Two new naphthoquinones, (2 R )‐6,8‐dihydroxy‐ α ‐dunnione ( 1 ), 6,8‐dihydroxy‐2,7‐dimethoxy‐3‐(1,1‐dimethylprop‐2‐enyl)‐1,4‐naphthoquinone ( 2 ), together with three known compounds, (2 R )‐6,8‐dihydroxy‐7‐methoxy‐ α ‐dunnione ( 3 ), nevadensin ( 4 ), and lysioside C ( 5 ), were isolated from the whole plant of Lysionotus pauciflorus. Their structures were established by spectroscopic methods. Hydroxylated naphthoquinones are reported to occur in a Lysionotus species for the first time. The cytotoxic activities of compounds 1 – 3 were evaluated in vitro against a panel of tumor cell lines.
