methyl- und Äthylalkohol sowie Aceton jedoch schwer löslich ist. Die Substanz enthält 18, o % Cholesterin, 1, 4 5 #lo N, 2, o 8 % P. Säurezahl 27,0, Verseifungszahl 96,8. In a further development of this process it has now been found that one can advantageously proceed in such a way that the body fluids with fat-dissolving, surface-active liquids or liquid mixtures of low water solubility, together with water-soluble, surface-active St #, which do not chemically with the constituents of the body fluids react, or treated with water, fat-dissolving fluids were less or no surface activity. Examples i. iol of cerebral press juice are treated at pii 5, o with a mixture of 5 o cc of decyl alcohol and 5 o cc of xylene; After air has been passed through for 3 hours, the liquid lipoid-alcohol mixture is separated off by centrifugation. After the alcohol has evaporated, the lipoid remains as a light brown, waxy mass that easily dissolves in benzene, ether, xylene, CI-il, or, oform, methylene chloride, but is sparingly soluble in methyl and ethyl alcohol and acetone. The substance contains 18% cholesterol o, 1, 4, 5 #lo N, 2, 8% o P. acid number 27.0, saponification 96.8.

2. Werden i o 1 Hirnsaft mit 6 g Polväthylenglyk#ololcyläther, 5o ccm Xylol unä 5o ccm Heptylalkohol versetzt, so erhält man nach 3stündigem Durchleiten von L - uft das Lipoid aus der durch Zentrifugieren abgesehiedenen und im Vakuum eingedunsteten- Extraktionsflüssigkeit. Das so gewonnene Lipoid besitzt die in Beispiel i beschriebene Löslichkeit, Es enthält 18,3 o,/o Cholesterin i (),'o _X i,ggoilo P. Säurezahl 26,5, gsz41, 98,3- 'N#äu!7 f* 3. iol Pferdeserurn von der ,5 e werden mit ioo ccm eines Gemi# cÜes von Oktyl-, Nonyl- und Decylalkohol vom Siedepu:nkt 195 bis --o5' versetzt, ferner werden 309 Polyäthylenglyk-ololeyläther hinzugefügt und nach 2Stündigem Schütteln die ölige alkoholische Oberschicht abgehoben. Das Lipoid fällt aus derselben -nach Verdunsten des Alkohols und nach Entfernung anhaftendenPolyäthylenglyk#ololeyläther mittels Ätherausfällung als gelbliches, halbfestes Produkt an, das in Aceton und Äthylalkohol schwerer, leicht dagegen in Petroläther, Chloroform, Benzol, Äther und Methylenchlorid löslich ist. N-Gehalt 0,570/0, P-Gehalt 0,7190,10, Cholesteringehalt 300/0, Verseifungszahl ioi,5, Säurezahl 18,o.2. If io 1 brain juice with 6 g Polväthylenglyk # ololcyläther, 5o cc xylene UNAE 5o cc heptyl offset so obtained after 3 hours by passing L - runs the Lipoic from the abgesehiedenen by centrifugation and vacuum extraction liquid eingedunsteten-. The lipoid obtained in this way has the solubility described in Example i, It contains 1 8.3 o, / o cholesterol i (), 'o _X i, ggoilo P. acid number 26.5, gsz41, 98.3- 'N # äu! 7 f * 3rd iol horse serum from the , 5 e are made with 100 cc of a Gemi # cÜ Octyl, nonyl and decyl alcohol with a boiling point of 195 to --o5 'are added, 309 polyethylene glycol ololeyl ether is added and, after shaking for 2 hours, the oily alcoholic top layer is lifted off. After evaporation of the alcohol and after removal of adhering polyethylene glycol ololeyl ether by means of ether precipitation, the lipoid is obtained as a yellowish, semi-solid product which is more difficult to dissolve in acetone and ethyl alcohol, but easily soluble in petroleum ether, chloroform, benzene, ether and methylene chloride. N content 0.570 / 0, P content 0.7190.10, cholesterol content 300/0, saponification number ioi, 5, acid number 18, o.
