Hotel Description

We are experts in natural products chemistry. This includes the isolation, identification and if necessary structural elucidation of metabolites and components of diverse natural products. We specialize in plants but our experience is also extended to fungi and microorganisms.
In the last 10 years we have become a leading group in Plant Metabolomics, focusing especially on secondary metabolites profiling. We apply a metabolomic approach to diverse fields of natural product chemistry including medicinal herb quality control, plant ecology, development of antibiotics using microbes, detection of bioactive compounds in material from plants, fungi, marine products and others.
We also specialize in general phytochemical methods of isolation, identification and fractionation of natural products.
In the last 5 years, we have opened a new field of research in our group aimed at developing media for green chemistry. Our greatest achievement is the development of Natural Deep Eutectic Solvents that can completely replace or partially substitute toxic organic solvents as a media for production/extraction or conservation.
