Purification by Macroreticular Resin of Procyanidines from Mangosteen Shell
The adsorption and desorption performances for procyanidins from mangosteen shell were studied in this paper. The optimum resin was selected from ten macroreticular resins, and the static adsorption and dynamic adsorption conditions for it were studied. The results showed that XDA-7 resin was the best for procyanidins from mangosteen shell and the optimal conditions were as follow: adsorption flow 2 BV/h, elution agent (ethanol) concentration of 60%, and washing flow 2 BV/h, elution agent volume 6 BV. Under the proposed conditions, the purity of procyanidins from mangosteen shell was 66.20%.
