D hanks to its natural heritage, French Guiana, as part of the Amazon, is also a hot-spot for European and global plant biodiversity. However, the economy integrating this resource is in its infancy. However, many cultivated and wild species, as well as agroforestry products, are still used today in food and traditional medicines. Better knowledge of these species in terms of their chemical composition and biological activities, as well as their suitability for inclusion in formulations for food, cosmetic or pharmaceutical purposes, would promote economic and social development in line with regional policies to promote traditional knowledge and know-how, and meet society's expectations for natural, high-quality products.

Presentation

As part of the Amazon, French Guiana's natural heritage makes it a hot-spot for plant biodiversity in Europe and around the world. However, the economy integrating this resource is in its infancy. However, many cultivated and wild species, as well as agroforestry products, are still used today in food and traditional medicines. Better knowledge of these species in terms of their chemical composition and biological activities, as well as their suitability for inclusion in formulations for food, cosmetic or pharmaceutical purposes, would promote economic and social development in line with regional policies to promote traditional knowledge and know-how, and meet society's expectations for natural, high-quality products.

Research area(s)

The laboratory COVAPAM (Knowledge and Development of Amazonian Plants), the local team of UMR QUALISUD, aims to be a key player in the development of Amazonian plant biodiversity. Its research focuses are as follows:

  • Biological activities (antioxidant, anti-inflammatory, antimicrobial)
  • Phytochemical composition (polyphenols, fixed oils, volatiles, alkaloids)
  • Vectorisation/Formulation of active ingredients

Fields of application

  • food industry,
  • pharmaceutical,
  • cosmetics,
  • aromas and fragrances

Composition of the team in French Guiana (11 members, including 6 permanent staff)

Permanent members :
Jean-Charles ROBINSON (Professor of Biochemistry), Didier BEREAU (Senior Lecturer in Chemistry - HDR), Rudy COVIS (Senior Lecturer in Chemistry) and Louis-Jérôme LEBA (Senior Lecturer in Biology); Karine MARTIAL (Research Engineer); Gaël FREDERIC (Laboratory Technician);

Non-permanent members :
