Definitions
- the present invention relates to a method for preparing an eucalyptus extract, and more specifically, an essential oil component is removed from a plant belonging to the genus Eucalyptus, and the residue obtained by extracting the residue with water or an organic solvent aqueous solution is further used as an organic solvent aqueous solution. Or it is related with the preparation method of the novel eucalyptus extract which obtains a macrocarpal of high yield by extracting with an organic solvent.
- Eucalyptus plants are high trees native to Australia and New Zealand, and are cultivated in various places in Japan.
- the essential oil (eucalyptus oil) obtained from the leaves has a refreshing sensation and is used for nasal and bronchial catarrh as a medicinal product, as well as for poultices, toothpaste, and insect avoidance.
- this plant is characterized by a very fast growth rate and is suitable for substance production.
- a novel macrocarpal characterized in that an effective physiologically active substance is isolated from an extract of eucalyptus, its partial chemical structure is determined, named as macrocarpal, and collected from a plant of the genus Eucalyptus The manufacturing method is disclosed (patent document 1).
- an extract obtained by extracting a residue obtained by removing essential oil components (eucalyptus oil) from Eucalyptus plants with a polar solvent, and a flow contained therein Logurcinol derivatives have a very strong antibacterial activity against caries and periodontal disease causative bacteria, and also have a collagenase inhibitory effect produced by porphyromonas gingivalis, the causative agent of periodontal disease. has been clarified (Patent Document 2).
- eucalyptus extract has various effects such as ceramide production promoting effect, hair quality improving agent, etc. in addition to antibacterial effect and anti-inflammatory effect, while eucalyptus extract has a unique odor and its odor. Is strong enough that you can feel the odor even if the amount of the extract is small, so when using it for applications such as cosmetics, pharmaceuticals, quasi-drugs, add a sufficient amount in terms of effectiveness Various efforts have been made for problems that could not be achieved.
- Patent Document 3 a method for reducing odor by controlling the ratio of 1,8-cineole and macrocarpal A, which is a causative substance of eucalyptus-specific odor
- Patent Document 4 a method of removing color and odor by adding an adsorbent to an extract solution obtained by extracting Eucalyptus plants with a polar solvent
- an adsorbent was added to the extract obtained by reextracting the residue obtained by extracting the Eucalyptus plant material with water at a low temperature with an alkaline solution and the previous low-temperature water extract in order to increase the yield of the active ingredients of the plant material.
- a method (Patent Document 5) for producing a polyphenol by mixing with a treated liquid is disclosed.
- the present invention provides a method for preparing a eucalyptus extract suitable for use in foods and drinks and capable of obtaining an effective component as a physiologically active substance with high purity and high yield while reducing the peculiar taste (bitterness, astringency) of eucalyptus. To do.

- this is subjected to solid-liquid separation by suction filtration or the like, and the extraction residue obtained by removing the filtrate is further applied with an organic solvent aqueous solution or organic solvent as the second extraction solvent in the second extraction step.
- an organic solvent aqueous solution or organic solvent as the second extraction solvent in the second extraction step.
- the organic solvent similar to the organic solvent aqueous solution used for a 1st extraction solvent can be used.
- the concentration of the organic solvent aqueous solution or organic solvent in this second step is a concentration exceeding 30% by weight, preferably a high concentration of 40 to 100% by weight, and more preferably 50 to 80% by weight. .
- the extraction conditions are the same as those used in the first extraction step, and 2 to 100 times the amount of the organic solvent aqueous solution or organic solvent is added to the first extract residue at 20 to 100 ° C. for 10 minutes. It can be immersed or heated to reflux for -24 hours, preferably heated to reflux.
- the obtained extract is subjected to solid-liquid separation again by suction filtration or the like, the organic solvent is removed, and freeze drying is performed to obtain the target extract.
- the extraction temperature in the two extraction steps is less than 20 ° C.
- the macrocarpals are not sufficiently extracted and the yield is unfavorable.
- the concentration of the first extraction solvent exceeds 30% by weight, impurities other than macrocarpals are mixed, which is not preferable for the purpose of purification.
- the concentration of the second extraction solvent is 30% by weight. If the concentration is low, the yield of macrocarpals decreases, which is not preferable.
- macrocarpals which are physiologically active substances, can be obtained from eucalyptus leaves in high yield.
- macrocarpal A, B and C are effective for anti-cariogenic and periodontal disease effects in addition to anti-viral action and HIV reverse transcriptase inhibitory action.
- macrocarpal A, B and C are approximately 3 to 5 weights compared to conventional extraction methods, such as a single organic solvent extraction method with 60 wt% ethanol extraction. % And more than double the concentration.
- the extract containing the active ingredient with high yield obtained by the preparation method of the present invention can be considered, but chewing gum, candy, tablet confectionery, containing fragrance, taste, and safety are high. It can be used on a daily basis, for example, by blending it into foods such as a plaster and toothpaste, and hygiene products.
- the extract obtained in the present invention is blended in a food or hygiene product, it is preferably added so as to have a ratio of 0.001 to 10% by weight.
- Eucalyptus leaves are demineralized by steam distillation, then dried leaves are crushed, 100 ml of water or 10 to 100% by weight ethanol aqueous solution is added to 10 g of dried leaf powder, and refluxed at 60 to 90 ° C. for about 1 hour. Extracted. The obtained extract was filtered off, the organic solvent was removed from the extract, and then freeze-dried to prepare an extract. The extract was dissolved and quantitative analysis was performed under the following HPLC conditions.
- Table 1 shows the results of a comparison of the content of macrocarpals in Eucalyptus extracts 1 to 9 in which the concentration of the organic solvent aqueous solution was changed when extracting by the preparation method of the comparative example.
- Example 1 Eucalyptus leaves are demineralized by steam distillation, then dried leaves are crushed, and 100 ml of water or 30% by weight ethanol aqueous solution (first extraction solvent) is added to 10 g of dried leaf powder and about 1 at 70 to 90 ° C. Extraction was performed while refluxing for hours. Thereafter, the extract is removed by filtration, and 100 ml of 40 to 100% by weight aqueous ethanol solution or ethanol (second extraction solvent) is further added to the obtained extraction residue and refluxed at 70 to 90 ° C. for about 1 hour. Extracted. The extract was filtered and the organic solvent was removed, followed by lyophilization to prepare an extract. The extract was dissolved and quantitative analysis was performed under the HPLC conditions indicated above.
- Table 2 below shows the comparison results of the contents of macrocarpals in Eucalyptus extracts 10 to 18 in which the concentration of the organic solvent aqueous solution was changed when extracting by the preparation method of Example 1.
- the residue extracted with 0 to 30% by weight of water or an aqueous ethanol solution in the first extraction solvent in Example 1 and the extract prepared with 50 to 80% by weight aqueous ethanol solution in the second extraction solvent were extracted from Eucalyptus. It contains a large amount of macrocarpal in the product, and can suppress the taste (bitterness, astringency) peculiar to eucalyptus, and is optimal in terms of processing characteristics to foods, especially gums, candy, and tablet confectionery, and taste. It was speculated that there was.
- Prescription sugar for tablet candy 76.1% by weight Glucose 19.0 Sucrose fatty acid ester 0.2 Fragrance 0.2 Extract 17 0.5 100% by weight of total remaining water
- the eucalyptus extract can be prepared with a higher content of physiologically active macrocarpals than conventional methods, and the tasting peculiar to eucalyptus is suppressed. It is effective.
