Das erfindungsgemäße Reinigungsverfahren sei an Hand folgender Beispiele noch näher erläutert:The cleaning method according to the invention will be explained in more detail using the following examples:
100 g handelsübliches Sojabohnenrohphosphatid mit einem Phosphatidylcholingehalt von 19,5% werden in 1,51 Methylenchlorid oder Methylenchlorid-Äthanol (95 : 5) gelöst und mit 500 g Aluminiumoxyd 1 Stunde kräftig gerührt. Nach der Trennung vom Adsorbens wird einige Male mit etwa 300 ml Methylenchlorid oder Methylenchlorid-Äthanol (95 : 5) kurz aufgerührt und jedesmal vom Lösungsmittel getrennt. Die so erhaltenen Lösungen werden vereinigt und auf vorgenannte Weise mit weiteren 500 g Aluminiumoxyd behandelt. Die gesamten Lösungen werden vereinigt, und das Lösungsmittel wird abdestilliert. Es bleiben 34 g = 34% eines stark gelbgefärbten Öls zurück. Der Aluminiumoxydrückstand des ersten Rührvorganges wird sofort mit etwa 800 ml Äthanol einige Minuten gerührt und abdekantiert. Das Auswaschen und Dekantieren wird noch 2- bis 3mal wiederholt. Die alkoholischen Lösungen werden vereinigt, dann zu dem Aluminiumoxyd des zweiten Rührvorganges gegeben und etwa 15 Minuten lang kräftig gerührt. Nach der Trennung wird das zurückbleibende Aluminiumoxyd mit jeweils etwa 300 ml Äthanol wiederholt ausgewaschen und dekantiert. Alle alkoholischen Lösungen werden vereinigt und durch Destillation im Vakuum unter dem Schutz eines inerten Gases vom Lösungsmittel befreit. Es bleibt ein praktisch kephalinfreies, annähernd reines Phosphatidylcholin zurück, ίο Ausbeute: 13 g = 67%.100 g of commercially available raw soybean phosphatide with a phosphatidylcholine content of 19.5% dissolved in 1.5 l of methylene chloride or methylene chloride-ethanol (95: 5) and treated with 500 g of aluminum oxide for 1 hour vigorously stirred. After the adsorbent has been separated, it is mixed with about 300 ml of methylene chloride a few times or methylene chloride-ethanol (95: 5) briefly stirred up and separated from the solvent each time. The so obtained Solutions are combined and added in the aforementioned manner with a further 500 g of aluminum oxide treated. All of the solutions are combined and the solvent is distilled off. It stays 34 g = 34% of a strongly yellow-colored oil. The aluminum oxide residue from the first stirring process is immediately stirred with about 800 ml of ethanol for a few minutes and decanted off. The washing out and decanting is repeated 2 to 3 more times. The alcoholic solutions are combined, then added to the aluminum oxide of the second stirring process and stirred vigorously for about 15 minutes. After the separation, the remaining aluminum oxide is repeated with about 300 ml of ethanol each time washed out and decanted. All alcoholic solutions are combined and distilled in Vacuum freed from the solvent under the protection of an inert gas. It remains a practically cephalin-free, almost pure phosphatidylcholine back, ίο yield: 13 g = 67%.
100 g Sojabohnenrohphosphatid anderer Provenienz mit 20,5 % Phosphatidylcholingehalt werden in 2 1100 g of raw soybean phosphatide of another provenance with 20.5% phosphatidylcholine content are used in 2 1
Essigester mit 5% Dichloräthanzusatz gelöst und zweimal mit je 300 g Aluminiumoxyd für eine Stunde gerührt und wie unter Beispiel 1 beschrieben weiterverarbeitet. Das Auswaschen der Neutraliipide erfolgt mit Essigester-Dichloräthan (95: 5). Ausbeute nach dem Abdampfen des Lösungsmittels 29 g = 29 %. Die cholinhaltige Glycerinphosphatidfraktion wird wie im Beispiel 1 mit Äthanol gewonnen. Ausbeute nach dem Abdestillieren des Lösungsmittels im Vakuum unter Nachziehen eines inerten Gases 12,5 gDissolved ethyl acetate with 5% dichloroethane additive and twice with 300 g of aluminum oxide each time for one hour stirred and further processed as described in Example 1. The neutral lipids are washed out with ethyl acetate dichloroethane (95: 5). Yield after evaporation of the solvent 29 g = 29%. The choline-containing glycerol phosphatide fraction is obtained as in Example 1 with ethanol. yield after distilling off the solvent in vacuo while an inert gas is drawn in, 12.5 g
2S =61%. 2 S = 61%.
60 g handelsübliches Rohphosphatid aus Sojabohnen mit 20% Phosphatidylcholingehalt werden in 1160 g of commercially available rock phosphatide from soybeans with 20% phosphatidylcholine content are used in 11
Dichloräthan oder Dichloräthan-Äthanol (95: 5) gelöst und zweimal mit je 360 g Aluminiumoxyd wie im Beispiel 1 für je 1 Stunde gerührt und aufgearbeitet. Zur Abtrennung der Neutrallipide wird wenigstens dreimal mit je 200 ml Dichloräthan-Äthanol (95 : 5) ausgewaschen. Ausbeute an Neutrallipiden nach Abdampfen des Lösungsmittels 18,8 g = 31%. Die Aluminiumoxydrückstände werden 3- bis 4mal mit je 200 ml Äthanol wie unter Beispiel 1 beschrieben ausgewaschen. Aus den vereinigten äthanolischen Lösungen fällt die hochreine Phosphatidylfraktion in einer Menge von 7,2 g an. Das entspricht einer Ausbeute von 60 %.Dissolved dichloroethane or dichloroethane-ethanol (95: 5) and stirred and worked up twice with 360 g of aluminum oxide as in Example 1 for 1 hour each time. To separate the neutral lipids, at least three times with 200 ml dichloroethane-ethanol (95: 5) washed out. Yield of neutral lipids after evaporation of the solvent 18.8 g = 31%. the Aluminum oxide residues are treated 3 to 4 times with 200 ml of ethanol each time as described in Example 1 washed out. The highly pure phosphatidyl fraction falls from the combined ethanolic solutions an amount of 7.2 g. This corresponds to a yield of 60%.
50 g Sojabohnenrohphosphatid mit 20 % Phosphatidylcholingehalt werden unter Zusatz von 0,1 g Alphatocopherol in 11 Essigester unter gelindem Erwärmen gelöst, wenn notwendig von nichtlipidartigen Verunreinigungen durch Filtration befreit und bei etwa 37° C mit 800 g basischem Aluminiumoxyd (Aktivitätsstufe 1) 1,5 bis 2 Stunden kräftig gerührt. Nach der Trennung vom Adsorbens wird das Aluminiumoxyd mehrmals mit insgesamt etwa 8,5 1 Essigester-Äthanol (94: 6) ausgewaschen. Die gesamten Lösungen werden vereinigt und das Lösungsmittel abdestilliert. Es fallen 16 g = 32% öl an. Der Aluminiumoxydrückstand wird mit etwa 3 bis 41 Äthanol mehrmals ausgewaschen, die alkoholischen Lösungen vereinigt und das Lösungsmittel durch Destillation im Vakuum unter dem Schutz eines inerten Gases abgezogen. Es resultiert eine hochgereinigte, fast kephalinfreie Phosphatidylcholinfraktion in einer Ausbeute von 6,5 g = 65%.50 g of raw soybean phosphatide with 20% phosphatidylcholine content are added with 0.1 g of alphatocopherol dissolved in 11 ethyl acetate with gentle warming, if necessary from non-lipid-like impurities freed by filtration and stirred vigorously at about 37 ° C. with 800 g of basic aluminum oxide (activity level 1) for 1.5 to 2 hours. After The aluminum oxide is separated from the adsorbent several times with a total of about 8.5 1 ethyl acetate-ethanol (94: 6) washed out. All of the solutions are combined and the solvent is distilled off. It fall 16 g = 32% oil. The aluminum oxide residue is washed out several times with about 3 to 41 ethanol, the alcoholic solutions are combined and the solvent is removed by distillation in vacuo withdrawn from the protection of an inert gas. The result is a highly purified, almost cephalin-free phosphatidylcholine fraction in a yield of 6.5 g = 65%.

phosphorsäurediglyceridesterfreien natürlichen Cholin- Beim Lösen des Rohphosphatids kann man auch phosphorsäurediglyceridestern durch Säulenchromato- Essigester oder einen dichlorierten Kohlenwasserstoff graphie bekannt, wobei als Adsorbens unter anderem 65 bzw. eine Mischung dieser Lösungsmittel in Gegen-Aluminiumoxyd verwendet wird. Auch hierbei wird wart von bis zu 6 Volumprozent Alkohol verwenden, ein alkoholischer Extrakt des vorher entölten Roh- wobei das Aluminiumoxyd vor dem Eluieren mit dem phosphatide verwendet. Diese vorherige Entölung, Alkohol noch mit einem der ursprünglich verwendetenThe USA.-Patent 2 945 869 is a cleaning It was not foreseeable that the oil content of the process for the production of soy phosphatide fraction 4 ° Phosphatidgemisches the adsorption of Phosphatide functions known, as emulsifiers for intravenous to the aluminum oxide and that applying fat emulsions are to be used. After changing the solvent, alcoholic solutions of the desired separation of the various de-oiled or heavily oil-depleted rock phosphatides are immediately activated Kephalin ßes elution of the aluminum oxide with the alcohol, to deplete and, above all, largely to free from the inositol. When carrying out the inventive method, the phosphatides, which, when administered intravenously, will lower the blood pressure of the aluminum oxide after suspending and stirring application to the cat call in the rock phosphatide solution. However, this process requires first 50 aluminum separated by decanting or the like, deoiling of the commercially available rock phosphatides, oxide stirred with alcohol for a few minutes, and then extraction with alcohol, whereupon the aiko is then separated in the decanter. The washing out of holic solutions with the adsorbent with little alcohol can be repeated again, materials are treated. Whether here and the separated aluminum oxide, which contains the undie treatment via an aluminum oxide column or the desired accompanying substances, is discarded by slurrying aluminum oxide through or worked up on this. The procedural results are irrelevant. The result is alcoholic solutions that are always retained are then freed from the solvent by a phosphatidylcholine of a maximum of 70% pure distillation in vacuo. Further or even complete freedom from cephalins In this case, a highly pure, cephalin-free or could not be achieved by this method. 60 severely depleted fraction of natural choline-From the own German patent specification 1,053,299 containing glycerol phosphatides with a content of is also a process for the production of colamin-90% and more phosphatidylcholine.
Phosphoric acid diglyceride ester-free natural choline- When dissolving the raw phosphatide one can also use phosphoric acid diglyceride esters by column chromatography, ethyl acetate or a dichlorinated hydrocarbon known, whereby the adsorbent used is, inter alia, 65 or a mixture of these solvents in counter-aluminum oxide. Here, too, up to 6 percent alcohol by volume is used, an alcoholic extract of the previously de-oiled crude, whereby the aluminum oxide is used before eluting with the phosphatide. This previous de-oiling, alcohol still with one of the originally used
