Problems solved by technology

[0002] In the prior art, it is generally believed that the pharmacological activity and chemical components of Ganoderma lucidum are not as good as those of Ganoderma lucidum, especially the active ingredients of polysaccharides with medicinal value are low and have no actual extraction value. Therefore, in the prior art, only Ganoderma lucidum is extracted from Ganoderma lucidum. However, the use of grass-grown Ganoderma lucidum is rejected. The annual cultivation of Ganoderma lucidum in my country consumes more than 110,000 cubic meters of wood, which obviously has a great impact on the ecological environment, and the cost of cultivating Ganoderma lucidum is also relatively high.

Embodiment Construction

[0054] Below in conjunction with embodiment the present invention is described in detail.

[0055] best practice;

[0056] 1. Select grass-planted Ganoderma lucidum, clean, dry, crush,

[0057] After cleaning the fruiting bodies of the dried Ganoderma lucidum, dry them, and crush them into shredded tobacco-like substances of about 20 meshes with a coarse particle grinder.

[0058] 2. After reflux with ethanol and hot water extraction,

[0059] Weigh 300 grams of crushed Ganoderma lucidum,

[0060] 1) Reflux with 3000-4000 ml of 95% ethanol for 3 hours,

[0061] 2) reclaim ethanol, dry Ganoderma lucidum alcohol and filament,

[0062] 3) Ganoderma lucidum alcohol and crushed product were reflux extracted 3 times with 15 times the amount of hot water for 2.5 hours, 2 hours, and 1 hour respectively, and the filtered water extracts were combined.

[0063] 3. Concentrate the water extract,

[0064] 1) Concentrate to one tenth of the original volume at a temperature of 90°C,

...

Abstract

A herbaceous ganoderic polyose is prepared from the herbaceous ganoderma through culturing ganoderma with fungal herb to generate sporophores, washing, drying, crushing, refluxing with alcohol, extracting in hot water, concentrating, depositing in alcohol to obtain the first polyose peptide, washing respectively with alcohol, acetone and ether three times of each, centrifugal separation to removesupernatant, and low-temp drying to obtain crude polyose peptdide. Its advantages are low cost, high extracting rate and high purity.

Description

technical field [0001] The invention relates to a polysaccharide and its preparation, in particular to a herbaceous Ganoderma lucidum polysaccharide peptide and its extraction method. Background technique [0002] In the prior art, it is generally believed that the pharmacological activity and chemical components of Ganoderma lucidum are not as good as those of Ganoderma lucidum, especially the active ingredients of polysaccharides with medicinal value are low and have no actual extraction value. Therefore, in the prior art, only Ganoderma lucidum is extracted from Ganoderma lucidum. However, the use of grass-grown Ganoderma lucidum is rejected. The annual cultivation of Ganoderma lucidum in my country consumes more than 110,000 cubic meters of wood, which obviously has a great impact on the ecological environment, and the cost of cultivating Ganoderma lucidum is also relatively high. Contents of the invention [0003] The object of the present invention is to overcome the ...
