RESEARCH INTERESTS

Natural Products Research of Medicinal Plants and Fungi using chemotaxonomic and ethno botanical information. Compounds of interest include; limonoids, alkaloids, lignans, triterpenoids, coumarins flavonoids and quassinoids. Focus will be on isolation and structural determination based on spectroscopic techniques and biological activities of these compounds.
