Abstract
Description
La présente invention concerne une composition cosmétique à base d'extraits de feuilles de mûriers (morus alba). The present invention relates to a cosmetic composition based on extracts of mulberry leaves (morus alba).
On sait que les vers à soie ne consomment que des feuilles de mûriers sélectionnés (comme par exemple le "Kokuso 21"), à exclusion de toutes autres feuilles. We know that silkworms consume only selected mulberry leaves (such as "Kokuso 21"), to the exclusion of all other leaves.
Compte tenu du fait que, grâce à cette nourriture unique, le ver à soie grossit en 25 jours de 10.000 fois, change en 4 mues à la fois de peau et de tête, construit un cocon avec 1 kilomètre et demi de fils de soie, se transforme en chrysalide, et enfin se métamorphose en papillon, c'est-à-dire en un insecte parfait, nous avons été amenés à étudier et analyser des extraits de feuilles du mûrier.Given the fact that, thanks to this unique food, the silkworm grows in 25 days by 10,000 times, changes into 4 moults of both skin and head, builds a cocoon with 1 and a half kilometers of silk thread, turns into a chrysalis, and finally turns into a butterfly, that is to say into a perfect insect, we were led to study and analyze extracts of mulberry leaves.
La teneur exceptionnelle de ces feuilles en acides gras insaturés indispensables et bien entendu d'autres substances biologiques, laissait prévoir une application biologique.The exceptional content of these leaves in essential unsaturated fatty acids and of course other biological substances, suggested a biological application.
Selon le brevet d'invention publié sous le numéro 2 336 941 (Nippon Shinyaku Co, Ltd.), on connait des extraits de mûrier contenant principalement du 2-hydroxyméthyl-3,4,5-trihydroxypipéridine, ayant une action sur la biosynthèse des lipides, notamment une action anti hyperglycémique . Ces extraits sont obtenus de préférence à partir de la poudre sèche de racines et d'écorces de cette plante. L'écorce a également été utilisé comme diurétique ou antitussif en médecine traditionnelle chinoise. Enfin récemment de nombreux acides aminés ont été trouvés dans les feuilles du mûrier (Poonia et coll.,
Chem. Abstr. 92, 212.174j, (1980); Imanishi et coll.According to the invention patent published under number 2 336 941 (Nippon Shinyaku Co, Ltd.), there are known mulberry extracts containing mainly 2-hydroxymethyl-3,4,5-trihydroxypiperidine, having an action on the biosynthesis of lipids, in particular an anti hyperglycemic action. These extracts are preferably obtained from the dry powder of roots and barks of this plant. The bark has also been used as a diuretic or cough suppressant in traditional Chinese medicine. Finally, recently, numerous amino acids have been found in the leaves of the mulberry tree (Poonia et al.,
Chem. Abstr. 92, 212.174j, (1980); Imanishi et al.
Chem. Abstr. 101, 71710w (1984). Cependant il semble que des extraits de feuilles de mûrier n'aient pas encore fait l'objet d'études sur le corps humain et, en tous cas, pas d'études cosmétiques ou dermo-pharmaceutiques. Chem. Abstr. 101, 71710w (1984). However, it seems that extracts of mulberry leaves have not yet been the subject of studies on the human body and, in any case, no cosmetic or dermo-pharmaceutical studies.
Nous avons maintenant trouvé que des extraits de feuilles du mûrier ont des propriétés eudermiques et eutrophiques permettant leur utilisation en cosmétique. We have now found that extracts of mulberry leaves have eudermic and eutrophic properties allowing their use in cosmetics.
L'invention concerne donc une composition cos métique à base d'extraits de feuilles du mûrier (Morus alba) extraits dans lesquels on a détecté, d'une façon inattendue, une forte proportion de flavonoldes(bioflavonoldes),dont les travaux les plus récents ont par ailleurs mis en évidence l'importance biologique, particulièrement dans le revêtement cutané (C. DURANDEAU,
Thèse doct.univ.Bordeaux, 1978; RAO C.N. et coll.The invention therefore relates to a cosmetic composition based on extracts of mulberry leaves (Morus alba) extracted in which an unexpectedly high proportion of flavonoldes (bioflavonoldes) has been detected, including the most recent works have also highlighted the biological importance, particularly in the skin covering (C. DURANDEAU,
Thesis doct.univ.Bordeaux, 1978; RAO CN et al.
Indian J. of Biochemistry and Biophysics, 1981, 18, 224).Indian J. of Biochemistry and Biophysics, 1981, 18, 224).
L'invention concerne donc en particulier les compositions à base d'extraits de feuilles de mûrier contenant des flavonoïdes. Les extraits contiennent en outre des acides aminés essentiels, des acides gras insaturés (acides gras essentiels), des lipides apolaires (glycérides, cholestérol, et ses esters, squalène, etc.), mis en évidence après séparation chromatographique et analyse des divers extraits.The invention therefore relates in particular to compositions based on extracts of mulberry leaves containing flavonoids. The extracts also contain essential amino acids, unsaturated fatty acids (essential fatty acids), non-polar lipids (glycerides, cholesterol, and its esters, squalene, etc.), demonstrated after chromatographic separation and analysis of the various extracts.
L'extraction est effectuée de manière connue en soi, de préférence à l'aide de solvants organiques usuels tels que l'éther de pétrole, acétone (éventuellement aqueuse), choroforme, méthanol ou éthanol (éventuellement aqueux), éther, acétate d'éthyle, etc, séparément ou en mélange, et elle peut être suivie d'un traitement par chromatographie, par exemple sur colonne de gel de silice, dans le cas où une fraction de composants plus homogène est désirée (par exemple les flavonoldes). En général plusieurs extractions peuvent s'avérer utiles. The extraction is carried out in a manner known per se, preferably using usual organic solvents such as petroleum ether, acetone (optionally aqueous), choroform, methanol or ethanol (optionally aqueous), ether, acetate. ethyl, etc., separately or as a mixture, and it can be followed by a treatment by chromatography, for example on a column of silica gel, in the case where a fraction of more homogeneous components is desired (for example the flavonoldes). In general, several extractions can be useful.
Les exemples suivants non limitatifs illustrent ltobtention et l'utilisation d'extraits selon l'invention. The following nonlimiting examples illustrate the obtaining and use of extracts according to the invention.
