Natural Bioatives & Circular Economy Lab


Patricia Rijo



In the scientific domain of Natural Bioactives & Circular Economy, three main areas are prominent:

— Natural Bioactives, encompassing Natural Products chemistry, Extraction optimization, isolation, structural characterization, Molecular Design, Semi-synthesis of Bioactive Molecules & Structure-Activity Relationship studies, and Bioactives analysis and quantification using techniques like HPLC, GC, and FTIR analysis.

— Computational modeling, plays a pivotal role in discovering novel molecules, understanding the drug’s mode of action and development the molecule’s potency within a rational drug design framework and providing predictive models on various processes within this domain.

— Ionic Liquids, focusing on their synthesis and new applications, contributing to sustainable practices and circular economy initiatives.


Natural Products chemistry/isolation/purification/characterization

Several laboratory supplies, equipment, and bench space are available for carrying out common isolation and purification using chromatographic techniques including analytical and semi-preparative HPLC-DAD and BUCHI Chromatography.







BUCHI Cromatography



Routine chromatographic analysis for identification and quantification of polar and nonpolar compounds (only with standards available). Development, implementation and validation of HPLC-DAD / FTIR / GC-FID  methods
