  • Notes:

  • a In the sealed vessel aqueous extracts, see Figures 4, 5. The chromatograms contained additional peaks whose associated extractables could not be identified; for example, peaks 1, 16.

  • b In the reflux, IPA/Water extracts, see Figure 7.

  • c In solvent extracts, Soxhlet and reflux, see Figure 10. The LC chromatograms also revealed numerous peaks that were associated with fatty acid epoxides. Additional peaks in the chromatograms could not be ascribed to a specific compound.

  • d The identifications for the specific compounds are either confident or confirmed.

  • e A peak for this compound was observed in the MS + ion chromatogram, which is not shown in this article.
