Line diagrams of GC-MS low resolution mass spectra are presented for the methyl esters of gibberellins A1 to A24 and for the trimethylsilyl ethers of the methyl esters of the hydroxylated gibberellins A1 to A8, A10, A13, A14, and A16 to A23. These reference spectra allow conclusive identification of the presently known gibberellins without access to authentic specimens. The utility of the mass spectra of these derivatives in structural diagnosis of the gibberellins is discussed. High resolution measurement of the composition of fragment ions in selected trimethylsilyl ethers are included.
