Problems solved by technology

[0002] Traditional methods for extracting physiologically active substances such as polymer polysaccharides, triterpenoids, organic germanium, alkaloids, etc. from Chinese herbal medicines can generally be divided into two categories, namely alcohol extraction and water precipitation method or water extraction and alcohol precipitation method, but Ganoderma lucidum spores If polysaccharides are extracted according to the above traditional methods, the amount of raw materials will be too large, and at the same time, because the spores of Ganoderma lucidum are too small, it will cause difficulties in the filtration process during the extraction process.
The biggest problem is that Ganoderma lucidum spores contain 30% oil and fat. When traditional water extraction is used, a large amount of oil and fat will be precipitated, which will interfere with the extraction of polysaccharides. It is difficult to avoid the residue of oil and impurities in the final product. Low yield

Embodiment 1

[0015] Add the Ganoderma lucidum spore powder to the mixture of water and gelatin or one of the additives, and add the amount so that the Ganoderma lucidum spore powder is bonded and shaped, mix well, make granules, dry naturally, and use CO 2 The supercritical extraction method removes the oily substances in it. Weigh 10kg of degreased Ganoderma lucidum spores, put them into an extraction tank, add 15 times of water, soak for 2 hours, heat to boil, keep reflux for 4 hours, centrifuge the extract, concentrate the clarified filtrate to 5kg, add 3 times the weight of 95% edible alcohol , let stand for 24 hours to make the polysaccharide precipitate, filter, and dry to obtain 122g of Ganoderma lucidum spore polysaccharide.

Embodiment 2

[0017] The operation process is the same as in Example 1, the difference is that the extraction condition is to add 20 times of water, soak for 2 hours, heat to boil, keep reflux for 4 hours, add 3 times the weight of 95% edible alcohol after concentration to precipitate polysaccharides, and dry to obtain Ganoderma lucidum Spore polysaccharide 130g.

Embodiment 3

[0019] Same as Example 2, except that the amount of water added was 4 times, and finally 102 g of Ganoderma lucidum spore polysaccharide was obtained.

Abstract

The present invention relates to a method for extracting ganoderic spore polysaccharide. It is characterized by that firstly, it uses CO2 supercritical extraction method to extract ganoderic spore oil for another application, and makes the residue obtained after the ganoderic spore oil is extracted undergo the processes of removing fat, water extraction, alcohol precipitation, filtration and drying so as to obtain the invented ganoderic spore polysaccharide.

Description

technical field [0001] The invention relates to a method for extracting physiologically active substances from Chinese medicinal materials, in particular to a method for extracting ganoderma lucidum spore polysaccharide. Background technique [0002] Traditional methods for extracting physiologically active substances such as polymer polysaccharides, triterpenoids, organic germanium, alkaloids, etc. from Chinese herbal medicines can generally be divided into two categories, namely alcohol extraction and water precipitation method or water extraction and alcohol precipitation method, but Ganoderma lucidum spores If the polysaccharide is extracted by the above-mentioned traditional method, the amount of raw materials will be too large, and at the same time, because the ganoderma spores are too small, it will cause difficulties in the filtration process in the extraction process. The biggest problem is that Ganoderma lucidum spores contain 30% oi...
