The performance of adsorption and chromatographic separation of camptothecine and vincoside-lactam by polymeric resins with different nanometer pores were studied.The static adsorption results show the adsorption capacity of vincoside-lactam is related to the specific area of the resin.The adsorption capacity of gel post-crosslinked resin with a specific area of 1 100 m2/g is larger than that of other two adsorbents.The adsorption discrepancy of Rf8 for camptothecine and vincoside-lactam was the most and the separation factor reached to 2.01.The dynamic desorption results show that macroporous post-crosslinked resin Rf8 with micropore and macropore structures and carbonyl group can separate camptothecine and vincoside-lactam effectively via chromatography,but macroporous resin ADS-5 and gel post-crosslinked resin X1 can not.Such effective chromatographic separation of camptothecine and vincoside-lactam with resin Rf8 is ascribed to the surface character and hole structure of the resin.
