Description
Verfahren zur Herstellung von adstringierend wirkenden Gerbstoff-Eiweißverbindungen Die bisher in der Medizin verwandten Tannin-Eiweißpräparate verfolgten den Zweck, die an Eiweiß .gebundene Gerbsäure nicht im Magen, sondern erst im alkalischen Darmsaft in Freiheit treten zu lassen. Tatsächlich wird bei den bisher bekannten Präparaten. jedoch schon im neutralen und sauren Medium Gerbsäure abgespalten, so daß nur ein Teil des Gerbstoffes im unteren Darmabschnitt zur Einwirkung gelangt (vgl. Pharmazeut. Presse i93'5, S. tob; Journ. of pharmacology and experimental therap.eutics, Bd. 17, S. 86 [192I]).Process for the production of astringent tannin-protein compounds The tannin-protein preparations previously used in medicine had the purpose of releasing the tannic acid bound to protein not in the stomach, but only in the alkaline intestinal juice. In fact, with the previously known preparations. However, tannic acid is already split off in the neutral and acidic medium, so that only part of the tannin comes into play in the lower intestinal section (cf. Pharmazeut. Presse 193'5, p. tob; Journ. of pharmacology and experimental therap.eutics, vol. 17 , P. 86 [192I]).
Es wurde nun gefunden, daß man durch Einwirkung von gerbstofhaltigen Holzextrakten, insbesondere Fichternholzgerbstoffextrakten, die zu etwa gooio aus L ggninsulfosäure bestehen und gegebenenfalls mit wenig Kresol teilkondensiert sind, auf Eiweiß, tierischen und pflanzlichen Ursprungs, wie Fischeiweiß, Vogeleiweiß, Milcheiweiß, Sojaeiweiß und ähnliche Sorten, bräunliche geruch- und geschmacklose sowie völlig ungiftige Gerbstoff-Eiweißverbindungen erhält, die in Aussehen und Verhalten den bisher in der Medizin verwandten Tannin-Eiweißverbindungen ähnlich sind, wenn man die Einwirkung bei pH i bis 2 und einer Temperatur der Lösungen von 2o bis i oo° vornimmt sowie die gebildeten Gerbstoff-Eiweißverbindimgen nach dem Abtrennen von den Mutterlaugen längere Zeit an der Luft trocknet und dann einige Stunden bei 1200 nachhärtet. Die so erhaltenen neuen Gerbstoff-Eiweißverbindungen spalten weder im sauren noch im neutralen, sondern erst im alkalischen Medium den Gerbstoff ab, der dann restlos zur physiologischen Wirkung kommt.It has now been found that by the action of tannin-containing Wood extracts, especially spruce tannin extracts, which result in about gooio L consist of ggnine sulfonic acid and possibly partially condensed with a little cresol, on protein, of animal and vegetable origin, such as fish protein, bird protein, Milk protein, soy protein and similar varieties, brownish odorless and tasteless as well as completely non-toxic tannin-protein compounds, which in appearance and Behavior similar to the tannin protein compounds previously used in medicine are, if one has the action at pH i to 2 and a temperature of the solutions of 2o to 10o ° and the tannin-protein compounds formed after Separate from the mother liquors for a long time in the air and then dry some Post-cures at 1200 hours. The new tannin-protein compounds obtained in this way split neither in the acidic nor in the neutral, but only in the alkaline medium The tannin, which then has a completely physiological effect.
Im Vergleich mit den bisher verwandten Gerbstoff-Eiweißverbindungen aus Tannin und Vogel- oder anderem Eiweiß besitzen die neu gefundenen Verbindungen mindestens die doppelte, günstigstenfalls die 7fache Wirksamkeit. Beispiel i 50 g Milcheiweiß werden mit 5oo ccm Wasser verrührt und im Wasserbad auf 35- erwärmt. Hierzu wird eine Lösung von Sog Fichtenholzgerbstofextrakt in 450 ccm Wasser in dünnem Strahl unter ständigem Rühren gegeben, allmählich auf q.5- erwärmt und durch Zugabe von Salzsäure auf pH i,8 bis 2 eingestellt. Nach ,etwa einstündigem Rühren und Stehen über Nacht wird abgesaugt, luftgetrocknet und bei i2o- nachgehärtet. Ausbeute 59 g. Die Verbindung spaltet im sauren Medium keinen Gerbstoff ab, im neutralen Medium Spuren; im alkalischen Medium wird die gesamte vorhandene adstringierende Substanz abgespalten. Beispiel 2 5oog Milcheiweiß werden mit 51 Wasser verrührt und im Wasserbad auf 35- erwärmt; hierzu wird eine Lösung von 5oog mit zvciii@ liresol teilkondensiertem Fichtenholzgeri)-stoffextrakt in 45oo ccm Wasser in dünn_m Strahl unter ständigem Rühren zugefügt, allmählich auf 45' erwärmt und durch Zugabe von Salzsäure auf PH 2 eingestellt. Nach etwa einstündigem Rühren und Stehen über Nacht wird abgesaugt, luftgetrocknet und bei i 2onachgehärtet. Ausbeute etwa 515 g. Die Verbindung spaltet weder im sauren noch neutralen Medium adstringierende Substanz ab, dagegen wird der gesamte Gerbstoff im alkalischen Medium abgegeben. Beispiel 3 i k,- Milcheiweiß werden mit lol Wasser verrührt und im Wasserbad auf 4o= erwärmt; hierzu wird eine Lösung von 61,-- mit wenig Kresol teilkondensiertem Fichtenholzgerbstoffextrakt in 6o 1 Wasser in dünnem Strahl unter ständigem Rühren gegeben. Durch Zugabe von Salzsäure wird das Gemisch auf PH 2 gebracht und allmählich unter ständigem Rühren bis auf 95- erhitzt. Nach dem Stehen über Nacht wird abgesaugt, luftgetrocknet und bei 120- nachgehärtet. Ausbeute etwa 1,40o kg. Die Verbindung spaltet weder im sauren noch neutralen Medium adstringierende Substanz ab, dagegen wird der gesamte Qerbstoff im alkalischen Medium abgespalten. Beispiel q. 5o g Fischeiweiß werden mit 50o ccm Wasser verrührt und im Wasserbad auf 35- erwärmt. Hierzu wird eine Lösung von 5o g rnit wenig Kresol teilkondensiertem Fichtenholzgerbstoffextrakt in q.5occm Wasser in dünnem Strahl unter ständigem Rühren zugefügt. Allmählich wird auf 45 bis 5o- erwärmt, durch Zugabe von Salzsäure auf pH 1,S bis 2 eingestellt. Nach etwa einstündigem lühren und Stehen über Nacht wird abgesaugt, luftgetrocknet und bei 12o- nachgehärtet. Ausbeute -etwa 55g. Beispiel 5 5o g Sojaeiweiß werden mit 5oo ccm Was. ser verrührt und im Wasserbad auf 35- erwärmt. Hierzu wird eine Lösung von Sog mit wenig Kresol teilkondensiertem Fichtenholzgerbstoffextrakt in 45o ccm Wasser in dünnem Strahl unter ständigem Rühren gegeben. Allmählich wird auf So- erwärmt, durch Zugabe von Salzsäure auf pH i,8 bis 2 eingestellt, nachetwa einstündigem Rühren und Stehen über Nacht abgesaugt, luftgetrocknet und bei j 2o nachgehärtet. Ausbeute etwa 48 g'Compared with the previously used tannin-protein compounds from tannin and bird or other protein, the newly found compounds have at least twice, at best 7 times the effectiveness. Example i 50 g of milk protein are stirred with 500 ccm of water and heated to 35 ° in a water bath. For this purpose, a solution of suction spruce tanning extract in 450 ccm of water is added in a thin stream with constant stirring, gradually warmed to q.5- and adjusted to pH 1.8 to 2 by adding hydrochloric acid. After stirring for about one hour and standing overnight, it is suctioned off, air-dried and post-cured at i2o. Yield 59g. The compound does not split off any tannin in the acidic medium, but traces in the neutral medium; in the alkaline medium all the astringent substance present is split off. Example 2 50000 milk protein are mixed with water and heated to 35% in a water bath; To this end, a solution of 50 og with zvciii @ liresol partially condensed spruce framework extract in 45oo ccm of water is added in a thin stream with constant stirring, gradually warmed to 45 'and adjusted to pH 2 by adding hydrochloric acid. After stirring for about one hour and standing overnight, the mixture is filtered off with suction, air-dried and post-cured at 12on. Yield about 515 g. The compound does not split off any astringent substance in either an acidic or neutral medium; on the other hand, all of the tannin is released in an alkaline medium. Example 3 ik, - milk proteins are mixed with 1ol water and heated to 40 = in a water bath; A solution of 61 is - teilkondensiertem with little cresol Fichtenholzgerbstoffextrakt in 6o 1 water in a thin stream with continuous stirring. The mixture is brought to pH 2 by adding hydrochloric acid and gradually heated to 95% with constant stirring. After standing overnight, it is suctioned off, air-dried and post-cured at 120-. Yield about 1.40 kg. The compound does not split off astringent substance in either acidic or neutral medium, on the other hand all herb is split off in alkaline medium. Example q. 50 g of fish protein are mixed with 50 ° cc of water and heated to 35 ° in a water bath. To this end, a solution of 50 g of spruce tanning agent extract partially condensed with a little cresol is added in a thin stream with constant stirring. Gradually, the temperature is raised to 45 to 50 and the pH is adjusted to 1.5 to 2 by adding hydrochloric acid. After stirring for about an hour and standing overnight, it is suctioned off, air-dried and post-cured at 120. Yield - about 55g. Example 5 50 g of soy protein are added to 500 ccm of water. water stirred and warmed to 35- in a water bath. For this purpose, a solution of suction with a little cresol partially condensed spruce wood tannin extract in 45o ccm of water is added in a thin stream with constant stirring. It is gradually warmed to so, adjusted to pH 1.8 to 2 by adding hydrochloric acid, and after stirring for about one hour and standing overnight, it is filtered off with suction, air-dried and post-cured at j 20. Yield about 48 g '
