Embodiment 1

[0031] Take 5 kg of jellyfish, dry and crush, add food ethanol to make the volume ratio concentration 40%, soak, reflux under reduced pressure at 60°C for 2 hours, repeat the reflux twice, filter to obtain the soaking solution, and concentrate under reduced pressure Add ethanol to the concentrated solution until the volume ratio of ethanol is 70%, centrifuge to remove the precipitate, take the supernatant, and use the cation exchange and anion exchange to remove the salt and protein respectively; the ion exchange column after desalination and protein removal Add ethanol to the eluent until the volume ratio concentration of ethanol is 90%, and dust precipitates, and the precipitate is washed three times with absolute ethanol; after the precipitate is dissolved in water, polysaccharides with a molecular weight of 400 to 80,000 Daltons are cut off with ion exchange resin , and then dried under reduced pressure at 85° C., and pulverized the dried product to obtain tan jellyfish pol...

Embodiment 2

[0033] Take 10 kg of sea punts, dry and crush, add medicinal acetone to make the volume ratio concentration 60%, soak, reflux under reduced pressure at 60°C for 2 hours, repeat the reflux twice, filter to obtain the soaking solution, and concentrate under reduced pressure Add ethanol to the concentrated solution until the concentration of ethanol volume ratio is 50%, centrifuge to remove the precipitate, take the supernatant, and use cation exchange and anion exchange to remove salt and protein respectively; the ion exchange column after desalination and protein removal Add ethanol to the eluent until the ethanol volume ratio concentration is 80% to produce dust precipitation, take the precipitate and wash it with absolute ethanol three times; after the precipitate is dissolved in water, use ion exchange resin to intercept polysaccharides with a molecular weight of 400-80000 Daltons , and then dried under reduced pressure at 85° C., and pulverized the dried product to obtain ta...

Embodiment 3

[0035] Take 10 kg of sea puckery, dry and crush, add methanol to make the volume ratio concentration 70%, soak, reflux under reduced pressure at 50°C for 2 hours, repeat the reflux twice, filter to obtain the soaking solution, concentrate under reduced pressure; concentrate Add ethanol to the ethanol volume ratio concentration to 30%, centrifuge to remove the precipitate, take the supernatant, and use the cation exchange and anion exchange to remove the salt and protein respectively; the ion exchange column is eluted after desalting and protein removal Add ethanol to the solution until the ethanol volume ratio concentration is 90% to produce a precipitate, take the precipitate and wash it three times with absolute ethanol; after the precipitate is dissolved in water, use an ion exchange resin to cut off polysaccharides with a molecular weight of 400 to 80,000 Daltons, and then in Drying under reduced pressure at 85°C, pulverizing the dried product to obtain the tan jellyfish po...

Abstract

A Sargassum pallidum polyose used for preparing medicine or health-care food with calming, sedative and hypnotic functions is prepared from Sargassum pallidum. Its preparing process is also disclosed.

Description

technical field [0001] The invention relates to a jellyfish polysaccharide extracted from jellyfish raw materials, a preparation method and application thereof. Background technique [0002] Sargassum pallidum (Turn.) C.Ag. is widely grown in the Yellow Sea and East China Sea in my country. It contains alginic acid, crude protein, and mannitol. , iodine, potassium, etc., traditional Chinese medicine uses sea poles for softening firmness and dispelling stagnation. After testing, it can correct hypothyroidism caused by iodine deficiency; in addition, it has anticoagulant, blood fat-lowering, and blood-pressure-lowering effects. Clinical use: goiter, cervical lymphatic tuberculosis, orchitis, etc. The pharmacology and extraction process of the medicinal active ingredients in the raw material of sea pufferfish have not been reported yet. Contents of the invention [0003] The object of the present invention is to propose a new substance and preparation method of the medicinal...
