Mj. Delnozal et al., EXTRACTION PROCEDURES FOR THE HPLC DETERMINATION OF 5-FLUOROURACIL INBIOLOGICAL SAMPLES, Journal of liquid chromatography, 17(7), 1994, pp. 1621-1636
An extraction procedure was optimized for the reversed-phase high perf
ormance liquid chromatographic determination of 5-Fluorouracil in rabb
it plasma, liver, kidney, lung and heart samples. The extraction condi
tions are adapted to each type of matrix in order to achieve high extr
action yields (ca 90%) and interference-free chromatographic peaks.
