Preliminary Study on Extraction technology for Ganoderma Lucidum Polysaccharides of different area,different varieties

Using phenol-sulphuric acid method to detect the contents of polysaccharides,the optimum extraction conditions with water of polysaccharides from Ganoderma Lucidum were determined by single-factor test and orthogonal test.The results show that the optimum temperature of extracting was 100℃,the optimum extracting time was 2.0h and water Ganoderma Lucidum was 15: 1.The main influencing factor was temperature,next is extracting time and water Ganoderma Lucidum.The variaties of the higher extraction rate from Ganoderma Lucidum were xinzhou.The area of the higher extraction rate from Ganoderma Lucidum were Changbaishan Jilin.
