Description
Verfahren zur Gewinnung von reinen PhosphatidenProcess for the production of pure phosphatides
Das bei der Speiseölherstellung anfallende pflanzliche Rohlecithin enthält ebenso wie aus tierischem Gewebe gewonnes neben Phosphatidylcholin, Phosphatidyläthanolamin, Phosphatidylinosit und anderen phosphorhaltigen Glycerinester Begleitsubstanzen wie Peptide, Aminosäuren, Sterine, Sterinester, Mono-, und Di-und Triglyceride, freie Fettsäuren und Kohlenhydratderivate.The raw vegetable lecithin produced in the production of edible oil as well as obtained from animal tissue, contains phosphatidylcholine, phosphatidylethanolamine, Phosphatidylinositol and other phosphorus-containing glycerol esters accompanying substances such as peptides, amino acids, sterols, sterol esters, mono-, and di- and triglycerides, free fatty acids and carbohydrate derivatives.
Diese Begleitsubstanzen sind sowohl für pharmazeutische als auch lebensmittel technische Anwendungen unerwünscht bzw. schädlich.These accompanying substances are common to both pharmaceutical and food products technical applications undesirable or harmful.
Die übliche Reinigung sieht eine Behandlung mit Aceton zur Abtrennung von Neutrallipiden vor. Dabei bleiben weiterhin die Sterinderivate sowie Kohlenhydrate und Peptide als unerwünschte Begleitsubstanzen mit den Phosphatiden vergesellschaftet.The usual cleaning involves treatment with acetone for separation of neutral lipids. The sterol derivatives and carbohydrates still remain and peptides associated with the phosphatides as undesirable accompanying substances.
Daran schliesst sich üblicherweise eine ein oder mehrmalige Extraktion mit niederen Alkoholen wie Methanol, Athanol, Propanol etc.This is usually followed by one or more extraction with lower alcohols such as methanol, ethanol, propanol etc.
an wie dies z.B. in den Patenten U.S. 1.955.514 und Ger. 261.212 beschrieben ist.as shown, for example, in U.S. patents. 1.955.514 and Ger. 261.212 is.
Hierbei lassen sich zwar Kohlenhydrate und Peptide abtrennen, aber nicht die Sterinderivate.Carbohydrates and peptides can be separated here, but not the sterol derivatives.
Zur Gewinnung von sterinfreien Phosphatiden, insbesondere Phosphatidylcholin, erfolgt die weitere Reinigung durch chromatographische Methoden mit Kieselgel, Aluminiumoxid, Florisil, lonenaustauscher oder andere Materialien (12.01.73 JA 006399 und U.S. 2.554.955) Dies kann sowohl säulenchromatographisch als auch durch Rühren rnit der Trennmaterial erFrlrjeti (DT - 61/6/9) Die am meisten benutzte Methode sieht eine säulenchromatograpische Reinigungmit Kiese gel als Trennmaterial vor. Das Verhältnis von Trennmaterial zu Rohprodukt liegt ülicherweise zwischen 100 : 1.For obtaining sterol-free phosphatides, especially phosphatidylcholine, further purification is carried out by chromatographic methods with silica gel, aluminum oxide, Florisil, ion exchange or other materials (1/12/73 JA 006399 and U.S. 2.554.955) This can be done both by column chromatography and by stirring with the Release material erFrlrjeti (DT - 61/6/9) The most widely used method sees one purification by column chromatography with silica gel as separating material. The relationship from separating material to raw product is usually between 100: 1.
und 10 : 1. Zur Elution benutzt man Lösungsmittelgradienten aus chlorierten Kohlenwasserstoffen, wie Methylenchlorid, Chloroform, DichToräthan etc. und niedere Alkohole, wie Methanol, Athanol usw. Es werden so in der Reihenfolge ihrer Polarität zuerst die Neutrallipide, die Sterinderivate und erst am Schluss die Phospholipide eluiert.and 10: 1. Chlorinated solvent gradients are used for elution Hydrocarbons such as methylene chloride, chloroform, dichloroethane, etc. and lower Alcohols such as methanol, ethanol etc. They are so in the order of their polarity first the neutral lipids, the sterol derivatives and only at the end the phospholipids eluted.
Das Verhältnis Ausgangsmaterial (g) zu Lösungsmittel (Vol.) beträgt 1 : 50 bis 1 : 200.The ratio of starting material (g) to solvent (by volume) is 1: 50 to 1: 200.
Man kann auf diese Art und Weise nur kleine Mengen Rohmaterial reinigen und benötigt zusätzlich grosse Mengen an verschiedenen Lösungsmittelgemischen.You can only clean small amounts of raw material in this way and also requires large amounts of different solvent mixtures.
Es wurde nun überraschenderweise gefunden, dass man die Phosphatide in einem Arbeitsschritt von sämtlichen Begleitstoffen wie Peptide, Kohlenhydrate, Mono-, Di- und Triglyceride, Fettsäuren sowie Sterinderivate durch ein säulenchromatographisches Verfahren befreien kann.It has now surprisingly been found that the phosphatides in one step of all accompanying substances such as peptides, carbohydrates, Mono-, di- and triglycerides, fatty acids and sterol derivatives by means of column chromatography Procedure can exempt.
Verfahrensgemäss wird dabei das Trennmaterial, z.B. Kieselgel, mit einem unpolaren Lösungsmittel wie Kohlenwasserstoff oder Kohlenwasserstoffgemischen in die Säule gefüllt.According to the method, the separating material, e.g. silica gel, is included a non-polar solvent such as hydrocarbon or hydrocarbon mixtures filled into the column.
Im Gegensatz zu allen bisher üblichen Säulenchromatographiemethoden ist verfahrensgemäss das Trennmaterial - Rohprodukt Verhältnis zwischen 1,5 : 1 und 3 : 1.In contrast to all previously common column chromatography methods According to the process, the separation material - raw product ratio is between 1.5: 1 and 3: 1.
Zu erwarten war unter diesen Bedingungen, dass keinerlei Trennungseigenschaften mehr vorhanden waren und das ölhaltige Rohprodukt unverändert von der Säule heruntergewaschen würde.Under these conditions it was to be expected that no separation properties whatsoever were more present and the oily crude product was washed down unchanged from the column would.
Verfährt man erfindungsgemäss jedoch so, dass man mit einem einzigen unpolaren Lösungsmittel, wie Kohlenwasserstoffen, deren Gemische, Ather etc. eluiert, so erhält man eine saubere Trennung in der Form, dass im Gegensatz zu den bisher bekannten Verfahren ausschliesslich die Phosphatide wie Phosphatidyicholin, Phosphatidyläthanolamin, Phosphatidylinosit sowie sonstige Phosphatidylderivate eluiert werden und alle anderen Begleitstoffe wie Mono-, Di- und Triglyceride, Fettsäuren, Kohlenhydrate, Peptide sowie insbesondere Sterinderivate auf der Säule verbleiben.If one proceeds according to the invention, however, that one with a single non-polar solvents, such as hydrocarbons, their mixtures, ethers etc. elute, so you get a clean separation in the form that in contrast to the previous one known processes exclusively the phosphatides such as phosphatidyicholine, phosphatidylethanolamine, Phosphatidylinositol and other phosphatidyl derivatives are eluted and all others Accompanying substances such as mono-, di- and Triglycerides, fatty acids, carbohydrates, Peptides and especially sterol derivatives remain on the column.
tm Gegensatz zu den bisher bekannten Verfahren braucht man für ein Teil(g) Rohprodukt nur 5 - 8 Teile (Vol.) Elutionsmittel.In contrast to the previously known method, one needs for a Part (g) of crude product only 5 - 8 parts (vol.) Of eluent.
Man erhält also in einem, statt bisher mehreren Verfahrensschritten bei sehr viel geringerem Verbrauch eines einzigen Lösungsmittels ein reineres Produkt.So you get in one, instead of previously several process steps a purer product with a much lower consumption of a single solvent.
Weiterhin ist es verfahrensgemäss möglich, bifreie Phosphatidgemische von ihren Begleitstoffen zu trennen, indem man ihnen zwischen 20 % und 40 % an pflanzlichem 01 zusetzt und dann wie beschrIeben verfährt.Furthermore, according to the method, it is possible to use bi-free phosphatide mixtures to separate them from their accompanying substances by adding between 20% and 40% vegetable 01 is added and then proceed as described.
Weiterhin ist es verfahrensgemäss auch möglich, zuerst die Säule durch Zugabe von 20 - 40 % an pflanzlichem Öl so zu präparieren, dass bei einer anschliessenden Chromatographie eines ölfreien Phosphatidgemisches wiederum nur die Phosphatide und nicht die Begleitstoffe eluiert werden. Die Phosphatidausbeuten erreichen bei dem hier vorliegenden Verfahren bis zu 95 %.Furthermore, according to the method, it is also possible to first go through the column Add 20 - 40% of vegetable oil to prepare so that a subsequent Chromatography of an oil-free phosphatide mixture, in turn, only contains the phosphatides and the accompanying substances are not eluted. The phosphatide yields reach at the present process up to 95%.
Beispiele: Beispiel 1 100 g Kieselgel werden in 300 ml Petroläther aufgeschlämmt und in eine Chromatographiesäule (Durchmesser 4 cm) gefüllt. Man löst 50 g Rohphosphatid in 150 ml Petroläther und gibt die Lösung auf die vorbereitete Säule. Eluiert wird mit Petroläther,die einzelnen Fraktionen ä 50 ml werden über DC geprüft.Examples: Example 1 100 g of silica gel are dissolved in 300 ml of petroleum ether slurried and filled into a chromatography column (diameter 4 cm). One solves 50 g of rock phosphatide in 150 ml of petroleum ether and add the solution to the prepared Pillar. It is eluted with petroleum ether, the individual 50 ml fractions are over DC checked.
Es werden 5 Fraktionen eingedampft, die 01- und Sterin-frei sind: Man erhält 30 g Phosphatid.5 fractions are evaporated, which are 01- and sterol-free: 30 g of phosphatide are obtained.
Dies entspricht einer Ausbeute von 92,3 /00, bezogen auf die Phosphatide im Rohphosphatid t65 % Phosphatide, 35 % Dialysierba res3.This corresponds to a yield of 92.3 / 00, based on the phosphatides in the rock phosphatide t65% phosphatide, 35% dialysable res3.
Beispiel 2 Wie unter Beispiel 1 nimmt man 100 g Kieselgel, füllt eine Säule und gibt dann 50 g eines ölhaltigen Rohphosphatidextraktionsrückstandes, die in 100 ml Petroläther gelöst sind, auf die Säule.Example 2 As in Example 1, 100 g of silica gel are taken and one is filled Column and then gives 50 g of an oil-containing raw phosphatide extraction residue that are dissolved in 100 ml of petroleum ether on the column.
Man erhält 30 g sauberes Produkt aus 5 Fraktionen. Dies entspricht einer Ausbeute von 92,3 %.30 g of clean product are obtained from 5 fractions. This matches with a yield of 92.3%.
Beispiel 3 450 g eines ölhaltigen Rohphosphatidextraktionsrückstandes werden in 1350 ml Petroläther (Kp.: 40 - 600C) gelöst und mit Hilfe von Celite Perlite J 100 filtriert. Das Filtrat wird auf eine vorbereitete 900 g-Kieselgelsäule gegeben. Eluiert wird mit Petroläther.Example 3 450 g of an oil-containing rock phosphatide extraction residue are dissolved in 1350 ml of petroleum ether (boiling point: 40-600C) and perlite with the help of Celite J 100 filtered. The filtrate is placed on a prepared 900 g silica gel column. It is eluted with petroleum ether.
Nach 5 Fraktionen ã 500 ml ist im Eluat kein Phosphatid mehr auf der DC-Platte zu sehen.After 5 fractions of 500 ml each, there is no longer any phosphatide in the eluate TLC plate to see.
Nach Eindampfen der Lösungen erhält man 275,48 g Produkt, dies enspricht 94,58 t der Theorie.After evaporation of the solutions, 275.48 g of product are obtained, this corresponds 94.58 t of theory.
Beispiel 4 100 g Kieselgel werden in 300 ml Petroläther (Hexan) rein (Kp.: 40 - 600C) aufgeschlämmt und in eine Chromatographtesäule von einem Durchmesser von 4 cm gefüllt.Example 4 100 g of silica gel are pure in 300 ml of petroleum ether (hexane) (Bp .: 40-600C) slurried and placed in a chromatograph column of a diameter of 4 cm filled.
16 g Soja-U1 roh werden in 20 ml Hexan gelöst und auf die vorbereitete Säule gegeben. Man lässteseinsickern und wäscht mit 50 ml Hexan nach. Dann gibt man 30 g entöltes Rohphosphatid, die in 50 ml Hexan gelöst sind, auf die Säule und eluiert mit Hexan.16 g of raw soy U1 are dissolved in 20 ml of hexane and added to the prepared Given column. It is allowed to seep in and washed with 50 ml of hexane. Then there one 30 g of deoiled rock phosphatide, which are dissolved in 50 ml of hexane, on the column and eluted with hexane.
Man fängt Fraktionen von 50 ml auf und prüft diese über Dünnschichtchromatographie. Ab der 5. Fraktion wird kein Phosphatid mehr eluiert, die Fraktionen 1 - 4 sind Cl- und Sterin-frei.Fractions of 50 ml are collected and checked by thin layer chromatography. From the 5th fraction onwards, no more phosphatide is eluted, fractions 1 - 4 are Cl- and sterol-free.
Die Fraktionen werden eingedampft. Man erhält 24,69 g Phosphatid. Dies entspricht einer Ausbeute von 28,3 t bezogen auf das eingesetzt ERP.The fractions are evaporated. 24.69 g of phosphatide are obtained. This corresponds to a yield of 28.3 t in relation to the ERP used.
Beispiel 5 1500 g Kieselgel werden in 5000 ml Petroläther aufgeschlämmt und in eine Säule gefüllt. 240 g Soja-Ol werden anschliessend in 300 ml Petroläther gelöst und diese Lösung lässt man dann einsickern und wäscht mit 750 ml Petroläther nach.Example 5 1500 g of silica gel are suspended in 5000 ml of petroleum ether and filled into a column. 240 g of soy oil are then poured into 300 ml of petroleum ether dissolved and this solution is then allowed to seep in and washed with 750 ml of petroleum ether after.
Dann gibt man 450 g entöltes Rohphosphatid gelöst in 750 ml Petroläther auf die Säule und eluiert mit Petroläther.Then 450 g of deoiled rock phosphatide dissolved in 750 ml of petroleum ether are added onto the column and elute with petroleum ether.
6 Fraktionen 500 ml ergeben 300 g Phosphatid, dies entspricht einer Ausbeute von 67 t.6 fractions of 500 ml result in 300 g of phosphatide, this corresponds to one Yield of 67 t.
Beispiel 6 50 g eines Gemisches an entöltem Rohphosphatid und Soja-Ol im Verhältnis 65 : 35 werden in 150 ml n-Hexan gelöst und auf eine Säule gegeben, die zuvor mit 100 g Kieselgel, aufgeschlämmt in n-Hexan, gefüllt wird. Dann eluiert man mit n-Hexan.Example 6 50 g of a mixture of deoiled rock phosphatide and soy oil in a ratio of 65:35 are dissolved in 150 ml of n-hexane and placed on a column, which is previously filled with 100 g of silica gel suspended in n-hexane. Then eluted one with n-hexane.
4 Fraktionen à 60 ml werden eingedampft und man erhält 30 g sauberes Produkt, was einer Ausbeute von 92 t entspricht.4 fractions of 60 ml each are evaporated and 30 g of clean material are obtained Product, which corresponds to a yield of 92 t.
Beispiel 7 100 g Kieselgel werden mit 300 ml Petroläther (Kp.: 40 - 600C) aufgeschlämmt und in eine Chromatographie-Säule (Durchmesser 4 cm) gefällt.Example 7 100 g of silica gel are mixed with 300 ml of petroleum ether (boiling point 40 - 600C) slurried and precipitated in a chromatography column (diameter 4 cm).
