Abstract

Cymbidium is one of perennial herbs belonging to the Orchidaceae and is known as a medicinal plant. However, its scientific data are insufficient. The purpose of this study is to extract from root and stem of Cymbidium, to investigate the biological effects of them. Cymbidium antibacterial effects of the extracts were performed by antibacterial test against Staphylococcus aureus (S. aureus), Staphylococcus saphrophyticus (S. saprophyticus), Proteus vulgaris (P. vulgaris) and Klebsiella pneumonia (K. pneumonia). Antioxidant effects of the extracts were carried out by DPPH radical scavenging. Total phenolic contents were also determined. Moreover, Cell viability of extracts against MTT assay was cell viability against HepG2 cell and also measures Cholesterol adsorptivity of extracts. In this study, the extracts inhibited the growth of bacteria. Particularly Cymbidium root extracts by only ethanol extraction showed highest antimicrobial effect against S. aureus. The Cymbidium stem extracts by both ethanol extraction and sonication for 1 hour had higher antioxidant activites as well as total phenolic contents. Cell cytotoxicity showed higher than $50{\mu}g/mL$. Cholesterol adsorptivity showed lower than 20%. These results suggest that the Cymbidium might be a source of anti-bacterials and anti-oxidants.

심비디움은 난초과(orchidaceae)에 속하는 다년생 초(perennial herb)로 약용 식물로 알려져 있으나 이에 대한 과학적 자료가 부족한 실정이다. 본 연구의 목적은 심비디움의 뿌리, 줄기로부터 추출하여 생리 활성을 비교 분석하고자 한다. 심비디움 추출물의 항균 효과는 균 종별 특이성을 규명하기 위해 실험 균주는 그람 양성균 대표로 Staphylococcus aureus (S. aureus)와 Staphylococcus saphrophyticus (S. saprophyticus), 그람 음성균 대표로 Proteus vulgaris (P. vulgaris)와 Klebsiella pneumonia (K. pneumonia)를 사용하였다. 항산화 효과는 DPPH 라디칼 소거능 및 총 페놀 함량 시험을 수행하였다. 또한 간세포에 대한 세포독성 및 콜레스테롤 흡착능 시험을 수행하였다. 심비디움 추출물을 농도 별로 처리하여 균 성장 억제를 확인해본 결과, 심비디움 뿌리 에탄올 추출물에서 S. aureus에 대한 항균효과를 확인하였으며, 심비디움 줄기 에탄올 추출물 및 1시간 음파처리를 한 심비디움 줄기 에탄올 추출물에서 높은 항산화 효과를 확인하였다. 간세포에 대한 세포 독성은 $50{\mu}g/mL$이상의 농도로 확인하였으며, 콜레스테롤 흡착능은 20% 미만으로 미비한 결과를 확인하였다. 본 연구를 통해 심비디움 추출물의 항균 및 항산화 효과를 확인하였으며, 천연 항균 및 항산화 소재로 가능성이 높을 것으로 사료된다.
