Abstract

This study was investigated the effect of tumor cell cytotoxicity of gamma irradiated Chaga mushroom extract (CME). CME was prepared by hot water extraction at $70^{\circ}C$ for 4 hours and lyophilized. $Ten\;mg\;ml^{-1}$ of lyophilized CME powder was dissolved with deionized water and then irradiated at the doses of 10, 50, 100, and 150kGy by cobalt 60 gamma irradiator. The gamma-irradiated and non-irradiated CME were treated into the cancer cell, including human stomach cancer and human colon cancer. Cytotoxicity against the cancer cell was increased in gamma-irradiated CME and antioxidant activity was also increased in gamma-irradiated CME, as irradiation dose increased. Therefore, it was considered that gamma irradiation was effective method for improvement of the cancer cell cytotoxicity and antioxidant activity of Chaga mushroom extract.
