Natural Products and Marine Bioresource Development


  • Qualitative and quantitative analysis of high value natural products from marine sources, particularly focused on polyphenols and pigments in seaweeds and seagrasses
  • Chemical analysis of marine deep-sea materials collected in Norway
  • Bioprospecting and search for novel compounds
  • Chemical ecology, biosystematics studies and interdisciplinary applications

Monica Jordheim´s main research interests are to enhance scientific knowledge and application value of various natural products. Jordheim has over twenty years of experience in quantification and identification of natural products, inluding full molecular elucidation.

Because of the structural diversity, characterization of natural products requires an integrated analytical approach including optimized extraction techniques, multiple steps of chromatography, High Resolutions Mass spectrometry (HRMS) and high field NMR analysis.

Jordheim is the:

Jordheim is Head of Education at the Department of Chemistry, working with educational quality and development.


B.Sc. and M.Sc.-projects:

Organic analytical projects within bioprospecting and marine bioresource development (seaweeds (harvested and farmed), seagrasses, aquatic angiosperms, deep sea materials). Severel of the projects have industrial partners. 



KJEM235 https://www.uib.no/emne/KJEM235    (10 ECTS)

Objectives and Content

The course addresses analysis of organic compounds using spectroscopic methods as infrared (IR), ultraviolet-visible (UV-Vis) and nuclear magnetic resonance (NMR) spectroscopy, as well as mass spectrometry (MS). The course concentrates on interpretation of data, and the focus will be to understand and to utilize data from NMR and MS.
