Methodology: The ethanol extract of the dried leaves was partitioned between chloroform and water (1:1), then the chloroform fraction was further partitioned between petroleum ether (60-80°C) and aqueous methanol (1:1). Column chromatography of the chloroform fraction over silica gel (200 mesh) by a gradient elution technique from petroleum ether to chloroform, followed by methanol was carried out. Results: A yellow solid 0.22 g was isolated which was characterized by employing IR, 1D and 2D Original Research Article Njoku et al.; ACSJ, 12(4): 1-5, 2016; Article no.ACSJ.19929 2 NMR techniques spanning H, C, H-H COSY, H-C COSY, HMBC and TOF ESI-mass spectrometry.
