摘要：以几种植物提取物为实验材料，研究其抗氧化性及对体外小鼠免疫细胞增殖的影响，结果表明：不同种类的植物提取物显示不同的抗氧化活性，在17种植物中以香菇水提取物和红枣无水乙醇提取物的抗氧化活性最高，它们的DPPH清除率分别为95.5%和90.0%。另外，对体外小鼠免疫细胞增殖影响最明显的植物有黑木耳、白萝卜和银耳的水提取物和无水乙醇提取物以及香菇的无水乙醇提取物，它们均在一定浓度的一定培养时间内表现出较高的细胞存活率和较低的细胞抑制率。进一步对有显著影响的植物进行比较得出白萝卜对体外小鼠免疫细胞增殖的影响最为明显。本课题可为进一步研究日常食用植物的选择和食用提供参考。43275

Study on the effects of several plant extracts on the proliferation of immune cells in vitro

Abstract：Selected several plant extracts as experimental material, this paper studied the effect of anti-oxidation and on the proliferation of mouse immune cells in vitro. The results showed that different kinds of ingredients showed different antioxidant activity. The Jujube mushroom water extract and ethanol extract showed the highest antioxidant activity among the 17 plant extracts as 95.5% and 90.0% DPPH clearance rate. In addition, water extract and ethanol extract of black fungus, white radish and tremella and extract of letinous edodes ethanol on mouse immune cells proliferation in vitro effect is the most obvious ingredients of them. They showed a higher survival rate and lower cell inhibition rate in a certain concentration and certain incubation time. The effect of white radish on the proliferation of immune cells in vitro was the most significant. It is provided reference for the further study of the choice and consumption of edible food.
