%X Two new naphthoquinones, 8-&#91;(2&#8242;E)-3&#8242;,7&#8242;-dimethylocta-2&#8242;,6&#8242;-dienyl&#93;-2,7-dihydroxynaphthalene-1,4-dione (1) and 2-hydroxy-6,7-dimethoxy-3-methylnaphthalene-1,4-dione (2), and one known naphthoquinone, (+)-teretifolione-B (3), were isolated from the roots of Conospermum sphacelatum Hook. (Proteaceae) collected in central Queensland. The structures of compounds (1) and (2) were determined by spectroscopic analysis.
