摘要
通过灵芝、香菇、虫草、灰树花、羊肚菌五种不同食用菌中多糖含量的比较研究,了解了这五种食用菌多糖产品的含量。采用水提醇沉法提取多糖,苯酚-硫酸比色法测定多糖含量。结果表明,苯酚-硫酸比色法测定五种多糖产品的加样回收率平均为99.28%。该法操作简单、准确,具有较好的稳定性及重现性。灰树花多糖含量最高,虫草多糖含量最低。
Polysaccharide content of five different mushrooms was compared and the content was obtained. Water extraction and alcohol precipitation were used to extract the polysaccharide and phenol sulfuric acid method was used to determine the polysaccharide content. The experimental result showed that the average recovery rate of polysaccharides was 99.47% by sulfuric acid phenol determination. Phenol sulfuric acid determination of polysaccharide is simple, accurate, and it has good stability and reproducibility.
