The laboratory uses various techniques such as extraction, fractionation, semi-synthesis, enzymatic, and molecular biology to identify and characterise the novel compounds. Potent compounds will be carried forward to evaluate for their mechanisms of action in-vivo with our local and international collaborators.
The used of a sustainable and green extraction method for natural products is required in the modern age to minimize environmental impact and ensure the safety of human beings. One of the ways is to reduce and replace the use of the toxic, flammable and corrosive solvents in the extraction processes. The use of solvent less system, supercritical fluids and ionic liquids have been advocated as an alternative method to replace the notoriously unfavourable organic solvents. Supercritical carbon dioxide extraction offers alternative means for extraction of natural products. It has been used to extract value added bioactive compounds such as α-tocopherol, hyperforin and carotenoids. Our laboratory is interested to optimise factors that potentially governed the extraction processes and extraction of novel molecules from the natural resources.
We are keen to work together with researchers from different fields. Prospective postgraduate students with or without funding are welcome to discuss your research interest and work together with us.
