Description

A kind of method utilizing sea cucumber blanching solution to extract selenka
Technical field
The present invention relates to the technology extracting active material from Holothurian machining accessory substance, especially a kind of method utilizing sea cucumber blanching solution to extract selenka.
Background technology
After fishing for, there is the enzyme of proteolysis such as autolytic enzyme in fresh sea cucumber, being easy to skin, self-dissolving due to himself.For the ease of preserving, fresh sea cucumber will store through hot water scalding treatment aft-loaded airfoil usually.But fresh sea cucumber produces a large amount of blanching solutions in the process of hot water treatment, find after testing: containing a large amount of active materials in sea cucumber blanching solution, as selenka.And selenka is the class main active in sea cucumber, it has multiple pharmacologically active, as antitumor action, improves immunity, antimycotic, anti-neovascularization, promotion fibrinolysis, the formation of suppression embolism, antiinflammatory action (as arthritis), anti-radioactivity and suppresses AIDS virus, hepatitis B, HSV isolation etc.; Recently research finds that selenka also participates in fat metabolism, has effect of fat-reducing.
At present, utilize sea cucumber blanching solution to extract saponin(e and have bibliographical information.Such as, disclose in CN1733793A Chinese invention patent application prospectus disclosed in 15 days February in 2006 " a kind of process utilizing Holothurian machining waste liquid to prepare Sea Cucumber Glycosides ", first sea cucumber waste liquid filters by it, then filtrate alcohol settling, leave standstill, centrifugal, again centrifuged supernatant reduced pressure concentration is removed alcohol component, obtain concentrate, large pore resin absorption column is passed through with the flow velocity of 1.5 ~ 2.0BV/h, then use water with same flow velocity wash-out to remove salinity wherein, carbohydrate, the impurity components such as pigment, then the Sea Cucumber Glycosides composition on macroporous absorbent resin is attracted to 60 ~ 70% ethanol elutions, collect eluent and be evaporated to medicinal extract shape, freeze drying is Sea Cucumber Glycosides dry product.Though this process has simple to operate, with short production cycle, that production cost is low feature, but it directly utilizes macroporous absorbent resin to adsorb saponin(e in sea cucumber blanching solution, there is the deficiency that adsorption efficiency is low, absorption selectivity not by force, easily blocks up post, saponin content purity is low.
Summary of the invention
Directly utilize macroporous absorbent resin to adsorb saponin(e in sea cucumber blanching solution to have that adsorption efficiency is low to overcome in prior art, absorption selectivity not by force, easily stifled post, deficiency that saponin content purity is low, the invention provides that a kind of rational technology, operation feasible, production cost are low, efficiency of pcr product and the high sea cucumber blanching solution that utilizes of purity extract the method for selenka.
The technical solution adopted for the present invention to solve the technical problems is: a kind of method utilizing sea cucumber blanching solution to extract selenka, is characterized in that: it is through following process steps:
(1) the choosing and process of raw material
Choosing sea cucumber blanching solution is raw material, and by its reduced pressure concentration, being concentrated into solid content is 20 ~ 45%, obtains concentrate;
(2) spraying dry
By the concentrate spraying dry obtained in step (1), obtain the first pressed powder;
(3) degreasing
The first pressed powder obtained in step (2) is utilized supercritical CO 2fluid extraction, removes grease, obtains the second pressed powder;
(4) alcohol extracting
The second pressed powder obtained in step (3) is added the ethanolic solution of its quality 20 ~ 100 times, extract 12 ~ 24h, obtain extract; Wherein, the concentration of described ethanolic solution is 70 ~ 95%;
(5) suction filtration concentrates
The extract obtained in step (4) is carried out suction filtration, obtains suction filtration liquid; Filter cake is utilized again concentration be 70 ~ 95% ethanolic solution extract 12 ~ 24h, obtain filter cake alcohol extract; Repeat this step 2 time; Merge all suction filtration liquid and filter cake alcohol extract, reduced pressure concentration, remove ethanol, obtain concentrate;
(6) depositing in water
The pure water adding its volume 100 ~ 300 times in the concentrate obtained in step (5) is dissolved, removes precipitation through Horizontal helical type centrifuge, disc centrifuge, tube centrifuge successively, obtain supernatant, for subsequent use;
(7) affinity chromatography
By the supernatant that obtains in step (6) by large pore resin absorption column adsorption chromatography, utilize concentration be 60 ~ 70% ethanolic solution wash-out large pore resin absorption column, obtain eluent;
(8) concentrate drying
By the eluent vacuum freeze drying obtained in step (7), obtain selenka extract.
Described sea cucumber blanching solution is fresh sea cucumber after dissecting and removing intestines, puts into boiling water and boils 10 ~ 30min, pulls gained liquid after sea cucumber out.
Described supercritical CO 2the temperature of fluid extraction controls to be 40 ~ 50 DEG C, and pressure is 30 ~ 40Mpa, and extraction time is 1 ~ 2h.
Large pore resin absorption column is AB-8 type or D101 type.
Sea cucumber blanching solution concentrates by the present invention, and then spraying dry utilizes supercritical CO 2fluid extraction, the fluid of supercriticality has superpower solvability, is effectively stripped of the oil substances in sea cucumber blanching solution, avoids being mixed into of grease in subsequent extracted process; Sea cucumber blanching solution powder after degreasing, adopt alcohol precipitation water extraction, first utilize ethanolic solution to extract, multiple soluble in water again after extract is concentrated, adopt centrifugal method to remove the compound such as phosphatide, cerebroside in solution, reduce further again being mixed into of impurity in subsequent extracted process; Owing to have passed through the process of above-mentioned steps, the extraction solution obtained, clarity is high, improves macroporous adsorbent resin column chromatography adsorption efficiency, extends the service life of resin column, can be continuously produced, and improves the purity of object product; Extracted the selenka obtained by the method, purity is high, and total saponin content is between 90 ~ 95%.This technical method adds from Holothurian machining blanching solution, extract saponin(e operability and practicality, solve and directly utilize macroporous absorbent resin to adsorb saponin(e in sea cucumber blanching solution, adsorption efficiency is low, absorption selectivity not by force, easily stifled post, can not continuous seepage, drawback that saponin content purity is low.This extracting method rational technology, simple to operate, production cost is low, and the active material saponin(e of extraction all has higher health value, reduces the environmental pollution after the discharge of extra large blanching solution simultaneously, has Social and economic benef@widely.
