피부 여드름 치료, 예방을 위한 천연물의 활성평가를 시도하였다. 335종의 약용 및 야생식물의 다양한 부위로부터 500종의 추출물을 조제하여, 여드름 원인세균인 Propionibacterium acnes에 대한 생육저지 활성을 평가한 결과, 21종 식물체에서 조제한 25종 추출물에서 활성을 확인하였다. 500종 추출물 중, 홀아비꽃대(지상부) 추출물에서 가장 강력한 활성이 나타났으며, 방기, 고삼, 오수유, 은행(씨), 상백피, 독활 및 호장근 추출물에서도 우수한 활성을 확인하였다. 특히 고삼, 상백피, 독활 등의 항여드름 활성은 기존 보고 및 민간요법과도 잘 일치하며, 홀아비꽃대 및 방기 추출물의 항여드름 균 활성은 본 연구에서 처음으로 확인하였다. 고삼을 대상으로 한 활성물질 분리결과, kuraridin과 kurarinone의 주요 활성물질임을 확인하였다. 본 연구결과는, 안정성이 확보된 식물추출물로부터 새로운 피부여드름 치료제 개발이 가능함을 제시하고 있으며, 현재 고삼 추출물 및 활성물질의 세포 독성 및 작용기전에 대한 연구가 진행중이다.

Bee venom (BV) has been used as a treatment for a wide variety of ailments such as inflammatory diseases in korean traditional medicine. Despite its well documented anti-inflammatory property, it has not been fully demonstrated regarding the influence of BV against Propionibactierium acnes (P. acnes), which promotes follicular inflammation (inflammatory acne). This study evaluated the anti-inflammatory property of BV against P. acnes in vivo. To induce inflammation in vivo using P. acnes, $1{\times}10^7$ CFU of living P. acnes were intradermally injected into the ear of mice. BV (1, 10, 100 ${\mu}g$) in vaseline was applied epicutaneously on the ear resulting in P. acnes-induced ear swelling and inflammation. Epicutaneous administration of BV with P. acnes decreased the number of infiltrated inflammatory cells and inflammatory cytokines in the ear, thereby relieving P. acnes-induced ear swelling and granulomatous inflammation, especially at the dose of 1 ${\mu}g$ of BV. In this report, we demonstrated the therapeutic effects of BV on P. acnes-induced inflammation in vivo using the mouse model. These data highlight the potential of using BV as an alternative treatment to the antibiotic therapy of acne vulgaris.

Objective : The purpose of this study is to investigate the antibacterial activity of Saussurea lappa for the applications of herb-based extracts to both cosmetic and medicinal industries. Methods : Antibacterial activity of ethanol extract of Saussutes lappa (ESL) was assessed using agar diffusion and broth dilution methods, and determined by whether clear zone was formed around paper disc and in terms of the size (mm) of clear zone, Results : ESL provided activity against Staphylococcus aureus KCTC 1927 in concentration of 1 mg/ml with an clear zone of 16 mm, and showed an activity against Staphylococcus epidermids KCTC 1917 in concentration of 1 mg/ml with an clear zone of 18mm. Moreover, the minimum inhibitory concentration (MIC) of ESL against S. sureus and S. epidermidls were 1 mg/ml for both bacterial species. However, ESL showed no growth inhibition against Pseudomonas aeruginosa KCTC 12513, Enterobactet aerogenes KCTC 2190, Escherichia coli KCTC 2571, Salmonella typhimurium KCTC 1925 and Propionibacterium acnes KCCM 41747. Conclusions : Antibacterial activity of ESL against Staphylococcus sureus and Staphylococcus epidermids causing eye and skin diseases was proved. The result suggest that ESL may be useful as a natural preservative on behalf of synthetic preservatives.

본 연구는 녹나무과 10종의 추출물이 Propionibacterium acnes의 억제활성에 미치는 영향을 분석하여 새로운 천연 항균소재를 개발하기위해 수행되었다. 실험재료는 완도와 제주도에서 채집하였으며, 부위(잎, 가지), 용매(증류수, 80% 에탄올, 100% 메탄올) 및 초음파 추출시간(15, 30, 45분)에 따른 조추출물의 항균활성을 agar diffusion method로 조사하였다. 대조구로는 합성항균제인 methylparaben과 phenoxyethanol 0.4, 1, 2, 4 mg/disc를 사용하였다. 연구에 사용된 10종의 모든 추출물에서 억제활성을 보였으며, 여드름균에 대한 항균작용을 확인할 수 있었다. 이 중 월계수는 80% 에탄올에 45분간 추출한 조건에서 20.2 mm의 생육억제환을 나타내어 가장 우수한 여드름균에 대한 항균작용을 확인할 수 있었다. 월계수 잎을 100% 메탄올을 용매로 초음파 30분 추출한 다음n-hexane, chloroform, ethyl acetate, n-butanol 그리고 water 순으로 용매 분획하여 항균활성을 비교분석하였다. 결과, butanol 분획물을 제외한 모든 분획물에서 10.0 mm 이상의 억제환이 형성되었다. 그중 ethyl acetate 분획물에서 억제환이 13.3 mm로 가장 컸으며, 조 추출물(10.2 mm)과 대조구인 phenoxyethanol (12.5 mm)에 비해서도 유의적으로 우수한 억제활성을 나타내었다.

10종 양치식물의 지상부와 지하부 메탄올 추출물을 대상으로 Bacillus subtilis, Escherichia coli, Listeria monocytogenes, Propionibacterium acnes, Streptococcus mutans, Streptococcus sobrinus 등 병원성 미생물에 대한 항균활성을 broth microdilution법과 paper diffusion법을 이용하여 분석하였다. 억제환이 15 mm 이상으로 나타난 추출물을 대상으로 0.125, 0.25, 0.5 1, $2\;mg{\cdot}mL^{-1}$의 농도에서 3일 동안 각 미생물의 생육 억제에 미치는 영향을 분석하였다. 그 결과, B. subtilis, E. coli, L. monocytogenes에 대해서는 꿩고비의 지하부 추출물에서 억제활성이 가장 우수하였으며, 살균처리하지 않은 조추출물 상태에서 $2\;mg{\cdot}mL^{-1}$의 농도에서 72시간 이후에도 각 39, 33, 58%의 억제활성을 보였다. P. acnes에 대해서는 꿩고비 지상부 추출물이 가장 우수한 항균활성을 보였으나, 15 mm 미만의 억제환을 보여 항균력이 약한 것으로 나타났다. S. mutans와 S. sobrinus에 대해서는 다수의 양치식물이 비교적 우수한 항균활성을 보여 양치식물의 추출물은 전반적으로 Streptococcus에 대한 감수성이 높은 것으로 생각되었다. 그러나 고비의 지하부 추출물이 $2\;mg{\cdot}mL^{-1}$의 농도에서 72시간 후 각 28, 39%, 그 외의 추출물은 10% 내외의 낮은 항균활성을 보여 10종의 양치식물 추출물 중에는 Streptococcus에 대하여 뛰어난 항균력을 보이는 추출물은 없는 것으로 생각되었다.

Acne vulgaris, the most common skin disease. can be formed as only a few comedons or severe inflammatory lesions. The pathogenesis of acne involves various factors; excessive androgen, excessive sebum production, abnormal alteration of follicular epithelium, proliferation of Propionibacterium acnes, and inflammation. We investigated acne therapy using oriental herbs described in the Korean traditional medical book(Dong-ui-bo-gam). Oriental herbs(Angelica daurica, Arctium lappa, Coptidis rhizoma, and Glycyrrhiza glabra) were chosen based on their respective property of sebum control, anti-inflammatory activity, and anti-bacterial activity. We examined the effect of acne treatment, in terms of chemotactic inhibition, lipogenesis inhibition, and anti-bacterial activity for P. acnes. 1. Neutrophil chemotaxis assay; P. acnes secrete chemotactic factors and other pro-inflammatory extracellular products. Neutrophil chemotactic activity of P. acnes was measured by 48-well chemotaxis method. Angelica daurica clearly suppressed chemotactic activity of P. acnes. 2. Using sebaceous gland of hamster ear lipogenesis assay; Sebaceous lipogenesis was measured using ear biopsies by incubation or $C^{14}$-acetate in culture media. The $C^{14}$-labeled lipids were extracted and determined by liquid scintilation counting. Coptidis rhizoma markedly inhibited sebum production. 3. Anti-bacterial assay for P. acnes(MIC test); Glycyrrhiza glabra showed anti-bacterial activity. P. acnes did not develop resistance against Glycyrrhiza glabra. Retinoids are effectively to inhibit sebum production and regulate follicular keratinization process, with little anti-inflammatory activity. Angelica daurica suppressed neutrophil chemotaxis, Coptidis rhizoma inhibited sebum production, and Glycyrrhiza glabra showed anti-bacterial activity against P. acnes. A combined formulation of Angelica daurica, Coptidis rhizoma. and Glycyrrhiza glabra is expected to provide effective acne treatment.

The antibacterial activity against Propionibacterium acnes (P. acnes), $5{\alpha}-reductase$ inhibition and comedolytic effects are the important pharmacological target sites of antiacne drughs. We previously reported on the antibacterial activities against P. acnes by natural products. In the present study the screening of $5{\alpha}-reductase$ inhibition and comedolytic effects from natural products were performed. Seven natural products such as Angelica koreana, Sophora flavescens, Prunus persica, Bombyx mori, Areca catechu, Galla rhois and Gleditschia koraiensis perfectly inhibited the activity of $5{\alpha}-reductase$ at the concentration of 0.01% (w/v). Sixteen natural products which were shown to have the potent antibacterial activities against P.acnes or $5{\alpha}-reductase$ inhibition activities were assayed for the comedolytic test. In the results of comedolytic effects on experimentally-induced comedones (EIC), Sophora flavescens showed the strongest comedolytic effect on EIC, and Polygonum cuspidatum and Angelica koreana showed stronger comedolytic effects on EIC than azelaic acid used for a positive control at the concentration of 3% (w/v). These results suggest that several natural products including Sophora flavescens can be developed as noble antiacne agents.
