can boast to have most - if not all - necessary experience and
facilities close at hand
for dealing with projects involving plant compounds.
The academic setting provides an optimal environment for its goals.
only does the collaboration ensure an up-to-date handling of projects,
it also gives the opportunity to use the extensive range of University
facilities available. Many of these are invaluable when it comes to
determination, structure elucidation and/or isolation of natural
There are, for instance, wide-ranging facilities for literature studies
and for the fractionation of complex mixtures (like plant extracts),
especially through Centrifugal
Partition Chromatography (CPC), a technique that has been
used extensively for many years now. Many spectrometric
methods are available for the identification of isolated
compounds. Good results have been obtained in fractionation of natural
extracts and in the purification and structure elucidation of active
