Extraction Process Optimization of Endo-Polysaccharides from Phellinus igniarius

2014 
Polysaccharides of Phellinus igniarius have remarkable bioactivities and attracted considerable attention. In this study, extraction process of endo-polysaccharides from P. igniariu was investigated. The extraction conditions including ratio of sporocarp to water, extraction time, extraction temperature, extraction times were optimized. The experimental results indicated that the maximal yield of endo-polysaccharides from P. igniariu was 2.93 %, and the optimal conditions were as follows: ratio of sporocarp to water 1:30, extraction time 2 h, extraction temperature 90 °C, extraction twice. The best final ethanol concentration was 80 %. In addition, protein removal rate could reach 90.6 % using trichloroacetic acid method in extracting polysaccharides process.
