My research interests deals with the isolation, identification and analysis of low-molecular substances in medicinal plants or herbal products with the aim to find a rationale for traditional usage of the plant and/or to find new lead compounds from Nature. Ethnopharmacology is an important approach for the selection of plants. Currently, my major areas of interest deals with the identification of phenolic compounds in plants used against cognitive impairments and type-2-diabetes, diseases related to inflammation and oxidative stress, and the use of traditonal Afrifan medicine against malaria.

Research projects:

  • Antioxidant and antidiabetes effects of extracts and phenolic compounds from Norwegian berries.
  • Isolation and characterization of natural products from medicinal plants used against cognitive diseases
  • Metabolomics and DNA barcoding of Indian medicinal plants
  • Antimalaria effects of African medicinal plants and their constituents
