Abstract: Objective :To establish a simple,rapid,sensitive column-switching HPLC method for the analysis of the 10-hydroxycamptothecin(HCPT) in human serum. Methods : A precolumn containing restricted access media(RAM) was used for the sample clean-up and trace enrichment and was combined with a C18 column for the final separation.The HCPT was monitored with fluorescence detector,excitation and emission wavelengths being 385 and 539 nm,respectively. Results : The analytical time was 8 minutes.There was a linear response range of 1-1 000 ng/mL with correlation coefficient of 0.998 while the limit of detection was 0.1 ng/mL.The intraday and interday variations were less than 5%. Conclusion : This analytic procedure has been applied to a pharmacokinetic study of HCPT in clinical patients and the pharmacokinetic parameters of one-compartment model were calculated.
