Description
Technical field
The present invention relates to a kind of ginkgo extract.
Background technology
Ginkgoaceae plant Ginkgo biloba (Ginkgo biloba) is the endemic tree in China, belongs to deciduous tree.Ginkgo appears in
It is plant most ancient in the gymnosperm that carries over after quaternary glacier motion before several hundred million years, the alive ginkgo of existing work
Rare and disperse, upper veteran at the age of one hundred years old has been mended common, and it has all become extinct with the other plant of guiding principle, so ginkgo has activation again
The laudatory title of stone.Mutation and kind have：Yellow leaf ginkgo, tower-like ginkgo, baiera.26 kinds of weeping branch ginkgo, variegated leaf ginkgo etc..
Ginkgo leaf has extensive bioactivity, containing a variety of chemical compositions, mainly including flavonoids, terpene, polysaccharide, phenol
Class.Organic acid.Alkaloid.Amino acid, trace element etc..Wherein, vitamin C, vitamin E, carrotene and calcium, phosphorus, boron,
The Mineral Concentrations such as selenium also very abundant.Flavones ingredient in ginkgo biloba extract has very strong pharmacological activity, main tool
There are following several effects：1st, free radical is eliminated, and the cell destroyed to free radical has certain repair；2nd, brain can be increased
Vascular flow, cerebral vascular resistance is reduced, improve Cerebrovascular disorders；3rd, protect brain cell from ischemic damage；4th, blood vessel is adjusted
Power, strengthen immunity of organisms, to coronary heart diseases and angina pectoris.The diseases such as the cerebrovascular have the effect of certain.At present, China, the U.S., Europe
Ginkgo agent is classified as medicine by alliance etc., and other many countries are also classified as health food or over-the-counter medications.
For the healthy property for knowing very well ginkgo, although existing ginkgo biloba extract has met market in terms of medical value
Purposes, but now it is desirable to improve or in addition performance product.Especially pursuit of the modern female to U.S., people
Wish that develop a kind of ginkgo biloba extract of new type natural plays a role in cosmetic fields such as skin cares, and contained by ginkgo leaf
Flavone component can hinder formation and calmness of the pigment in skin corium, have the function that skin whitening and subtract light color element patch, this
Outside, the trace element such as the manganese in ginkgo leaf, molybdenum, also can scavenging activated oxygen, therefore ginkgo biloba extract is in the valency of cosmetic field
Value has theoretical foundation, and ginkgo biloba extract of the prior art seldom pays close attention to its application value in cosmetic field.Therefore,
The present invention is based on above mentioned problem, there is provided a kind of ginkgo biloba extract for not adding active component.
The content of the invention
The technical problem to be solved in the present invention is, for the drawbacks described above of prior art, there is provided a kind of ginkgo extract,
The ginkgo extract has skin whitening, prevents the characteristics such as pigment patch and smoothing wrinkle.
In order to realize above-mentioned technical purpose, reach above-mentioned technique effect, technical scheme provided by the invention is：A kind of ginkgo
Extract solution, the extract solution include：
(a) flavone compound of 30~50% weight；
(b) ginkgolides of 5~10% weight；
(c) proanthocyanidin of 5~15% weight；
(d) ginkgoic acid of 3~10% weight；
(e) it is less than the polypenthylene alcohols ester of 3% weight；And
(f) it is more than the alkyl phenolic acid compound of 5% weight.
Further, the flavone compound includes glycosides displayed and flavonols.
Further, the ginkgolides includes ginkalide A, ginkolide B, ginkalide C, ginkgo lactones M, ginkgo
Lactones J, wherein content of the bilobalide J in ginkgo extract is not less than 4%.
Research shows, when endocrine disturbance or the imbalance of people, internal foster free radical will be excessive, but now aoxidizes
Thing mutase deficiency, causes excessive oxygen radical to produce oxidation reaction with corium confluent monolayer cells, forms substantial amounts of lipofuscin, cause
Chloasma or cyasma.The present invention can hinder formation of the pigment in skin corium containing more flavone compound, reach beautiful
The effect of white muscle skin and preventing and treating pigment patch.When the skin of human body updates completely simultaneously, the new life that skin corium is formed is thin
Born of the same parents, just by excessive free-radical oxidation, already belong to old when not arriving at also to skin surface when it is arrived to epidermis
Change cell.The glycosides displayed and flavonols that contain in the present invention are all the street cleaners of free radical, can protect corium confluent monolayer cells, are improved
Blood circulation, prevent cell is oxidized from producing wrinkle, there is the effect of crease-resistant.
Further, the proanthocyanidin containing 8% weight in the ginkgo extract.
Further, the ginkgoic acid containing 4% weight in the ginkgo extract.
Further, the alkyl phenolic acid compound includes protocatechuic acid, vanillic acid, caffeic acid, p- coumaric acids, asafoetide
Acid and chlorogenic acid.
It is another object of the present invention to provide the method for preparing ginkgo extract, this method is made up of the following steps：
Step 1：Ginkgo leaf or dry grinding is taken to mix powder with solid-phase reagent to powder, add polar solvent immersion, add
Heat backflow produces the first extract solution.
Step 2：First extract solution is diluted with water, and adjusts pH value 4~6, filtering, and filtrate is added on processed good macroreticular resin
It is finely divided on post, first rinses resin column with purified water, then rinse resin column with sodium acetate solution, then with low concentration to height
Concentration ethanol carries out gradient washes resin column, collects eluent, after miillpore filter refined filtration, obtains the second extract solution.
Step 3：Second extract solution is concentrated, and adding high concentration ethanol makes alcohol content reach 90%, with 20% hydroxide
Sodium adjusts pH value, stands, and supernatant also use filtering with microporous membrane, recovery second through miillpore filter refined filtration after precipitation centrifuge
Alcohol adds purified water to dilute, filled in container, carry out high-temperature sterilization, obtain ginkgo extract to without alcohol taste.
More specifically, according to the ginkgo extract that obtains of the present invention, generally show flavonoid content be 30~
50%, more preferably 37~45%, it is preferably 40~45%.
Usual ginkgo extract of the present invention, contains：
(i) it is less than the polysaccharide compound of 7% weight；
(ii) it is higher than 150ppm biflavone；
(iii) terpene lactones of 10~25% weight.
Contain manganese and molybdenum trace element in the ginkgo extract.
In the ginkgo extract of the present invention：
1st, the present invention has whitening effect, and contained flavone component can hinder pigment in skin corium in of the invention
Formed and calm, have the function that skin whitening and preventing and treating pigment patch,
2nd, the present invention has the effect of smoothing wrinkle, and the flavonol contained in the present invention is the street cleaner of free radical, can be protected
Corium confluent monolayer cells, improve blood circulation, prevent cell is oxidized from producing wrinkle, reduce level of lipid, reduce freckle, profit
Damp skin.The trace element such as manganese and molybdenum simultaneously, it can also remove oxyradical and suppress melanin growth.
3rd, the present invention also has a sterilization and bacteriostasis effect, and the bilobalide J of the invention contained has stronger sterilization and antibacterial
Effect.
