Problems solved by technology

[0017] The traditional process of polysaccharides has always been the production process of water extraction and alcohol precipitation, the cost is high, the extracted polysaccharides are dark in color, and the content of the active ingredient galacturonic acid is low, and the extracts other than polysaccharides are discarded, causing great harm. waste

Embodiment 1

[0032] 1. Add 80% ethanol with a weight concentration of 8 times the weight of the crude drug to the ginseng crude drug, extract at 70° C. for 3 hours, and centrifugally filter to obtain filtrate and residue.

[0033] 2. Concentrate the filtrate to a relative density of 1.12 at 80° C., and vacuum-dry to obtain a ginseng extract, wherein the ginsenoside content is above 30%.

[0034] 3. Add water 15 times the weight of the slag, extract at 95°C for 3 hours, concentrate the filtrate to a relative density of 1.28 at 80°C after centrifugal filtration, and use 95% ethanol by weight to adjust the alcohol to 90%. Sink for 12 hours, extract the supernatant and recover ethanol; add water to dissolve the precipitate, then use 95% ethanol by weight to adjust the alcohol content of the solution to 90%, alcohol sink for 12 hours, extract the supernatant and recover ethanol, and combine twice The extracted supernatant is filtered with diatomaceous earth, dissolved and diluted to a relative ...

Embodiment 2

[0036] 1. Add 85% ethanol with a weight concentration of 8 times the weight of the crude drug to the ginseng crude drug, extract at 80° C. for 3.5 hours, and centrifugally filter to obtain filtrate and residue.

[0037] 2. Concentrate the filtrate to a relative density of 1.12 at 80° C., and vacuum-dry to obtain a ginseng extract, wherein the ginsenoside content is above 30%.

[0038]3. Add water 15 times the weight of the slag, extract at 100°C for 3-4 hours, concentrate the filtrate to a relative density of 1.30 at 80°C after centrifugal filtration, and use ethanol with a weight concentration of 95% to adjust the alcohol content of the liquid to 90%. , alcohol precipitation for 12 hours, extract the supernatant and reclaim ethanol; add water to dissolve the precipitate, then use 95% ethanol to adjust the alcohol content of the solution to 90%, alcohol precipitation for 12 hours, extract the supernatant and reclaim ethanol, combine The supernatant extracted twice is filtered ...

Abstract

The ginseng extracting process capable of separating ginseng polyse from ginseng extract includes the following steps:1. extracting ginseng with 50-85 % concentration alcohol solution to obtain filtrate and filter residue; 2. vacuum drying filtrate to obtain ginseng extract; and 3. extracting the filter residue with water and spraying the water extract to obtain ginseng polyse. The ginseng extracting process has alcohol extraction, water extraction and alcohol precipitation combined organically to produce light brown polyse with effective component galacturonic acid content of 13-30 %, 10 % higher that of traditional process, and best utilization of the side product to obtain ginseng extract.

Description

technical field [0001] The invention relates to a ginseng extraction method for separating ginseng polysaccharides from extracts and the application of ginseng polysaccharides. Background technique [0002] Ginseng, as a precious traditional Chinese medicinal material, can nourish vital energy, solidify body fluid, and soothe the nerves. It has been used clinically as early as ancient times. In "Shen Nong's Materia Medica", ginseng is listed as the top grade, saying: "Mainly nourish the five internal organs, calm the spirit, stop panic, eliminate evil spirits, improve eyesight, and improve intelligence." [0003] Ginseng contains a variety of sugars, including monosaccharides, oligosaccharides and polysaccharides. These polysaccharides are composed of ginseng starch and ginseng pectin, and the pharmacologically active part is mainly ginseng pectin. The ginseng polysaccharide extracted from ginseng root is 80% ginseng starch, and the ginseng pectin after destarching by amyl...
