Two novel rearranged clerodane diterpenoids, dugesin 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.
