摘要
从9种蕨类植物中提取多糖,以苯酚-硫酸比色法测定其含量,并采用纸片法进行抗动植物病原菌实验。结果表明,9种蕨类多糖含量差别较大,其多糖提取物表现出不同程度的抑制动植物病原菌活性。
The crude polysaccharides were extracted from nine species of pteridophytes and their contents were determined by oxybenzene-sulfuric acid colorimentry. These crude extracts were tested for their efficiency against the plant pathogenic microorganisms and animal pathogenic bateria using the agar disc diffusion method. The results showed that there were great differences among the polysaccharides contents of nine pteridophytes and polysaccharide extracts had varying activities against different phytopathogenic microorganisms and animal pathogenic microorganisms.
