Purpose: Breast cancer is the most common disease in Korean women. Despite remarkable improvements in treatment strategies against various cancer during the past 40 years, breast cancer still remains as one of the main causes of cancer mortality among women in the whole world. This study was carried out to investigate antioxidative and anti-proliferative effects on MCF-7 human breast cancer cells of Ikiyangyoung-Tang extract.
Methods: We measured a content of polyphenol and flavonoid in the Ikiyangyoung-Tang extract, eliminative ability of DPPH radical, ABTS free radical and hydrogen peroxide, antioxidative effects of linoleic acid, cytotoxicity on MCF-7 human breast cancer cells. MCF-7 cells were cultured in Dulbecco’s modified Eagle’s medium/F12(DMEM/F12) supplemented with 10 % fetal bovine serum(FBS; Gibco) and antibiotics.
Results: The extract of Ikiyangyoung-Tang contains polyphenol of 168.3${\pm}$12.8 ${\mu}$g/mg and flavonoid of 84.3${\pm}$3.4 ${\mu}$g/mg. Above results show profitable abilities of elimination of ${\alpha}$-${\alpha}$-Diphenyl-${\beta}$-picrylhydrazyl(DPPH) radical, ABTS free radical and hydrogen peroxide. Also, the extract of Ikiyangyoung-Tang strongly inhibits the proliferation of MCF-7 cells in a dose ependent manner. And. it has cytotoxicity on NIH3T3 cells.
Conclusion:It can be concluded that Ikiyangyoung-Tang extract has an antioxidative effect and antiproliferative effect on MCF-7 human breast cancer cells.
