Abstract: The title compound, C₁₈H₁₆O₆, was isolated from Salvia hypoleuca. Except for one methoxy C atom, all non-H atoms are approximately coplanar. C-HO hydrogen bonds generate a centrosymmetric R₂²(14) dimer. Inversion-related molecules are stacked along the b axis with significant - interactions.
