Abstract: In this study,polysaccharides were extracted from the seed of Camellia oleifera Abel by water extraction and alcohol precipitation.High performance ion chromatographic analysis showed the polysaccharides mainly composed of glucose,galactose and arabinose.Meanwhile,the amino acid composition analysis result showed that there were 17 amino acids including glutamic acid,arginine and aspanic acid.The antioxidant activity analysis results indicated that the IC50 values of polysaccharides against ·OH,H2O2 and DPPH· were 5.47,4.03 and 0.54 mg/mL,respectively.In case of protective effect on oxidative DNA damage,the results showed that polysaccharides had an effect with various levels of oxidative DNA damage induced by ·OH and H2O2.
