| titleOfInvention | A kind of extraction and purification process of dendrobium officinale polysaccharide |
| abstract | An extraction and purification process of dendrobium polysaccharides from the roots of dendrobium candidum, comprising immersing the roots in acetic acid solution, washing and drying, then immersing in ethanol, refluxing and extracting, filtering to collect filter residues, washing and drying to obtain medicinal residues; crushing medicinal residues After extraction in a water bath, filter the extract to obtain the filtrate, add absolute ethanol to the filtrate, centrifuge to collect the precipitate after standing overnight, dissolve the dried precipitate in deionized water, then add Sevage reagent, shake, stand still and centrifuge in sequence The operation is repeated 3 to 5 times, and the collected upper layer solution is combined; activated carbon is added to the upper layer solution, stirred and then filtered, and the filtrate is concentrated under reduced pressure to obtain the dendrobium polysaccharide from the root of Dendrobium officinale. The process of the invention can not only protect the effective components of the dendrobium candidum from being damaged by heat, but also preserve the polysaccharide structure of the dendrobium to the greatest extent. |
