Mass spectral studies on prostaglandins. II--Prostaglandins E1 and E2.
The mass spectroscopic behaviour of the methyl ester of prostaglandins E1 and E2 has been studied with the aid of low eV spectra, measurements on metastable ion decompositions and high resolution mass measurements. Mechanisms are proposed for the formation of the majority of the abundant fragment ions of these biologically important compounds. The mass spectra of free acids are also discussed.
