Abstract
Two novel rearranged clerodane diterpenoids, dugesinβ A (1) and dugesin B (2), were isolated from the aerial parts of Salvia dugesii, together with five known clerodane diterpenoids: isosalvipuberulin (3), salvipuberulin (4), tilifodiolide (5), salvifolin (6), and salvifaricin (7). Their structures were elucidated on the basis of different spectroscopic techniques. The isolation and identification of these compounds are significant from both biosynthetisis and chemotaxonomy points of view.
