초록

산사나무 목질부 및 수피부를 70% acetone 수용액으로 추출하고 목질부는 n-hexane, chloroform ($CHCl_3$), n-butanol (n-BuOH) 및 수용성 추출물로 분획하였으며, 수피부는 n-hexane, chloroform, ethylacetate (EtOAc) 및 수용성으로 분획한 후, 각 추출 분획에 대하여 항산화 및 항염활성 평가를 실시하였다. 항산화 활성은 목질부에서는 n-BuOH용성이, 수피부에서는 EtOAc용성이 가장 좋은 활성을 보였으며, 특히 수피부 EtOAc용성은 대조군으로 사용된 buthylated hydroxytoluene (BHT) 및 ${\alpha}$-tocopherol에 비하여 매우 우수한 항산화 활성을 나타냈다. 항염활성은 목질부 수용성을 제외한 모든 분획물들이 nitric oxide (NO) 생성을 억제하는 효과를 보이고 있었으며, 수피부 조추출물과 수용성 분획에서 가장 우수한 NO 생성 억제효과를 나타내었다. 이와 같은 결과를 토대로 볼 때, 산사나무 추출물은 항산화제 및 항염제로 이용될 수 있는 천연 바이오매스 자원으로써의 가능성을 나타내었다.

The wood and bark of Hawthorn tree (Crataegus pinnatifida Bunge) were immersed with 70% aqueous acetone for 3 days. After filtering, the wood extracts were fractionated with n-hexane, chloroform ($CHCl_3$), n-butanol (n-BuOH) and $H_2O$, and the bark extracts were fractionated with n-hexane, $CHCl_3$, ethylacetate (EtOAc) and $H_2O$. Then antioxidative and anti-inflammatory activities were evaluated on each fraction. Antioxidative activity indicated high activity in the n-butanol soluble fraction of wood and in the EtOAc soluble fraction of bark. Especially, the EtOAc soluble fraction of bark showed much higher antioxidative value compared to the controls, buthylated hydroxytoluene (BHT) and ${\alpha}$-tocopherol. In the anti-inflammatory activity, all of the tested fractions except the $H_2O$ soluble fraction of wood showed high inhibitory effect on nitric oxide (NO) production. Based on the above results, the extracts of hawthorn tree may be applied for one of the natural biomass sources that can be used as an antioxidant and an anti-inflammatory substance.
