| 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。

| Abstract: | 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 (C1A) 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%. C1A 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 strongc apability ofa ntioxidation. |
