The positive ion mass spectrum of dogibberic acid was examined and fiagmentation routes involving the carbon skeleton are proposed on the basis of mass measurements and metastable ion observations. The results are compared with the mass spectra of 3-hydroxy-epidogihberic acid, as well as gibberellin
