Abietane diterpenoids from Salvia rubescens ssp. truxillensis

Abstract:

From aerial parts of Salvia rubescens ssp. truxillensis the abietane diterpenes carnosol, 11,12-di-O-methylcarnosol, 16-hydroxycarnosol, rosmanol and 16-hydroxy-7-methoxyrosmanol have been isolated and identified on the basis of spectral data. An exhaustive analysis of the uni- and two-dimensional 1H- and 13C-NMR spectra of 16-hydroxy-7-methoxyrosmanol, allowed the revision of previously assignment on some 1H- and 13C-NMR signals. The above refereed 16-hydroxylated diterpenes are reported for the second time as natural products.
