Mass spectra were recorded
from 30–450 m/z. Individual components were identi-
fied by matching their 70 eV mass spectra with those of the
spectrometer data base using the Wiley L-built library and
two other computer libraries MS searches using retention indices
as a pre-selection routine (Alencar et al., 1990), as well as
by visual comparison of the fragmentation pattern with those
reported in the literature (Adams, 2001).
