Claim Text:
1. A process of extracting higher plants or fungi polysaccharides based on a microwave chemistry treatment, comprising the following steps: a) treating pulverized higher plants or fungi with an organic solvent to remove liposoluble components thereof, to obtain higher plants or fungi residue; or directly using pulverized higher plants or fungi; b) putting the residue or pulverized higher plants or fungi obtained in the step a) into a microwave reaction chamber, adding an acid solution of a mass concentration of 5% to 99% to the reaction chamber, subjecting a mixture of the residue or pulverized higher plants or fungi and the acid solution for 5 to 120 minutes to a microwave power of mass power density of 1 kilowatt per kilogram of material to 10 kilowatts per kilogram of material under a work pressure of 20 mmHg to 760 mmHg; and then washing with an organic solvent to remove excess acid; and c) conducting extraction by adding water solution of 5 to 15 times by volume into the product obtained from the step b), subjecting the extraction solution to alcohol precipitation to form precipitates, separating the precipitates containing the polysaccharides.
