Infrared Studies and Mineral Element Analysis of the leaf of Vernonia amygdalina

Title variants
Languages of publication
Infrared characterization of column eluates and elemental analysis of V. amygdalina was carried out as a preliminary view of the chemical and mineral element composition of the leaf of this plant. Infrared analysis of the five pure eluates obtained revealed that they contained saturated aliphatic esters, nitro-groups conjugated with benzene ring, secondary amines/nitrogen heterocycles, 1,3-disubstituted benzene and oxazine/oxazoline fragments respectively. These molecular fragments are major building blocks of many medicinal compounds. Potassium, magnesium and sodium were the major minerals in the leaf, while copper, zinc, iron, nickel, manganese and chromium occurred in trace amounts. These findings are pointers to the diverse use of the leaf extract in traditional medicine. Research attention should therefore focus on the chemistry of this plant for the full exploration and exploitation of its obvious antibiotic and mineral values.
