Embodiment 1
[0026] Example 1: 1 kg of Schisandra root was soaked in 8L of water at 60°C for 12 hours, the water was released, the root of Schisandra was taken out and dried, and the dried root of Schisandra was extracted twice with 6L of 90% ethanol, 5L of reflux, and the ethanol extracts were combined ; Filtrate, concentrate the medicinal material and the extract ratio is 1.5L, add water to 3L to disperse the ethanol concentrate, carry out steam distillation, accept the steam distillate at 1 times the weight of the medicinal material, continue to concentrate to 1L, leave the extract overnight, separate In the lower water layer, add 0.3L of 90% ethanol to the above extract and then concentrate to obtain 115g of Schisandra chinensis root ethanol extract.
[0027] 115 g of the above-mentioned Schisandra chinensis root ethanol extract was put on the column with 500 g of macroporous adsorption resin, washed with water until colorless, eluted with 50% ethanol for two column volumes, then eluted...
Embodiment 2
[0028] Example 2: 100 g of the rhizome xylem of Schisandra chinensis, soaked in 800ml, 95% ethanol for 12 hours, reflux extraction for 2 hours, then reflux extraction with 600ml of 95% ethanol for 1.5 hours, combined ethanol extract; filtered, concentrated to obtain ethanol from the rhizome of Schisandra chinensis Extract 10.5g. The ethanol extract of the rhizome xylem of Schisandra chinensis is refined with macroporous adsorption resin, take 30g of macroporous adsorption resin, first wash with water until colorless, then wash with 300ml of 60% ethanol, and finally elute with 400ml of 95% ethanol, collect 95% ethanol to wash Deliquoring, recovering ethanol under reduced pressure to obtain 3.25 g ethanol extract of Schisandra rhizome xylem, containing 18% (mass percentage) schisandrin A. The determination of the content is to use Schisandra Methanol as the reference substance, and to measure it by high performance liquid chromatography. The chromatographic conditions are: chrom...
example 3
[0029] Example 3 The hangover experiment of the extract of Schisandra chinensis. The application of the Schisandra chinensis extract of the present invention in hangover protection and liver protection is proved by the following experiment (the effect of Schisandra schisandra root and xylem rhizome extract on the whole blood ethanol content of mice).
[0030] Materials and Methods
[0031] 1.1 Experimental materials
[0032] 1.1.1 Experimental samples and reagents were provided by the Animal Room of Yanbian University School of Medicine. Schisandra chinensis root ethanol extract and Schisandra rhizome xylem ethanol extract homemade. Liquor used in the experiment: Erguotou liquor, alcohol content 50% (v / v). Bought in a supermarket, use an alcohol meter to measure its alcohol content (unchecked). Ethanol standard solution: make 0.02mg / ml with distilled water
[0033] 1.1.2 Experimental animals: Kunming mice, half male and half male, weighing 8-22g.
[0034] 1.1.3 Experime...
