<jats:p>Extraction of Pimelea simplex F. Muell. and P. decora Domin. has yielded flavone and several methoxyflavones of unusual oxygenation patterns: 2'-methoxyflavone and 7-methoxyflavone from P. simplex, and 3'-methoxyflavone, 6-methoxyflavone, 3',6-dimethoxyflavone and 2',3',6- trimethoxyflavonefrom P. decora. The structures of the substances were confirmed by synthesis from the corresponding chalcones. The 13C n.m.r, spectral data of the flavones and chalcones are tabulated.
