Definitions
- the invention relates to a composition
- a composition comprising a mixture of at least one extract of Vitis vinifera, of at least one extract of Vaccinium angustifolium and at least one extract of Crocus sativus, in particular a mixture of catechin and / or epicatechin, safranal and crocetin (aglycon and / or glycosylated).
- Such a composition can be used as a nutritional product or a medicament and exhibits a synergistic action for improving cognitive functions and / or executive functions in humans or animals.
- Nutrition has been suggested to be an important factor in preventing impaired cognitive functions.
- patent application FR 1560263 describes a mixture of molecules obtained from Vitis vinifera and Vaccinium angustifolium, comprising: at least 1% of catechin and / or epicatechin, and at least 5 ppm of ferulic acid. Such a mixture is therefore known as well as its effects on the cognitive functions of the human being during chronic intake.
- the Mediterranean diet and its derivatives such as the MIND or DASH diet seem to be beneficial in preventing cognitive decline during aging.
- This type of diet is rich in neuroprotective nutrients such as flavonoids and other polyphenols, carotenoids, omega 3 fatty acids, certain vitamins (folate, vitamin E in particular) and certain minerals have been the subject of much research in order to identify their effects on an individual basis.
- Crocetin is an aglycon form of crocin which is metabolized to crocetin by the body, either after administration.
- the objective of the invention is to provide a composition exhibiting greater efficiency in the fight against cognitive decline than the specific molecules consumed individually or the mixtures of known molecules.
- the invention relates to a composition
- a composition comprising a mixture of at least one extract of Vitis vinifera, of at least one extract of Vaccinium angustifolium and of at least one extract of Crocus sativus.
- said mixture comprises a mixture of molecules comprising:
- composition according to the invention comprises flavanols, in particular catechins and / or epicatechins, combined with specific molecules of saffron: safranal and crocetin in aglycone and / or glycosylated form.
- Catechins and epicatechins are compounds of the flavonoid family, in particular of the flavanol subclass. They are also known under the names of catechol and epicatechol and are powerful antioxidants which help in particular to prevent inflammatory and coronary diseases but also to maintain or increase cognitive performance.
- Safranal is a volatile organic compound isolated from saffron and in particular responsible for its aroma. It can be extracted from several plants such as Crocus sativus, Centaurea sibthorpii, Centaurea consanguinea, Centaurea amanicola, Erodium cicutarium, Chinese green tea, Calycopteris floribunda, Crocus heuffelianus, Sambucus nigra, Gardenia jasminoides, Citrus limonum, but is mostly extract of Crocus sativus.
- Crocetins in aglycon and / or glycosylated form have a multifunctional role on neuroprotection, in particular by modulating the aggregation of b-amyloid and tau peptides slowing cognitive decline and amnesic disorders (Finley JW, Gao S. A Perspective on Crocus sativus L. (Saffron) Constitute Crocin: A Potent Water-Soluble Antioxidant and Potential Therapy for Alzheimer's Disease. J Agric Food Chem. 2017 Feb 8; 65 (5): 1005-20). As before, it can be extracted from Crocus sativus or Gardenia jasminoides and is mainly responsible for the color of saffron.
- the specific combination as well as the amount of molecules present in the present composition exhibit a synergistic effect and therefore an improved effect on cognitive decline.

Ferulic acid provides neuroprotection against oxidative stress-related apoptosis after cerebral ischemia / reperfusion injury by inhibiting ICAM-1 mRNA expression in rats. Brain Res. 2008; 1209: 136-150).
- its antioxidant activity has been tested in Alzheimer's disease (Sgarbossa A, et al. Ferulic Acid: A Hope for Alzheimer's Disease Therapy from Plants. Nutrients.
- Resveratrol is particularly known to be present in grapes. However, it can also be obtained from other plant sources, in particular from Polygonum cuspidatum but also by biotechnological means. It has many beneficial activities for humans or animals, including an improvement in working memory, learning, spatial memory and spontaneous motor activity (Abraham J, Johnson RW. Consuming a diet supplemented with resveratrol reduced infection-related neuroinflammation and deficits in working memory in aged mice. Rejuvenation Res [Internet] 2010/01/01. 2009; 12 (6): 445-53).
- Quercetin also has significant neuroprotective activity (Dajas F, et al. Neuroprotective actions of flavones and flavonols: mechanisms and relationship to flavonoid structural features. Cent Nerv Syst Agents Med Chem. 2013; 13 (l): 30-5 ) and it is also known that the consumption of foods rich in anthocyanidins (aglycones and / or glycosylated) can prevent memory deficiencies and improve cognitive performance (Barros D, et al. Behavioral and genoprotective effects of Vaccinium berries intake in mice Pharmacol Biochem Behav. 2006; 84 (2): 229-34).

- Age-related cognitive decline is the term used to describe the non-pathological form of deterioration of memory and cognitive functions resulting from the aging process within normal limits, given a person's age. It is a complex process, with the first signs emerging in humans between the ages of 35 and 65, without specific neurodegenerative lesions. Progressive cognitive decline is noticeable by the onset of minor cognitive problems that affect 15-20% of the population aged 65 or over, and represents an unstable state. However, certain pathological forms can occur in addition to this "normal" cognitive decline.
