| Abstract: | The amount of extractives, total flavones, polysaccharides from 23 species of cluster-bamboo′s leaf and their scavenging ability of DPPH free radical were determined. After hierarchical cluster analysis, 23 species of cluster-bamboo were fallen into 5 clusters. There are 5 species were belonged to the 4th cluster. The amount of flavones and polysaccharides in the extractives from the 5 species were higher than the others, and so as the IC_(50) value. The 5 species cluster-bamboo are good resource for extracting flavones, and the refining bamboo flavones was obtained. |
