    Phytochemical Investigation on the Stem Bark of Croton Macrostachyus (Bisana)
    (Addis Ababa Universty, 2007-07) Yibralign, Zelalem; Fiseha, Ashebir (PhD)
    The Croton macrostachyus is used for the treatment of malaria, venereal diseases, cough, diabetes, constipation, tape worms and hepatitis. The dichloromethane extract of the stem bark of Croton macrostachyus was afforded two Terpenoids: the compound with full structure which is a triterpenoid (CM-1) and a compound with a partial structure which is a tetratrpenoid (CM-2). Structural determination was accomplished by means of spectroscopic methods (IR, UV, 1D and 2D NMR)
