| Abstract: | The total oxidation resistance of ethanol extracts were determined from shoots and shells of Phyllostachys pubescens, Phyllostachys praecox and Deltdrocalamus latiflorus. The elimination of DPPH·、OH· and O2^- · were determined through spectrophotometry, phenanthroline spectrophotometry and pyrogallol autoxidation. The comparative reducing power was determined by Prussian blue reaction, and the total oxidation resistance was based on FRAP assay. The results showed that the content of crude extracts was positively related with the elimination of DPPH · , the elimination of OH · , the elimination of O2^-, comparative reducing power and total oxidation resistance. The results of antioxidant activity of crude extracts showed that PhyUostachys pubescens was the best among three kinds of bamboos, and Phyllostachys praecox was better than Dendrocalamtts latiflorus. In comparision to the winter, the antioxidant activity of Phyllostachys pubescens was better in the spring than those in th winter. |
