Definitions
- the present invention relates to a method for extracting a firming active ingredient from Lent / nus edodes, a fungus also commonly known as Shiitake, for the body, the bust and the face, the active ingredient obtained and associated compositions.
- Lent / nus edodes a fungus also commonly known as Shiitake
- Shiitake a fungus also commonly known as Shiitake
- the active ingredient obtained and associated compositions it is a cutaneous aging which affects all the structures of the skin, in particular the dermo-epidermal junction. This junction flattens and moreover, the cutaneous ibrillary network deteriorates.
- This cutaneous ibrillary network is also known by the name extracellular matrix or ECM.
- ECM extracellular matrix
- This f ibrillary network produced by fibroblasts and keratinocytes, is composed of macromolecules, mainly collagen fibers and elastin.
- This f ibrillary network thus comprises insoluble, rigid and stable fibers, which, from their spatial organization, give the connective tissues their solidity and their mechanical resistance.
- this network has biological functions of exchange and intercellular communication allowing good anchoring of the epidermis / dermis and integrity of the skin tissue.
- this network is subjected to a metabolic balance which is managed by specific enzymes, metalloproteinases or MMPs, which are capable of degrading different components of the extracellular matrix.
- MMPs metalloproteinases
- the activity of metalloproteinases is racing and tissue inhibitors no longer control this activity.
- the collagen fibers are degraded in large numbers without being replaced and this in an anarchic manner, which leads to a destructuring of the extracellular matrix.
- the skin loses its suppleness, its elasticity and it sags.
- the solution proposed by the present invention is to control the activity of MMPs.
- the inhibitor TTMP-1 acts in particular on MMP-1 and the inhibitor TIMP-2 acts in particular on MMP-2.
- the method according to the present invention relates to a method for extracting an active principle from Lenfinus edodes, rich in oligosaccharides and uronic acids in order to inhibit the activity of certain metalloproteinases.
- the invention also covers the active ingredient obtained and suitable compositions.
- FIG. 1 a table of the inhibitory effect of the synthesis of MMP-1
- FIG. 4 a chromatogram of the degrees of polymerization of the oligosaccharides
- FIGS. 5A and 5B table of the results obtained relating to the elasticity
- FIG. 6 table of the results obtained relating to the tone
- the dry matter is obtained by passing the active ingredient extracted in an oven at 105 ° C for 16 hours.
- the amount of dry matter obtained is between 20 and 200 g / l, more particularly between 50 and 100 g / l.
- the pH is measured by the potentiometric method at room temperature.
- the pH is between 4 and 10, more particularly between 5 and 10.
- Determination of protein content The determination is carried out by the Lowry method.
- the protein content is between 10 and 100 g / 1 and more particularly between 10 and 50 g / 1.
- Determination of total sugar content This determination is carried out by the Dubois method (DUBOIS, M ⁇ & al,
- the reducing sugars give a colored compound in the presence of phenol and sulfuric acid.
- the optical density of the colored composition is read and the sugar content is read on a standard curve produced under the same conditions with a standard composition containing 1/3 mannose, 1/3 glucose and 1/3 galactose over a range. from 25 to 100 / jg / ml.
- the rate of total sugars is between 5 and 50 and more particularly between 5 and 20 g / 1.
- Uronic acids are the constituents of repeating units specific to all acidic polysaccharides.
- galacturonic acids are in particular the markers of polysaccharides of the pectin type. They can be detected by a comparative analysis of coloring, compared to a standard range of galacturonic acids.
- the active principle according to the present invention is obtained a rate of 0.5 g / l
- This curve is shown in Figure 4 and shows that the majority of oligosaccharides have a degree of polymerization less than or equal to 5 monosaccharide units.
- Human ibroblasts are incubated with the active ingredient. Some samples are subjected to treatment with irradiation with UVA at a power of 20 joules / cm 2 to give an order of magnitude and others at no irradiation.
- the cell supernatant makes it possible to carry out the assay of the level of MMP-1 by ELISA method.
- the rate is expressed in ng / ml.
- the table in Figure 1 shows the results obtained.
- the variation ⁇ % is obtained by comparing the rates obtained for the sample treated with the active ingredient and that of the control.
- the active principle according to the present invention causes an inhibition of the synthesis of MMP-1, this in a dose-dependent manner.
- this inhibition is verified under particularly aggressive stress conditions generated by the irradiation.
- the operating protocol aims to carry out an immunohistochemical study which makes it possible to obtain quantitative results.
- the visualization is carried out by means of a microscope connected to an image analyzer.
- TIMP-1 level is assayed by ELISA method in supernatants of control human fibroblast cultures on the one hand and placed in the presence of active principle on the other hand.
- the activity rate is expressed in ng / ml and the results are collated in the table in FIG. 3.
- the active principle according to the present invention causes an increase in the synthesis of TIMP-1, this more particularly under stress conditions generated by irradiation.
- the study focuses on the biomechanical properties of the skin, namely elasticity, tone and fatigability.
- the active principle is introduced into a 5% emulsion and the effects are quantified on two groups, one A of 10 volunteers of ages between 24 and 40 years, the other B of 15 volunteers of ages between 45 and 70 years, before and after 28 days of twice daily application of this emulsion and placebo for 28 days on the forearm. Under the same conditions, the test is carried out on the bust of a group ⁇ of 10 volunteers aged between

- a commercially available measuring device known under the name Cutometer SEM 575.
- Such a device has a probe with an orifice subjected to a constant vacuum for a constant period.
