Abstract

The aerial parts of Salvia yosgadensis afforded five new terpenes with unusual skeletons, together with two known norditerpenes, ambreinolide and norambreinolide. The new compounds were elucidated as 6 alpha-hydroxyambreinolide, 6 alpha-hydroxynorambreinolide, 6 alpha-hydroxy-8 alpha-acetoxy-13,14,15,16-tetranorlabdan-12-oic acid, and two 19,20-dinorsesterterpenes, named as yosgadensonol and 13-epi-yosgadensonol. Their structures were determined by spectroscopic means, particularly by extensive 1D and 2D NMR studies.
