Patentiert im Deutschen Reiche vom 16. November 1912 ab.Patented in the German Empire on November 16, 1912.
Es hat sich gezeigt, daß Trehalose sehr vorteilhaft zu medizinischen und kosmetischen Zwecken sowie als Konservierungsmittel Anwendung finden kann. Dies ließ sich aber bisher nicht verwerten, denn Trehalose ist kein Handelsprodukt, da es nur in geringer Menge erhalten werden kann und deshalb viel zu kostspielig ist.It has been shown that trehalose is very beneficial to medicinal and cosmetic Purposes and as a preservative can be used. But this was possible so far not utilize, because trehalose is not a commercial product, as it is only low Amount can be obtained and is therefore far too costly.
So entstand die Aufgabe, ein zur HerstellungSo the task arose to manufacture one
ίο im großen ausführbares Verfahren zu finden, welches die Nutzbarmachung des genannten Körpers in der Medizin, Kosmetik und als Konservierungsmittel ermöglicht.ίο to be found in the large executable procedure, which the utilization of said body in medicine, cosmetics and as Preservatives made possible.
Im nachstehenden ist das Verfahren beschrieben, welches dem genannten Ubelstand abhilft.In the following the procedure is described, which the mentioned Ubelstand remedies.
Als Ausgangsmaterial dienen die Selaginellaceen. The Selaginellaceae serve as the starting material.
Aus den Arten der Selaginellaceen wird so durch Extraktion mit einem geeigneten Lösungsmittel, z. B. Spiritus oder Wasser, ein Extrakt erhalten, welcher frei von Chlorophyll und Harzen ist. Dieser Extrakt ist sehr reich an Trehalose.The species of Selaginellaceae are extracted with a suitable solvent, z. B. alcohol or water, an extract is obtained which is free of chlorophyll and resins. This extract is very rich in trehalose.
Man kann aus dem Extrakt durch Abscheidung mittels Lösungsmittel, in denen Trehalose schwer löslich ist, z. B. Spiritus, Trehalose kristallisiert erhalten.One can from the extract by separation using solvents in which Trehalose is sparingly soluble, e.g. B. alcohol, trehalose get crystallized.
Es hat sich ferner gezeigt, daß in dem genannten Extrakt unter anderem in geringerer Menge eine neue Säure, Selaginellsäure, sich befindet, die schon in geringsten Mengen dadurch nachweisbar ist, daß sie mit Alkalien goldgelb gefärbte Lösungen gibt.It has also been shown that in the extract mentioned, inter alia, in less Amount of a new acid, selaginellic acid, is already present in the smallest amounts it can be shown that it gives golden yellow colored solutions with alkalis.
Diese Säure kann aus dem Extrakt als schwer lösliches Salz, ζ. Β. Bleisalz, abgeschieden oder durch mit Wasser nicht mischbare Lösungsmittel extrahiert werden. Sie ist zu medizinischen und kosmetischen Zwecken geeignet.This acid can be found in the extract as a poorly soluble salt, ζ. Β. Lead salt, deposited or extracted by water immiscible solvents. It is for medical and cosmetic use suitable.

Ausführungsbeispiel:Embodiment:
20 kg Selaginellaceenpulver, beispielsweise von Selaginella lepidophylla Spring, Selaginella cuspidata Link, werden mit 150 1 Wasser in der Hitze .extrahiert, koliert und das Filtrat noch heiß mit 3 kg Bleiessig (oder 10 proz. Bleiacetatlösung usw.) versetzt. Der Niederschlag wird filtriert und nach dem Auswaschen in Wasser suspendiert und das Blei mit Schwefelwasserstoff gefällt. Das Filtrat vom Schwefelblei wird eingeengt und mit Calciumcarbonat das Kalksalz der Selaginellsäure gefällt. Es werden auf diese Weise etwa 80 bis 100 g Kalksalz gewonnen, aus dem nach weiterer Reinigung die freie Säure dargestellt wird. Nach Abscheidung des Kalksalzes der Selaginellsäure wird das Filtrat eingedampft, der Rückstand mit heißem Alkohol ausgezogen und die Trehalose zur Kristallisation gebracht. Die Ausbeute an Trehalose beträgt etwa 2,5 Prozent. Trehalose Wird auch auf folgendem Wege direkt durch Akohol in guter Ausbeute gewonnen. Das20 kg Selaginellaceae powder, for example from Selaginella lepidophylla Spring, Selaginella cuspidata Link, are extracted with 150 l of water in the heat, and the filtrate 3 kg of lead acetic acid (or 10 percent lead acetate solution, etc.) are added while it is still hot. The precipitation is filtered and, after washing, suspended in water and the lead is precipitated with hydrogen sulfide. The filtrate the lead sulfur is concentrated and the calcium carbonate is added to the lime salt of selaginellic acid pleases. In this way, about 80 to 100 g of lime salt are obtained from which after further purification the free acid is represented. After separation of the lime salt the selaginellic acid, the filtrate is evaporated, the residue with hot alcohol pulled out and brought the trehalose to crystallization. The yield of trehalose is about 2.5 percent. Trehalose Is also obtained in the following way directly from alcohol in good yield. That
