摘要
目的:研究决明子水溶性多糖的体外抗氧化能力。方法:采用从决明子中提取的已纯化的水溶性多糖(C1A),通过抵抗H2O2诱导红细胞氧化溶血和抵抗诱导血清过氧化产物丙二醛(MDA)的产生来评价决明子多糖的体外抗氧化能力。结果:C1A对H2O2诱导引起的红细胞溶血有较明显的抑制作用,多糖浓度达40.00%时抑制率可达45.31%;C1A并能有效地抑制血清过氧化物丙二醛(MDA)的产生,多糖浓度达15.80%时抑制率可达50.00%。结论:决明子水溶性多糖具有较明显的体外抗氧化能力。
Objective： To investigate the antioxidation capability of the water-soluble polysaccharide in vitro isolated from Semen Cassia Tora. Methods： The inhibitory effects of the purified water-soluble polysaccharides （CIA） on hemolysis of rat red blood cell induced by H2O2 and on production of rat blood serum malondialdehyde （MDA） were used to evaluate its antioxidation capability. Results： C1A decreased the hemolysis of rat red blood cell induced by H2O2, as the inhibitory rate is up to 45.31% with the concentration of 40.00%. CIA also decreases the output of blood serum malondialdehyde （MDA） and the inhibitory rate is up to 50.00% with concentration of 15.80%. Conclusion： the water-soluble polysaccharide of Semen Cassia Tora possess a strong capability of antioxidation.
