Acne is an inflammatory disease of the hair follicles and pores of the skin, mainly due to increased sex hormone secretion during puberty. In particular, the androgen, a male hormone, stimulates sebaceous glands to increase sebum secretion, and when acne bacteria invade the skin, lipid-unsaturated fatty acids are produced by lipolysis by lipase, causing acne to form hair follicles and surroundings. will (symbol bacteria et al., Journal of Dermatology, 43: 871-875, 2005). If acne is left unattended, purulent skin can develop on the face, which can lead to scarring and enlarge the pores, making the skin look like a tangerine peel. Therefore, acne can be a psychological wound to the appearance-sensitive adolescents and adults, so proper treatment is required.

Until now, the pathogenesis of acne is not clear, but there is no effective treatment. However, many antibiotics and steroids are prescribed as external skin preparations, and vitamin A is mainly used as an oral treatment. However, antibiotics are becoming a problem of resistance and safety, and steroids are effective immediately when applied for the first time, but as they are applied for longer periods of time, they increase dependency on ointments due to side effects such as enlarged capillaries, enlarged pores, and reddened face. This can be worse. In addition, in the case of vitamin A preparations, not only serious side effects such as dry skin are caused, but stability is a problem because the US FDA can give birth defects when administered during pregnancy (Akhavan A et al., Am J Clin Dermatol 4). , pp. 473-492, 2003). Therefore, there is a growing demand for the development of medicines and functional soaps or cosmetics containing natural products having an acne treatment effect in place of these preparations.

In Korea, natural products are attracting attention as alternative medicines that have reduced side effects and improved therapeutic effects. This is because, in the case of therapeutic agents using natural product extracts and components that have been used for a long time and have been proved to be harmless to humans, resistance or safety problems caused by existing therapeutic agents can be overcome. In particular, herbal functional items using natural products that have been used as herbal medicine are popular. In the case of acne, face washing is important, so if you develop soaps or cosmetics that contain natural ingredients that have antibacterial effects on acne bacteria, you can make a big profit.

Joiner ( Caesalpinia sappan L.) is an evergreen small arboreous tree, 5-10 m high. Stems have branches, small branches grey-green, with round, prominent crusts. Bird branches have short soft hairs, but later fall out. Remove the first bark (樹皮) and sapwood (邊材) was collected at any time of the year and used as the after-dried sunburns taking a core (心材) medicinal herbs (jeongboseop et al., Illustrates hyangyak Dictionary,, pp666, 1989 per Younglim).

Hereinafter, the present invention will be described in detail by the following Examples and Experimental Examples.

However, the following Examples and Experimental Examples are only illustrative of the present invention, the contents of the present invention is not limited by the following Examples, Reference Examples and Experimental Examples.

Example 1 Preparation of Joiner Extract

The seedling extract was mixed with 1 L of methanol (Methanol) in 200 g of the dried amount of the seedling (purchased by a pharmacist), and then extracted by stirring three times at room temperature for 72 hours. The extract was filtered with filter paper (Whatman, No. 2), concentrated under reduced pressure with a rotary vacuum evaporator (SB-1000, Japan) at 60 ± 2 ° C., and lyophilized to obtain 5.11 g of a seedling extract. The obtained joiner extract was dissolved in DMSO (dimethyl sulfoxide), filtered through a 0.2 μM filter (Millipore Corporation, Bedford, MA) and used as a sample of the following experimental example.

Reference Example  One. Experimental strain  And culture

P. acnes KCCM 41747 received from Korea Microbial Conservation Center was incubated in BHI culture (Difco, USA) and then mixed with glycerol (glycerol) in a ratio of 3: 7 and stored at -70 ℃. Strains stored in the freezer were activated 3 days before the start of the experiment and inoculated in a BHI agar plate (incubated in an anaerobic incubator supplied with 5% H ₂ and 95% N ₂ were used in the experiment.

Experimental Example 1. Measurement of the growth inhibitory effect of acne causative bacteria

1-1. Minimum Inhibition Concentration (MIC) Measurement by Broth Dilution Test

In order to measure the minimum inhibitory concentration (MIC) that inhibits the growth of P. acnes , which is the acne bacterium, by using the method described in the literature, experiments were performed as follows (Lee Sung-rim et al., Korea Environmental Health) Journal, 32; 192-197, 2006).

P. acnes bacteria were precultured for 24 hours by the method of Reference Example 1. The cultured bacteria were measured for absorbance at 600 nm using a spectrophotometer (TECAN, Crailsheim, Germany), prepared at a concentration of 1 × 10 ⁷ CFU / ml and 200uL was dispensed in 96-well plate (96well plate). Joiner extract was diluted to 0.5 ug / mL by diluting stepwise 2-fold dilution with the highest concentration of 500 ug / mL. Diluted joiner extracts were added to 96 well plates inoculated with test strains and cultured under anaerobic culture conditions (5% H ₂ + 95% N ₂ , 37 ° C.). After 48 hours of incubation, the absorbance was measured at 600 nm with a spectrophotometer, and the lowest concentration at which growth of acne was suppressed was determined as the minimum inhibitory concentration, which is shown in Table 1 below.

Table 1

Sample Name Minimum inhibitory concentration (MIC, ug / mL) Joiner extract 62.5

As shown in Table 1, the minimum inhibitory concentration for acne bacteria of the joiner extract was 62.5ug / mL.

1-2. Measurement of clear zone by disk diffusion test

In order to determine the clear zone of P. acnes acne bacteria by the joiner extract, the experiment was conducted using the disk method (Chomnawang et al., Journal of Ethnopharmacology, 101; 330-333, 2005).

P. acnes bacteria were pre-incubated for 24 hours using a BHI agar plate and prepared at a concentration of 1 × 10 ⁸ CFU / ml and maintained in 5 mL of top agar maintained at 45 ° C. 1 mL of each was added and mixed well, and then smeared onto a BHI agar plate. Joiner extracts were prepared at concentrations of 0.25, 0.5 and 1 mg / 25 uL, loaded 25uL each on 8mm diameter paper disks and 25uL DMSO on the control disk. The top agar was placed on a dry BHI agar plate, and the disks with the seedling extracts were raised and incubated for 48 hours under anaerobic conditions. Growth inhibition produced after 48 hours was measured using a micrometer (Mitutoyo, Kawasaki, Japan).

As a result, as shown in Figure 1, DMSO-only control showed no growth inhibitory effect on acne bacteria, whereas the seedling extract showed growth inhibition effect in a concentration-dependent manner. Therefore, it was confirmed that the extract of the joiner had an antimicrobial effect against P. acnes (propionibacterium acnes) , which is the causative agent of acne (see Fig. 1).
