초록

본 연구에서는 마의 부가적인 생리활성 탐색을 위해 건조 마로부터 메탄올 추출물을 조제하고, 이로부터 헥산, 에틸아세테이트, 부탄올의 다양한 유기용매 분획물 및 물 잔류물을 조제하여 각각의 항균, 항혈전 및 항산화 활성을 평가하였다. 마 추출물의 66.7%는 물 잔류물로서, 메탄올 추출물의 상당량이 수용성 성분임을 확인하였으며, 총 폴리페놀 및 총 플라보노이드 함량은 에틸아세테이트 분획에서 가장 높게 나타났다. 항균 활성의 경우, 에틸아세테이트 분획물 $500\;{\mu}g/disc$에서 Staphylococcus aureus를 제외한 실험세균 모두에서 우수한 항세균 활성이 나타났으며, 항진균 활성은 모든 시료에서 나타나지 않았다. 항혈전 활성은 메탄올 추출물에서 우수하였으며, 4.8 mg/mL 농도에서 99.5초의 트롬빈 타임을 나타내어 아스피린과 동일 활성을 위해서는 3.2배 농도가 필요하였다. 메탄올 추출물 및 유기용매 분획물의 항산화 활성 평가 결과, 에틸아세테이트 분획이 $80.5\;{\mu}g/mL$의 $IC_{50}$를 나타내어 우수한 DPPH 소거능을 나타내었으며, SOD 유사활성은 vitamin C의 43%, 환원력의 경우 BHT의 82,7%를 나타내어 매우 강력한 항산화 활성 물질을 포함하고 있음을 확인하였다.

Yam (Dioscorea batatas Decne) has been recognized as healthy food due to its various biological activities, such as anti-obesity, anti-constipation, anti-proliferation, anti-mutagenic activity, and decrease of blood glucose and cholesterol level. In this study, the methanol extract and its organic solvent fractions were prepared from dried Dioscorea batatas Decne, and their antimicrobial, antithrombin, and antioxidant activity were evaluated, respectively. The 66.7% of methanol extract was fractioned into water residue, and most of total-polyphenol/total-flavonoids were found in ethylacetate fraction. This ethylacetate fraction at $500\;{\mu}g/disc$ concentration showed strong antibacterial activity against gram-negative and gram-positive bacteria, except Staphylococcus aureus. Antifungal activity was not observed in methanol extract and its fractions. But, strong antithrombin activity was found in methanol extract. At 4.8 mg/mL concentration, thrombin time was 99.5 sec, which is coincides with 30% activity of aspirin, a commercial available antithrombosis agent. The ethylacetate fraction showed strong DPPH scavenging activity ($IC_{50}$ of $80.5\;{\mu}g/mL$), compared to vitamin C ($IC_{50}$ of $15.2\;{\mu}g/mL$). Also, the ethylacetate fraction showed strong SOD-like activity and reducing power, which are coincide with 43% of vitamin C and 82.7% of butylated hydroxytoluene activity, respectively.
