The plant leaves were successively extracted into three (3) extract forms including aqueous extract, ethanolic extract and hydro!ethanolic (50:50 v/v) extracts. For quality control, high performance thin layer chromatography (HPTLC) was performed on extracts. Antiplasmodial activity was assessed 1 Corresponding Author: Dr (Mrs) Ehimwenma Sheena Omoregie Email: ehiomoregie@yahoo.co.uk; Tel. No.: +234 (0) 8023397020
