Abstract in English
Phytochemical investigations carried out on ethanolic extract from woods of Araucaria angustifolia resulted on the isolation and identification of vanillin, p-hydroxybenzaldehyde, coniferaldehyde; two isoflavones (cabreuvine and irisolidone); four lignans (pinoresinol, eudesmine, lariciresinol and 9'-O-lariciresinolacetate), and β-sitosterol. Its callus culture was showed to accumulate mixtures of isomers E and Z of octadecyl p-cumarate and of octadecyl ferulate.
