Description
Technical field
The present invention relates to the technical field of seeweed polyphenol, particularly relate to a kind of preparation method of high-purity seeweed polyphenol.
Background technology
Sargassum is the main source of sea-plant polyphenol, and its structure and Lu Yuan plant polyphenol exist a great difference: Lu Yuan plant polyphenol is derived by gallic acid and flower acid of mixing; Seeweed polyphenol is then the derivant of phloroglucinol.Research display, seeweed polyphenol at antioxidation, improve in metabolic syndrome, control degenerative disease etc. and have specially good effect, and safety non-toxic.Therefore, American-European countries drops into the Application and Development that huge fund implements seeweed polyphenol in succession.High-purity seeweed polyphenol has the advantages such as biological activity is strong, medical value is high, good stability, is the product of biomedicine field urgent needs.
But because seeweed polyphenol is present in the algae bubble of alginic cell inside, embedded by algin, cellulose even depth, conventional extraction techniques is difficult to obtain high yield, and production cost is high, and purity is lower.Such as, Chinese invention patent application CN102579508A " a kind of preparation method of Sargassum fusiforme (Harv.) Setch brown algae polyphenols ", open is raw material with Sargassum fusiforme (Harv.) Setch, adopts methanol heating extraction (40 DEG C), then adopts different solvents extraction and ultrafiltration to retain means and prepares brown algae polyphenols; Chinese invention patent application CN102397300A " a kind of extracting method of brown algae polyphenols ", disclose with Fresh Laminaria Japonica, sargassum thunbergii, Thallus Sargassi Kjellmaniani as raw material, the solvent extraction of employing machine, purification by macroporous resin prepare 3 kinds of brown algae polyphenols, and its productive rate is respectively 0.3 ‰, 2.5 ‰, 3 ‰; Chinese invention patent application CN103610704A " a kind of extracting method of brown algae polyphenols ", open with fresh Sargassum Brown algae or Thallus Laminariae (Thallus Eckloniae) for raw material, organic solvent lixiviate in hot bath is adopted after broken, after purification by macroporous resin, eluting, concentrated, lyophilization, obtain brown algae polyphenols extract, productive rate is 2.5 ‰; Chinese invention patent application CN104382951A " a kind of extracting method of seeweed polyphenol ", disclose with Chlorella pyrenoidesa, Euglena, salt alga three kinds of algae as raw material, take ethanol as solvent, adopt microwave combined extractive technique, after extracting liquid filtering, obtain the polyphenol extract of 3 kinds of Sargassums through lyophilization; Chinese invention patent mandate CN102935093B " a kind of extracting method of seeweed polyphenol ", discloses with 40 object Sargassum powder for raw material, adopts microwave-assisted water extraction to extract, then obtains the polyphenol extract of purity about 75% through purification by macroporous resin; Chinese invention patent mandate CN102166230B " method of microwave-assisted seeweed polyphenol ", open is raw material with Sargassum powder, with alcohol-acetone-water mixed solvent, extracts seeweed polyphenol in conjunction with microwave technology, after filtration, lyophilization obtains seeweed polyphenol crude extract, and extraction ratio can reach 2.26%.The above-mentioned method preparing seeweed polyphenol lacks the comprehensive utilization to main components such as Algins, serious waste of resources; Also there is following problem in the above-mentioned Technology preparing seeweed polyphenol simultaneously: 1) inferior separating effect, purity is low.Seeweed polyphenol easily and alginate jelly, albumen form complex with the form of non-covalent bond, be difficult to be isolated in follow-up purge process, cause the response rate of seeweed polyphenol low; In addition, also containing a large amount of fat-soluble pigment in the seeweed polyphenol of extraction, conventional post chromatographic technique cannot realize effective separation, causes the purity of product low.2) structural deterioration is large, active low.Seeweed polyphenol extremely unstable, oxidizable, the high temperature in the course of processing, alkaline ph values, oxygen etc. all can destroy its biological activity.Although microwave technology, ultrasound-assisted extraction technology can improve the yield of Sargassum ocean polyphenol, leaching process can produce high temperature, adds shortage effective protection measure, accelerates the oxidation of ocean polyphenol under the effect of the oxygen, causes loss of activity.3) complex manufacturing, cost is high.At present comprise pulverizing, extraction, centrifugal, filtration, upper prop, eluting, resin regeneration, the repeatedly multiple working procedure such as concentrated, dry for the technique of processing seeweed polyphenol; Conventional column chromatography purification seeweed polyphenol also must be equipped with the equipment such as constant flow pump, glass column, gathering-device, and cause the production time long, equipment requirements is high, limits industrialized development.This is the key technology bottleneck causing seeweed polyphenol commercial application.
