Appendix B. Representative total phenolic profiles for (a) E. globulus and (b) E. tenuiramis using high-performance liquid chromatography (HPLC) chromatograms (3-D map of time vs. intensity vs. wavelength between 230 and 450 nm, where AU on the y-axis represents absorbance units).

 
   FIG. B1. Representative total phenolic profiles for (a) E. globulus and (b) E. tenuiramis using high-performance liquid chromatography (HPLC) chromatograms (3-D map of time vs. intensity vs. wavelength at 230–450 nm, where AU on the y-axis represents absorbance units). Flavonoids are apparent between 4 and 6.5 min as peaks with absorbance at ~370 nm. The peak just before 10 min at ~400 nm is degraded chlorophyll. UV spectra of peaks between 8 and 9 min in E. tenuiramis are not correct for clean FPCs, but mass spectrometry data show that some FPCs are present. Peaks between 7.5 and 11 min in E. globulus are largely FPCs.
