Pungent Aromatic Compound from New Zealand LiverwortHymenophyton flabellatum

摘要

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