%X A new natural naphthoquinone, lomandrone, has been isolated from Lomandra hastilis. Spectrometric analyses of this compound and its derivatives indicate the structure 2-ethyl-8-hydroxy-3,6,7-trimethoxy-1,4-naphthoquinone An alternative structure has been eliminated by synthesis of 6-ethyl-5-hydroxy-2,3,7-trimethoxy-1,4-naphthoquinone.
