Abstract
Evidence is presented that the fully reduced derivatives of pimaric acid (I), sandaracopimaric acid (II), and isopimaric acid (III) have trans–anti–trans fused skeletons. The implications of this observation are discussed.

Abstract
Sandaracopimaric acid has been shown to be 7-epipimara-8(14), 18-dienoic acid (II), and Ukita's acid to be 7-epi-13β-pimara-9(14),18-dienoic acid (VI). A hydroxyl-containing acid from Sandarac resin is described.
