Abstract

This study was carried out to determine the inhibitory effects of solvent extracts from Sargassum hemiphyllum on growth of cancer cell lines (AGS human gastric adenocarcinoma and HT-29 human colon cancer cells) and production of lipid peroxides. Inhibitory effects of acetone with methylene chloride extract from S. hemiphyllum on the growth of AGS and HT-29 cancer cells were increased as dose dependent patterns (p<0.05). The methanol extract was more effective on inhibition of growth of AGS. The treatments of hexane, 85% aq. methanol, butanol and water fractions significantly inhibited the growth of cancer cells (p<0.05) and the inhibitory effect was stronger in HT-29. In DCFH-DA (dichlorodihydrofluorescin diacetate) assay, acetone with methylene chloride and methanol extracts showed a stronger inhibitory effect on the production of cellular lipid peroxides (p<0.05) compared with the butanol and hexane fractions. These results indicate that the consumption of S. hemiphyllum may be recommended as a potent functional food for preventing cellular oxidation and cancer.

본 연구에서는 갈조류에 속하는 짝잎모자반을 용매별로 추출하여 인체 위암 및 결장암세포에 대한 증식 억제 및 지질 과산화물 생성 억제효과에 대해 검토하고자 하였다. Acetone/methylene chloride 추출물(A+M) 및 methanol 추출물(MeOH)을 인체 위암세포에 처리했을 때 농도 의존적으로 암세포 증식을 억제하였고(P<0.05), MeOH 추출물의 경우 인체 결장암 세포에 비해 위암세포에 대한 증식 억제효과가 높았다. 분획물들인 hexane, BuOH, 85% MeOH, water 분획물을 5 mg/ml의 농도로 인체 위암 및 결장암세포에 처리했을 때 암세포의 성장을 크게 억제시켰으며(P<0.05) 위암세포와 비교해 볼 때 결장암 세포에서 보다 높은 암세포 증식 억제효과를 보였다. A+M 추출물 및 MeOH 추출물과 각 분획물들을 10mg/ml의 농도로 HT-1080 섬유육종 세포에 처리하였을 때, 지질 과산화물의 생성을 억제시키는 활성을 나타내었다(p<0.05). A+M 추출물과 MeOH 추출물 처리군은 blank군과 control군과 비교하였을 때, 측정 시간 120분 동안 계속적으로 높은 세포내 지질 과산화물 생성 억제 능력을 나타내었으며(p<0.05), BuOH 및 hexane 분획물들을 처리한 경우에서는 A+M 추출물과 MeOH 추출물 처리군들보다는 다소 낮은 활성을 나타내지만, control군에 비해 지질 과산화물의 증가율이 현저히 낮았음을 관찰할 수 있다(p<0.05). 이상의 결과로부터 짝잎모자반의 추출물 및 각 분회물들은 인체 암세포의 증식을 크게 억제하였으며 지질 과산화물 생성을 억제시켜 우수한 산화 방지 효과가 있음을 확인할 수가 있었다.
