초록

비단풀 물 추출물을 제조하여 DMSO 용매에 녹인 후 항산화활성과 항암활성을 조사하였다. 항산화활성을 10, 100, 250, 500, $1,000{\mu}/mL$의 농도에서 측정하였을 때, 총 페놀함량, 라디칼 소거능, 환원력은 각각 농도에 의존하여 결과값이 향상되었으며, $1,000{\mu}g/mL$ 농도에서 각각 $659.2{\mu}M$, 86.0%, 1.084의 수치로 높은 활성을 보였다. 그리고 comet assay에서는 비단풀을 5, 10, 25, $50{\mu}g/mL$의 농도로 백혈구에 처리한 후 hydrogen peroxide $200{\mu}M$의 농도로 처리하여 DNA손상을 유도한 결과 손상된 DNA tail 부분의 DNA 함량을 측정한 % fluorescence in tail이 각각 62.3, 39.8, 24.8, 16.4%로 83.0%인 $H_2O_2$ 처리 양성 대조구에 비해 유의적으로 감소하였다. 항암효과를 조사하기 위한 MTT reduction assay 방법에서는 추출물을 처 리 하지 않은 대조구와 비단풀 물 추출물의 암세포 성장억제효과 비교시 대장암 유래의 암세포주 HT-29에서는 $10{\mu}g/mL$농도에서 49%의 생존율을 나타내었고, 유방암 유래의 암세포주 MCF-7에서 역시 $10{\mu}g/mL$농도에서 130%의 생존율을 확인하였다. 현재 한약재를 비롯한 농산물 유래의 추출물이 항산화효과와 항암효과를 보이는 연구가 많이 보고되고 있으며, 비단풀도 하나의 천연물 소재로 생리활성물질 탐색에 중요한 천연자원이 될 수 있는 가능성을 확인할 수 있었다.
