摘要: 目的:研究苦荞壳提取物的抗氧化活性。方法:通过研究苦荞壳提取物对小鼠红细胞溶血性、小鼠红细胞MDA生成、肝脏自发性脂质过氧化、Fe2+-H2O2诱导的肝脏脂质过氧化、以及小鼠肝脏线粒体肿胀的影响探讨了苦荞壳提取物的抗氧化活性。结果:苦荞壳提取物显著抑制小鼠肝脏自发性脂质过氧化和Fe2+-H2O2诱导的肝脏脂质过氧化,抑制率分别达到38.1%和24.0%,并对Fe2+-VC诱导的小鼠肝线粒体肿胀具有显著的抑制作用;苦荞壳提取物不能抑制小鼠红细胞溶血,但可以抑制红细胞MDA的生成。结论:苦荞壳提取物具有抗氧化活性;

Abstract: Purpose: To study the anti-oxidation activity of tatarybuckwtheat shell extraction. Methods: The effects oftatarybuckwtheat shell extraction on hemolysis of mice red blood cell, liver lipid peroxidation, Fe2+-H2O2 induced liver lipidperoxidation and VC+Fe2+ induced mitochondria swelling were studied. Results: The concentration of MDA in liver of mice, nomatter produced by itself or induced by Fe2+-H2O2, could be reduced by tatarybuckwtheat shell extraction. The maximum inhibitionreached to 38.1% and 24.0%. And the swelling of mice liver mitochondria could also be restrained. Though tatarybuckwtheatshell extraction could not reduce hemolysis of mice red blood cell, it could reduce the concentration of MDA in blood.Conclusion: The tatarybuckwtheat shell extraction has anti-oxidant activities.
