Chemical Sciences
Synthesized interesting ionones, campholene nitriles; investigated extracts, essential oils of L.cyanescens, Fruit plants (P. guajava, T.catappa, I.gabonensis, S.mombin, C.albidum, A.occidentale, G.arborea), which are good sources of terpenoids. Studied chemical constituents, bioactivities of essential oils from medicinal plants. Currently into isolations, characterizations, bioactivities of metabolites in promising ethno-medicinally utilized Nigerian plants.
