For the structural identification of monohydroxylated progesterones synthesized by microorganisms, a method was developed using a combination of high-performance liquid chromatography and electrospray ionization collision-induced dissociation mass spectrometry (HPLC/ESI-CIDMS). The retention times and MS/MS spectra of 11 different standards at 30 eV were collected and compared. The identification of D-ring-hydroxylated progesterones (15beta-, 16alpha-, 17alpha- and 21-OH-P) using ESI-CIDMS was not possible. However, they were separated chromatographically using a 65:35 mixture of water and acetonitrile containing 0.5% acetic acid. The other hydroxylated progesterones (2alpha-, 6beta-, 7beta-, 9alpha-, 11alpha-, 11beta-, and 19-OH-P) could be identified by comparison of eight fragments. The complete separation of 11 standards was achieved chromatographically. The developed assay was evaluated by the identification of monohydroxylated progesterones produced by CYP106A2 from Bacillus megaterium ATCC 13368.
