Embodiment 1

[0025] A high-speed shear emulsification-ionic liquid synergistically extracting ginseng polysaccharide process, comprising the following steps:

[0026] (1) Take an appropriate amount of ginseng, heat it in an oven at 80°C for 6 hours, crush it with a traditional Chinese medicine grinder, and then sieve it through a 100-mesh sieve to obtain ginseng powder, which is degreased twice with n-hexane. The mass-volume ratio of ginseng powder and n-hexane is 1 :5, each 1h, filter to obtain residue, dry;

[0027] (2) Get the ginseng powder 1g that step (1) obtains, add the 1-butyl-3-methylimidazole hexafluorophosphate aqueous solution that mass fraction is 6%, ginseng powder and 1-butyl-3-methylimidazole The solid-to-liquid ratio of the hexafluorophosphate aqueous solution is 1:40, heated to 80°C for 60 minutes of leaching; sheared for 4 minutes with a high-speed shear dispersing emulsifier to obtain a mixed solution, the gear of the high-speed shear dispersing emulsifier is set to E,...

Embodiment 2

[0062] The difference between this example and Example 1 is that the mass fraction of step (2) ionic liquid is 10%, the solid-liquid ratio of ginseng powder and 1-butyl-3-methylimidazolium hexafluorophosphate aqueous solution is 1:80, Step (3) High-speed shearing for 10 minutes.

[0063] The content of polysaccharide in the crude extract of ginseng polysaccharide obtained by drying is 78.52%, and the yield is 25.20%.

Embodiment 3

[0065] A high-speed shear emulsification-ionic liquid synergistically extracting ginseng polysaccharide process, comprising the following steps:

[0066] (1) Take an appropriate amount of ginseng, heat it in an oven at 80°C for 6 hours, crush it with a traditional Chinese medicine grinder, and sieve it through a 60-mesh sieve to obtain ginseng powder. Use n-hexane to reflux and degrease twice. The mass-volume ratio of ginseng powder and n-hexane is 1 :5, each 1h, filter to obtain residue, dry;

[0067] (2) Get the ginseng powder 1g that step (1) obtains, add the 1-butyl-3-methylimidazole hexafluorophosphate aqueous solution that mass fraction is 2%, ginseng powder and 1-butyl-3-methylimidazole The solid-liquid ratio of the hexafluorophosphate aqueous solution is 1:120, heated to 50°C for leaching for 50 minutes; cut for 1 minute with a high-speed shear dispersing emulsifier to obtain a mixed solution, and the gear of the high-speed shear dispersing emulsifier is set to A, and ...

Abstract

The invention discloses a process for high-speed shearing emulsification-ionic liquid synergistic extraction of ginseng polysaccharide. The process for high-speed shearing emulsification-ionic liquidsynergistic extraction of ginseng polysaccharide comprises the following steps: adding an organic solvent into crushed ginseng powder, degreasing, and filtering to obtain residues; adding an aqueous solution containing an ionic liquid into the residues, heating, leaching, and shearing by using a high-shear emulsifying dispersion machine to obtain a mixed solution; carrying out centrifugal treatment on the mixed solution to obtain a supernatant liquid; and concentrating the supernatant liquid under reduced pressure to obtain an extract, adding an ethanol solution into the extract for alcohol precipitation to obtain a precipitate, and washing and drying the precipitate to obtain a ginseng polysaccharide crude extract. The method provided by the invention can effectively improve the dissolution rate of ginseng polysaccharide, and has the advantages of short extraction time, appropriate conditions and high yield.

Description

technical field [0001] The invention relates to the technical field of natural product extraction, in particular to a high-speed shear emulsification-ionic liquid collaborative extraction process for ginseng polysaccharides. Background technique [0002] According to the 2015 edition of "Chinese Pharmacopoeia", ginseng is the dried root and rhizome of Panax ginseng C.A.Mey, a plant of the genus Panax in the Araliaceae family. "Shen Nong's Materia Medica" has long recorded that "Ginseng is sweet and slightly cold. It mainly nourishes the five internal organs, soothes the spirit, calms the soul, relieves palpitations, eliminates evil spirits, improves eyesight, and improves intelligence. Take it for a long time to lighten the body and prolong life." [0003] Modern medical research shows that ginseng polysaccharides are one of the main pharmacological active ingredients in ginseng, which have pharmacological effects such as protecting the heart, anti-tumor, anti-oxidation, and...
