Problems solved by technology

Unsaturated fatty acids with economic value such as linoleic acid and oleic acid in Schisandra chinensis are finally discarded together with the extraction residue, resulting in waste
It was found that the inhibitory effect of alcohol extract and water extract on Escherichia coli was greater than that of supercritical extract; the inhibitory effect of supercritical extract and water extract on Staphylococcus aureus was less than that of alcohol extract, indicating that supercritical extract The antibacterial effect is not ideal

Embodiment 1

[0064] Take 100Kg of dried fruit of Schisandra chinensis, add 10 times the amount (v / w) and 8 times the amount (v / w) of water respectively, soak it twice at 60°C for 2 hours each time, combine the soaking liquid, and pass it through the inorganic ceramic Membrane filtration, the filtrate is filtered with a nanofiltration membrane with a molecular weight cut-off of 2000 Daltons, the filtrate is concentrated under reduced pressure, added 2Kg of medicinal starch, mixed, and spray-dried to obtain 19Kg of brown dry powder containing Schisandra organic acid, wherein the total The content of organic acid is 43.15%.

[0065] Add 2 times the volume of water to the remaining liquid, filter it with a nanofiltration membrane with a molecular weight cut-off of 2000 Daltons, discard the filtrate, and spray dry the remaining liquid to obtain 5.9Kg of the polysaccharide part of Schisandra chinensis, which is a light brown powder. The content of total polysaccharide is 57.91%.

Embodiment 2

[0069] Put about 13.0Kg of Schisandra oil and distilled water obtained in Example 1 into a flat-bottomed flask at an oil:water ratio of 2:1.3 to 2:1.5, slowly heat up to 80 to 85°C under stirring, and slowly drop in 40% NaOH solution, so that the final pH value of the reaction solution reaches 12, stir and keep warm for 5 to 6 hours, then transfer it into a separatory funnel, let it stand to separate layers, and remove the lower layer of glycerin. Transfer the treated reaction solution into a flat-bottomed flask again, slowly raise the temperature to 90-95°C, slowly drop in 28% sulfuric acid solution to make the final pH of the reaction solution 2, keep it warm for 4-5 hours, and then transfer it into a separatory funnel. Wash with distilled water at 60-70°C until neutral, and after standing to separate layers, remove the lower water layer to obtain 12.1Kg of crude fatty acid.

Embodiment 3

[0072] Take 100Kg of dried fruit of Schisandra chinensis, add 10 times the amount (v / w) and 8 times the amount (v / w) of water to soak twice at 60°C for 2 hours each time. Membrane filtration, the filtrate is filtered with a nanofiltration membrane with a molecular weight cut-off of 2000 Daltons, the filtrate is concentrated under reduced pressure, 2Kg of medicinal starch is added to mix, and spray-dried to obtain 19.1Kg of brown dry powder containing Schisandra organic acid, wherein The content of total organic acids is 44.76%.

[0073] Add 2 times the volume of water to the remaining liquid, filter it with a nanofiltration membrane with a molecular weight cut-off of 2000 Daltons, discard the filtrate, and spray dry the remaining liquid to obtain 5.3Kg Schisandra polysaccharide, which is a light brown powder. The content of polysaccharide is 52.23%.

[0074] The soaked Schisandra chinensis (that is, Schisandra slag) was dried, crushed into coarse powder, and then subcritical ...

Abstract

The invention relates to an extraction method for comprehensive utilization of schisandrae chinensis. The method is characterized by including the steps of: (1) extraction of schisandra chinensis polysaccharide and water-soluble organic acid from fructus schisandrae chinensis; and (2) extraction of schisandrae chinensis lignans and schisandrae chinensis oil from schisandrae chinensis residue obtained by step (1).

Description

technical field [0001] The invention relates to the field of extraction of effective plant components, and more specifically relates to an extraction method for comprehensive utilization of schisandra chinensis. Background technique [0002] Schisandra chinensis (Schisandra chinensis (Turcz.) Baill.) or Schisandra sphenanthera (Schisandra sphenanthera R&d.et Wils.) is a general term for the dried mature fruit of Magnoliaceae. The ingredients in Schisandra include Schisandra volatile oil, polysaccharides, organic acids, lignans, and Schisandra oil. [0003] The volatile oil of Schisandra chinensis mainly consists of monoterpenes, oxygenated monoterpenes, sesquiterpenes and oxygenated sesquiterpenes. [0004] Schisandra polysaccharide is a polar macromolecular compound that is easily soluble in water. It is generally extracted by water extraction and alcohol precipitation. The crude polysaccharide obtained generally contains many impurities such as inorganic salts, proteins, ...
