High-performance liquid chromatography [HPLC] procedures were developed which separate leukotrienes (LT), hydroxy-fatty acids (HETE), prostaglandins (PG), the stable metabolite of prostacyclin (6-keto-PGF1.alpha.), the stable metabolite of thromboxane A2 (TXB2), 12-hydroxyheptadecatrienoic acid (HHT) and arachidonic acid (AA). Two methods employing revere-phase columns are described. One method uses a radial compression system, the other a conventional steel column. Both systems employ methanol and buffered water as solvents. The radial compression system requires 60 min for separation of the AA metabolites, while the conventional system requires 100 min. Both methods provide good separation and recovery of 6-keto-PGF1.alpha., TXB2, PGE2, PGF2.alpha., PGD2, LTC4, LTB4, LTD4, LTE4, HHT, 15-, 12- and 5-HETE; and AA. The 5S,12S-dihydroxy-6-trans, 8-cis, 10-trans, 14-cis-eicosatetraenoic acid (5S,12S-diHETE), a stereoisomer of LTB4, coelutes with LTB4. To determine the applicability of the methods to biologic systems, AA metabolism was studied in 2 models, guinea pig lung microsomes and rat alveolar macrophages. Both HPLC systems demonstrated good recovery and resolution of eicosanoids from the 2 biological systems. A simple evaporation technique for HPLC, sample preparations, which avoids the use of chromatographic and other time-consuming methodology, is also described.
