Four sesquiterpenoids compounds, oplopanone, 1α, 4β, 7β-trihydroxyeudesmane, 1α, 4β, 7α-trihydroxyeremophilane and 1α, 4β, 7βtrihydroxyeremophilane, were isolated from the rhizomes of H. sagittifolia. Their structures were elucidated by means of spectroscopic data interpret ation, mainly 1D, 2D NMR, IR and mass spectrometry. 168 3rd ICYC 2010 Universiti Sains Malaysia NAT-O9 NON-VOLATILE ISOLATES OF TWO HETEROPYXIS SPECIES 1,4 23rd-25th June 2010 AMA Mohammed, PH Coombes, 1 1,2 NR Crouch and 1,3 DA Mulholland 2 School of Chemistry, University of KwaZulu-Natal, Westville Campus, Durban, 4000, South Africa Ethnobotany Unit, South African National Biodiversity Institute, PO Box 52099, Berea Road 4007, South Africa 3 Division of Chemical Sciences, Faculty of Health and Medical Sciences, University of Surrey, Guildford, Surrey GU2 7XH, United Kingdom 4 Department of Chemistry, Alzaeim Alazhari University, P O Box 1432, Khartoum, Sudan E-mail: [email protected] 1 During the course of this study, the genus Heteropyxis was moved, on botanical grounds, from the family Heteropyxidaceae to the Myrtaceae, where it is now the sole genus of the subfamily Psiloxyloideae and it comprises only three species: H. canescens Oliver, H. natalensis Harvey and H. dehniae Susseng.
