The purposes of this study were to investigate the effects of bamboo (SasacoreanaNakai)extracton chemical characteristics and biological activities. pH ranges of bamboo extract using ’water and ethanol were between 5.2 and 6.1. The concentration of total phenol compounds using ethanol extract was 0.51%, which was about 2.0 fold higher than that of water extract. The mineral concentrations were order of K, Mg, Ca. and Na, respectively. The nitrite scavenging ratio of bamboo extract using ethanol was 20.4% in vitro. In the case of bamboo extract using water, it was 18.0%. Especially, the maximum nitrite scavenging ratio was obtained at pH 1.5. On the other hand, when pH was increased from 3.0 to 6.0, the nitrite scavenging ratio was decreased from 16.2% to 3.0%. The antioxidant activity of bamboo extract in vitro was increased from 100 to 160% when bamboo extract using ethanol was increased from 10 to 50μL. These results suggest that the bamboo extract of Sasa coreana Nakai using ethanol can be used in bioactive and functional material.
