Abstract: front page image
(EN)The present invention relates to a process for purification of oxyresveratrol from the extracted solution of Artocarpus lakoocha Roxb through membrane separation. The product can be obtained in excellent yield up to 81% using water as extracting solvent and can be separated from the extract to up to 98% using nanofiltration membranes. Only the desired trans isomer is obtained and no cis isomerisation takes place during the extraction process.
