Unlocking the access to oxidized coenzyme A via a single-step green membrane-based purification.

A new membrane-based strategy to purify oxidized coenzyme A ((CoAS)) from adenosine triphosphate (ATP), adenosine diphosphate (ADP) and adenosine monophosphate (AMP) has been developed. Commercially available membranes were screened and studied (permeate flux and overall compounds retention) which allowed the identification of one efficient membrane (GK from Suez Water Technologies & Solutions). Different total compounds concentrations solutions were used in the system in order to find the following working conditions: 4 bars with a total compounds solution of 5.

Phenolic Compounds Extracted from Cherry Tree ( Branches: Impact of the Process on Cosmetic Properties.

Cherry tree branches ( var Rosaceae) are agricultural by-products that are often neglected, yet they are rich in phenolic compounds and highly appreciated for their numerous biological activities. Extracts of cherry tree branches were evaluated for their use in cosmetics, particularly for their antioxidant, anti-tyrosinase, and antimicrobial activities. Samples were obtained by accelerated solvent extraction (ASE) at different ethanol percentages and different temperatures.

Implementation of an Enzyme Membrane Reactor to Intensify the α--Glycosylation of Resveratrol Using Cyclodextrins.

The -glycosylation of resveratrol increases both its solubility in water and its bioavailability while preventing its oxidation, allowing a more efficient use of this molecule as a bioactive ingredient in pharmaceutical and cosmetic applications. Resveratrol -glycosides can be obtained by enzymatic reactions. Recent developments have made it possible to selectively obtain resveratrol α-glycosides from the β-cyclodextrin-resveratrol complex in water with a yield of 35%.
