| titleOfInvention | A kind of preparation method of pachyman sulfuric acid ester |
| abstract | The present invention relates to a kind of preparation method of pachyman sulfuric acid ester, it is characterised in that comprise the following steps：Weigh 100g Poria cocos powders, it is dissolved in points for 3 times and is total up in 10 times of 0.5mol/LNaoH of volume, every time 4 DEG C of extraction polysaccharide 8h, merges 3 extraction supernatants, 10% acetic acid is neutralized to pH6~7, precipitates overnight in 4 DEG C of refrigerators, in 4 DEG C of environment, 5000g centrifugation 20min, collects precipitation, deionized water washing precipitation 3 times, washed successively 3 times with absolute ethyl alcohol, acetone and ether, in 70 DEG C of dry white pachymarans, smashed stand-by；Pachyman sulfuric acid ester sulfonation efficiency high prepared by the method for the invention, molecular weight is small, and low production cost, environmental pollution are small. |
