Simultaneous determination of prostaglandins E1, A1, and B1 by reversed-phase high-performance liquid chromatography for the kinetic studies of prostaglandin E1 in solution.
A method for the simultaneous determination of prostaglandins E1, A1 and B1 (PGE1, PGA1 and PGB1) in solution has been developed by reversed-phase high-performance liquid chromatography using a 3 microns C18 column. The mobile phase consisted of 35% acetonitrile in 0.002 M phosphate buffer (pH 3.5) and its flow-rate was 1.5 ml/min. Quantitative measurement was performed using a photodiode array detector system at 190, 220, and 280 nm for PGE1, PGA1 and PGB1, respectively. The method has been applied to the primary kinetic studies for reaction profile for PGE1----PGA1----PGB1 at 60 degrees C in pH 2.0, 7.2, 10.0 and 12.0 buffer solutions.
