Senegalin (1), a new phenylpropanoid has been isolated from the stem bark of Ekebergia senegalensis A. Juss. along with twelve known secondary metabolites including coumarins 2–5, 4-hydroxy-3,5-methylbenzoic acid (6), pentacyclic triterpenoids 7–9, acyclic triterpenoids 10 and 11 and steroids 12 and 13, respectively. Their structures were elucidated with the help of spectroscopic techniques including 1 D- and 2 D-NMR. The antibacterial activity of the major compounds (2, 9–11) was evaluated on five bacterial strains. However, only compounds 2 and 11 showed a weak inhibition against Bacillus subtilis and Pseudomonas agarici. Furthermore, the chemotaxonomic significance of these compounds has also been elaborated.
