My research foci are phytochemistry, anti-inflammatory constituents of plants and roles of plant antioxidants in cancer, anti-microbial, and other inflammatory conditions. Currently, my lab is working on these research areas:
This project seeks to investigate the bioactive constituents which confer wound healing properties to the traditional plant Monodora myristica. Firstly, the work will focus on validating the use of the plant as an antibacterial, antioxidant and anti-inflammatory agent. The petroleum ether, ethyl acetate and methanol extracts of the leaf, stem bark and fruit of the plant will be assessed for their in vitro antibacterial effect using both the agar well diffusion and microbroth dilution assays. Rapid screening of antioxidant effect on TLC plates, free radical scavenging activity using DPPH, lipid peroxidation assay, total phenol content and antioxidant capacity assays will be employed to assess the antioxidant effects of the various plant parts. Anti-inflammatory activity will be determined using the carrageenan-induced oedema model in chicks. Based on the observed activities, the active fractions will be selected for further screening.
This study involves bioassay-guided isolation and characterization of the cytotoxic and antiproliferative constituents of the bark and ripe pod of Tetrapleura tetraptera using modern analytical separation (p-HPLC) and spectroscopic (e.g. UV/VIS, IR) techniques.
