Description

Composition for improving microbial flora containing extract of Allii Fistulosi bulbus}

The present invention relates to a composition for improving the microbial flora comprising a total back extract as an active ingredient.

The human body is a complex and active ecosystem, and various microorganisms exist in the stomach and skin of the human body. The microbial community present in the stomach and skin is called a microbial flora, and 500 to 1000 or more different microorganisms symbiize and form a microbial flora. The intestinal microflora present in the stomach synthesizes vitamins and supplies it to the human body, and serves to suppress infection by pathogenic microorganisms introduced through contaminated food.

Microorganisms that live on the surface of the skin affect physiological activities such as human growth, nutrition, immunity, resistance to pathogenicity, etc., and block the invasion of external microorganisms, especially pathogenic microorganisms. In addition, microorganisms residing in the skin are known to perform the pH control and skin barrier function of the skin, change the skin lipid content to affect the skin condition. For example, in the case of atopic patients it has a horny skin, dry the ceramide content of the horny layer is reduced, and cracks in these atopic patients known to be changed by the skin microflora is extremely Staphylococcus aureus (Staphylococcus aureus) (Non-Patent Document One).

Since microorganisms have microorganisms that have a beneficial effect on the human body, it is necessary not only to remove (sterilize) all the microorganisms, but also to promote the growth of beneficial bacteria while suppressing the growth of harmful bacteria.

The present inventors have completed the present invention as a result of performing research for improving the microbial flora using natural products.

One aspect of the present invention to achieve the above object provides a composition for improving microbial flora comprising a total back extract as an active ingredient.

As used herein, the term "microbial flora" refers to a microbial community including all bacteria, fungi and other prokaryotes present in the human body, and mainly lives in the stomach and skin. For example, intestinal yuikgyun that live in the stomach has a Lactobacillus bacteria (Lactobacillus), Bifidobacterium (Bifidobacterium), harmful bacteria in the intestines is Clostridium (Clostridium) are known.

As used herein, the term 'improvement' means a state in which the composition of the microbial flora is changed in a direction beneficial to the human body due to the administration of the composition.

Chongbaek ( Allii Fistulosi bulbus) used as an active ingredient of the composition for improving the microbial flora of the present invention refers to a medicinal herb made of fresh scales of green onion Allium fistulosum Linne (lily and Liliaceae). It is known to act as a good way to nourish and act on colds, headaches caused by colds, and abdominal pain. However, the efficacy of microbial flora improvement is not known.

In one embodiment of the present invention, the total bag extract may be prepared according to conventional methods known in the art.

Hereinafter, one or more embodiments will be described in more detail with reference to Examples. However, these examples are provided to illustrate one or more embodiments illustratively and the scope of the present invention is not limited to these examples.

Example 1 Preparation of Total White Extract

To 5 g of the total bag, 50 ml of 95% ethanol or methanol (medicinal: solvent ratio 1:10) were added and shaken for 3 hours in a 50-temperature water bath to obtain a primary extract. The primary extract was filtered through filter paper, and the filtered extract was concentrated and dried to prepare a total bag extract. 50 mg of dried ginseng extract was dissolved in 1 ml of each extraction solvent, and solids which were not dissolved in the solvent were removed by centrifugation and only the supernatant was used as a sample.

Example 2 Growth of Skin Microorganisms by Total White Extract

2-1. Microbe and Culture Media

Staphylococcus aureus ( Staphylococcus aureus ; hereinafter referred to as S. aureus ) is used as a skin harmful bacterium, and Staphylococcus epidermidis (Sermatosclerosis; hereinafter S. aureus ) is used as a skin beneficial bacterium . epidermidis ).

S. aureus KCTC 1916 and S. epidermidis KCTC 1917 used in the experiment were purchased from the Korean Collection for Type Cultures (Korea). The medium composition used for the culture of the two microorganisms is shown in Table 1 below.

S. epidermidis
KCTC 1917 NB Badge
(100 ml) Nutrient Broth 0.8 g (Agar) 1.5 g water Replenish to a total volume of 100 ml S. aureus
KCTC 1916 TSB badge
(100 ml) Tryptic Soy Broth 3.0 g (Agar) 1.5 g water Replenish to a total volume of 100 ml

2-2. Growth Changes of Individual Skin-resident Microorganisms by Extracts

S. aureus KCTC 1916 strain stock was plated on TSB (Tryptic Soy Broth, Becton Dickinson and Company, USA) agar plates and incubated at 37 ° C. for 24 hours. A single colony was then inoculated in 5 ml of TSB liquid medium and preincubated overnight at 37 ° C. and 250 rpm. The precultured S. aureus KCTC 1916 strain was inoculated in 20 ml of TSB liquid medium so that the OD ₆₀₀ was 0.05, and 200 µl (1% (v / v)) of total bag methanol extract was added. The control group added methanol at a concentration of 1% (v / v) instead of the total bag extract. Subsequently, the degree of growth was confirmed by measuring absorbance at 600 nm using an Optizen 2120 UV plus spectrophotometer (Mecasys Co., Ltd., Daejeon, Korea) every 1 hour while incubating at 37 ° C. and 250 rpm.

S. epidermidis KCTC 1917 In addition, the stock was cultured in the same manner as above, except that the stock was grown on NB (nutrients broth, Becton Dickinson and Company) agar plates, and the growth was measured.

As a result, as shown in FIG. 1, the growth rate of S. epidermidis was increased and the growth rate of S. aureus was decreased by the methanol extract of baekbaek. Specifically, the doubling time of S. epidermidis decreased about 33.31% in the total bag extract treatment group (51.50 minutes) compared to the control group (77.22 minutes). On the other hand, the doubling time of S. aureus increased about 5.07% in the total bag extract treatment group (36.9 minutes) compared to the control group (35.12 minutes).

2-3. Growth Changes of Skin-resident Microorganisms by 95% Ethanol Extracts

Microorganisms were precultured in the same manner as in Example 2-2, and the precultured S. aureus KCTC 1916 strain and S. epidermidis KCTC 1917 strain were mixed and inoculated in 20 ml of NB liquid medium such that OD ₆₀₀ was 0.05. 200 μl (1% (v / v)) of 95% ethanol extract (0.5 g / L) was added, and the control group was added with 1% (v / v) ethanol at 37 ° C. and 250 rpm for 3 hours. Incubated. Thereafter, 100 μl of the culture solution was plated on an NB agar plate, and cultured at 37 ° C. for 24 hours to confirm CFU (Colony forming unit).

As a result, as shown in Figure 2, it was found that the growth of S. aureus was significantly reduced by 95% ethanol extract treatment, and the growth of S. epidermidis was kept constant.
