The invention discloses a method for extracting astragalus polysaccharide and modifying molecular, pertaining to the technical field of preparation and structure reform of Chinese medicine polysaccharides. A chlorosulfonic acid-pyridine method is used for modifying sulfating molecular, amount of products and substituting degree of sulfate radical are used as indicators, and reaction temperature, reagent mixture ratio and reaction time serve as factors. An orthogonal test is used for determining a preferential best condition of astragalus polysaccharides chlorosulfonic acid-pyridine method that the reaction temperature is 95 DEG C, the mixture ratio of chlorosulfonic acid and pyridine is 1:6 and the reaction time is 1h. Astragalus decoction is slowly added into ethanol for the first time till the final concentration is up to 50 percent, and sediment is removed; supernatant fluid is added into the ethanol till the final concentration is up 60 percent and sediment is taken to obtain crude polysaccharide. After purification, the astragalus polysaccharide is modified by an optimized condition. Through a series of comparisons between antivirus and strengthening immunocompetence, the astragalus polysaccharide has the strongest antivirus and strengthening immunocompetence by purification and sulfating modification.
