Exudates collected from 65 species of gymnosperms and angiosperms were examined by solid-state carbon-13 (13C) nuclear magnetic resonance (NMR) spectroscopy. Diagnostic criteria were developed to distinguish resins, gums, and gum resins. The typology generated from the exudate spectra generally follows current taxonomic classifications, suggesting that 13C NMR spectroscopy may have applications in exudate identification, at least at the familial level, and in some cases at the generic or specific levels.
