The mass spectra of a number of natural (II, IV, XII) and modified kaurenolides (I, III, V to XI) are reported. The major fragmentations of these compounds occur by rupture of the ring B to give fragments B and C, both of which contain the ring A. In the case of the 7‐hydroxycompounds (II and III) their mass spectra are markedly different due to the difference in configuration at C 7 .
