69th Inaugural lecture of the University of Nigeria entitled, “From the Lab Bench through the Gardens to the Apothecary: Journey So Far”.

## Research contributions

Osadebe (with her team) has researched extensively on natural products extraction, isolation and characterization, and has isolated lead structures from Loranthus micranthus and Alchornea cordifolia. Extracts and isolates from mistletoe exhibited anti-diabetic, antioxidant, immunomodulatory and antimicrobial activities. She did establish parabolic relationship between a chromatographic-based partition coefficient parameter (Rm) and LD$_{50}$(Index of acute toxicity).The relationship enables LD$_{50}$ of newly synthesized members in a series to be determined without sacrificing more experimental animals. She holds two Bulgarian patents on method of synthesis of some antispasmodic gamma-amino propanols.
