Objection To investigate the main influencing factors for extracting total polysaccharides and two active adjuvant components from Poria cocos. Methods Extracting temperature was designed between 20℃-100℃,ratio of material/water was 1/5-1/20 (W/V),extracting time was 1-6 h,extracting frequency was 1-3 times,material size was crude slices~50 mesh,and extracting mode was standing or stirring. The sugar content was determined by phenol-sulfuric acid method and the reletive molecular mass of polysaccharides was determined with gel filtration chro...
