Resumen
Secoisolariciresinol monomethyl ether and lariciresinol-4-methyl ether were isolated from the knots of dead trees of Araucaria angustifolia. On the basis of spectral evidence, the position of the OH group was located in these compounds. The 13C NMR spectra of the phenyltetralin lignans galbulin, galcatin, isogalcatin and cyclogalgravin have also been recorded and the signals assigned, based on the methyl shifts of cyclogalgravin. © 1979. 18 10 1703 1708 Fonseca, Campello, Barata, Rúveda, (1978) Phytochemistry, 17, p. 499 Anderegg, Rowe, Lignans, the Major Component of Resin fromAraucaria angustifoliaKnots (1974) Holzforschung, 28, p. 171 Lüdemann, Nimz, 13C-kernresonanzspektren von ligninen, 2.
