Analysis and laboratory works

The phytochemical analysis and the laboratory work come together with selection and domestication works and cultivation techniques, but can also be carried out on request.

  • Identification of pathogens and pests
  • Germination tests and dormancy shift on seeds
  • Preservation and multiplication in vitro
  • Determination of essential oils
  • Artemisinin assay
  • Analysis of anti-oxydant activity (FREC)
  • Analysis of anti-radical activity (DPPH)
  • Active principle analysis (TLC)
  • Microbiological analysis
  • Development of non-destructive analytic methods (NIRS)

Exemples

Tests on seeds

Seeds are nearly always the starting point of our selection works and afterwards, the diffusion mode of the new varieties to producers.

Mastering the seeds production in quality and quantity is essential. Our researches about this theme mainly focus on the optimal germination parameters (photo and thermoperiodism), on the dormancy phenomenon, the viability and the preservation of seeds.

The sanitary quality is also tackled with the resarch of disinfection techniques suited to the production method (usual or organic).

In vitro laboratory

The in vitro cultivation of micro-cuttings allows us to preserve in controlled sanitary conditions the « star » plants issued from our selection works.

It also gives us the opportunity to vegetatively multiply species that are difficult to propagate otherwise.

Artemisinin analysis

The quantification of wanted secondary metabolites is often one of the main indicators for the selection and putting into culture works.

Reseraching simple, reliable, quick and cost-effective techniques is sometimes an important stake for these agronomic works. Thus for artemisinin extracted from Artemisia annua, we achieved the development and validation, with other laboratories, of an efficient quantification protocol through thin-layer chromatography (TLC)

Our laboratory now carries out these analysis as a routine service supply.
