Design Methodology for the Development of a New Cosmetic Active Based on Prunus domestica L. Leaves Extract

“…Cosmetics 2018, 5, x FOR PEER REVIEW 9 of 20 A positive relationship between the anti-oxidant activity of fractions F3, F5 and F6 and the occurrence of compounds eluting in the phenolic / flavonoid region was found ( Figure 4). Even though some further phytochemical analysis is needed to properly characterise the compounds constituting these fractions, one can mention the identification of kaempferol, quercetin and rutin, as well as some of their respective glycosylated derivatives in this eluting region from several P. domestica extracts previously studied by our research team [6]. Such observations are also consistent with correlations between chemical composition and bioactivities reported in the literature [9,[23][24][25][26][27].…”

“…These new environmentally-friendly habits offer valuable advantages: (a) reusing such "waste" material to get as much value as possible from every resource, which offers a unprecedented degree of traceability on the materials' origin as sourcing channels already exist and are secured [5]; (b) developing the potential of waste to be used as raw material enables the diversification of value chains for one single market segment and may subsequently imply the growth of farmers/producers' incomes, hence strengthening those sourcing channels; and (c) they constitute furthermore fantastic communication opportunities and with the appropriate marketing strategy, cosmetic brands can really connect with customers through their mutual responsibility toward the environment preservation and gain new market shares.This article presents a procedure to design efficient cosmetic ingredients while meeting the challenging consumer's demands for sustainability, naturality, transparency and traceability.In order to integrate those sustainability values into our process of ingredients' development and to take advantage of the "green" phenomenon, we accessed a wide range of by-products that were extracted using several solvents. Given the promising results already shown by our research team regarding leaves of Prunus domestica L. (Rosaceae) [6], special attention was brought to the potentiality to create valorisation channels for by-products of the plum industry (food usages mainly: fresh, canned or dried fruits, more processed products, etc. ).Prunus domestica L. is a species of flowering plant that includes many varieties of plum trees.…”

Antiviral Activity Against Infectious Bronchitis Virus and Bioactive Components of Hypericum perforatum L.

“…This corresponds to the fragmentation regularity of quercitrin (Oliveira et al, 2014). Moreover, a quasi-molecular ion [M–H] − at 301.72 m/z confirms the presence of the quercetin (Stierlin et al, 2018) ( Figure 12C ). In addition to a positive quasi- molecular ion at 543.29 m/z [M+Na] + ( Figure 12D ) and a negative quasi-molecular ion [M–H] − at 519.08 m/z ( Figure 12E ), confirming the presence of the pseudohypericin.…”

Kinase-Based Screening of Marine Natural Extracts Leads to the Identification of a Cytotoxic High Molecular Weight Metabolite from the Mediterranean Sponge Crambe tailliezi

“…Finally, each crude organic extract was analyzed by HPLC/ESI-MS/MS in both positive and negative ion modes (see [50] for details on the methods used).…”
