- Smelophyllum capense root bark powder is prepared by grinding dried root bark of this plant from South Africa. Then 200 g of this powder are macerated for 2 h in 2 l of methanol. The whole is brought to reflux for 3 h, then it is allowed to cool and filtered. on sintered glass. The filtrate is evaporated to dryness. The residue, weighing 44.6 g, is taken up in 350 ml of methanol. Precipitation is carried out by adding 1.75 l of ethyl ether to this solution, then filtering. The precipitate is then dried over a solid dehydrating agent such as P2O5. An amount of approximately 27 g of this precipitate is then dialyzed for 4 days against 270 ml of demineralized water, then lyophilized. 13.6 g of extract according to the invention, called extract 1, are thus obtained.
- Cultures of healthy adult dermis fibroblasts are carried out using the explant method using a facial skin sample obtained from a woman aged 60 years during a facelift.
- Fibroblasts are grown to confluence in 199 E medium (Gibco) supplemented with 2 mM L-glutamine (Gibco) and 10% v / v fetal calf serum (Gibco) at 37 ° C in an atmosphere of 5% of humidified CO2.
- the confluent primary cultures are harvested with a 0.1% solution of trypsin and 0.02% EDTA in phosphate buffered saline (PBS) at pH 7.2 and the cells are then seeded at the density of 10 ⁇ fibroblasts per well, in microculture plates (Falcon) with 96 wells, in the presence of the same culture medium as that described above.
- PBS phosphate buffered saline
- the medium is removed and replaced by a medium of the same composition as the medium described above, except that it does not contain serum and that 25 ⁇ M of acid have been added L-ascorbic in the form of sodium salt.
- this new medium contains or not the product to be tested (extract 1 ⁇ ) depending on whether it is a treated culture or a control culture. Then incubated for an additional 48 h at 37 * C.
- the test product (extract I j) was dissolved in DMSO prior to incorporation into the culture medium (final DMSO concentration in the medium is 0.1% v / v).
- the amount of type I collagen secreted by the cells in the serum-free medium after 48 h of incubation with the mixture or the individual component is determined by an ELISA test as previously described in the publication by Dumas M. et al. , Mech. Aging Dev. (1994) 73, 179-187, and that of Grimaud JP et al., In: Methods of Enzymatic Analysis (Bermeyer, HU, ed.), VCH Publishers, einheim, (1986), 186-201.
- the serum-free incubation mediums and the remaining cells homogenized by sonication in ice is collected and transferred to wells of a plastic immunoplate (NUNC) for an incubation of 24 hours at 4 ° C to allow the adhesion of secreted collagen.
- Protease inhibitors ethylmaleimide, phenylmethylsulfonyl fluoride, ethylenediaminetetraacetate, each in a final concentration of 1 mM
- the plates are then reinserted with PBS. A similar washing step is carried out after each plaque treatment.
- the percentage of stimulation A of the synthesis of collagen gene I is calculated by comparing the amounts of collagen I secreted in the control cultures (receiving no product to be tested) C 0 and in the treated cultures, from the following formula:
- Smelophyllum capense produced a significant activity of stimulation of the synthesis of collagen I by fibroblasts.
- the extract of Smelophyllum capense can be used for products intended to combat skin aging or requiring an increase in local synthesis of collagen as is the case during a treatment of wrinkles or to help improve the skin healing.
- the extracts of Smelophyllum capense can advantageously be used, thanks to their property of stimulating the synthesis of collagen, as active agent, in cosmetic or pharmaceutical compositions, in particular dermatological, as defined above.
- Part of the aqueous excipient is used with Carbopol to separately prepare a gel, the other part of the aqueous excipient is used to be mixed with the other components and the gel is added to the solution obtained in order to obtain a gelled composition forming the massage gel.
- This massage gel composition can be used three times a week for two months at the bust.
- Hyaluronic acid 1 g Aqueous excipient containing a possibly flavored preservative qs 100.00 g The extract is first dissolved in the solubilizing agent, then is added to the aqueous excipient to which hyaluronic acid is added.
- the lotion obtained can be used for a three-week treatment on areas sensitive to sagging, such as the belly, thighs.
- This cream applied twice a day, restores the qualities of firmness, elasticity as well as the skin barrier properties and the radiance of young skin.
