The Viola Tolosa project

Funded jointly by the Midi-Pyrénées Regional Council, with support from the Toulouse City Council, the Viola Tolosa project associates three Toulouse-based research laboratories: the INRA-INP Joint Research Unit for Agro-Industrial Chemistry (INP-ENSIACET), the Pharmaceutical Chemistry and Pharmacology for Development Laboratory (IRD-UPS) and the Plant Science Research Laboratory (CNRS-UPS) at Université Paul Sabatier, as well as Groupe BERDOUES and the Toulouse Municipal Greenhouses.  It aims to drive the development of a new economic sector for violet growing in the Midi-Pyrénées region, with particular focus on cultivating the Violet of Toulouse under favourable environmental and economic conditions.

To achieve this objective, this project will adopt a dual scientific strategy:

  • analysis of violet flower fragrances as a chemotaxonomic tool, with a view to the rapid and pertinent differentiation of 120 violet species/varieties from the National Violet Collection, housed in the Toulouse Municipal Greenhouses;
  • characterisation of the chemical potential of the Violet of Toulouse, based on the principles of green chemistry and plant fractionation, an evaluation of the biological activities (anti-oxidant, anti-microbial, cytotoxic, etc.) of the extracts obtained, and ultimately, the acquisition of natural extracts in a form that will meet the needs of industry (fractionated, purified, etc.).

In early 2016, the Viola Tolosa project is entering its operational phase, because of the availability of a shade canopy in the greenhouses that will enable production of the plant material necessary for studies in the laboratory and the start of a PhD thesis at Université Fédérale Toulouse Midi-Pyrénées on this subject (2015-2018)
