The Effects on Antimicrobial and Cytotoxicity of Hijikia Fusiformis Fraction

In this study, we investigated antimicrobial and cytotoxicity effects to each· fraction extracted from Hizikiafusifonnis (HF), which were extracted methanol (HFM) and then the extract was fractionated into four different types: hexane (HFMH) , methanol (HFMM) , bulanol (HFMB) and aquous (HFMA) partition layers. We determined the cytotoxic effect of these layers on human cancer cells by MIT assay. Among various partition layers of HF, the HFMB and HFMM were showed the strong cytotoxic effects on cancer cell lines we used. The quinone reductase (QR) induced activity of the HFMB on HcpG2 cells at concentration was 2.63 times more effective compared to the control value of 1.0. Although further studies are needed, the present work suggests that HF maybe a chemopreventive agent for the treatment of human cancer cells.
