EXTRASYNTHESE produces chemically-defined substances from plants. These substances can help you to identify and/or assay a marker in a plant, plant extracts or a medicinal product. They can also allow you to start or progress experimental studies in highly specialised fields of research into pharmacology, cosmetics, agrifood products (bio-activity, bioavailabilities, metabolisation studies…).
The composition of medicinal and/or dietary plants can naturally fluctuate considerably : differences in organoleptic characteristics, in taste, in aroma ...
For the quality monitoring of your starting materials (plants, plant extracts, cosmetic products …), we propose to establish their phytochemical profile on the basis of one or more markers selected from amongst our numerous reference substances and thus allow you to ensure the reproducibility and compliance of the profiles from one batch to another.
There are several different types of marker : active ingredients, active markers, analytical markers and negative markers. The markers must be of the required quality for the chromatographic or spectrophotometric techniques used and comply with the requirements of the user or of the supervisory body.

| A range of products with the GREEN LABEL specially prepared for analytical controls. They are easy to find in the alphabetical list through their code ending with the letter "S". This letter "S" provides an insurance that specific care has been taken in the course of their production in such a way as to guarantee a similar analytical response between one batch and another. They are delivered with their chromatographic condition of use. In order to help you establish your analysis files, we propose a range of GREEN LABEL products where the article code from the 9000 series does not include the "S" letter. These products are delivered, for each batch supplied, with complementary structural elements - infrared, mass, nuclear magnetic resonance and ultraviolet spectrum … | A range of products with the RED LABEL for R&D. These are technical products for numerous applications: hemisynthesis, biochemistry, toxicological studies and objectivation studies, etc… In no case, can these products be used for purposes of quantitative analysis without complementary analyses by yourselves. We would draw your attention to the fact that, we have not made physiological activity or toxicity tests for any of our products. The range proposed in this catalogue has been designed for laboratory use for analytical or research purposes |
Our products are marketed in packaging units or in multiples of the sales-unit. Special pricing will be proposed for any quantity in excess of 10 sales-units.
