title: Preliminary separation and purification of resveratrol from extract of peanut (Arachis hypogaea) sprouts by macroporous adsorption resins.
abstract: In the present study, the separation and purification characteristics of resveratrol from extract of peanut sprouts (PSE) on 11 macroporous adsorption resins were investigated. The results showed that ADS-5 offered better adsorption and desorption capacity for resveratrol than other tested resins. From the static experiments with ADS-5 resin, we found that the experimental data fitted best to the pseudo-second-order kinetics model and Langmuir isotherm model, and the adsorption was a spontaneous and endothermic process. The separation and purification parameters of resveratrol from PSE were optimised by dynamic adsorption/desorption experiments with the column packed with ADS-5 resin. Under the optimal conditions, after one run treatment with ADS-5 resin, the content of resveratrol in the product was increased 17.9-fold from 1.32% to 23.60%, with a recovery yield of 88.33%. The results demonstrated that ADS-5 resin was a promising basis for large-scale preliminary separation and purification of resveratrol from PSE.
