Description

Verfähren zum Bleichen gefärbter Extrakte aus Capsicumarten Die für therapeutische Zwecke vielfach benutzten Extrakte der Capsicumarten sind durch die Gegenwart pflanzlicher Farbstoffe und bei der Extraktion und Einengung der Extrakte sich bildender anderer Stoffe stark gefärbt. Je nach der Konzentration schwankt die Farbe von schwarzbraunen bis zu roten und gelben Tönen. Da die Wirkung nur von dem Gehalt an Capsaicin abhängt, bedeutet die Farbe der Extrakte eine unerwünschte Begleiterscheinung.Process for bleaching colored extracts from capsicum species The for Therapeutic purposes are widely used extracts of the capsicum species by the Presence of vegetable dyes and in the extraction and concentration of the extracts other substances that are forming are strongly colored. Depending on the concentration fluctuates the color from black-brown to red and yellow tones. Since the effect is only from Depending on the capsaicin content, the color of the extracts means an undesirable one Accompanying phenomenon.

Versuche, Capsaicin enthaltende Auszüge mit Hilfe von Tierkohle oder Kieselgur zu entfärben, zeigten, daß ein erheblicher Teil des wirksamen Stoffes durch Adsorption verlorengeht. Dagegen führte die Benutzung von Bleicherden, vor allem sauren Bleicherden, zu einem Erfolg. Schüttelt man die Auszüge mit denselben, zweckmäßig unter Erwärmung, so tritt eine weitgehende Bleichung ein, ohne 'daß das Capsaicin verlörengeht.Try making extracts containing capsaicin with the help of animal charcoal or To discolor diatomaceous earth showed that a significant part of the active substance is lost through adsorption. In contrast, the use of bleaching earth demonstrated all acidic bleaching earth, a success. If you shake the extracts with the same, expediently when heated, an extensive bleaching occurs without that Capsaicin is lost.

Eine Möglichkeit, Capsaicin enthaltende Extrakte zu entfärben, bildet besonders aber die Behandlung mit organischen,Peroxyden, wie Benzoylperoxyd und Acetylperoxyd. Diese löst man in den Extrakten; läßt längere Zeit stehen oder erwärmt. Bei Anwendung geeigneter Mengen der Peroxyde werden die Farbstoffe ,gebleicht, während das Capsaicin nur geringfügig angegriffen wird. Dies ist überraschend, denn Capsaicin besitzt im Rest der Decylensäure eine mehrfache Bindung (vgl. Berichte der Deutschen Chemischen Gesellschaft, Jahrgang 63 - 193o - Seite 737f.). Andere Oxydationsmittel, z. B. Kaliump-ermanganat, spalten das Capsaicin völlig auf.One way of decolorizing extracts containing capsaicin is by forming but especially the treatment with organic, peroxides, such as benzoyl peroxide and Acetyl peroxide. These are dissolved in the extracts; lets stand for a long time or warms up. With the use of appropriate amounts of the peroxides, the dyes are bleached while the capsaicin is only slightly attacked. This is surprising because capsaicin has a multiple bond in the rest of the decylenic acid (see reports of the Germans Chemical Society, Volume 63 - 1930 - Page 737f.). Other oxidizing agents, z. B. potassium p-ermanganate, break down the capsaicin completely.

Beide Verfahren lassen sich nun zusammen anwenden. So z. B. erwärmt man zunächst mit den unter dem Namen -Bleicherden bekannten Aluminium-Magnesium-Silikaten, vorteilhaft mit Präparaten, die einen Säureaufschluß durchgemacht haben, und setzt dann ein organisches Peroxyd hinzu.Both methods can now be used together. So z. B. heated one first with the aluminum-magnesium-silicates known under the name -bleaching earth, advantageous with preparations that have undergone acid digestion and sets then add an organic peroxide.

Beispiele i. Ätherischer Extrakt von Chi.llies von dunkelrotbrauner Farbe wird mit z v. H. Beaizoylperoxyd i Stunde lang am Rückflußkühler erwärmt. Nach einigen Minuten beginnt eine Aufhellung, die bis zu hellem Weingelb führt. Das Verfahren kann nochmals wiederholt werden.Examples i. Essential extract of Chi.llies of dark red-brown Color is with z v. H. Beaizoyl peroxide heated under the reflux condenser for 1 hour. After a few minutes a lightening begins, which leads to a light wine yellow. The procedure can be repeated again.

z. Ein Extrakt aus Capsicumfrüchten, hergestellt mit Hilfe von Dichloräthylen, wird i Stunde lang mit 5 Teilen Acetylperoxyd erwärmt. Bereits nach kurzer Zeit Wird der braunschwarze Auszug hellgelb, auch dieser Farbton verschwindet bei längerer Einwirkung des Bleichmittels.z. An extract from capsicum fruits, made with the help of dichloroethylene, is heated for 1 hour with 5 parts of acetyl peroxide. After a short time If the brown-black extract becomes light yellow, this color tone also disappears with longer Exposure to the bleach.

3. Ein Extrakt aus Chillies, mit Hilfe von Kampferöl bereitet, wird etwa i Stunde lang mit iov. H. Bleicherde behandelt. Die filtrierte Flüssigkeit versetzt man nun mit z. v. Il: BenzoylperoXyd und- erwärmt bis zur Lösung desselben. Nach etwa zweistündiger Versuchsdauer- entsteht ein' sehr schwach. -gefärbtes Präparat.3. An extract from chillies, prepared with the help of camphor oil, is made for about an hour with iov. H. Fuller's earth treated. The filtered liquid you now add z. v. II: Benzoyl peroxide and heated until it dissolves. After about two hours of testing, a 'very weak' appears. -stained preparation.

Bei allen so hergestellten Präparaten . ist der Gehalt an Capsaicin vollkommen oder im wesentlichen erhalten geblieben.With all preparations made in this way. is the content of capsaicin completely or substantially preserved.
