Description

Verfahren zur Gewinnung von therapeutisch wirksamen Stoffen aus Lactuca virosa Es wurde gefunden, daß man die Bitterstoffe der Lactuca virosa in hochkonzentrierter Form dadurch gewinnt, daß man den Preßsaft der Pflanze, den Milchsaft oder eine ähnliche Zubereitung, wie z. B. das nach dem Patent 671 855 hergestellte wasserlösliche Pulver, der Dialyse unterwirft-und das Dialysat im Vakuum konzentriert.Process for the production of therapeutically active substances from Lactuca virosa It has been found that the bitter substances of Lactuca virosa are highly concentrated Form wins by using the pressed sap of the plant, the milky sap or a similar preparation, such as B. the water-soluble prepared according to the patent 671,855 Powder subjected to dialysis - and the dialysate concentrated in vacuo.

Bei der Konzentrierung des Dialysat scheidet sich das Bitterstoffgemisch freiwillig ab und kann durch Filtration gewonnen werden, ohne daß eine langwierige Extraktion mit organischen Lösungsmitteln notwendig ist. When the dialysate is concentrated, the bitter substance mixture separates voluntarily and can be recovered by filtration without the need for a tedious one Extraction with organic solvents is necessary.

Dieses Ergebnis konnte nicht erwartet werden, denn wenn man eine nicht dialysierte wäßrige Lösung eindampft, so findet keine Abscheidung der Bitterstoffe statt. Durch die Dialyse werden die Bitterstoffe überraschenderweise von solchen Stoffen getrennt, welche als Lösungsvermittler wirken. This result could not be expected because when you get one If the non-dialyzed aqueous solution is evaporated, the bitter substances are not deposited instead of. The dialysis surprisingly removes the bitter substances from them Separate substances that act as solubilizers.

Aus dem eingeengten Dialysat wird eine nahezu farblose kristalline Substanz vom Schmelzpunkt I90 bis 1930 erhalten, aus der durch Behandlung mit heißem Methanol oder Wasser vollkommen farblose Kristalle vom Schmelzpunkt 2120 gewonnen werden können; die Kristalle lösen sich leicht in der Wärme in Wasser, Methanol, Alkohol, Azeton und Essigester. The concentrated dialysate becomes an almost colorless crystalline one Substance obtained from melting point 190 to 1930, from which by treatment with hot Methanol or water obtained completely colorless crystals with a melting point of 2120 can be; the crystals dissolve easily in the warmth in water, methanol, Alcohol, acetone and ethyl acetate.

Beispiel I 500 g des Milchsaftes von Lactuca virosa werden je nach Beschaffenheit mit oder ohne Zusatz von Wasser der Dialyse unterworfen. Example I 500 g of the milk juice of Lactuca virosa are used according to Subjected to dialysis with or without the addition of water.

Das Dialysat wird eingeengt, wobei die Bitterstoffe sich abscheiden und auf üblichem Wege gewonnen werden können.The dialysate is concentrated, whereby the bitter substances are deposited and can be obtained in the usual way.

Beispiel 2 Der Preßsaft von Lactuca virosa wird der Dialyse unterworfen.-Die Weiterbehandlung geschieht wie nach Beispiel I. Example 2 The pressed juice of Lactuca virosa is subjected to dialysis Further treatment takes place as in Example I.

Beispiel 3 Zur Dialyse wird eine Lösung verwandt, die durch Auflösung des nach dem Patent 67I 855 gewonnenen trockenen Pulvers in Wasser erhalten wurde. Die weitere Aufarbeitung geschieht ebenfalls, wie in Beispiel I beschrieben, Example 3 A solution is used for dialysis which is obtained by dissolving of the dry powder obtained according to patent 67I855 in water. The further work-up is also carried out as described in Example I,
