본 연구는 Phellinus gilvus(PGE), Phellinus linteus (PLE) 그리고 Phellinus baumil(PBE)의 열수추출물에 대하여 SRB법과 MTT법으로 종양세포주(Sarcoma 180과 P388)를 이용하여 항암활성을 비교ㆍ평가하였다. 종양세포주는 PGE, PLE, PBE(7., 15, 30 ug/ml) 그리고 Doxorubicin(DOX)(0.001～10 mM)으로 처리되었다. 그 결과 DOX, PGE 그리고 PLE는 종양세포주에 대하여 농도의존적으로 억제하는 결과를 보였지만, PBEssm 30 ug/ml의 농도에서만 억제되는 항암활성을 보여주었다. 결론적으로 이 연구에서 사용된 PGE, PLE 및 PBE는 Sarcoma 180과 P388에 항암활성을 보여주었다. PLE는 sarcoma 180종양세포에 가장 효과가 뛰어났으나(p<0.05), SRB법에서는 PGE가 P388에 대해 가장 큰 항암활성을 나타내었다(p<0.05).
This study was undertaken to investigate comparative anti-tumor activity of water extracts of Phellinus gilvus (PGE), Phellinus linteus (PLE), and Phellinus baumii (PBE) in vitro. The anti-tumor activity in the present study was evaluated by sulforhodamine B (SRB) and microtetrazolium (MTT) assay in terms of cell survival level. The tumor cells (sarcoma 180 and P388) were treated with PGE, PLE, and PBE (7.5, 15, and 30 $mu extrm{g}$/ml) and Doxorubicin (DOX) (0.001~10 $mu extrm{M}$). The results showed that DOX, PGE, and PLE inhibited proliferation showing a dose-dependent manner against both tumor cells. However, PBE was inhibited by the only 30 $mu extrm{g}$/ml in both cells proliferation. In conclusion, all of PGE, PLE, and PBE used in this study have shown anti-tumor activity against both sarcoma 180 and P388. Among them, PLE was the most effective in anti-tumor activity against sarcoma 180 (p<0.05) and PGE was against P388 in SRB assay. PLE, however, was against P388 (p<0.05) in MTT assay.
