摘要:
Esters of flavonoids, including flavones, flavonols, flavanones, flavanols, flavanolols, isoflavones, anthocyanins, proanthocyanidins, chalcones, aurones and hydroxycoumarins conjugated by an ester bond to a ω-substituted C6 to C22 fatty acid are provided. The esters may be used in cosmetic, pharmaceutical, and nutritional preparations.
摘要:
Disclosed is a method for enzymatic synthesis of esters of flavonoid and flavonoid derivatives, according to which a reaction medium containing an organic solvent, a glycosylated flavonoid or aglycon flavonoid, an acyl group donor, and an enzymatic catalyst is produced, b) additional quantities of flavonoid and/or acyl donor are optionally added during the reaction, and c) the obtained esters are separated from the enzymatic particles and the solvent. The inventive method is characterized by maintaining the concentration of water and/or alcohol which are formed during the reaction to below 150 mM. Advantageously, the molar ratio of flavonoid to acyl donor in the reaction medium is maintained in the range from 0.01 to 20.00 during the reaction.

摘要:
A process is provided for the production of glycogens or an extract rich in glycogens from yeast cells, and a cosmetic composition containing them. A given quantity of yeast cells, from a specific culture or recovered as residues of a fermentation process, is subjected to an operation of enrichment in intracellular glycogens by culturing in two phases in the presence of a carbon source. The metabolism of the yeast cells is then stopped. The membranes of the yeast cells are then at least partially disintegrated to free intracellular substances, and the freed intracellular substances are subjected to at least one precipation to precipitate glycogens. A cosmetic composition comprising the glycogens is formulated in admixture with a dermatologically acceptable excipient.
