AMARO-LUIS, Juan M.; AMESTY, Ángel E.; MONTEALEGRE, Roger  and  BAHSAS, Alí. Rospiglioside, a New Totarane Diterpene from the Leaves of Retrophyllum rospigliosii. J. Mex. Chem. Soc [online]. 2006, vol.50, n.3, pp.96-99. ISSN 1870-249X.

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.

Keywords : Retrophyllum rospigliosii; Podocarpaceae; diterpenes; abietane; totarane.
