Description

Composition for oral care {COMPOSITION FOR ORAL CARE}

The present invention relates to a composition for oral care, including herbal ingredients, in particular mugwort, licorice, yellow lotus, yeonkyo, and relates to a composition with significantly improved anti-inflammatory and antibacterial efficacy.

Toothpastes generally include abrasives, foaming agents, wetting agents, binders, flavoring agents, and the like, and further include fluorine compounds to reinforce tooth structure and improve acid resistance, thereby increasing tooth resistance to caries. Periodontal disease occurs in more than half of adults over 20 years of age, 3 in 4 people after 35 years of age, and 80-90% of older adults over 40 years of age. This periodontal disease is caused by entanglement of non-aqueous glucan, microorganisms and food residues produced by oral disease-causing bacteria including Staphylococcus aureus among 200 kinds of microorganisms living in the oral cavity. It forms a periodontal bacterial membrane, which is a periodontal disease when toxic bacteria or toxins produced by the plaque invade the periodontal tissue, causing inflammation of the gingiva, destruction of alveolar bone, and infection, and these bacteria produce acid. This can cause dental caries.

Recently, in order to prevent and treat periodontal diseases including such dental caries, various antibacterial or anti-inflammatory agents for oral bacteria have been developed. Examples of antibacterial agents include bisbiguanides preparations, quaternary ammonium preparations and phenolic compounds. However, these antimicrobial agents are chemically synthesized, and many side effects have been reported.

Therefore, in recent years, research on natural product formulations with fewer side effects has been increasing, but toothpaste compositions for oral care having anti-inflammatory and antimicrobial effects that are satisfactory for the user have not been developed.

Therefore, in order to prevent or treat such periodontal disease, dental caries, and the like, development of a composition for oral care containing natural materials having anti-inflammatory and antibacterial functions is required.

Example 1 Preparation of Extract

Please list extraction method as follows.

Artemisia princeps Pam.Var.orientlis Hara, Glycyrrhiza uralensis Fischer , Coptis japonica Makino and Forsythia suspensa Vahl used in this experiment were purchased from pharmacists, washed with water, dried and dried 100 g was taken in 50% ethanol and reflux cooled for 72 hours. Thereafter, the filtrate was concentrated and freeze-dried to obtain a mugwort extract (yield 18.6%), licorice extract (yield 21.2%), rhubarb extract (yield 19.8%), pontoon extract (yield 17.6%), and dissolved in distilled water, 0.2 um filter (Millipore). Corporation, Bedford, MA, USA) was used as a sample of the following experimental example.

Reference Example 1. Experimental strain and culture

(1) As cell lines for anti-inflammatory test, DMEM (Dulbecco's modified Eagle's medium) added 50 µg / ml of fetal bovine serum (FBS) and gentamicin (5% inactivated) using mouse macrophages RAW264.7 ) In culture at 37 ° C., 5% CO ₂ incubator.

(2) As a strain for the antibacterial test, Staphylococcus aureus (KCTC 1621, Korea Research Institute of Biotechnology and Microbial Resources Center) was added to a nutrient medium (0.3% Beef extract, 0.5% peptone, pH 6.8, Becton, Dickinson). and Company, USA.) Strain stocks were inoculated into nutrient media, then activated by preculture at 37 ° C. for 24 hours, and then the strains were recovered, washed three times with sterile water and prepared.

Experimental Example 1. Determination of the anti-inflammatory effect of a mixture of mugwort extract, licorice extract, rhubarb extract, yeonja extract and mugwort / licorice / rye / yeonja extract

(1) Determination of nitric oxide (NO) content

The amount of nitric oxide (NO) was measured using a Greries reagent. Reference Example 1 Concentration of E. coli lipopolysaccharide (purchased from E. Coli serotype 055: B5, Sigma-Aldrich, Stt. Louis, MO) on cells cultured in (1) (8 × 10 ⁴ cells / sphere on 96 plate) Is 100ng / ml so that the concentration of each extract is 0.1mg / ml, 0.5mg / ml, 1.0mg / ml. After 24 hours, 50µl of the culture supernatant is collected and 50µl of grease reagent (Griess After mixing in a reagent) (1% sulfanylamide / 0.1% naphthylethylene diamine dihydrochloride / 2% phosphoric acid) in a 96-well plate, the absorbance (OD) value was measured with a microplate reader at 540 nm.

The concentration of nitrogen dioxide ions (NO ₂ ) (nitrite ion NO ₂ ⁻ ) in the sample was quantified using a sodium nitrate (NaNO ₂₎ standard curve.

As a result, it was confirmed that the mixture of each of the single extracts of mugwort, licorice, yellow lotus, and pontoon and the extract of mugwort, licorice, yellow lotus, and pontoon all inhibit NO production in the RAW264.7 cells activated in a concentration-dependent manner.

At each concentration of the mixture of mugwort single extract, licorice single extract, rhubarb single extract, soft bristle single extract, and mugwort / licorice / rhubarb / brittle extract, the production of NO induced by lipopolysaccharide was inhibited (see FIG. 1).

Table 1 shows the NO production inhibition rate according to the concentration of the extract, which shows the average value of the results of three tests in the same manner.

(2) cell viability measurement (MTT assay)

The cells were dispensed into 96-well plates, treated with concentrations of 0.1 mg / ml, 0.5 mg / ml, and 1.0 mg / ml for each extract, followed by reaction for 24 hours. Then, the culture medium was removed, and 30 占 폚 of MTT solution (3- [4,5-dimethylthiazol-2-yl] -2,5-diphenyltetrazolium bromide; 0.5 mg / ml) was added at 37 占 폚. Incubated for 2 hours in a CO ₂ incubator to produce insoluble formazan crystals.

The insoluble crystal thus produced was completely dissolved in dimethyl sulfoxide (DMSO), and then absorbance values were measured at a wavelength of 570 nm using a microplate reader. The cytotoxicity was confirmed using the measured value.

As a result, as shown in Figure 2 it was confirmed that the extract does not affect the cell viability.

Experimental Example 2. Measurement of the inhibitory effect of periodontal disease-causing bacteria of the mixture of mugwort extract, licorice extract, rhubarb extract, pontoon extract, and mugwort

Inhibition of growth of Staphylococcus aureus, the cause of periodontal disease of the mixture of mugwort extract, licorice extract, rhubarb extract, yeonja extract and mugwort / licorice / rye / yeonja extract of Example 1 The antimicrobial effect was measured to the extent.

In the following experiments, each of the extracts or a mixture of the extracts was used at a concentration of 0.5 g / ml each.

Nutrient agar plates were used to measure growth-lowering ring by the Agar Diffusion Method. The strain was prepared by activating after pre-culture at 37 ° C. for 24 hours, washing and rinsing three times with sterile water. Measure the absorbance at 550nm using a spectrophotometer, adjust the bacterial count to 1.5 (± 0.5) x10 ⁷ cells / ml, mix well by adding 100µl to 5ml of top agar maintained at 45 ℃. , Nutrient agar plate was prepared. Each extract was prepared at a concentration of 10 mg / 20 μl, soaked 20 μl on a 6 mm diameter paper disc, and completely dried in BSC (Biological Safety Cabinet, Labconco, USA). After the top agar was dried, each extract was wetted on a Nutrient agar plate, and the dried disk was raised and incubated at 37 ° C. under aerobic conditions. Growth hypotermination produced after 24 hours of cultivation was measured using vernier calipers (Mitutoyo, Japan). The experiment was repeated three times, Table 2 below shows the antimicrobial activity of the extract using growth inhibition ring, the diameter of the growth inhibition ring is expressed as the average value ± standard deviation.
