Description
Technical field
The present invention relates to a kind of extracting method of effective ingredients in plant, more particularly to one kind extracts activity from seabuckthorn fruit peel
The method of composition ursolic acid.
Background technology
Sea-buckthorn is a kind of machaka for being born in 800~3500 meters of height above sea level or arbor, belongs to Elaeangnaceae.For integration of drinking and medicinal herbs is planted
Thing, Leaves of Hippophae L, really containing abundant nutriment and bioactivator, in recent years, with the continuous increasing of people's health care consciousness
By force, the research and development of the health product based on sea-buckthorn is also gradually taken seriously, the sea-buckthorn class product for occurring in the market
There are sea-buckthorn young tea leaves, Seabuckthorn Oil, sea-buchthorn juice beverage etc., species is various.Because sea-buckthorn is mostly wild, resource is relatively deficient, and sea-buckthorn has
Effect position and composition rationally using particularly important.
Current China's Seabuckthorn Enterprise in producing sea-buckthorn juice seabuckthorn seeds, sea-buckthorn pulp can make full use of and seabuckthorn fruit peel is big
Part but goes out of use.According to analysis seabuckthorn fruit peel contain vitamin C than Hippophae Rhamnoides L. juice more horn of plenty, vitamin E, carrotene with
And composition the effects such as biological flavone, protein and dietary fiber, its comprehensive utilization value has a high potential.
Ursolic acid has the various biological effects, bear such as calmness, anti-inflammatory, antibacterial, anti-diabetic, antiulcer, reduction blood sugar
Tartaric acid also has obvious anti-oxidation function, thus is widely used as medicine and cosmetic material.
In seabuckthorn fruit peel study of active components, useful seabuckthorn fruit peel extracts the report of ursolic acid and oleanolic acid, such as China
Extracted using ethanol in the text of research one of seabuckthorn fruit peel chemical composition, upper silicagel column, chloroform, ethyl acetate, third are then used respectively
Ketone, ethanol elution obtains 4 parts, by silicagel column on chloroform portion eluent, with petroleum ether and ethyl acetate mixed solvent ladder
Degree wash-out, merges 49-56 parts of part, there is Precipitation, the precipitation for obtaining, with obtaining ursolic acid after recrystallizing methanol.Above-mentioned side
Method is eluted using strong organic solvent, and needs post twice, it is impossible to big production.Chinese patent：200910216298.9 " it is a kind of from
The method that ursolic acid is extracted in sea-buckthorn " describes one kind and ursolic acid is extracted from seabuckthorn fruit peel using CO_2 supercritical technology
With the method for oleanolic acid, this method slightly carries for seabuckthorn fruit peel ursolic acid, not yet determines ursolic acid content.
Chinese patent 200910233824.2：" a kind of preparation method of ursolic acid " describes a kind of using macroreticular resin point
The method for extracting ursolic acid from fresh glossy privet leaf from technology, the ursolic acid purity that this method is extracted is higher.
Chinese patent 201110127055.5 " a kind of method for extracting ursolic acid as raw material with Folium Forsythia " describes one kind
The method that ursolic acid is extracted using crystallisation.
The preparation method of current ursolic acid is a lot of, but most of complex process, and yield is relatively low, and production cost is higher, no
It is suitable for mass production.
The present invention is separated with the extraction that seabuckthorn fruit peel carries out ursolic acid as raw material, seabuckthorn fruit peel sea-buckthorn squeezed the juice after taking seed
Using macroreticular resin isolation technics separating and preparing ursolic acid after slightly carrying, energy resource consumption is few, and low production cost, yield is greatly improved.
Seabuckthorn fruit peel is fully used, so as to reduce waste, sea-buckthorn is made the best use of everything.
