Description

Extrakt extract
Die vorliegende Erfindung betrifft einen Extrakt.The present invention relates to an extract.
Als Mate wird der heiße Aufguss (Tee) aus den zerkleinerten Blättern und Blattstielen der südamerikanischen Stechpalme Hex paraquensis St. Hil bezeichnet. Der Baum wird auch als Yerba-Mate-Baum bezeichnet. Für diesen Tee wird üblicherweise mehrfach heißes Wasser über die bereits extrahierten Teeblätter gegeben. Es gelingt jedoch nicht, die Inhaltsstoffe des Tees vollständig zu extrahieren. Die Herstellung entsprechender Extrakte ist beschrieben in F. von Bruchhausen u.a. (Herausgeber) : Hagers Handbuch der Pharmazeutischen Praxis, 5. Auflage, Band 5, Seiten 508 bis 511, auf das ausdrücklich Bezug genommen wird.Mate is the hot infusion (tea) made from the shredded leaves and petioles of the South American holly Hex paraquensis St. Hil. The tree is also known as the yerba mate tree. For this tea, hot water is usually poured several times over the tea leaves already extracted. However, it is not possible to completely extract the ingredients of the tea. The preparation of such extracts is described in F. von Bruchhausen et al. (Editor): Hager's Handbook of Pharmaceutical Practice, 5th Edition, Volume 5, pages 508 to 511, to which express reference is made.
Die Blätter des Süßkrautes schmecken ausgesprochen süß, Extrakte aus den Blättern sind in einigen Ländern als Süßungsmittel zugelassen. Die Süßkraft ist etwa 300mal größer als die von Saccharose. Die entsprechenden Extrakte sind beschrieben in F. von Bruchhausen u.a. (Herausgeber): Hagers Handbuch der Pharmazeutischen Praxis, Band 6, auf das hier ausdrücklich Bezug genommen wird.The leaves of the sweet herb taste extremely sweet, extracts from the leaves are approved as sweeteners in some countries. The sweetness is about 300 times greater than that of sucrose. The corresponding extracts are described in F. von Bruchhausen et al. (Editor): Hager's Handbook of Pharmaceutical Practice, Volume 6, to which express reference is made here.
Extrakte der Sojabohnen sind beschrieben in F. von Bruchhausen, Hagers Handbuch der Pharmazeutischen Praxis, Band 5, Seiten 307 bis 311, auf das ausdrücklich Bezug genommen wird. Überraschenderweise wurde nun gefunden, dass sich durch Kombination der bekannten Extrakte ein Extrakt erhalten lässt, aus dem sich ein Getränk zubereiten lässt, das einen angenehmen Geschmack aufweist, gesundheitsfördernd wirkt und gut verträglich ist. Darüber hinaus ist die Kombination ausgewogen, nährstoffreich und auch für Diabetiker geeignet.Extracts of soybeans are described in F. von Bruchhausen, Hager's Handbook of Pharmaceutical Practice, Volume 5, pages 307 to 311, to which express reference is made. Surprisingly, it has now been found that by combining the known extracts, an extract can be obtained from which a drink can be prepared which has a pleasant taste, has a health-promoting effect and is well tolerated. In addition, the combination is balanced, nutrient-rich and also suitable for diabetics.
Das Extrakt kann auch für kosmetische und Körperpflegeprodukte eingesetzt werden.The extract can also be used for cosmetic and personal care products.
Das erfindungsgemäße Extrakt enthältThe extract according to the invention contains
a) Extrakt gewonnen durch Extraktion von Blättern des Yerba-Mate- Baums (Hex paraquensis St. Hil.), die getrocknet und zerkleinert wurden; b) Extrakt gewonnen durch Extraktion von Blättern des Süßkrautes (Stevia rebaudiana), die getrocknet und zerkleinert wurden, c) Extrakt gewonnen durch Extraktion von kaffeebraun gerösteten, gemahlenen Sojabohnen (Früchte der Soja hispida).a) extract obtained by extracting leaves of the yerba mate tree (Hex paraquensis St. Hil.), which have been dried and crushed; b) extract obtained by extracting leaves of the sweet herb (Stevia rebaudiana), which have been dried and crushed, c) extract obtained by extracting coffee-roasted, ground soybeans (fruits of the soybean hispida).
Die Extrakte können jeweils in gleichen oder verschiedenen Anteilen im erfindungsgemäßen Kräuterextrakt enthalten sein. Bevorzugt sind Anteile jeweils zwischen 0,01 und 99%, noch mehr bevorzugt zwischen 10 und 90%.The extracts can each be present in the same or different proportions in the herbal extract according to the invention. The proportions are preferably between 0.01 and 99%, more preferably between 10 and 90%.
Die Extraktion erfolgt bevorzugterweise durch Wasser mit einem Gehalt von 0% bis 60%, bevorzugt 10% bis 30% (v/v) Ethanol. Um die Extraktion möglicherweise unerwünschter Begleitstoffe, die überwiegend in Ethanol löslich sind, so gering wie möglich zu halten, wird eine möglichst geringe Ethanol-Konzentration im wässrigen Extraktionsmittel verwendet. So sind z.B. ca. 5% Ethanol geeignet, um die Extraktion z.B. von Saponi- nen in störendem Umfang zu vermeiden. Soll das Extrakt in Shampoos oder ähnlichem eingesetzt werden, kann auch mit höherer Ethanol- Konzentration gearbeitet werden, da dabei eine eventuelle Schaumbildung durch das Saponin nicht negativ in Erscheinung tritt. Für die Qualität des Extraktionsmaterials hat sich als vorteilhaft erwiesen, wenn die Blätter des Yerba-Mate-Baums vor der Extraktion für ein, bevorzugt für zwei Jahre im getrockneten Zustand gelagert werden. Die Qualität kann weiter dadurch verbessert werden, daß die Blätter vor der Trocknung kurz flambiert und für 1 bis 10 Stunden gegoren werden. Das so erhaltene Kräuterextrakt eignet sich insbesondere zur Herstellung eines Getränks.The extraction is preferably carried out by water with a content of 0% to 60%, preferably 10% to 30% (v / v) ethanol. In order to keep the extraction of possibly undesired accompanying substances, which are predominantly soluble in ethanol, as low as possible, the lowest possible ethanol concentration in the aqueous extractant is used. For example, about 5% ethanol is suitable to avoid the extraction of saponins, for example, to a disruptive extent. If the extract is to be used in shampoos or the like, it is also possible to work with a higher ethanol concentration, since any foam formation caused by the saponin does not have a negative effect. It has proven to be advantageous for the quality of the extraction material if the leaves of the yerba mate tree are stored in the dried state for one, preferably for two years before the extraction. The quality can be further improved by flaming the leaves briefly before drying and fermenting for 1 to 10 hours. The herbal extract obtained in this way is particularly suitable for producing a drink.
Das Verfahren zur Extraktion von Blättern des Yerba-Mate-Baums, Blättern des Süßkrauts oder von gerösteten und gemahlenen Sojabohnen beruht auf einer Extraktion mit Wasser enthaltend 0% bis 60%, bevorzugt bis zu 50% (v/v), noch mehr bevorzugt bis zu 30% (v/v) Ethanol.The method for extracting leaves of the yerba mate tree, leaves of sweet herb or of roasted and ground soybeans is based on an extraction with water containing 0% to 60%, preferably up to 50% (v / v), more preferably up to to 30% (v / v) ethanol.
Vorzugsweise umfasst das Verfahren folgende Schritte:The method preferably comprises the following steps:
l. Die Extraktion aus den bezeichneten Pflanzenteilen erfolgt aus zerkleinertem Pflanzenmaterial mit Hilfe eines 50%igen (v/v) Ethanol- Wasser-Lösung.l. The extraction from the designated parts of the plant takes place from shredded plant material with the help of a 50% (v / v) ethanol-water solution.
2. Die Menge Lösungsmittel muss ausreichend sein um das gesamte Pflanzenmaterial zu bedecken.2. The amount of solvent must be sufficient to cover the entire plant material.
3. Das Extraktionsgemisch wird für 10 bis 14 Tage bei Raumtemperatur mazeriert.3. The extraction mixture is macerated for 10 to 14 days at room temperature.
4. Nach der Mazerationszeit wird der Extrakt abgezogen und zur Vorklärung 24 Stunden bei Raumtemperatur gelagert und anschließend bis zur vollständigen Klärung filtriert.4. After the maceration time, the extract is drawn off and stored for 24 hours at room temperature for preliminary clarification and then filtered until it is completely clear.
5. Aus den bisher gewonnenen Einzelextrakten können Mischung alkohol- artiger Anwendungen, in unterschiedlichen Anteilen der Einzelextrakte, hergestellt werden.5. Mixtures of alcohol- like applications, in different proportions of the individual extracts.
6. Zur Herstellung alkoholfreier Anwendungen wird dem Alkohol-Wasser- Extrakt in gleichem Volumenanteil Propylenglykol zugesetzt wie Volumenanteil an reinen Alkohol in dem Extrakt vorhanden ist und der Alkohol durch Destillation entfernt.6. In order to produce non-alcoholic applications, propylene glycol is added to the alcohol-water extract in the same volume fraction as the volume fraction of pure alcohol is present in the extract and the alcohol is removed by distillation.
7. Die nun alkoholfreie Anwendung wird zur Konzentratioπseinstellung mit Propylenglykol bis zum gewünschten Volumen aufgefüllt. Die alkoholfreie Anwendung wird anschließend bis zur vollständigen Klärung filtriert.7. The now alcohol-free application is filled with propylene glycol to the desired volume to adjust the concentration. The alcohol-free application is then filtered until it is completely clear.
Durch das erfindungsgemäße Verfahren können bis zu 30% der ursprünglichen Menge der zu extrahierenden Substanzen in den Extrakt überführt werden. Als Extraktion eignet sich eine Extraktion mit dem Extraktionsmittel bei Raumtemperatur über einen Zeitraum von 10 bis 14 Tagen aber auch eine Soxhiett-Extraktion, da insbesondere hierdurch eine hohe Auslaugung des Extraktionsmaterials bei geringem Lösemittelbedarf erreicht werden kann. Beispielsweise können 25 g des zu extrahierenden Materials 8 Stunden lang mit 100 ml einer Wasser-Ethanol- Mischung extrahiert werden, wobei nach Eindampfen des Extraktes je nach Gehalt an Ethanol 20 Gew.-% bis 32 Gew.-% Mate-Extrakt, 24 Gew.-% bis 35 Gew.-% Süßkraut-Extrakt bzw. 10 Gew.-% bis 20 Gew.- % Sojabohnen-Extrakt erhalten werden. Es kann insbesondere ratsam sein, nach der Extraktion noch eine Filtration durchzuführen, um unlösliche Substanzen aus dem Extrakt zu entfernen.Using the method according to the invention, up to 30% of the original amount of the substances to be extracted can be converted into the extract. An extraction with the extractant at room temperature over a period of 10 to 14 days is also suitable as a Soxhiett extraction, since this in particular enables a high leaching of the extraction material with a low solvent requirement. For example, 25 g of the material to be extracted can be extracted for 8 hours with 100 ml of a water-ethanol mixture. After evaporation of the extract, depending on the ethanol content, 20% by weight to 32% by weight of mate extract, 24% by weight .-% to 35 wt .-% sweet herb extract or 10 wt .-% to 20 wt .-% soybean extract can be obtained. It may be particularly advisable to carry out a filtration after the extraction in order to remove insoluble substances from the extract.
Durch das erfindungsgemäße Verfahren kann die Extraktion von Inhaltsstoffen aus Blättern des Yerba-Mate-Baums, Blättern des Süßkrauts und von kaffeebraun gerösteten, gemahlenen Sojabohnen standardisiert wer- den. Diese können in besonders einfacher Weise von den Herstellungsorten an die Verwendungsorte transportiert werden, wo sie zur Herstellung eines Getränks verwendet werden können. Entsprechende Extrakte sind leichter zu transportieren und haltbarer als trockene Blätter.The method according to the invention can be used to standardize the extraction of ingredients from leaves of the yerba mate tree, leaves of sweet herb and from coffee-roasted, ground soybeans. the. These can be transported in a particularly simple manner from the places of manufacture to the places of use, where they can be used to produce a drink. Appropriate extracts are easier to transport and more durable than dry leaves.
