| 摘 要： | 对榆耳菌丝体多糖提取条件和脱色条件进行研究，以提高产品的得率和纯度。通过单因素及正交试验，得到榆耳菌丝体胞内多糖的最佳提取条件：水料比40:1、提取时间8h、提取温度95℃、提取次数3次。在此条件下，榆耳菌丝体胞子内多糖得率为8.60%。采用AB-8大孔树脂对多糖脱色，最佳条件为添加量0.2g/mL、pH4.0、温度60℃。

| Abstract: | Orthogonal array design was used to optimize conditions for the extraction and de-colorization of mycelial polysaccharides from Gloeostereum incarnatum to obtain enhanced yield and purity. The optimum extraction conditions were found to be three extraction cycles at 95 ℃ for 8 h with a water-to-solid ratio of 40:1. Under these conditions, the polysaccharide yield was 8.60%. AB-8 resin was used to decolorize the crude polysaccharide extract, and the optimum decolorization conditions were found to be a solid-to-liquid ratio of 0.2 g/mL, pH 4.0 and 60 ℃. |
