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
