| titleOfInvention | A kind of Dendrobium chinensis polysaccharide, its preparation method and application |
| abstract | The invention discloses a polysaccharide of Dendrobium chinensis, a preparation method and application thereof. The average molecular weight of the polysaccharide is in the range of 2.56×10 3 ‑‑1.39×10 7 Da. The dried Dendrobium dendrobii is extracted with boiling water at 100°C, and then the extract is Perform microwave drying to obtain crude sugar; dissolve the crude sugar into water, suspend, extract, add Saveg reagent to the aqueous layer, mix uniformly, and shake; centrifuge to collect the supernatant. Add ethanol to the supernatant to make the final volume concentration to 90%, precipitate overnight, centrifuge, collect the precipitate, dissolve in water, and dialyze in distilled water for 72 h; add activated carbon, and heat the polysaccharide solution to 80 °C for 20 min. , cooled to 60°C, filtered to remove activated carbon residue, added absolute ethanol to the polysaccharide solution to make the final volume concentration of ethanol 90%, precipitated overnight, centrifuged, and freeze-dried to obtain Dendrobium officinale polysaccharide. The invention can prevent and treat tobacco mosaic virus disease, cucumber mosaic virus disease and potato virus Y, and the preparation method is simple. |
