But the research work on polysaccharides of hawthorn fruit (HFP) has not been found. So in this dissertation, the author conducted a series of study on HFP, which were extracted, isolated and purified from hawthorn fruit, and their physical-chemical characteristics and chemical structure were determined with instruments analysis technique. The following results were achieved.1.The water-soluble polysaccharides of hawthorn fruit were extracted...
