Abstract
As part of our study on the bioactive agents from Pentaclethra macrophylla tree, P.Benth (oil bean tree), 13- benzyl ethyl methyl abietate was isolated from its leaves. The structure was elucidated using spectra obtained from NMR spectroscopy in combination with IR and MS. its molecular formula is C26H32O2 with molecular weight 376, calculated for M/z 375.29. The IR spectrum showed absorptions of aliphatic carbon, (2924.85, 2855.09cm-1), carbonyl group, (1736. 68 cm -1), aromatic (1457.97 cm-1) and ether (1466.20 cm-1). The fragmentation pattern was also determined
