A new glucosyl totarane diterpene named rospiglioside, together with seven known abietane and totarane diterpenes identified as ferruginol, sugiol, sugiol acetate, totarol, totarol acetate, 4β-carboxy-19-nortotarol and 16-hydroxy-4β-carboxy-19-nortotarol have been isolated from the leaves of Retrophyllum rospigliosii (Pilger) C. N. Page (Podocarpaceae). The structure of rospiglioside was established on the basis of spectroscopic methods, mainly 1D- and 2D-NMR experiments.

De las hojas del Retrophyllum rospigliosii (Pilgre) C. N. Page (Podocarpaceae) fue aislado un nuevo glucosil diterpeno de la serie del totarano denominado rospigliósido, y siete diterpenos conocidos de las series del abiertano y del totarano identificados como ferrugino, sugio, acetato de sugio, totarol, adetato de totarol, 4β-carboxi-19-nortorato y 16-hidroxi-4β-carboxi-19-nortotarol. La estructura del rospigliósido fue establecida sobre la base de métodos espectroscópicos, principalmente experimentos de RMN uni- y bidimensionales.

Quatro sesquiterpenos do tipo eudesmano foram isolados das partes aéreas de Verbesina turbacensis e foram caracterizados por métodos espectroscópicos incluindo experimentos bidimensionais de RMN.

Four eudesmane sesquiterpene were isolated from the aerial parts of Verbesina turbacensis and were characterised by spectroscopic methods, including 2D NMR experiments.
