The Chair for Fundamental Organic Chemistry is part of the Organic Chemistry
Section of the Department of Chemistry
The main role is to carry on teaching
at the graduate and undergraduate levels on various fields of organic chemistry.
These include basic Organic Chemistry for non-chemists,
Organic Chemistry, Stereochemistry,
Information in Chemistry,
Chromatographic Techniques,Laboratory
Techniques in Organic Chemistry, and Food
Chemistry. Periodic advanced short courses in chromatographic techniques
are offered. Ph.D. students, interested in the areas of chromatography and
biologically active natural compounds are offered the opportunity of sharing
the available facilities, equipment and expertise. An active participation
in EU research programs is part of the research activities and funding.
Facilities:
- Organic Chemistry Laboratories
- Laboratory for Natural Products Organic Chemistry
- Laboratory for High Resolution Gas Chromatography
- Laboratory for Gas Chromatography-Mass Spectrometry (ITD, Quadrupole)
- Laboratory for HPLC and HPLC-MS (Particle Beam)
- Laboratory for Gas Chromatography-Fourier Transform Infrared Spectrometry (GC-FTIR)
- Laboratory for Supercritical Fluid Extraction (SFE)
- Laboratory for Supercritical Fluid Chromatography (SFC) and Supercritical Fluid Chromatography-Mass

This group is led by Prof. H.J. Chaves das Neves.The main
interests lie in the isolation and identification of natural compounds
that show some kind of biological, activity: Plant-plant interactions (allelopathic
compounds), Clinical Chemistry (metabolic diseases), Chiral Separations
(Food Chemistry). About 100 research papers and communications have been
published up to this day.
- Allelopathic compounds from plants: Triticum aestivum and Arbutus unedo
- New HPLC methods for Amino Acid Analysis without derivatization
- Application of Chemometrics to the recognition of strawberry cultivars through aroma profiles
- On-line HPLC chiral detection (EU project MAT1-CT-930043)
