Conclusions

  1. 1.

    The molecular weight of the compound studied is determined by the most intense ion peak with maximum m/e value which, as a rule, is the ion peak, with m/e (M - 60)+..

  2. 2.

    The ratios of the peaks for the molecular ion and (M-AcOH) ion of esters of 24-nor- and 21,24-dinorchola-5,16,20 (22)-trienic acids (IV)–(VI) depends on the stereochemistry at the Δ20(22) bond.

  3. 3.

    The presence of ion peaks with m/e 213 and 226 is characteristic for compounds containing hydroxyl and/or acetoxy groups at C-16 and C-17.
