Projet

Grape Metabolomics & Cell Cosmetics

The research project focuses on the metabolomics screening of ancient, rare grape varieties from Loire Valley for the development of plant cell lines producing active cosmetics. The objective is to setup UPLC-DAD-MS/MS-based metabolomics tools to screen a grape germplasm collection from ancient varieties of the Loire Valley (France) to identify varieties with peculiar metabotypes for valorization in cosmetics. The screening includes  sample harvesting from  different  organs and  varieties  as  well  as metabolomics  analysis  targeted  on polyphenols followed by data integration using chemometric tools (PCA, PLS-DA, HCA). Grape varieties of cosmetics interests are selected for plant tissue culturing.

Grape canes are waste biomass of viticulture containing bioactive polyphenols valuable in cosmetics. Whereas several studies reported the cosmetic activities of E-resveratrol, only few described the potential of E-ε-viniferin, the second major constituent of grape cane extracts (GCE), and none of them investigated GCE as a natural blend of polyphenols for cosmetic applications. In this study, we considered the potential of GCE from polyphenol-rich grape varieties as multifunctional cosmetic ingredients. HPLC analysis was performed to quantify major polyphenols in GCE i.e., catechin, epicatechin, E-resveratrol, E-piceatannol, ampelopsin A, E-ε-viniferin, hopeaphenol, isohopeaphenol, E-miyabenol C and E-vitisin B from selected cultivars. Skin whitening potential through tyrosinase inhibition assay and the activation capacity of cell longevity protein (SIRT1) of GCE were compared to pure E-resveratrol and E-ε-viniferin. Drug-likeness of GCE polyphenols were calculated, allowing the prediction of skin permeability and bioavailability. Finally, the present data enabled the consideration of GCE from polyphenol-rich varieties as multifunctional cosmetic ingredients in accordance with green chemistry practices.
