단삼 메탄올 추출물의 항혈전 및 항산화 효과를 확인하기 위하여 혈소판의 응고 억제효과, 혈장응고시간의 연장, 혈전용해 활성으로 항혈전 효과를 고찰하였으며 DPPH radical 소거능을 측정하여 항산화 효과를 검토하였다. 그 결과, 단삼의 메탄올 추출물은 항혈전과 항산화에 효과가 있는 것으로 나타났다. 이 추출물은 혈소판응고 억제, 혈액응고시간 연장 및 혈전용해 활성에 모두 효과가 좋은 것으로 나타났으며, 폴리페놀 함량이 높고 DPPH radical 소거능도 매우 좋았다. 이로서 단삼의 높은 DPPH radical 소거능이 항혈전 효과에 영향을 미치는 것으로 사료되며, 정확한 효과 및 혈소판의 기능을 조절하는 기전에 대한 연구는 이 결과들을 바탕으로 현재 진행 중에 있다.

본 연구에서는 분석용 HPLC를 사용하여 단삼(Salvia Miltiorrhiza Bunge; SMB)의 추출물로부터 Tanshinone IIA (TIIA)를 분리하였다. 우선 유기용매를 사용하여 추출 및 전처리한 단삼 추출액으로부터 HPLC를 사용하여 TIIA을 분석하였으며, 고순도의 TIIA을 분리하기 위한 최적의 분석조건을 실험적으로 구하였다. 모든 단삼 시료들은 메탄올, 에틸아세테이트, 에탄올 등과 같은 유기용매로 추출하고 비교 분석하였다. 실험결과에 의하면 추출용매로 메탄올을 사용한 경우, 단삼으로부터 TIIA의 추출효율이 가장 우수 하였다. 또한 TIIA를 분석하기 위한 조건으로는 $C_{18}$ 컬럼을 사용 하였고, 이동상은 물과 메탄올을 사용하여 주로 등용매 용리를 적용하였을 때, SMB 1 mg에 $2.154{\mu}g$ TIIA를 분말로 추출하였다.

Methanol extract of Salvia miltiorrhiza Bunge (Labiatae) root was investigated to research the anti-oxidative activity, by using a Caenorhabditis elegans model system. The methanol extract of this plant showed significant DPPH radical scavenging and superoxide quenching activities. Ethyl acetate soluble fraction of the methanol extract that showed the most potent DPPH radical scavenging and superoxide quenching activities. The ethyl acetate fraction was tested on its activities of superoxide dismutase (SOD), catalase, and oxidative stress tolerance in C. elegans. Furthermore, in order to see if regulation of stress-response genes is responsible for the increased stress tolerance of the ethyl acetate fraction treated C. elegans, we checked SOD-3 expression using a transgenic strain. Consequently, the ethyl acetate fraction of S. miltiorrhiza root increased the catalase and SOD activities in a dose-dependent manner in C. elegans. Besides, the ethyl acetate fraction-treated CF1553 worms showed higher SOD-3::GFP intensity than the non-treated ones.

We screened natural products to find compounds with anti-osteoporotic potential using a coculture-based system by which osteoclast differentiation is effectively achieved. We found that methylene chloride soluble fraction of the root of Salvia miltiorrhiza Bunge (Labiatae) suppressed osteoclast differentiation. Five tanshinones, tanshinone IIA (1), tanshinone I (2), cryptotanshinone (3), 15,16-dihydrotanshinone I (4), and ferruginol (5) were subsequently isolated from fraction. Among the five compounds, compounds 1-4 reduced the formation of TRAP­positive multinuclear osteoclasts. These results suggest that the identified tanshinones may be useful candidates for development of therapeutic agents to treat osteoporosis and other bone-resorptive diseases.

Acute toxicity of a combined preparation of the standardized extracts Scutellaria baicalensis GEORGI and Salvia miltiorrhiza BUNGE in a ratio of 3:1 was examined in male and female ICR mice. Mice were treated with the test substance intragastrically at a dose of 0 mg/kg, 5 mg/kg, 50 mg/kg, 500 mg/kg or 2,000 mg/kg and observed for two weeks. No death or abnormal clinical sign was shown during the observation period. Also there were no difference in net body weight gain, organ weight, and gross pathological findings at the terminal sacrifice. The results suggested that acute oral toxicity of a combined preparation of the standardized extracts is very low at the conditions employed in this study.

단삼(Salvia miltiorrhiza) 추출물의 치주질환유발 세균에 대한 생육저지 활성 및 collagenase저해 활성을 측정하였다. 단삼 에탄올 추출물은 치주질환유발 세균에 대해 우수한 생육저지 활성을 나타내었다. 유기용매 분획물중, hexane에서 생육억제능이 가장 우수하였다. 치주질환유발 세균 C. curvus, C. rectus, E. corrodens, F. nucleatum, P. gingivalis, P. intermedia 및 W. succinogenes에 대한 단삼 추출물의 최소생육저해농도(MIC)는 200,50,50,250,150,250및 200 ${\mu}g$/ml로 각각 우수한 생육억제능을 나타내었다. 단삼 유기용매 분획물의 collagenase저해 활성은 동일 농도의 minocycline에 비해 우수한 저해 활성을 나타내었으며, chloroform분획물의 경우 88.2%의 저해 활성을 나타내었다.

This study was conducted in an effort to evaluate the antimicrobial activity and antibiotic-resistant gene regulation from Saliva miltiorrhiza Bunge on methicillin-resistant Staphylococcus aureus (MRSA). A variety of solvent fractions and methanol extracts of S. miltiorrhiza Bunge were tested in order to determine its antimicrobial activities against S. aureus and MRSA. As a result, the hexane fraction of S. miltiorrhiza Bunge evidenced the highest levels of antimicrobial activity against S. aureus and MRSA. The MICs of the hexane fraction against various MRSA specimens were $64. The hexane fraction evidenced inhibitory effects superior to those of the chloroform fraction. The results showed inhibition zones of hexane (16 mm) and chloroform (14 mm) fractions against MRSA KCCM 40511 at $1,000{\mu}g/disc$. The hexane and chloroform fractions inhibited the expression of the resistant genes, mecA, mecR1, and femA in mRNA. Moreover, the results of Western blotting assays indicated that the hexane and chloroform fractions inhibited the expression of the resistant protein, PBP2a. These results reveal that the hexane and chloroform fractions of S. miltiorrhiza Bunge may prove to be a valuable choice for studies targeted toward the development of new antimicrobial agents.

Background: Salvia miltiorrhiza Bunge has been used in traditional medicine. The type of light source has an effect on the growth properties and composition of functional compounds in plants. In this study, we analyzed the effects of different artificial light sources on the growth characteristics as well as antioxidant and antimicrobial activities of S. miltiorrhiza. Methods and Results: Seedlings of S. miltiorrhiza were grown under various artificial light sources, including fluorescent light (FL), light emitting diode (LED), and microwave electrodeless light (MEL), for 8 weeks. Growth characteristics were the best in plants treated with MEL. DPPH scavenging activity of the shoot was more pronounced with the FL treatments, while the roots were more active in plants grown under single wavelength lights (i.e., blue and red LEDs). Among the different light source treatments, the blue LED resulted in a higher total phenolic content in the plants. Furthermore, growing plants growth under the red LED enhanced their total flavonoid content. Notably, the antimicrobial properties of plants varied significantly between light source treatments in this study. Except for E. coli, all the tested microorganisms were susceptible to the plant extracts. Conclusions: The type of light source may be an important parameter for the enhancement of plant growth and functional compounds in S. miltiorrhiza.

단삼(Salvia miltiorrhiza Bunge)은 우리나라에서 전통적으로 부종, 관절염, 간염 등과 같은 염증질환의 치료에 사용해왔다. 본 연구에서는 단삼 메탄올 추출물을 이용하여 구강미생물에 대한 항균활성을 확인하였다. 그 결과 메탄올추출물은 실험 되어진 모든 구강미생물에서 강한 항균활성을 나타내었다(MICs, 8 to $64\;{\mu}g/mL$; MBCs, 16 to $64\;{\mu}g/mL$). 추가적으로 ampicillin이나 gentamicin과의 병용투여서 최소억제농도(MIC)와 최소살균농도(MBC)가 감소하는 병용효과를 나타내었다. 더불어 메탄올추출물 단독 사용시 보다 항생제와 병용투여시 빠른 사멸효과를 보였다. 결론적으로 단삼 메탄올추출물이 치아우식을 유발하는 많은 세균들에 대한 항균효과가 뛰어남을 확인 할 수 있었으며, 안정성이 높은 천연 치아우식예방제로서의 개발가능성을 확인하였다.
