    Phytochemical Investigation on the Leaves of Leonotis Ocymifolia
    (Addis Ababa Universty, 2006-07) Asteraye, Yeshitila; Fiseha, Asebir (PhD)
    In this project, a phytochemical study has been undertaken on the leaves of Leonotis ocymifolia and the solvent extract of the plant has been conducted. Leonotis ocymifolia is indigenous to Eastern and Southern Africa and is occasionally cultivated for its medicinal uses, which include acting as ascaricide, an anticancer drug, and as a treatment for ulcers, wounds, obesity and eczema. The ethanol extract of the leaves of Leonotis ocymifolia led to the isolation of two compounds A and E. The structure of compound A was determined by means of spectroscopic methods (IR, 1H NMR, 13C NMR, and DEPT) but the structure of compound E could not be determined because of its small amount which led to see no carbon atom in its 13C NMR spectrum
