Definitions
- the invention relates to an extraction method in which an extraction agent is used to release at least one extraction material from a substance, in particular a plant material.
- the invention also relates to a substance mixture that contains an extraction material extracted from a substance, in particular a plant material.
- the invention is based on the object of creating a method of the type mentioned at the outset that enables extraction that is more efficient than the known methods.
- the extractant contains fatty acid ethyl ester and/or fatty acid methyl ester.
- the extraction material can be separated particularly well from the substance when using fatty acid ethyl ester and/or fatty acid methyl ester.
- the method for extracting cannabinoids, in particular phytocannabinoids has proven to be particularly advantageous.
- the extraction is preferably carried out from hemp. Not only is a comparatively large extraction yield achieved, but the process can also be carried out efficiently in a comparatively large temperature range.
- the invention has proven to be particularly advantageous for the extraction of medicinal hemp, for example the Cannabis sativa L.
- Cannabis sativa L. 'Ludina' variety the Cannabis sativa L. 'Elida' variety, the Cannabis sativa L. 'Talea' and/or the variety Cannabis sativa L. 'Rensina'.
- the method can also be used advantageously for the extraction of extraction material from other plants or components thereof, e.g.
- tea plants e.g. Camellia sinensis, Camellia assamica
- the method is also suitable for producing the mixture of substances mentioned at the outset, which has fatty acid ethyl ester and/or fatty acid methyl ester and contains an extraction material extracted from a substance, in particular a plant material. It is conceivable to aromatize fatty acid ethyl esters and/or fatty acid methyl esters by means of the process. Furthermore, fatty acid ethyl ester and/or fatty acid methyl ester can be enriched with the extraction material by means of the method.
- the fatty acid ethyl ester contained in the substance mixture and/or the fatty acid methyl ester forms the extractant.
- the mixture of substances is treated after the extraction, if necessary for purification, preferably by means of filtration, particularly preferably by means of an activated carbon filter. Chlorophyll, for example, can be removed from the mixture of substances by means of such a treatment.
- the fatty acid ethyl ester and/or fatty acid methyl ester is expediently of pharmaceutical quality.
- it has been manufactured under the conditions of the rules for "Good Manufacturing Practice for Drugs” (GMP; "Good Manufacturing Practice"), preferably in accordance with the Drug and Active Ingredient Manufacturers Ordinance (AMWHV). It preferably corresponds to the purity specified in the United States Pharmacopeia-National Formulary, British Pharmacopeia or European Pharmacopoeia.
- the fatty acid ethyl ester comprises or is an omega-3 and/or omega-6 fatty acid.
- An omega-3 and/or omega-6 fatty acid which is enriched with the extraction material can advantageously be formed by means of the method.
- Omega-3 and/or omega-6 fatty acids are known to have particularly health-promoting effects as food and dietary supplements.
- the invention proves to be particularly advantageous if, after the extraction, the extraction material is present, in particular dissolved, in the extraction agent, in particular the omega-3 and/or omega-6 fatty acid.
- a fatty acid ethyl ester and/or fatty acid methyl ester enriched with the extraction material can then be produced directly with the method.
- combination preparations can be produced directly and therefore comparatively easily. It is therefore not necessary to first detach the extraction material from the substance, in particular the plant, by means of another method, and then to add the fatty acid ethyl ester, in particular the omega-3 and/or omega-6 fatty acid, to the extraction material.
- the invention has proven to be particularly advantageous if the extraction agent has or is EPA, DHA, DPA, ETA, 21:5n3 or/and SDA.
- omega-3 fatty acids especially EPA and DHA, are particularly healthy foods or dietary supplements.
- Fatty acid methyl ester is used in many applications as a vegetable fuel.
- the invention creates the possibility of enriching fatty acid methyl esters with the extraction material in a particularly simple manner.
- the advantages of using the fatty acid methyl ester as an extraction agent are that it can be sustainably produced from vegetable fats and is inexpensive and readily available. Furthermore, the extractant can be used particularly economically for short-path distillation.
- the use of the fatty acid methyl ester in the extraction from hemp has proven to be particularly advantageous.
- Cannabinoids, especially phytocannabinoids, and terpenes also present in hemp can be separated by short-path distillation using fatty acid methyl esters. In particular, the separation can take place via different boiling points.
- the extractant is a mixture of substances, preferably an oil.
- the organic solvent is expediently an alcohol, preferably ethanol, methanol, n-butanol and/or isopropanol.
- the extractant has at least 90 mg/g, preferably at least 120 mg/g, of fatty acid ethyl ester, preferably EPA and/or DHA, and/or at least 175 mg/g, preferably at least 190 mg/g, of fatty acid methyl ester.
- an extractant which contains at least 500 mg/g, preferably at least 700 mg/g, particularly preferably at least 900 mg/g, of fatty acid ethyl ester, preferably EPA and/or DHA; and/or at least 500 mg/g, preferably at least 700 mg/g, particularly preferably at least 900 mg/g fatty acid methyl ester.
- a product intended for consumption in particular a food supplement to which the extraction material has been added, can optionally be formed directly using the fatty acid ethyl ester as the extraction agent.
- the extraction process is carried out in such a way that the mixture of substances contains the extraction material, in particular the cannabinoid, possibly the phytocannabinoid, preferably the CBD, the THC and/or the CBD-A, in a content of at least 5% by weight. -%, preferably at least 25% by weight, particularly preferably 50% by weight.
- the mixture of substances is suitable as a food or supplement.
- larger contents in particular with a content of at least 25% by weight, preferably at least 50% by weight, the mixture of substances is suitable for medical use or as a medical product.
- the component to be released is a cannabinoid, in particular a phytocannabinoid, preferably CBD and/or THC, and/or a terpene.
- the substance from which the extraction material is extracted is preferably hemp, particularly preferably medicinal hemp, in particular the variety Cannabis sativa L. 'Afina', the variety Cannabis sativa L. 'Ludina', the variety Cannabis sativa L. 'Elida', the Cannabis sativa L. 'Talea' variety and/or Cannabis sativa L. 'Rensina' variety.
- Omega-3 and/or omega-6 fatty acids are partially metabolized to epoxides in the human body. These epoxides can be converted to omega-3 and/or omega-6 fatty acid endocannabinoid epoxides by cytochrome P450. These endogenous endocannabinoid epoxides have proven to be particularly bioactive. They have an anti-inflammatory, vasodilatory (vasodilating) effect and can modulate platelet aggregation. In addition, omega-3 and/or omega-6 fatty acids have been shown to be beneficial for the effectiveness of cannabinoids, especially phytocannabinoids.
- Omega-3 and/or omega-6 fatty acids act as anchors for the endocannabinoids and for cannabinoids, especially phytocannabinoids, in the cell membrane. They are involved in the synthesis of receptors of the endocannabinoid system, which forms part of the human or animal nervous system.
- cannabinoids, in particular phytocannabinoids, with omega-3 and/or omega-6 fatty acids can thus contribute to improving the effects caused by both substances.
- omega-3 and/or omega-6 fatty acids which are enriched with cannabinoids, in particular phytocannabinoids, is considered to be particularly advantageous for use in pain therapy and/or chemotherapy, since they have a synergetic effect when administered together show effect. While the omega-3 and/or omega-6 fatty acids in particular have an anti-inflammatory effect and this alone enables a reduction in painkillers, the cannabinoids can block the descending nerve tracts in particular and thus allow a reduction in the necessary dose of painkillers.
- omega-3 and/or omega-6 fatty acid and cannabinoids, in particular phytocannabinoids, according to the invention is particularly advantageous when used concomitantly with pain therapy with another painkiller, in particular an opioid, because the additional intake of the omega -3 and/or omega-6 fatty acid mixed with the cannabinoid, in particular phytocannabinoid, allows a particularly large reduction in the necessary dose of the other analgesic, in particular the opioid.
- the substance is expediently incubated before extraction.
- the incubation is preferably between 80°C and 120°C, preferably between 90°C and 110°C.
- the mixture of substances mentioned at the outset which contains an extraction material extracted from a substance, in particular a plant material, has fatty acid ethyl esters and/or fatty acid methyl esters.
- the fatty acid ethyl ester and/or fatty acid methyl ester of the substance mixture is an extractant by means of which the extraction material has been extracted, the extraction material preferably being dissolved in the fatty acid ethyl ester and/or fatty acid methyl ester.
- the mixture of substances expediently contains the extraction material, in particular the cannabinoid, in particular the phytocannabinoid, preferably the CBD, the THC and/or the CBD-A, in a content of at least 3% by weight, preferably at least 6% by weight, in particular preferably at least 9% by weight.
- the substance mixture has substance components of the extraction material, in particular substance components of the cannabinoid, in particular phytocannabinoid, preferably CBD, THC and/or CBD-A, and/or the terpene in a ratio of the substance components to one another which corresponds to the substance component ratio of the extraction material, in particular the cannabinoid and/or terpene substance component ratio in which the plant material corresponds or at least essentially corresponds.
- substance components of the extraction material in particular substance components of the cannabinoid, in particular phytocannabinoid, preferably CBD, THC and/or CBD-A, and/or the terpene in a ratio of the substance components to one another which corresponds to the substance component ratio of the extraction material, in particular the cannabinoid and/or terpene substance component ratio in which the plant material corresponds or at least essentially corresponds.
- FIGS. 1 to 3 show substance contents after various processes or process steps have been carried out.
- Finola hemp was incubated for two hours at 100 °C to decarboxylate CBD-A to CBD and THC-A to THC.
- Finola hemp was incubated for two hours at 100 °C to decarboxylate CBD-A to CBD and THC-A to THC.
- the weight (total g) of cannabinoids in the extraction product formed was determined and their concentration in the extraction product formed was measured.
- the extraction product was used again as an extraction agent in a second extraction step.
- 5 g of the extraction product of cannaboid-enriched omega-3 fatty acid oil obtained after the first extraction was again added to 10 g of the incubated hemp and left to stand at 23° C. for 1 h. It was then filtered again and that formed filtrate and the filter washed with 30 g ethanol to dissolve the omega-3 fatty acid oil from the filter and the filter cake.
- the weight (total g) of cannabinoids in the extraction product formed was determined and their concentration in the extraction product formed was measured.
- the extraction product formed after the second extraction step was reused as an extractant in a third extraction step.
- 5 g of the cannaboid-enriched omega-3 fatty acid oil extraction product obtained after the second extraction was again added to 10 g of the incubated hemp and allowed to stand at 23°C for 1 h. It was then filtered again and the filtrate formed and the filter washed with 30 g ethanol in order to dissolve the omega-3 fatty acid oil from the filter and the filter cake.
- the weight (total g) of cannabinoids in the extraction product formed was determined and their concentration in the extraction product formed was measured.
- Finola hemp was incubated for two hours at 100 °C to decarboxylate CBD-A to CBD and THC-A to THC.
- Results of this measurement are that the highest yield was obtained at the highest temperature and longest incubation. Values identical to those at 30 °C were obtained at the highest temperature and the lowest incubation time. The lowest temperature is not suitable for extraction due to low yield. By doubling the temperature and quadrupling the incubation time, only a 17% increase was achieved compared to 30°C and 30 min incubation.
