Phellinus baumii has been used in traditional oriental medicine for the treatment of various cancer types, such as lung cancer, ovarian cancer and malignant melanoma. It has strong anti-cancer, anti-inflammatory and antioxidant activities due to its polysaccharides including glucan, schizophyllan, heteroglycan and lentinan, as well as its polyphenolics such as protocatechuic acid, caffeic acid, coumaric acid. ${\beta}$-Glucan and polyphenolics may be the most important activ ecompounds in P. baumii. Therefore, researchers have focused on these two compounds to improve their contents in extracts. In this study, P. baumii was extracted with hot-water and ethanol at different pH conditions, and their ${\beta}$-glucan contents, antioxidant activity and antioxidant contents were determined. Extraction yield was highest for the 60% ethanol extract at pH 4. The ${\beta}$-glucan contents of the hot-water extract at pH 7 was higher than those of the ethanol extracts. The antioxidant contents and antioxidant activities of the ethanol extracts were higher than those of the hot-water extracts. Extraction with 60% ethanol at pH 7 was appropriate with respect to the antioxidant capacities.
