Description

[Detailed description of the invention]

The present invention suppresses the formation of dental plaque and prevents caries and periodontal disease by blending organic solvent extracts (crude extracts) of plants selected from arnica, cardamom, zenko, ginseng, and chinensis. The present invention relates to oral compositions. Dental plaque that adheres to the tooth surface is made up of about 70% bacteria, about 20% polysaccharide formed by bacteria, and about 10% food residue, and is firmly stuck to the tooth surface. The acid stored inside demineralizes the enamel, and the bacteria and toxins produced are said to cause gingivitis, periodontitis, and even pyorrhea, two major oral diseases. It is attracting attention as a cause of caries and alveolar pyorrhea. This dental plaque is formed by oral bacteria, mainly Streptococcus miutans, using sucrose present in the oral cavity. That is, Streptococcus miutans produces GTF (glucosyltransferase, dextran synthase), which synthesizes sticky polysaccharides such as dextran and mutan from sucrose. This synthesized polysaccharide then attracts Streptococcus miutans and other bacteria (pathogens), forming dental plaque with a certain bacterial flora. Furthermore, bacteria such as Streptococcus miutans produce acids using various sugars, and this acid demineralizes the enamel surface by staying in the walls of polysaccharides and bacteria. Furthermore, dead bacteria and various substances produced,
Toxins have a negative effect on the gums and act as a cause of pyorrhea. Therefore, suppressing and preventing the formation of dental plaque is
This is extremely effective in preventing caries and periodontal disease. Taking these points into consideration, the present inventors have investigated caries, caries,
We conducted extensive research into oral compositions suitable for the prevention of periodontal diseases and screened various plants as natural additives. As a result, we found that organic solvent extracts of arnica, cardamom, zenko, ginseng, and Japanese cutlet were found to be effective as streptococcal ingredients. It has been found that the organic solvent extract suppresses the formation of dental plaque caused by C. myutans, and is therefore suitable as an active ingredient of an oral composition for preventing dental caries and periodontal disease.
The present invention has been accomplished. The present invention will be explained in detail below. The oral composition according to the present invention includes toothpaste, toothpaste,
It is used as toothpaste such as water toothpaste, mouthwash, pastilles, pasta, liniment, chewing gum, gargling tablets, etc.The active ingredients are organic solvent extracts of arnica, cardamom, zenko, ginseng, and chinensis. 1 or 2 of
It is made by blending more than one species. As the organic solvent used for extracting the plants, lower alcohols such as methanol and ethanol, polar solvents such as acetone, ethyl ether, and ethyl acetate, and nonpolar solvents such as benzene, hexane, and petroleum ether can be used. Mixed solvents such as aqueous ethanol may also be used. The organic solvent extract used as an active ingredient in the present invention is obtained by extracting the above-mentioned plants with one type or a mixture of two or more of these organic solvents, or a mixture of these organic solvents and water, and removing the extraction residue. can be produced by distilling off the solvent from the extract, if necessary. Note that a known method can be used as the extraction method, for example, a method such as digesting the dried powder of the plant in an organic solvent can be used. The amount of the organic solvent extract incorporated into the oral composition is 0.001 to 5% (wt%, same hereinafter) of the total,
In particular, it is preferably 0.005 to 2%. As other components of the present invention, appropriate components are used depending on the type of oral composition. For example, in the case of toothpaste, dibasic calcium phosphate, calcium carbonate, calcium pyrophosphate, insoluble sodium metaphosphate, amorphous silica, crystalline silica, aluminosilicate, aluminum oxide, aluminum hydroxide, abrasives such as resin, carboxylic Methylcellulose, hydroxyethylcellulose, alginate, carrageenan, gum arabic,

Foaming agents such as sodium N-lauroyl sarcosinate, N-acylglutamate, and sucrose fatty acid esters, essential oils such as peppermint and spearmint, fragrance materials such as l-menthol, carvone, eugenol, and anethole, and saccharin. It is produced by mixing ingredients such as sodium, stevioside, neohesperidyl dihydrochalcone, glycyrrhizin, perillartin, sweeteners such as p-methoxycinnamic aldehyde, preservatives, etc. with water and according to a conventional method. Furthermore, in mouthwashes and other mouthwashes, ingredients are appropriately blended depending on the properties of the product. In the present invention, in addition to the above-mentioned organic solvent extract of plants, lysozyme chloride, dextranase, lytic enzyme, mutanase, chlorhexidine, sorbic acid, alexidine, hinokitiol, cetylpyridinium chloride, alkylglycine, alkyldiaminoethylglycine are used. Salt, allantoin, ε-aminocaproic acid, tranexamic acid, azulene, vitamin E, sodium monofluorophosphate, sodium fluoride, fluoride 1
Active ingredients such as tin, water-soluble primary or secondary phosphates, quaternary ammonium compounds, sodium chloride, etc. can also be incorporated. The oral composition according to the present invention contains one or more organic solvent extracts of plants selected from arnica, cardamom, zenko, ginseng, and sagebrush. It effectively suppresses the formation of plaque, thus effectively preventing the occurrence of dental caries and periodontal disease. Next, experimental examples will be shown to specifically explain the effects of the present invention. [Experiment example] 100g of dry cardamom powder and 300ml of methanol
was added and refluxed for 1 hour on a 70-80°C water bath with a condenser attached. Next, the methanol fraction was separated, fresh methanol was added to the residue, and the same reflux was repeated twice, for a total of three extraction operations. The methanol extracts were collectively concentrated under reduced pressure to obtain 9.0 g of a brown paste. The other plants shown in Table 1 were operated in the same manner as above to obtain methanol extracts of each plant. Next, the above extract was used as a test sample, and its degree of inhibition of plaque formation was evaluated by the culture attachment method described below. Culture attachment method: Place the above test sample on BHI medium containing 1% sucrose.
Streptococcus miutans strain 6715, which had been pre-cultured with 0.1%, was inoculated.
The cells were cultured at 37° C. for 16 hours in an Anaerobox gas exchanged with N ₂ :CO ₂ :H ₂ =80:10:10. After culturing, gently wash twice with 0.01M phosphate buffer (PH7.0), then add the same amount of the same buffer as the culture solution, stir vigorously, and perform ultrasonication for about 20 seconds. After the dental plaque was homogeneously suspended, the absorbance (turbidity) was measured at 550 nm using a photometer to determine the amount of attached dental plaque. The results are shown in Table 1. The results are expressed as a percentage, with the amount of plaque attached to the control to which no test sample was added as 100%.

[Table] From the above results, it was found that the methanol extracts of each plant shown in Table 1 effectively suppress the formation of dental plaque. Examples are shown below. Note that all % indicates weight %. Furthermore, in the following examples, methanol crude extracts of plants were used.
