UHPLC–DAD–MS/MS fingerprints recorded by the Engström method for the galloyl units (blue chromatograms) and HHDP units (red chromatograms) detected in eight Eucalyptus species in the study by Marsh et al.23 The spider webs show the proportional tannin composition (HT % versus PA %), the proportional hydrolyzable tannin composition (galloyl % versus HHDP %), and the proportional PA composition (PC % versus PD %) in all of the samples, as quantified from the tannin fingerprints.
