| Abstract: | Polysaccharides in Poria cocos Wolf from different localities were extracted with urea solution and were determined by spectrophotometry at 490nm with phenol-concentrated sulfuric acid as the color developer. The content of polysaccharides in seven samples ranged from 81.9% to 88.3%. The method is simple and accurate for the quntitative determination of natural water insoluble polysaccharides. |
