-
Macroporous hypercrosslinked resin(Rf18) was synthesized from styrene and decorated by loading methyiamine(Rs3), N-methylacetamido(Rs4), dimethylamine(Rs5) and trimethylamine(Rs6) respectively. The adsorption and chromatographic separation of camptothecin and Vincoside-Lactam(VCS-LT) by the synthesized resins were compared. Their adsorption capacity and adsorption selectivity for camptothecin and vincoside-lactam were found to be remarkably increased. For quaternary ammonium resin(Rs6), the separation impact(αc/v) was 114. Camptothecin and vincoside-lactam could be effectively separated with resins Rf18 (Rs3, Rs5). But camptothecin could not be washed out from Rs6 with organic solvent, it could be easily washed out with acidic solution of 80% ethanol-water(pH=4).
