Embodiment 1

[0025] The extraction method of wolfberry polysaccharide extract comprises the following steps:

[0026] Step 1, in parts by weight, take 200 parts of dried wolfberry, add to 100 parts of petroleum ether, stir evenly, let stand for 10 minutes, filter with suction, dry the solid in a 40°C decompression drying oven for 1 hour, Obtain the first wolfberry powder;

[0027] In the second step, the first wolfberry powder is subjected to 0.5Mpa high-pressure treatment in the range of 20°C to obtain the second wolfberry powder;

[0028] Step 3, add the second wolfberry powder into distilled water, control the ratio of material to liquid to 1g / 30ml, then add 0.1% enzyme to the material liquid, carry out enzymatic hydrolysis and extraction, and the enzyme is selected from alkaline pectate cleavage The mixture of enzyme, alkaline cellulase, alkaline xylanase and laccase according to the weight ratio of 2:3:2:0.5, the temperature range of enzymolysis and extraction at 60°C, the time is 2h...

Embodiment 2

[0033] The extraction method of wolfberry polysaccharide extract comprises the following steps:

[0034] Step 1, in parts by weight, take 220 parts of dried wolfberry, add to 120 parts of petroleum ether, stir evenly, let stand for 20 minutes, filter with suction, dry the solid in a 60°C decompression drying oven for 3 hours, Obtain the first wolfberry powder;

[0035] In the second step, the first wolfberry powder is subjected to 1Mpa high-pressure treatment in the range of 40°C to obtain the second wolfberry powder;

[0036] Step 3, add the second wolfberry powder into distilled water, control the ratio of material to liquid to 1g / 35ml, and then add 0.2% enzyme to the material solution for enzymatic hydrolysis and extraction. The enzyme is selected from alkaline pectate cleavage The mixture of enzyme, alkaline cellulase, alkaline xylanase and laccase according to the weight ratio of 2:3:2:0.5, the temperature range of enzymolysis and extraction at 70°C is 4h, and it is coll...

Abstract

The invention relates to a lycium barbarum polysaccharide extract, an extraction method and application of the lycium barbarum polysaccharide extract in preparation of blood fat reducing drugs, and belongs to the technical field of natural product extraction. The purity of lycium barbarum polysaccharide is 56%-62%, and the weight-average molecular weight (Mw) range of the lycium barbarum polysaccharide is 18,000-32,000. The problems that a conventional barbary wolfberry fruit extract is low in polysaccharide activity and purity can be solved, and the lycium barbarum polysaccharide extract has a good blood fat reducing application effect.

Description

technical field [0001] The invention relates to a wolfberry polysaccharide extract, an extraction method and its application in the preparation of blood lipid-lowering drugs, and belongs to the technical field of natural product extraction. Background technique [0002] Lycium barbarum is a traditional precious Chinese medicinal material in my country, known as "Red Treasure", rich in plant polysaccharides, protein, vitamins and other nutrients. The main effect of wolfberry is to nourish the liver and kidney, benefit energy and improve eyesight; it is used for consumptive essence deficiency, sore waist and knees; vertigo and tinnitus, internal heat and thirst, blood deficiency and chlorosis, and blurred vision. Lycium barbarum polysaccharide is a water-soluble polysaccharide extracted from Lycium barbarum. It has been confirmed that this polysaccharide is a proteoglycan, with a molecular weight of 22-25 kD, and is composed of six monosaccharide components: arabinose, gluc...
