| titleOfInvention | Method for extracting atractylodes macrocephala polysaccharide |
| abstract | The invention discloses an extraction method of bighead atractylodes rhizome polysaccharide, which comprises the following steps: (1) taking powder of dry rhizoma atractylodis macrocephalae roots or/and stems, adding distilled water with the temperature of more than 85 ℃ for extraction to obtain an extract, and then adjusting the temperature of the extract to 30-80 ℃; (2) adding distilled water into the leaching liquor obtained in the step (1), adding a sulfate solution, adjusting the pH value to 3-8, reacting for 0.5-3.0h, and filtering to obtain a first extracting solution and filter residues; (3) and (3) repeatedly extracting the obtained filter residue at least once according to the steps (1) and (2) to obtain multiple extracting solutions, combining the multiple extracting solutions, evaporating and concentrating, adding absolute ethyl alcohol, standing overnight, filtering to obtain a precipitate, washing and drying the precipitate to obtain a crude product of the atractylenovata polysaccharide chelated with metal ions. The extraction method has the advantages of low process difficulty, milder extraction conditions, higher yield and better maintenance of the biological activity of the polysaccharide. |
