Definitions
- the present invention relates to an extract of Punica granatum variety Cybele and a cosmetic composition comprising said extract.
- the invention also relates to the cosmetic and/or dermatological use of said extract or said composition for skin care, in particular for combating skin aging.
- the pomegranate tree belonging to the species Punica granatum, is a shrub measuring on average 3 to 6m in height and classified in the Lythraceae family.
- Pomegranates are globose berries with a leathery pericarp which, when ripe (i.e., from September to October), turns from yellow to red-orange or even purplish to black depending on the variety.
- the fruit is topped with the remains of the flower calyx, forming a serrated crown and giving it an atypical shape that is easily identifiable.
- the pomegranate is made up of 6 to 12 whitish membranous cells with a bitter taste containing numerous triangular seeds called arils. These seeds have a fleshy and gelatinous mesocarp, generally acidic and sweet, representing the edible part of the fruit.
- Punica granatum varieties producing red fruits are preferred in cosmetic formulations or food supplements, etc.
- the fruit constitutes the most commonly used source of extraction, but it is above all a specific part which is exploited, namely the peel or the seed, which requires additional separation steps which have direct effects on the cost of extraction.
- documents FR 3 031 901, WO 2021/064034 or WO 2021/209593 describe extracts of Punica granatum producing red fruits and their cosmetic uses, in particular for the production of oral compositions or food supplements, sun prevention or to combat acne.
- sebocytes participate in the pathophysiology of acne due to their role in producing sebum.
- dysseborrhea makes the sebum of poor quality due to a deficiency in vitamin E, in particular.
- the elements of sebum, and more particularly squalene, are oxidized.
- Oxidized lipids are known for their pro-inflammatory and cytotoxic properties (ii) hyperseborrhea is an overproduction of sebum or excess sebum that induces skin problems such as acne. Hyperseborrhea contributes in particular to the proliferation of Cutibacterium acnes which contributes to the local inflammatory reaction.
- the extracts described by the documents FR 3 031 901, WO 2021/064034 or WO 2021/209593, mentioned above, require different phases of concentration, or even purification of particular phytochemical families in order to increase their effectiveness. These processes therefore require additional manufacturing steps which have direct effects on energy consumption and therefore on the overall production cost.
- Punica granatum var. Cybele is an ornamental variety, which also has agronomic advantages: it is effective in repelling insect pests and allows cultivation without the use of pesticides. It is a major asset for biodynamic or co-culture production.

Some applications, more rarely cited, refer to skin conditions.
- Traditional Chinese medicine in fact, describes the fruit as useful for treating furunculosis or bedsores.
- antioxidant properties mainly carried by its content of polyphenolic compounds (flavonoids, tannins, anthocyanins); anti-inflammatory, anti-bacterial, anti-acne, healing, anti-aging properties or even a depigmenting activity.
- Punica granatum extract in particular an alternative to existing extracts having cosmetic properties that are at least equivalent, or even improved, compared to the Punica granatum extracts of the state of the art, in particular to effectively combat skin ageing, which is free of toxic or irritant effects, effective for cosmetic skin care and the production of which is less costly, less energy-intensive and less water-consuming (e.g., eco-design approach) compared to the manufacturing processes of the state of the art.

- the extract and the vegetable cake are then separated by filtration on a 200um mesh nylon cloth.
- the crude extract is then filtered under pressure on cellulose plates then on a cellulose acetate membrane with a cut-off threshold of 0.2iim.
- Method 2 NaDES FGE115, extracts 2A and 2B
- the dried pomegranate ground material is extracted by the NaDES solvent Fructose/Glycerin/Water with a mass composition of 50/25/25 (denoted FGE115), according to a mass ratio of ground material/solvent of 5:95 for 3 hours at 70°C with continuous mechanical stirring.
- the extract and the vegetable cake are then separated by filtration on a 200 um mesh nylon cloth.
- the crude extract is then filtered under pressure on cellulose plates then on a cellulose acetate membrane with a cut-off threshold of 0.2 um.
- the dried pomegranate ground material is extracted with the Ethanol/Water solvent with a mass composition of 60/40 (denoted EtOH/Water), according to a ground material/solvent mass ratio of 5:95 for 3 hours at 70°C with continuous mechanical stirring.
- the extract and the plant cake are then separated by filtration on a 200um mesh nylon cloth.
- the crude extract is then filtered under pressure on cellulose plates and then on a cellulose acetate membrane with a cut-off threshold of 0.2um.
- the dry extract concentration of the liquid extract is determined on a sample by drying at 105°C.
- the ethanol in the extract can be substituted by a glycol, such as propanediol, in order to facilitate its use in the greatest number of cosmetic compositions.
- the hydro-ethanolic extract is then concentrated under reduced pressure until a soft extract is obtained.
- the soft extract is then completely solubilized in the hydro-glycolic solvent of process 1 (Propanediol/Water 60/40 m/m), at a dry extract concentration identical to the dry extract determined on the hydro-ethanolic extract.
- the hydro-glycolic solution is then filtered under pressure on cellulose plates then on a cellulose acetate membrane at a cut-off threshold of 0.2 pm.
- Example 3 Physicochemical characterization of purple and red pomegranate extracts
- the visual appearance is determined for the pure extract placed in a colorless and transparent glass tube with a diameter of 1 cm.
- the L*a*b* color indices are measured on the pure extract in a square PMMA plastic tank with a 10 mm optical path, with the 10° observer and the D65 illuminant (Konica Minolta equipment).
- the dry extract is determined by halogen drying by applying a drying program at 125°C with preliminary stage (180°C - 5min) for a stopping criterion of 3, for a test sample of 3g of pure extract (Mettler Toledo equipment). This determination is not technically feasible for NaDES FGE115 extracts, given the non-volatility of the solvent.
- Example 4 Characterization of the phytochemical composition of purple and red pomegranate extracts
- the concentration of total polyphenols in the extracts is measured according to the Prussian blue method by absorption spectrophotometry at 725 nm after reaction of the extract with iron III chloride and potassium hexacyanoferrate III (Mettler Toledo UV-visible spectrophotometer). A calibration range is carried out with the punicalagin standard (Sigma, mixture a and P). The concentration of total polyphenols expressed in punicalagin equivalent is determined in g per 100 g of extract.
- the concentration of total polyphenols, punicalagins a and P and ellagic acid is significantly higher in all purple pomegranate extracts according to the invention compared to that of red pomegranate extracts.
- the PDo/Water solvent allows to obtain the highest concentration of total polyphenols, punicalagins a and P and ellagic acid and total anthocyanins.
- the 2 other extraction solvents e.g., FGE115 and EtOH/Water
- FGE115 and EtOH/Water also allow to extract these families but with different quantitative performances depending on the molecules.
- Example 5 Evaluation of the antioxidant activity of purple and red pomegranate extracts
- 1,1-Diphenyl-2-picrylhydrazyl is a free radical, stable at room temperature, which has a dark violet color in solution in ethanol and absorbs in the wavelengths between 510 and 530 nm.
- DPPH Due to its structure, DPPH can be reduced by accepting a hydrogen atom from other compounds. This reduction is accompanied by a disappearance of the violet color of the solution and therefore a drop in absorbance directly proportional to the number of atoms captured.
- the products to be tested are added to an ethanolic solution of DPPH, incubated for 30 minutes at room temperature (18-25°C) away from light, then an absorbance reading is taken at 518 nm using a spectrophotometer.
- An experimental blank is carried out using an ethanol solution alone to which the products to be tested are added. The blank values are deduced from the experimental values to avoid any possible interference linked to the specific color of the products.
- Example 6 Evaluation of the anti-inflammatory activity of purple and red pomegranate extracts
- NHEKs normal human epidermal keratinocytes
- the assay is performed using monolayer cultures of KEHN.
- the cytokines IL-6 and IL-8 are assayed in the supernatants of KEHN cultures pre-incubated in the presence of the test products before being stimulated for 24 hours by a mixture of interferon gamma (IFN-y) and tumor necrosis factor alpha (T Fa) in the presence of the test products.
- IFN-y interferon gamma
- T Fa tumor necrosis factor alpha
- Two assay methods are then used: an ELISA assay and a flow cytometry assay.
- Example 7 Evaluation of the sebum-regulating activity of purple and red pomegranate extracts
- sebocytes which are the specialized cells producing the lipids constituting the skin's sebum, were used in in vitro culture.
- Sebocytes are incubated for 30 minutes with the BODIPYTM fluorescent probe, which stains lipids in fluorescent green. Lipids are then visualized by fluorescence (Ex493/Em503) and then quantified by image analysis with the Cytation 5 multimode plate reader (Agilent Biotek). Sebocyte cell nuclei are labeled with DAPI to normalize the amount of lipids per cell.
- extract 1 A has sebum-regulating properties by reducing lipid synthesis in sebocytes.
- the sebum-regulating effect of extract IA is stronger at 0.2% than at 0.1%.
- the quantities of lipids measured in sebocytes treated with the IB extract are equivalent to the quantities measured in untreated sebocytes. In other words, the IB extract does not have sebum-regulating properties.
