GLC determination for ftorafur in biological fluids.
A GLC analysis for free ftorafur was developed to follow in drug disposition in body fluids of patients. The free drug was extracted from aqueous biological samples with chloroform, derivatized by methylation, and chromatographed on 1% HI-EFF 8BP using flame-ionization detection. The analysis is sensitive (0.25 microgram/ml of plasma) and specific for the intact molecule, and it does not interfere with subsequent fluorouracil analysis of the same sample.
