title: Pungent aromatic compound from New Zealand liverwort Hymenophyton flabellatum.
abstract: Ether extract of the New Zealand liverwort Hymenophyton flabellatum produced a pungent principle. The structure has been identified as known compound, 1-(2,4,6-trimethoxy-phenyl)-but-2(E)-en-1-one by means of its spectral data, previously isolated from the fern Arachinoides standishii. Further isolation of the extract of this species afforded eight aromatic compounds whose structures were determined by spectral analysis. Those compounds were shown to be biogenetically and structurally related to the pungent compound of this species.
