Description
Verfahren zur Darstellung von Ergotaminmalat. Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Darstellung des bisher noch unbekannten Salzes des Hauptalkaloides des Mutterkornes, Ergotamin, mit der in pflanzlichen Drogen wehverbreiteten Äpfel säure. Als Ausgangsmaterial kann mann so wohl die reine Base, z.
B. ihre Kristallisation aus wasserhaltigem Aceton, wie sie in Patent Nr. 86321 erwähnt ist, oder ein ergotamin- reiches Alkaloidrohprodukt verwenden und in letzterem Fall die Salzbildung zur Abtren nung des Ergotamins von Begleitstoffen ver wenden.
Das Verfahren zur Darstellung von Er= golaminmalat beruht darauf, dass mann auf Ergotamin eine ausreichende Menge Äpfel säure nach Art der Salzbildung einwirken lässt.
Zur Darstellung von<B>Ei</B> rgotaminmalat in fester kristallisierter Form löst man die freie Base zweckmässig in einem mit Wasser mischbaren, indifferenten, organischen Lö sungsmittel wie Alkohol oder Holzgeist auf und fügt hierauf die Äpfelsäure zu, wodurch die kristallinische Ausscheidung von Ergo taminmalat bewirkt wird.
Man kann auch so verfahren, dass man zu einer Lösung des Ergotamins in mit Wasser nicht mischbaren organischen Lösungsmitteln, wie Äther und Benzol, vorsichtig so lange eine Äpfel säurelösung zusetzt, als noch eine Fäl lung entsteht, und die amorphe Fällung aus einem geeigneten Lösungsmittel, zum Beispiel Holzgeist, umkristallisiert. Ergo taminmalat ist in Wasser leichter lös lich als die freie Base und reagiert in wässe riger Lösung gegen Lackmus schwach sauer; es bildet mit geeigneten organischen Lösungs mitteln schöne Kristallisationsverbindungen.
Zur Darstellung von Ergotaminmalat in wässerigen Lösungen, sowohl reinen, als auch solchen, denen Konservierungsmittel, wio Alkohol und Glyzerin, zugesetzt sind, fügt man dem Lösungsmittel die ausreichende Menge Äpfelsäure zu und versetzt die so ver dünnte Säure mit einer konzentrierten Lö sung der Ergotaminbase in einem organischen Lösungsmittel, z. B. Alkohol.
Wie die freie Base, so erleiden. auch Ergotaminmalat und seine Lösungen, _ na mentlich am Licht, durch Luftsauerstoff oxydative Veränderungen unter Gelb- und

Process for the preparation of ergotamine malate. The present invention relates to a process for the preparation of the previously unknown salt of the main alkaloid of ergot, ergotamine, with the malic acid, which is common in herbal drugs. The starting material can be the pure base, e.g.
B. their crystallization from hydrous acetone, as mentioned in patent no. 86321, or use an ergotamine-rich alkaloid crude product and in the latter case use the salt formation to separate the ergotamine from accompanying substances ver.
The process for the preparation of er = golamine malate is based on the fact that a sufficient amount of malic acid is allowed to act on ergotamine in the manner of salt formation.
To prepare <B> egg </B> rgotamine malate in solid crystallized form, the free base is expediently dissolved in a water-miscible, indifferent, organic solvent such as alcohol or wood spirit and then the malic acid is added, which causes the crystalline precipitation of Ergo taminmalat is effected.
One can also proceed in such a way that a malic acid solution is carefully added to a solution of the ergotamine in water-immiscible organic solvents, such as ether and benzene, as long as a precipitate is still formed, and the amorphous precipitation from a suitable solvent, for example wood spirit, recrystallized. Ergo tamine malate is more easily soluble in water than the free base and reacts slightly acidic against litmus in an aqueous solution; it forms beautiful crystallization compounds with suitable organic solvents.
To prepare ergotamine malate in aqueous solutions, both pure and those to which preservatives, such as alcohol and glycerine, have been added, a sufficient amount of malic acid is added to the solvent and a concentrated solution of the ergotamine base is added to the diluted acid an organic solvent, e.g. B. Alcohol.
As the free base, so suffer. also ergotamine malate and its solutions, namely in the light, by atmospheric oxygen oxidative changes under yellow and
