Problems solved by technology

[0004] In the traditional extraction of Polygonatum Polysaccharides, the water extraction method is generally used to extract the polysaccharide nutrients in Polygonatum. However, only using the water extraction method, the yield of Polygonatum Polysaccharides is very low, and the extracted Polygonatum residue still contains A lot of Polygonatum polysaccharides, the waste is very serious
[0005] In addition, during the extraction process, the Polygonatum powder is generally placed in a container containing a solvent, and then placed in an ultrasonic extraction device for ultrasonic extraction, so that Polygonatum polysaccharides are precipitated. However, the existing ultrasonic extraction device generally does not have a stirring device and is located in the middle of the container. The extraction effect of Polygonatum granules in the part is poor, which is not conducive to the complete precipitation of Polygonatum polysaccharides inside the Polygonatum granules

Abstract

The invention discloses a method for extracting Polygonatum extract, which comprises the following steps: (1) grinding the washed and dried rhizome of Polygonatum into powder, passing through a 70-80 mesh sieve to obtain Polygonatum powder; Extract with pure water at 90°C-100°C for 60-80min, filter, concentrate the filtrate to obtain concentrate A and filter residue A; (3) dry the filter residue A at 40-50°C to obtain filter residue B; (4 ) in the filter residue B, adding an ethanol solution with a volume ratio of 5:1 to the filter residue B, the mass concentration of the ethanol solution is 80% to 95%, leaching for 20 to 30min, filtering, and concentrating the filtrate to obtain a concentrated solution B ; (5) Concentrate A and concentrate B are combined and concentrated to an extract. The invention has the advantages of simple operation and high yield of polygonatum polysaccharide.

Description

technical field [0001] The invention relates to the field of extracting active ingredients in Polygonatum, in particular to an extraction method and device for extracting Polygonatum extract and animal feed with anti-virus and growth-promoting effects. Background technique [0002] Polygonatum is sweet in nature, refreshing to eat, and its fleshy rhizome is thick, containing a lot of starch, sugar, fat, protein, carotene, vitamins and various other nutrients. Polygonatum can be eaten raw or stewed. Long-term consumption can double your strength, fill your muscles, and strengthen your bone marrow, which is very beneficial to your body. [0003] Among them, Rhizoma Polygonatum contains multiple active ingredients, for example Polygonatum polysaccharide is one of the important active ingredients. Polygonatum polysaccharide has the advantages of lowering blood sugar, clearing away heat and detoxification, and strengthening the body. Therefore, how to extract Polygonatum polysa...
