摘要
考察了亚临界水提取灵芝多糖的最佳试验条件。通过单因素和正交试验,优选出最佳提取条件为:亚临界水温度150℃,料液比(g/m L)1∶12,浸提时间为5 min,提取压力5 MPa。此工艺条件下灵芝多糖的得率可达2.15%。与传统的热水浸提法比较,亚临界水提法可明显缩短提取时间和降低成本,且得率更高。
Ganoderma lucidum polysaccharide as a non-specific immune stimulating agent is one of the most effective components of Ganoderma lucidum and has a variety of physiological and pharmacological functions,such as scavenging free radicals,anti-aging,anti-tumor and enhancing the body＇s immunity. The present study was to examine the optimal subcritical water extraction conditions of Ganoderma lucidum polysaccharide by single factor and orthogonal experiment. The results showed that the optimum extraction conditions were as follows： the temperature of subcritical water of 150 ℃,the ratio of solvent to material of 1 ∶12 g/m L,the extraction time and pressure of 5 min and 5 MPa. Under these conditions,the yield of Ganoderma lucidum polysaccharide was2.15%. Compared with the traditional hot water extraction method,the subcritical water extraction could shorten the extraction time,reduce the cost and improve the extraction yield.
