    (2008-07) Abdissa, Negera; Fiseha, Ashebir (PhD)
    The stem bark of Ekebergia capensis is used traditionally by people of east Wollega for the treatment of Lung TB and its smoke is used to attract Bees if bee hives are activated with it. From the stem bark of Ekebergia capensis, one flavonoid EC-3 was isolated along with two acyclic triterpenoids namely 2, 3, 22, 23- tetrahydroxy- 2, 6, 10, 15, 19, 23- hexamethyl- 6, 10, 14, 18- tetracosatetraene (EC-1) and 2- hydroxymethyl 2, 3, 22, 23- tetrahydroxy-6, 10, 15, 19, 25- pentamethyl- 6, 10, 14, 18- tetracosatetraene (EC-2). The structural determination was accomplished by means of spectroscopic methods (IR, UV, 1D and 2D) NMR.
