Mass spectrum
Momordica triterpenoid ester (Figure 3) showed
molecular ion m/z = 715.6640 in micrOTOF
corresponding to the molecular formula C51H71O2.
Molecular ion abstracted ethyl group, m/z = 687.6309.
Triterpenoid ester in the first part corresponded to the
molecular formula C27H36O2, m/z = 392.0133.
Triterpenoid ester in the second part corresponded to
molecular ion abstracted two methine groups and two
hydrogen radical species, m/z = 301.0238, one carbonyl
group and eight hydrogen radical species, m/z =
259.8830, and molecular ion abstracted two carbonyl
groups, one ethyl group and two hydrogen radical
species, m/z = 236.9562.9
