Description

A kind of blueberry leaf flavones Essence and preparation method and application
Technical field
The present invention relates to a kind of blueberry leaf flavones Essence and preparation method and application, belong to cosmetic field.
Background technology
Flavonoid substances belong to the secondary metabolite of plant, are that a class has multiple biological activities plant polyphenol kind thing Matter.Research shows that Flavonoid substances can reduce the adhesion effect between the endothelial cell in inflammatory reaction and immunocyte, from And slow down inflammatory reaction.Research shows the content of Flavonoid substances in blueberry (Vaccinium uliginosum L.) leaf very Height, and species is abundant, and with anti-aging, anti-inflammatory, antiallergy, antiviral, anticancer strengthen cell membrane, make damaged cell again The multi-efficiency such as raw.Blueberry leaf can also be used to the chronic inflammation occurred and the urgency occurred by damage on processing skin histology Property inflammation, it is possible to prevent and treat in oral cavity produce inflammatory reaction.
IL-10 is a kind of T h1 Cellular immunity suppression factors, thin in regulation Th1 with immunosupress and anti-inflammatory effect Played an important role in the cell factor in born of the same parents source, thus be referred to as CSIF in early days.IL-10 belongs to cell Interference family in the factor, research find endogenous and exogenous IL-10 can on transcriptional level strong inhibition IL-1, IL-6, IL-8, tumor necrosis factor-alpha (TNF-α), GM-CSF, G-CSF synthesis.Nearly ten years, research thinks that IL-10 is main It is activation by suppressing IKK or NK-k β DNA binding abilities, so that suppressing NK-k β starts related proinflammatory factor gene Transcription.Therefore anti-inflammatory efficacy is evaluated with IL-10 expression quantity on a molecular scale, be in inflammation early period of origination even inflammation still The effective ways that the nonevent stage is evaluated it.Some treatment psoriasis medicine for example corticosteroid, Calcipotriol, Vitamine D3, anthraline etc. can dramatically increase IL-10 expression, and research confirms that IL-10 function of resisting psoriasis is by regulation Caused by keratinocyte secrete cytokines.Further IL-10 is supported to be played an important role in onset of psoriasis, clinically Through treating psoriasis using Recombinant Human IL-10.In addition, scholar generally believes that IL-10, IL-8 can be as psoriasis disease development Early monitoring index.
At present for the research of anti-inflammatory class cosmetics, it is broadly divided into live body, structural efficacy validation, molecular level is ground Study carefully the form for being only limitted to that zooblast is pattern, with skin progenitor cell to the rare report of flavones anti-inflammatory efficacy, and pass through mankind's table Skin stem cell carries out the identification of blueberry flavones anti-inflammatory efficacy and also belonged to first.

The identification of embodiment 2, blueberry leaf flavones anti-inflammatory efficacy
First, the separation of application on human skin epidermal stem cells
By the ring cutting prepuce tissues of people, abundant washing by soaking 3 times in the tincture of iodine and 75% alcohol, adipose tissue is cut Abandon, and skin abbreviation 5mm × 5mm fritters are put into the centrifuge tube equipped with the neutral proteinases of Dispase II, 4 DEG C of enzymolysis Overnight, then by skin histology take out, be put into DPBS, separated epidermis and dermal tissue with tweezers.Epidermis is shredded, dress is put into There is 8ml 0.125% trypsin treatment 10min, obtain ferment treatment liquid.Ferment treatment liquid is centrifuged into 8min under 360g, collected Supernatant, adds KGM basal mediums and terminates digestion, be denoted as digestive juice 1.Sediment fraction is added to 0.125% tryptose again Enzyme secondary digestion, collects supernatant, adds KGM basal mediums and terminates digestion, will terminate postdigestive solution and cross 100 μm successively Filter membrane with 40 μm, obtains filtrate, and the filtrate is mixed with digestive juice 1,4 DEG C, 360g centrifugation 8min, abandons supernatant, obtains after precipitation Cell.(BD, catalogue are purchased from the integrins of β 1 (being purchased from Santa Cruz, catalog number is sc-9970) and CD49 Number for 555736) antigenic mark cell, sorted by flow cytometer.The double positive cells of two kinds of marks of selection, be Application on human skin epidermal stem cells.
2nd, the preparation of blueberry leaf flavonoids solution
Blueberry leaf flavones prepared by embodiment 1 is dissolved in sterile PBS buffer, is configured to 60 μ g/mL solution, will be molten Liquid crosses 0.45 μm of miillpore filter.
3rd, the application on human skin epidermal stem cells for separating step one are with 2 × l06The density in/hole is inoculated with 6 orifice plates and uses application on human skin Epidermal stem cells medium culture, per hole add 5 μ L step 2 prepare blueberry leaf flavonoids solution, respectively handle cell 0,15, 30th, 60,90 and 120min, is denoted as processing 0,15,30,60,90 and 120min groups respectively.
4th, the total serum IgE and reverse transcription for extracting the cell of each treatment group are cDNA.
5th, quantitative fluorescent PCR
IL-10 is one kind in anti-inflammatory factors, is the important immunosuppressive factor of body, is mainly produced by T cell, and it is led The biological characteristics wanted is the effect for suppressing the inflammatory factors such as IL-2.When the skin is exposed to uv rays, keratinocyte Inflammation inhibiting factor, such as IL-10 and TGF-β can be secreted, its effect is the propagation by suppressing lymphocyte and then alleviated Inflammatory reaction through generation.
(1) respectively to handle 0,15,30,60,90 and 120min groups cDNA as template, quantitative fluorescent PCR is prepared by table 1 Reaction system (before use, 40uL Dye I is added in 1mL MIX), uses ddH2O supplies system to 20 μ L, analyzes each processing The expression of the IL-10 genes of group cell, while being used as internal reference using β-actin.
The quantitative fluorescent PCR reaction system of table 1
The primer of each gene is as shown in table 2 in quantitative fluorescent PCR.
The fluorescence quantification PCR primer of table 2
Experiment sample is expanded using ABI7300 quantitative real time PCR Instruments, quantitative fluorescent PCR program is as shown in figure 1,20 μ L are anti- Answer system, 36 circulations.
(2) anti-inflammatory factors gene (IL-10) expression analysis
The IL-10 of each treatment group relative expression quantity result is as shown in Figure 2.
Fig. 2 shows that influence of the blueberry leaf flavones to IL-10 expression quantity, which changes with time, is presented the overall trend improved. In the blueberry leaf flavones processing prolonged scopes of 0min to 60min, the change of IL-10 expression quantity is not obvious, but 60min is arrived 90min time IL-10 expression quantity starts to be significantly improved, subsequent 30min be 90min to 120min time in its Expression quantity is declined slightly, but compared with initial value, stills remain at a relatively high level.Entirety sees that blueberry leaf flavones is to IL-10 Expression there is facilitation, reach the level of signifiance (P < 0.05), therefore blueberry leaf flavones prepared by embodiment 1 can be drawn With anti-inflammatory efficacy.
The preparation of embodiment 3, blueberry leaf flavones Essence
The formula and manufacture craft of blueberry leaf flavones Essence are as shown in table 3.
