Abstract

Japanese anise (Illicium anisatum L.) leaves and twigs were extracted with 50 % aqueous acetone three times. After filtration, the extracts were fractionated with n-hexane, chloroform, ethyl acetate and $H_2O$, and then freeze dried after condensation. Then antioxidation and antiviral activity were evaluated on each fractions. In the antioxidative activities, the results indicated high activity in the EtOAc soluble fraction of the leaves and the EtOAc and $H_2O$ soluble fractions of the twigs. It showed much higher antioxidative value compare to the controls, BHT and ${\alpha}$-tocopherol. In the antiviral activities, the all fractions were negative effects in HRV 1B and EV 71, but good in Influenza PR8. The activities of the crude extracts of the leaves and twigs showed more than 80% activity at the concentration of $10{\mu}g/mL$ and $50{\mu}g/mL$, respectively, and the activities of the EtOAc and $H_2O$ soluble fractions were close to 80%. Based on the above results, the extracts of Japanese anise may be applied for one of the natural biomass sources that can be used as an antioxidant and an antiviral substance.

붓순나무의 잎과 가지를 50 % 아세톤 수용액으로 추출하고, 추출된 각각의 조추출물(crude)을 n-hexane, chloroform, EtOAc와 물($H_2O$)로 분획한 후, 각각의 분획물에 대하여 항산화 활성과 항바이러스 활성 시험을 실시하였다. 항산화 활성은 붓순나무 잎의 경우 EtOAc용성 분획물에서 가지의 경우 EtOAc용성 분획물과 수용성 분획물에서 가장 좋은 활성을 보였고, 대조군으로 사용된 BHT 및 ${\alpha}$-tocopherol에 비하여 우수한 항산화 활성이 있는 것으로 나타났다. 항바이러스 활성의 경우, HRV 1B와 EV 71에서는 항바이러스 활성이 미흡한 것으로 나타났으나, Influenza PR8에서는 어느 정도 항바이러스 활성을 갖고 있는 것으로 나타났다. 특히 EtOAc용성 분획물과 수용성 분획물에서 80% 이상의 세포 생존률이 나타난 것으로 보아 붓순나무의 극성 분획물에는 항바이러스 효과를 가지고 있는 활성 물질이 존재하고 있다는 사실을 알 수 있었다. 이상의 결과를 통하여 우리는 붓순나무로 부터 얻어진 추출물이 항산화제 및 항바이러스제의 원료로 사용 될 수 있는 천연 바이오매스 자원으로써의 가능성이 있음을 제시하였다.
