Department: Pharmacognosy

Status: Senior Lecturer

Academic/Professional Qualifications: B. Pharm., M.Sc., M.Phil., Ph.D (Pharmacognosy)

Research Area: Phytochemistry and antidiabetic studies of Nigerian Medicinal Plants

Professional Accomplishments:

My research has provided scientific justifications to the ethnomedicinal anti-inflammatory, anti-microbial, anti-ulcer, anti-sickling and anti-diabetic claims of some Nigerian medicinal plants. My work has also demonstrated the possible contribution of antioxidant activities of some medicinal plants to their antidiabetic effect.

Contributions to Knowledge:

Pharmacological establishment of the antidiabetic uses of some African medicinal

plants and insulin release as an additional mechanism of hyperglycaemia-lowering activity of Eugenia uniflora leaves. Identification of stigmasterol, kaurene diterpenoids, lupeol-3-acetate as some of the hyperglycaemia-lowering constituents of Senecio biafrae, Xylopia aethiopica and Chrysophylum albidum, respectively. Identification of the antihyperglycaemic constituents of Terminalia superba, Massularia acuminata and Globimetula Braunni. The contribution of some plant antioxidants to their antidiabetic activities as exemplified by Eugenia uniflora, Entandrophragma cylindricum and Triclisia subcordata, Carica papaya and Citrullus lanatus seeds and Sansevieria liberica.
