This invention relates to a field of pharmaceutical chemistry, relates to a process of extracting high water soluble polysaccharides from higher plants or fungi. The present invention discloses a process of extracting higher plants and fungi polysaccharides based on a microwave chemistry method, comprising: putting the residue or pulverized higher plants and fungi after being degreased by an organic solvent into a microwave reaction chamber to react with an acid solution; and then distilling to remove excess acid or washing with organic solvent to remove the acid; adding water solution for extraction, subjecting the extracting solution after concentration to alcohol precipitation, separating precipitates aka polysaccharides therefrom. The present invention has significant advantages like fast processing rate, high polysaccharides yield, low organic acid consumption and efficient and easy to recycle, low water consumption, low power consumption, etc., and obtained polysaccharides have high yield and purity, good water solubility, and good biological activity. |
