We describe here a modified protocol for the simultaneous quantification of specific eicosanoids formed during stimulation of human platelets in vitro with adenosine diphosphate. The eicosanoids thromboxane B(2) (TXB(2)), arachidonic acid (AA), 12-R-hydroxyeicosatetraenoic acid (12-R-HETE), 12-S-hydroxyheptadecatrienoic acid (12-S-HHTrE) and the internal standard prostaglandin B(1) (PGB(1)) were extracted from human platelets by liquid-liquid extraction using ethyl acetate. This was followed by derivatization and fluorescent detection prior to analysis by reversed phase liquid chromatography. The high-performance liquid chromatographic method consisted of ODS reversed-phase column (3 microm) and a mobile phase of acetonitrile-water (85:15). TXB(2) and AA plasma calibration curves were linear between 6.25 and 125 ng mL(-1) (r(2) > 0.997), whereas for 12-R-HETE and 12-S-HHTrE the curves were linear between 5.0 and 40 ng mL(-1) (r(2) > 0.998). All calibration curve standards had <15% CV (coefficient of variation) and between-run precision, and the percentage relative deviation for replicate (n = 6) quality controls was less than 5.5%. The method was adapted to allow the screening of drugs that may affect either one or both of the lipoxygenase and cyclo-oxygenase pathways.
