Mass spectra of steroids having a lactone-side chain

The mass spectra of different steroidal compounds having a lactone-side chain were recorded. The fragmentation pattern of the tetracyclic steroid system is not modified by the structure of the lactone ring. Except for parent ion value and the losses of the substituents at C-3 and C-20, the method is...
