Naturally-occuring compounds

CONTEXT :

Naturally-occurring compoundsMany living organisms are able to produce natural substances with highly-diverse chemical characteristics, and with very varied toxicological and nutritional properties.

 

Thus, some chemical compounds produced by plants can be toxic in the short or long term, while still possessing medicinal qualities that are useful for health (for example, alkaloids).

 

Other groups of substances such as glucosinolates may be undesirable in certain situations (for example in the rape used in animal feeds), but beneficial in other cases (e.g. anticarcinogenic properties attributed to certain vegetables such as broccoli).

 

Lastly, a third group of substances known as polyphenols is universally beneficial to the health, even though in some cases (for example, certain high-risk groups) excessive consumption can result in health problems (for example, phytoestrogens).


ROLE OF CODA-CERVA :

CODA-CERVA has many years' experience in analysing highly diverse natural substances of plant origins, such as polyphenols, alkaloids and glucosinolates.

High-performance analytical tools (UPLC-MS/MS) and expertise in synthetic pathways and in describing the various forms present in vegetables (aglycons and glycosylated forms) are great strengths that enable researchers to take part in research work and to provide services for many different clients.

  • ELABORATING OF NEW METHODS AND SERVICES

A method has been worked out with a view to being able to determine by UPLC-MS/MS the main molecules of interest (for example: genistein, daidzein, the active ingredients in Ginkgo biloba, Maca alkaloids) present in plant-based products and food supplements. Naturally-occurring compounds

Analyses can be performed by request (contact : A. Callebaut )

  • RESEARCH

CODA-CERVA is involved in a number of research projects dealing with the presence of beneficial or unwanted natural compounds in food supplements (FOODINTER project), also in animal feeds and brassicaceæ (OFFQ project).
