摘要：

Mass spectra (including high resolutions) of bakkenolides and their derivatives (I-X) were measured and the common fragmentation patterns discussed with the help of metastable ions. Fragmentation of B-A(I) is characterized by a McLafferty-type rearrangement, whereas oxygen functions at 1 and 9-positions of B-A take part in the fragmentation of bakkenolides-B, C, D and E. © 1969.
