The solubility and molar absorptivity of trans- and cis-resveratrol isomers in aqueous solvents are poorly described. This study aimed to develop and describe a new simple method for the determination of trans- and cis-resveratrol concentrations in aqueous solutions. Up to 300 microM trans-resveratrol was dissolved in water by sonication for 2h. Cis-resveratrol was obtained by exposing a 100-muM trans-resveratrol aqueous solution to sunlight for 8h, followed by HPLC separation and analysis by… CONTINUE READING
