Bamboo is a valuable plant and has been used for many applications during several centuries. Among many parts of bamboo tree, bamboo leaves are known to have strong antioxidant, antimicrobial and anti-inflammatory activities. In this study, in vitro antioxidant activities of four domestic bamboo trees were analyzed as well as antioxidant components such as polyphenols by HPLC/MS method. Methanolic extracts were prepared from 4 species of Korean bamboo (Phyllostachys bambusoides Sieb. Et Zucc., P. nigra var. henonis Stapf, P. pubescens and Sasa coreana) resulting in average extraction yield was 18%. Using the extracts prepared before, several antioxidant activity assay including ABTS radical scavenging, DPPH radical scavenging and hydroxyl radical scavenging were examined. Ascorbic acid was used as a standard. Several polyphenols were identified based on the database of LC/MS used in this study. In addition to that, in vivo antioxidant assay using zebra fishes is under way.
