Quantitative analysis of Z-2-[4-(4-chloro-1,2-diphenyl-but-1-enyl)phenoxy]ethanol in human plasma using high-performance liquid chromatography.

A highly sensitive and precise high-performance liquid chromatography (HPLC) assay was developed and validated for the quantitation of Z-2-[4-(4-chloro-1,2-diphenyl-but-1-enyl) phenoxy]ethanol (FC-1271a) in human plasma. Plasma samples (1.0 ml) containing FC-1271a and internal standard (toremifene citrate; Farestono) were extracted using a 2% 1-butanol, 98% hexane solution with an extraction efficiency of >97%. Samples were reconstituted in methanol, irradiated with high intensity ultraviolet light (254 nm) for 1 min, and injected onto a C18 reverse phase column. Samples were eluted isocratically at a flow-rate of 0.5 ml/min with a mobile phase consisting of 6.5% water and 0.5% triethylamine in methanol. The fluorescence of photochemically activated compounds was detected using a fluorometer set at an excitation wavelength of 266 nm and emission wavelength of 370 nm. Under these assay conditions, standard calibration curves were linear through a concentration range of 10-400 ng/ml. In summary, we have developed and validated an HPLC assay to quantitate FC-1271a in human plasma.[1]
