This study classifies modern and fossil resins using solid-state carbon-13 Nuclear Magnetic Resonance (NMR) spectroscopy. Researchers identified links between fossil resins and modern plants like Agathis and Hymenaea, aiding in origin determination.

Area of Science:

  • Paleobotany
  • Organic Geochemistry
  • Spectroscopy

Background:

  • Woody plants worldwide produce diterpenoid resins.
  • Resin fossilizes into amber over geological timescales.
  • Solid-state carbon-13 Nuclear Magnetic Resonance (NMR) spectroscopy is a key technique for material characterization.

Purpose of the Study:

  • To classify modern and fossil diterpenoid resins.
  • To establish relationships between fossil resins and modern plant genera.
  • To determine the geographical origin of fossil resins.

Main Methods:

  • Characterization of several hundred fossil resin samples using solid-state (13)C NMR spectroscopy.
  • Phenomenological classification of modern diterpenoid resins based on NMR spectra.

Related Experiment Videos

  • Comparative spectral analysis to link fossil resins to modern plant genera (Agathis, Hymenaea).

    • Main Results:

    • Identified distinct classes of modern diterpenoid resins via NMR.
    • Related a global group of fossil resins to the modern genus Agathis.
    • Linked fossil resins from the Americas and Africa to the modern genus Hymenaea.
    • Categorized European fossil resins into Baltic ambers and an Agathis-like group.
    • Demonstrated potential for geographical origin assignment of fossil resins based on NMR spectra.

    Conclusions:

    • Solid-state (13)C NMR spectroscopy effectively classifies diterpenoid resins.
    • Specific fossil resin groups are linked to modern genera Agathis and Hymenaea.
    • NMR analysis aids in tracing the origin of fossil resins, including those in archaeological contexts.
