Notes:
↵a In the sealed vessel extracts, see Figures 20 and 21. These extracts also contained extractables whose identities could not be established, specifically peaks 3, 6, 8, 9, 14, 15, and 19.
↵b In the solvent extracts, Soxhlet and reflux, see Figure 24. The chromatogram also contained peaks whose associated substance could not be identified.
↵c These identifications are classified as either confident or confirmed.
↵d Tentative identification.
↵e This peak was present in the extract chromatogram but was not labeled in the relevant figure.
