| titleOfInvention | Method for extracting artemisia vulgaris polysaccharide with high selectivity |
| abstract | The invention discloses a method for extracting Artemisia polysaccharide with high selectivity, which comprises the following steps of firstly), drying the Artemisia raw material, then crushing the mixture into folium artemisiae argyi powder, putting the folium artemisiae argyi powder in the step two) into a closed extraction tank, vacuumizing the extraction tank to 100 kPa, injecting distilled water as an extraction solvent, adding ionic liquid entrainer [ C4mim ] Cl for extraction, extracting, controlling the extraction temperature by an automatic controller, taking heat from a far infrared generator arranged at the bottom of the extraction tank, step three) pumping the liquid solvent into an evaporation tank, subjecting the liquid solvent in the evaporation tank to constant temperature and reduced pressure desolventizing treatment to obtain crude extract, dissolving with 95% ethanol solution, placing in a refrigerator at 4 deg.C to completely precipitate polysaccharide, filtering, freeze drying, the obtained Artemisia polysaccharide is an extraction method which has simple process, low investment and high efficiency and can be used for industrialized production of high-quality Artemisia polysaccharide. |
