ResumoTricyclic diterpenes with the abietane skeleton have been isolated from the aerial parts of Hyptis dilatata. In addition to 12 well known compounds, two new compounds have been isolated and identified as 11,12 diacetoxy-7β-methoxy-8,11,13-abietatrien-20,6β-olide (epimethylrosmanol) and 11,12 diacetoxy-7β-ethoxy-8,11,13-abietatrien-20,6β-olide (epiethylrosmanol). Their structures have been determined by spectroscopic methods using 2D correlation experiments (1H–13C) HMBC and HMQC. Esquirolin B with the pimaran skeleton has been isolated as well.
