The mass spectra of arnifolin and [D]arnifolin have been obtained, and the fragmentation of arnifolin under the action of electron impact has been studied.

A scheme of the fragmentation of arnifolin explaining the main peaks in its mass spectrum has been put forward. The mass spectrum agrees well with the structure established for this substance.
