To show the anti-oxidation effects of Phragmitis rhizoma extract, this study investigated the composition ratio of its components, thecontent of the anti-oxidative materials polyphenol and flavonoid, and the DPPH scavenging effect and SOD activity to measure anti-oxidative activity. It was shown that P. rhizoma is composed of the following: 77.88% natural fiber, 9.15% moisture, 6.62% protein, 5.95% minerals ash, and 0.40% natural fat.
