A novel terpenoid hydroquinone named glaziovianol (1) and three known compounds 6-formyl-2-methoxy-9-methyl-7,8-dihydro-1, 4-phenanthrenedione, ent-19-oxo-16betaH-kauran-17-oic acid, and rel-8alpha-hydroxy-5-hydroxymethyl-2-methoxy-8a-methyl-7,8,8a, 9-tetrahydro-1,4-anthracenedione were isolated from the EtOH extract of Auxemma glazioviana wood. The structures were established using spectroscopic analysis (1D and 2D NMR, MS, IR).
